Factors of Compliance of Dental Patients in Primary Health Care Services during the Pandemic.

The compliance of dentists with good hygiene practices during the COVID-19 pandemic was essential to minimize the transmission of SARS-CoV-2 strains, and the pandemic has significantly interrupted the provision of oral health care to many individuals. We aimed to examine, in a cross-sectional study, factors affecting dental patients' compliance in primary dental health settings during the pandemic period. The present study was conducted on 300 dental patients visiting four private dental offices in the city of Larissa in Central Greece during the period October-December 2021. The patients in the study sample were of an average age of 45.79 years with a standard deviation of 15.54 years, and 58% of the sample were females. A significant proportion of the participants, 22%, reported that they would be influenced if they knew that the dentist had been ill with COVID-19 despite being fully recovered. A total of 88% of the participants reported that they would feel safe if they knew their dentist was vaccinated against COVID-19. Regarding the information received by dentists, 88% of the participants agreed that the dentist's role is important in dealing with the COVID-19 pandemic, and 89% of them agreed that the information they received from the dentist about the COVID-19 pandemic was sufficient. One-third of the total sample reported that COVID-19 negatively impacted keeping dental appointments, and 43% of the sample kept scheduled appointments. A total of 98% reported that the dentist followed all health protocols against COVID-19 and that their office was equipped to follow health protocols. In the present study, we observe that dentists had adequate knowledge of, attitudes towards, and practices of infection control protocols against COVID-19 during the second wave, according to patients' perceptions.

International nurse education research collaboration during the COVID-19 pandemic: Researchers' perspectives.

BACKGROUND: International research collaborations in nurse are increasing. However, collaborations in international nurse education research are limited compared to clinical nurse studies. This paper presents the experiences of seven investigators of a multi-country study while conducting collaborative research among nurse students across five continents. OBJECTIVE: This paper aims to describe the experiences and challenges of conducting an international nurse education research and to propose recommendations to enhance these collaborative research experiences. METHODS: Narrative perspectives from nurse educators on the international nurse collaborative experience were described in this discussion paper. RESULTS: International collaboration in nurse education research was a positive and enriching experience. While several challenges were experienced by the collaborators, the presence of facilitating factors, benefits of collaboration, and opportunities for personal and professional growth and development outweighed the challenges. Team leader attributes, active engagement, commitment, genuine interest, and cultural sensitivity are essential in creating a successful international nurse research project. CONCLUSION: International collaborative nurse research fosters expansion of nurse knowledge through sharing of expertise and development of culturally diverse perspectives.

Work place and prevalence of COVID-19 in a rural population in Greece.

INTRODUCTION: Coronavirus disease-19 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become a global pandemic, giving rise to a serious global health threat. Many countries including Greece have seen a two-wave pattern of reported cases, with a first wave in spring and a second in autumn of 2020. METHODS: A cross-sectional seroprevalence study was designed to measure the prevalence of IgG antibodies with a quantitative SARS-CoV-2 IgG lab-based serology test, chemiluminescent microparticle immunoassay, against novel coronavirus in rural areas in Greece after the second pandemic wave. The study was conducted on 29 January 2021 in a rural semi-closed area, the municipality of Deskati, prefecture of western Macedonia in Greece after the second pandemic wave. RESULTS: Sixty-nine participants were included in this study. The present study demonstrated a high prevalence of COVID-19 infection (31 of 69 total participants; 45%) and those who were working in the public sector were at higher risk of COVID-19 infection in comparison to their counterparts in private sector (p=0.05364), (relative risk 2.64; 95% confidence interval 1.001-7.086). CONCLUSION: The study presents data showing a high prevalence of herd immunity for COVID-19 in a semi-closed area in Greece. These findings might help to understand the characteristics of this second wave, the behaviour and danger of SARS-CoV-2 in rural areas in Greece and Europe generally.

The Comparative Superiority of SARS-CoV-2 Antibody Response in Different Immunization Scenarios.

