Perceived COVID-19 Severity, Risk of Infection, and Prevention Self-Efficacy in Saudi Arabia During Lockdown: A Population-Based National Study.

Evidence shows that the risk perception of humans can significantly affect their response to a threat. This population-based, cross-sectional study explored the determinants of perceived disease seriousness, perceived disease infectiveness, and perceived prevention self-efficacy of coronavirus disease (COVID-19), during the lockdown period, using the health belief model for preventive behavior (HBMPB) among 4423 adults in Saudi Arabia from 13 provinces. Multivariate binary regression was used to analyze the independent factors of three risk perception variables and to measure their effect on adherence to preventive measures. Overall, COVID-19 seriousness was perceived to be higher than that of diabetes and lower than that of a heart attack, while its infectiousness was perceived to be high by 75.3% of the participants. Furthermore, 66.6% had a low perception of their prevention self-efficacy. The HBMPB showed independent effects of all three risk perception parameters on adherence to the preventive measures, including perceived seriousness (Odd's ratio [OR] = 1.26; 95% confidence interval [95% CI] = 1.01-1.56), infectiousness (OR = 1.90; 95% CI = 1.52-2.38), and prevention self-efficacy (OR = 1.51; 95% CI = 1.20-1.91). Authorities should maintain an optimal level of communication on the COVID-19 risk, communicate more about the virus' cycle and the disease to demystify the rationale of the preventive measures, and enhance confidence in their efficiency.

Monkeypox caused less worry than COVID-19 among the general population during the first month of the WHO Monkeypox alert: Experience from Saudi Arabia.

BACKGROUND: Monkeypox re-emerged in May 2022 as another global health threat. This study assessed the public's perception, worries, and vaccine acceptance for Monkeypox and COVID-19 during the first month of WHO announcement. METHODS: A large-scale, cross-sectional survey was conducted between May 27 and June 5, 2022, in Saudi Arabia. Data were collected on sociodemographic characteristics, previous infection with COVID-19, worry levels regarding Monkeypox compared to COVID-19, awareness, and perceptions of Monkeypox, and vaccine acceptance. RESULTS: Among the 1546 participants, most respondents (62%) were more worried about COVID-19 than Monkeypox. Respondents aged 45 years and above and those with a university degree or higher had lower odds of agreement with Monkeypox vaccination (OR 0.871, p-value 0.006, OR 0.719, p-value <0.001), respectively. Respondents with moderate to a high level of self and family commitment to infection control precautionary measures and those who expressed self and family worry of Monkeypox infection had significantly higher odds of vaccination agreement (OR 1.089 p-value = 0.047, OR1.395 p-value = 0.003) respectively. On the other hand, respondents who previously developed COVID-19 were significantly more worried about the Monkeypox disease (1.30 times more, p-value = 0.020). CONCLUSION: Worry levels amongst the public are higher from COVID-19 than Monkeypox. Perception of Monkeypox as a dangerous and virulent disease, worry from contracting the disease, and high commitment to infection precautionary measures were predictors of agreement with Monkeypox vaccination. While advanced age and high education level are predictors of low agreement with vaccination.

In-vitro activity of ceftolozane/tazobactam against recent clinical bacterial isolates from two Saudi Arabian hospitals.

BACKGROUND: Antimicrobial resistance is continuously increasing. Adding tazobactam to ceftolozane improves the latter's activity spectrum against resistant strains. We aimed to determine the susceptibility of recently collected bacterial isolates to ceftolozane/tazobactam (C/T) and other antibiotics. METHODS: This was a prospective cohort study conducted between March 2017 and March 2018. The in-vitro activities of C/T and 14 other antibiotics were assessed against 192 gram-negative bacterial (GNB) isolates (P. aeruginosa, K. pneumonia, E. coli, and other Enterobacterales) prospectively collected from two hospitals in Saudi arabia; in the laboratories of the International Health Management Associates Inc. Samples were obtained from intensive care units (ICUs) and non-ICU locations. The minimum inhibitory concentrations (MICs) of the antibiotics were determined by broth microdilution. Isolates were obtained from different infection sites [urine (31.8%), urinary bladder samples (15.1%), abscess/pus (20.3%), endotracheal aspirates (18.8%)]. RESULTS: Our sample showed substantial drug resistance; 66.1% of the collected isolates showed either multiple or extensive drug resistance. Susceptibility rates of P. aeruginosa (n = 50), E.coli (n = 40), K. pneumoniae (n = 64) and other Enterobacterales (n = 38) to C/T were 74%, 87.5%, 48.4% and 71.1%, respectively. According to MIC50 values (1 µg/mL for both P. aeruginosa and other Enterobacterales, 0.5 µg/mL for E.coli, and 4 µg/mL for K. pneumoniae), C/T was among the most potent antibiotics against these isolates. CONCLUSIONS: C/T displayed high potency against all examined bacterial isolates. It was mainly active against E.coli followed by P.aeruginosa and other Enterobacterales and its lowest susceptibility rate was reported against K. pneumoniae.