Background: Both SARS-CoV-2 infection and/or vaccination result in the production of SARS-CoV-2 antibodies. We aimed to compare the antibody titers against SARS-CoV-2 in different scenarios for antibody production. Methods: A surveillance program was conducted in the municipality of Deskati in January 2022. Antibody titers were obtained from 145 participants while parallel recording their infection and/or vaccination history. The SARS-CoV-2 IgG II Quant method (Architect, Abbott, IL, USA) was used for antibody testing. Results: Advanced age (>56 years old) was associated with higher antibody titers. No significant differences were detected in antibody titers among genders, BMI, smoking status, comorbidities, vaccine brands, and months after the last dose. Hospitalization length and re-infection were predictors of antibody titers. The individuals who were fully or partially vaccinated and were also double infected had the highest antibody levels (25,017 ± 1500 AU/mL), followed by people who were fully vaccinated (20,647 ± 500 AU/mL) or/partially (15,808 ± 1800 AU/mL) vaccinated and were infected once. People who were only vaccinated had lower levels of antibodies (9946 ± 300 AU/mL), while the lowest levels among all groups were found in individuals who had only been infected (1124 ± 200 AU/mL). Conclusions: Every hit (infection or vaccination) gives an additional boost to immunization status.

Lessons We Have Learned Regarding Seroprevalence in High and Low SARS-CoV-2 Contexts in Greece before the Omicron Pandemic Wave.

BACKGROUND: Antibody seroprevalence in rural communities remains poorly investigated. We compared the SARS-CoV-2 seroprevalence in two Greek communities in June and July 2021 after the end of the Delta-driven pandemic wave that started in November 2020. One community was affected worse than the other. METHODS: The SARS-CoV-2 IgG II Quant method (Architect, Abbott, IL, USA) was used for antibody testing. RESULTS: We found a high rate of SARS-CoV-2 seropositivity in both communities, approaching 77.5%. In the area with a higher burden of COVID-19, Malesina, seropositivity was achieved with vaccine-acquired and naturally acquired immunity, whereas in the low-burden context of Domokos, the high rates of seropositivity were achieved mainly with vaccination. Previously infected individuals were less likely to be vaccinated than previously uninfected adults. The antibody titers were significantly higher in previously infected, vaccinated participants than in unvaccinated ones. In total, 4% and 10% of the unvaccinated population were diagnosed seropositive for the first time while not knowing about the previous infection. Age and gender did not impact antibody titers in high- or low-burden contexts. CONCLUSIONS: Before the Omicron pandemic wave, herd immunity was reached in different contexts in Greece. Higher antibody titers were measured in infected vaccinated individuals than in infected unvaccinated ones.

THE IMPACT OF MENTAL HEALTH, SUBJECTIVE HAPPINESS AND RELIGIOUS COPING ON THE QUALITY OF LIFE OF NURSING STUDENTS DURING THE COVID-19 PANDEMIC.

OBJECTIVE: The aim of this study is to examine the effect of psychological distress and religious coping in quality of life of nursing students during the second wave of the pandemic in Greece. PATIENTS AND METHODS: Materials and methods: A cross-sectional online survey was conducted among nursing students. Data were collected via an e-survey consisting of five parts including HADS Questionary, SF-36, B-RCOPE and Subjective Happiness scale. RESULTS: Results: From the total of 200 nursing students the 86.5% were female, 35.5% were in their first year of study, 54% were single and 65.5 were urban residents. 51.9% of the students were experiencing anxiety and 31,5% were depressed. In regard to subjective happiness, the mean value was 4.51±1.27. In addition, the majority of the students consider themselves unhappy (67.5%). Finally, in regard to SF-36 scores, we observed that PCS mean score was 68.49±13.19, MCS56.12±24.23. Depression, as well as negative religious coping, can have a negative effect on both physical and mental health components of quality of life. CONCLUSION: Conclusions: Nursing students experience very high levels of stress and anxiety during the COVID-19 pandemic and need support and guidance to better manage stress and fear in this unusual situation.

Perceived Symptoms, Mental Health and Quality of Life after Hospitalization in COVID-19 Patients.

Patients recovering from novel coronavirus are reporting a variety of symptoms such as cough, dyspnea, myalgia as well as psychological distress and poor quality of life. The aim of this study is to assess quality of life and psychological distress in COVID-19 survivors and the sociodemographic and clinical characteristics that affect COVID-19 survivors' mental health status and quality of life. A quantitative study was conducted among COVID-19 survivors, who had previously been admitted to the University Hospital of Larissa, Greece. Data were collected via a questionnaire consisting of three-parts. The first part consisted of questions about the demographic characteristics. The second part was the SF-36 QoL index. The third part was the Symptom Checklist-90r (SCL 90-R). In addition, clinical information such as the length and the department of hospitalization, days since discharge and pulmonary function (spirometry values) were recorded. From a total of 145 patients, 60% were male, aged 59.72 ± 12.74 and 78.6% of them were married; the majority had completed secondary education, 35.9% were pensioners and 58.6 were living in urban areas. The most frequently reported symptoms were fatigue (67.6%) and pain (44.8%) and 11.7% were experiencing psychological distress. Pain, loss of smell, mandatory education, ICU admission, female gender and the experiencing of skin disturbance are associated with poor physical QoL among COVID-19 recovered patients. Greek COVID-19 previously hospitalized patients were reporting several symptoms associated with COVID-19. Good QoL and mental health were also reported. Physical pain, loss of smell and female gender were associated with poor QoL and psychological distress.

Containment and therapeutic relationships in acute psychiatric care spaces: The symbolic dimensions of doors

Background: There is an increasing trend of door locking practices in acute psychiatric care. The aim of the present study was to illuminate the symbolic dimensions of doors in Greek mental health nurses' experiences of open and locked working spaces. Results: A sequential mixed-method designexplored the experiences of nurses working in both open and locked psychiatric acute care units. Participants experiences revealed four types of doors related to the quality of recovery-oriented care: (a) the open door, (b) the invisible door, (c) the restraining door, and (d) the revolving door. Open doors and permeable spacesgenerated trust and facilitated the diffusion of tension and the necessary perception of feeling safe in order to be involved in therapeutic engagement. When the locked unit was experienced as a caring environment, the locked doors appeared to be "invisible". The restraining doors symbolized loss of control, social distance and stigma echoing the consequences of restrictingpeople's crucial control over spaceduring the COVID-19 pandemicin relation toviolence within families, groups and communities. The revolving door (service users' abscondence/re-admission) symbolised the rejection of the offered therapeutic environment and was a source of indignation and compassion fatigue in both open and locked spaces attributed to internal structural acute care characteristics (limited staffing levels, support, resources and activities for service users) as well as 'locked doors' in the community (limited or no care continuity and stigma). Conclusions: The impact of COVID-19 restrictions on people's crucial control of space provides an impetus for erecting barriers masked by the veil of habit and reconsidering the impact of the simple act of leaving the door open/locked to allow both psychiatric acute care unit staff and service users to reach their potential.

Defining Antibody Seroprevalence and Duration of Humoral Responses to SARS-CoV-2 Infection and/or Vaccination in a Greek Community.

BACKGROUND: In this work, we aimed to evaluate antibody-response longevity to SARS-CoV-2 infection and/or vaccination in one of the Greek communities that was worst hit by the pandemic, Deskati, five months after a previous serosurveillance and nine months after the pandemic wave initiation (October 2020). METHODS: The SARS-CoV-2 IgG II Quant method (Architect, Abbott, IL, USA) was used for antibody testing. RESULTS: A total of 69 subjects, who previously tested positive or negative for COVID-19 antibodies, participated in the study. We found that 48% of participants turned positive due to vaccination. 27% of participants were both previously infected and vaccinated. However, all previously infected participants retained antibodies to the virus, irrespective of their vaccination status. The antibody titers were significantly higher in previously infected participants that had been vaccinated than those who were unvaccinated and in those that had been previously hospitalized for COVID-19 than those with mild disease. CONCLUSIONS: Antibody responses to SARS-CoV-2 infection were maintained nine months after the pandemic. Vaccination alone had generated an immune response in almost half of the population. Higher antibody titers were found in the case of vaccination in previously infected subjects and especially in those with severe disease leading to hospitalization.