Duration of viable SARS-CoV-2 shedding from respiratory tract in different human hosts and its impact on isolation discontinuation polices revision; a narrative review.

BACKGROUND: The duration of viable viral shedding is important to be defined in regards of viral transmission in SARS-CoV-2 infection with the backdrop of the current worldwide effort for revising isolation polices and establishing the duration of infectiousness. METHODS: In this review we searched databases including Medline and google scholar for research articles published between January 2020 and January 2022. We included case reports, case series, cross sectional, cohort, and randomized control trials that reported the duration of shedding of viable SARS-CoV-2 virus. After evaluating the criteria for inclusion, 32 articles (2721 patients) were included. RESULT: This review showed that the median for the last day of successful viral isolation was 11 (8.5-14.5 95% CI) , 20 (9.0-57.5 95 %CI), 20 (9.0-103 95 %CI) for the general population, critical patients and immunocompromised individuals, respectively, with significant association between prolonged viral shedding, disease severity (P-Value 0.024) and immunosuppressive status (P-Value 0.023).The corresponding higher cutoff of CTv to culturable virus ranged between 26.25 and 34.00 (95% confidence interval) with median of 30.5, and higher values were observed when critical (25.0-37.37 95 %CI) and immunocompromised patients (20.0-37.82 95 %CI) have been excluded, this deviation did not represent a statistical significance (P-Value 0.997 and 0.888) respectively. CONCLUSION: Our review highlights that repeating SARS-CoV-2 viral RNA test solely in recovering patients has no importance in determining infectivity and emphasizes the individualization of de-isolation decisions based on the host factors and a combined symptom and testing-based approaches with the later benefiting most of correlation with recently introduced rapid antigen test. Our finding in the review also opposes the most recent CDC Guidance on shortening isolation duration in term of the last days of viable transmissible virus, therefore caution should be considered when revising such protocols.

Knowledge and attitudes toward HIV/AIDS among the general population of Jeddah, Saudi Arabia.

BACKGROUND: In contrast to most regions of the world where a decline of the HIV epidemic can be seen, data from the Middle East and North Africa (MENA) region suggests increasing incidence among key populations in the region. Accurate data collection has long been limited by social, cultural, and religious taboos. Understanding knowledge levels and attitudes toward HIV/AIDS is an important component to design adequate and culturally appropriate awareness and prevention programs. METHODS: A survey was conducted including 3841 participants during a series of public HIV/AIDS awareness campaigns from 2013 to 2015 in Jeddah, Saudi Arabia. Participants completed a questionnaire including socio-demographic data, and questions around knowledge and attitudes toward HIV/AIDS. A knowledge score was created. Frequencies were calculated for all variables, mean knowledge scores were compared using non-parametric tests. Categorical variables were compared using Chi-squared test. The mean knowledge score was 5.2 out of 9 possible points. Respondents in the age class 19-25, respondents with university degrees, and those who know people living with HIV/AIDS had higher scores. Overall the attitude toward people living with HIV/AIDS was negative, more than 40% suggested that HIV positive people should be isolated and less than 20% would support a marriage with an HIV positive person. Negative attitudes were more common among people in older age groups, with a lower educational background, and respondents that did not know anyone living with HIV/AIDS. CONCLUSION: Knowledge gaps and negative attitudes of the general public toward people living with HIV/AIDS have been identified and can be used to tailor educational campaigns in Saudi Arabia.

Fatal hemophagocytic syndrome as a manifestation of immune reconstitution syndrome in a patient with acquired immunodeficiency syndrome.

Hemophagocytic lymphohistiocytosis (HLH) is an aggressive and potentially life-threatening condition characterized by uncontrolled hyper inflammation caused by various inherited or acquired immune deficiencies. We report a case of a 42-year-old man, newly diagnosed with HIV on the basis of a low CD4 T lymphocyte count (17/mm³) and HIV viral load >100,000 copies/mL by polymerase chain reaction tests who was undergoing an anti-retroviral regimen (emitricitabine, tenofovir disoproxil fumarate, ritonavir, and darunavir) and opportunistic infection prophylaxis (clarithromycin and atovaquone). He was concomitantly diagnosed with hemophagocytic syndrome, also known as HLH. He developed increasingly severe pancytopenia while on treatment with anti-retroviral drugs.