Investigating the prevalence of cognitive impairment in mild and moderate COVID-19 patients two months post-discharge: Associations with physical fitness and respiratory function

Background The aim of our study was to investigate the prevalence and associations of cognitive impairment in previously COVID-19 patients 2 months after discharge. Method Our study included previously hospitalized, consecutive COVID-19 patients with mild to moderate disease, followed up 2 months post discharge at a tertiary hospital?s outpatient clinic during May 2021. Exclusion criteria included intensive care unit admission, intubation, or a history of neurodegenerative disease and stroke prior to COVID-19. Prior to inclusion, eligible patients had provided written informed consent. The full battery of measurements in our study included demographics, medical and family history, anthropometrics, the 6-minute walk test (6MWT), the Borg Dyspnea Scale, spirometry, the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), the Short Form 36 health Survey (SF-36), the Montreal Cognitive Assessment (MoCA) and the Symptom Checklist 90-R (SLC90-R), reactive oxygen metabolites (dROMs) and plasma antioxidant capacity (PAT test;FRAS5, Parma, Italy). Cognitive impairment was considered on a MoCA cutoff ≤24. Data are presented as mean ±SD or Frequencies (%). Correlations between continuous data were assessed via the Spearman?s Rho correlation coefficient, whereas associations were assessed via multiple linear regression (MLR) models. For all tests, a p-value <0.05 was considered statistically significant. Results A total of 32 subjects were included in the study (35 Male, 17 Female;Mean age of 61.6±9.4). A total of 56.2% presented with cognitive decline (CD) as indicated by a MoCA score <24. Principal component analysis revealed that short-term memory impairments and multidomain impairment without short-term memory deficits were the predominant patterns of cognitive impairment. MoCA score correlated with age (?=-0.513, p=0.003), waist circumference (?=-0.388, p=0.028) waist to hip ratio (?=-0.361, p=0.042) and SpO2 during 6MWT (1st, 4th and 6th minute;p<0.05). MLR indicated that after adjusting for age and gender, SpO2 at the 6th minute of the 6MWT was independently associated with MoCA score (Beta=0.579, p-value=0.001). Conclusion Our findings indicated that among 32 outpatient clinic subjects, 56.2% presented with cognitive decline. The associations with oxygen saturation and physical condition as detected by the 6MWT may indicate overlap with post-COVID-19 fatigue and warrants further investigation.

Wounded healers during the COVID-19 syndemic: Compassion fatigue and compassion satisfaction among nursing care providers in Greece

Abstract Purpose The aim of this study was to investigate compassion fatigue (CF) and compassion satisfaction (CS) in nursing care providers in COVID-19 units. Methods A mixed-method study with 105 nurses. Results 23% of participants reported high CF risk while 77% expressed high to moderate potential for CS. Adequate preparation/education, clear and accountable leadership, and team sharing of feelings, experiences, and responsibilities during the transition in the COVID-19 unit helped participants to deal with overwhelming anxiety which if unattended could bring about frustration and long-lasting feelings of powerlessness. Practical Implications In the face of the present and future pandemics, there is a clear need to prepare healthcare organizations and nursing care providers to cope with the emotional content of public health emergencies while protecting themselves and avoid absorbing unmanageable emotions.

Determinants of Influenza Vaccination Coverage among Greek Health Care Workers amid COVID-19 Pandemic.

In the context of the evolving current COVID-19 pandemic, influenza vaccination among the public and health care workers is of particular importance. There are sparse data on the influenza vaccination coverage among health care workers amid COVID-19 pandemic. We aimed to study possible factors associated with influenza vaccination coverage among Greek physicians, dentists, and pharmacists during the flu season 2020-2021. We formulated the hypothesis that COVID-19 pandemic exerted a positive impact on the influenza vaccination coverage of health care workers. An online survey was conducted among the members of the Larissa, (Thessaly, Central Greece) Medical, Dentists, and Pharmacists Associations. The influenza vaccination coverage was 74% (251/340). Acceptance of COVID-19 vaccination coverage was the only factor independently associated with the likelihood of influenza vaccination coverage. In conclusion, we report here a considerable improvement of the influenza vaccination coverage among HCWs and especially among physicians. Acceptance of COVID-19 vaccination was the only predictor of influenza vaccination coverage. This finding provides public health workers and policymakers with useful policy-relevant evidence in order to maintain and even further improve the gains of increased vaccination coverage achieved during the flu season 2020-2021.

Eight Weeks Unsupervised Pulmonary Rehabilitation in Previously Hospitalized of SARS-CoV-2 Infection.

The aim of our study was to determine the impact of unsupervised Pulmonary Rehabilitation (uns-PR) on patients recovering from COVID-19, and determine its anthropometric, biological, demographic and fitness correlates. All patients (n = 20, age: 64.1 ± 9.9 years, 75% male) participated in unsupervised Pulmonary Rehabilitation program for eight weeks. We recorded anthropometric characteristics, pulmonary function parameters, while we performed 6 min walk test (6 MWT) and blood sampling for oxidative stress measurement before and after uns-PR. We observed differences before and after uns-PR during 6 MWT in hemodynamic parameters [systolic blood pressure in resting (138.7 ± 16.3 vs. 128.8 ± 8.6 mmHg, p = 0.005) and end of test (159.8 ± 13.5 vs. 152.0 ± 12.2 mmHg, p = 0.025), heart rate (5th min: 111.6 ± 16.9 vs. 105.4 ± 15.9 bpm, p = 0.049 and 6th min: 112.5 ± 18.3 vs. 106.9 ± 17.9 bpm, p = 0.039)], in oxygen saturation (4th min: 94.6 ± 2.9 vs. 95.8 ± 3.2%, p = 0.013 and 1st min of recovery: 97.8 ± 0.9 vs. 97.3 ± 0.9%), in dyspnea at the end of 6 MWT (1.3 ± 1.5 vs. 0.6 ± 0.9 score, p = 0.005), in distance (433.8 ± 102.2 vs. 519.2 ± 95.4 m, p < 0.001), in estimated O2 uptake (14.9 ± 2.4 vs. 16.9 ± 2.2 mL/min/kg, p < 0.001) in 30 s sit to stand (11.4 ± 3.2 vs. 14.1 ± 2.7 repetitions, p < 0.001)] Moreover, in plasma antioxidant capacity (2528.3 ± 303.2 vs. 2864.7 ± 574.8 U.cor., p = 0.027), in body composition parameters [body fat (32.2 ± 9.4 vs. 29.5 ± 8.2%, p = 0.003), visceral fat (14.0 ± 4.4 vs. 13.3 ± 4.2 score, p = 0.021), neck circumference (39.9 ± 3.4 vs. 37.8 ± 4.2 cm, p = 0.006) and muscle mass (30.1 ± 4.6 vs. 34.6 ± 7.4 kg, p = 0.030)] and sleep quality (6.7 ± 3.9 vs. 5.6 ± 3.3 score, p = 0.036) we observed differences before and after uns-PR. Our findings support the implementation of unsupervised pulmonary rehabilitation programs in patients following COVID-19 recovery, targeting the improvement of many aspects of long COVID-19 syndrome.

Understanding COVID-19 Epidemiology and Implications for Control: The Experience from a Greek Semi-Closed Community.

BACKGROUND: We aimed to estimate the SARS-CoV-2 antigen and antibody seroprevalence in one of the worst-affected by the pandemic semi-closed communities in Greece, Deskati, and evaluate the sociodemographic and clinical correlations of functional antibody responses. METHODS: The Ag2019n-CoV V1310/V1330 Rapid Test (Prognosis Biotech, Greece) was used for antigen detection. The Rapid Test 2019-nCoV Total Ig, V1210/V1230 (Prognosis Biotech, Greece), and the SARS-CoV-2 IgG II Quant method (Architect, Abbott, Illinois, USA) were used for antibody testing. RESULTS: None of the participants had a positive antigen result. SARS-CoV-2 seropositivity ranged from 13% to 45% in the study population, depending on the method. One-third of the participants with known past infection had a positive antibody test result 77 ± 13 days after infection. Two-fifths of infections determined by serology were asymptomatic. The advancing age and hospitalization predicted seropositivity among patients with past infection. Half of the participants who tested positive for antibodies were not aware of past infection. CONCLUSIONS: High-burden contexts in Greece, such as Deskati, are not so far from herd immunity thresholds. We highlighted the value of low-cost serosurveys targeting both symptomatic and asymptomatic populations to evaluate the natural immune response to SARS-CoV-2 in nonvaccinated susceptibles and design evidence-based policies for lifting lockdowns.

The Impact of the Lockdown Caused by the COVID-19 Pandemic on the Fine Particulate Matter (PM2.5) Air Pollution: The Greek Paradigm.

INTRODUCTION: Responding to the coronavirus pandemic, Greece implemented the largest quarantine in its history. No data exist regarding its impact on PM2.5 pollution. We aimed to assess PM2.5 levels before, during, and after lockdown (7 March 2020-16 May 2020) in Volos, one of Greece's most polluted industrialized cities, and compare PM2.5 levels with those obtained during the same period last year. Meteorological conditions were examined as confounders. METHODS: The study period was discriminated into three phases (pre-lockdown: 7 March-9 March, lockdown: 10 March-4 May, and post-lockdown period: 5 May-16 May). A wireless sensors network was used to collect PM2.5, temperature, relative humidity, rainfall, and wind speed data every 2 s. RESULTS: The lockdown resulted in a significant drop of PM2.5 by 37.4% in 2020, compared to 2019 levels. The mean daily concentrations of PM2.5 exceeded the WHO's guideline value for 24-h mean levels of PM2.5 35% of the study period. During the strictest lockdown (23 March to 4 May), the mean daily PM2.5 levels exceeded the standard 41% of the time. The transition from the pre-lockdown period into lockdown or post-lockdown periods was associated with lower PM2.5 concentrations. CONCLUSIONS: A reduction in the mean daily PM2.5 concentration was found compared to 2019. Lockdown was not enough to avoid severe exceedances of air pollution in Volos.

Comparing the Impact of COVID-19 on Nurses' Turnover Intentions before and during the Pandemic in Qatar.

BACKGROUND: Although several studies examining nurses' turnover intentions have been conducted, few studies have been conducted to explore how COVID-19 contributes to nurses' turnover intentions. This study aims to compare nurses' turnover (TO) intentions before and during COVID-19. METHODS: The cross-sectional study was conducted using the Turnover Intention Scale (TIS-6) and a convenience sample of participants from the largest healthcare provider in Qatar between August and September 2020. RESULTS: A total of 512 nurses were included in the final analysis. The majority were between 31 and 40 years of age (61.5%), 67.6% were females, 76.4% were married, 79.7% had a BSN, 43% had less than 5 years of experience, and 60.4% had worked in COVID-19 designated facilities. The turnover intentions were higher compared with before COVID-19 (p < 0.01). CONCLUSION: Nurses in Qatar have higher TO intentions during COVID-19. The participants' characteristics and stress levels are playing a major role in nurses' decision to leave during COVID-19. Understanding the factors that contribute to turnover intentions is crucial for workforce planning, especially during pandemics.

Acceptability of COVID-19 Vaccination among Greek Health Professionals.

Health Care Workers are at the front line of the fight against Covid-19. The aim of this study was to evaluate the acceptability of vaccination against COVID-19 among health professionals (physicians, dentists, pharmacists) two weeks prior to the start of the Greek vaccination campaign against COVID-19. A cross-sectional online survey was conducted over the period 15-22 December 2020 in 340 health professionals in Central Greece. We found a high level of acceptance for COVID-19 vaccine (78.5%) and a high vaccination coverage for the influenza vaccine (74%). Age > 45 years (OR = 2.01; 95% C.I. = 2.01-4.3), absence of fear over vaccine safety (OR = 4.09; 95% C.I. = 1.36-12.3), and information received from the Greek public health authorities (OR = 11.14; 95% C.I. = 5.48-22.6), were factors independently associated with the likelihood of COVID-19 vaccination acceptance. Our study indicates a high level of the COVID-19 vaccination acceptance among physicians, dentists and pharmacists. Nevertheless, several interventions can be implemented to increase acceptance of vaccine among health-care workers (HCWs) and could be especially directed at younger and vaccine-hesitant health care workers due to fear of vaccine side-effects. Last, our results provide some evidence that receiving vaccine-related information from the Greek Center for Diseases Control (E.O.D.Y.) could reduce the drivers of hesitancy and enhance the acceptability of COVID-19 vaccination.

Repeated Antigen-Based Rapid Diagnostic Testing for Estimating the Coronavirus Disease 2019 Prevalence from the Perspective of the Workers' Vulnerability before and during the Lockdown.

BACKGROUND: No previous study has investigated the SARS-CoV-2 prevalence and the changes in the proportion of positive results due to lockdown measures from the angle of workers' vulnerability to coronavirus in Greece. Two community-based programs were implemented to evaluate the SARS-CoV-2 prevalence and investigate if the prevalence changes were significant across various occupations before and one month after lockdown. METHODS: Following consent, sociodemographic, clinical, and job-related information were recorded. The VivaDiag™ SARS-CoV-2 Antigen Rapid Test was used. Positive results confirmed by a real-time Reverse Transcriptase Polymerase Chain Reaction for SARS-COV-2. RESULTS: Positive participants were more likely to work in the catering/food sector than negative participants before the lockdown. Lockdown restrictions halved the new cases. No significant differences in the likelihood of being SARS-CoV-2 positive for different job categories were detected during lockdown. The presence of respiratory symptoms was an independent predictor for rapid antigen test positivity; however, one-third of newly diagnosed patients were asymptomatic at both time points. CONCLUSIONS: The catering/food sector was the most vulnerable to COVID-19 at the pre-lockdown evaluation. We highlight the crucial role of community-based screening with rapid antigen testing to evaluate the potential modes of community transmission and the impact of infection control strategies.

Assessment of Knowledge, Attitudes, and Practices towards New Coronavirus (SARS-CoV-2) of Health Care Professionals in Greece before the Outbreak Period.

INTRODUCTION: The ongoing severe acute respiratory syndrome (SARS)-CoV-2 pandemic has expanded globally. The aim of the current study is to investigate the knowledge, attitudes, and practices (KAP) of health care professionals in Greece towards SARS-CoV-2. METHODS: From 10-25 February 2020, 500 health care workers were approached. Knowledge, attitudes, and practices towards SARS-CoV-2 were assessed via a personal interview questionnaire. For knowledge, each correct answer was given 1 point; attitudes, or concerns aimed at prevention of SARS-CoV-2 infection, and practices, or behaviors towards performing preventive practices, were assigned 1 point each. Points were summed and a score for each category was calculated. RESULTS: A total of 461 health care workers returned the questionnaire and were included in the analysis (mean age ± SD: 44.2 ± 10.78 years, 74% females). The majority were nurses (47.5%), followed by physicians (30.5%) and paramedics (19%). The majority of subjects (88.28%) had a good level of knowledge (knowledge score equal to 4, or more). The majority of participants (71%) agreed with the temporary traveling restrictions ban. The uptake of a future vaccine against SARS-CoV-2 was estimated at 43%. Knowledge score was significantly associated with both attitudes score (p = 0.011) and practices score (p < 0.001), indicating that subjects with a high knowledge score demonstrated a more positive perception on preventive measures and would practice more preventive measures. Attitudes score was significantly associated with practices score (p = 0.009) indicating that subjects with a higher attitudes score are more likely to perform practices towards the prevention of SARS-CoV-2 transmission. CONCLUSION: There is a high level of knowledge concerning SARS-CoV-2 pandemic among Greek health care workers and this is significantly associated with positive attitudes and practices towards preventive health measures. The high level of knowledge of health professionals about SARS-CoV-2 may have contributed considerably to the successful management of the pandemic in Greece. Tailored educational campaigns aiming to increase the proportion of health care workers willing to accept a potential SARS-CoV-2 vaccine could be of paramount importance in future proactive vaccine educational campaigns.
