COVID-19 in Patients With a Past History of Chemical War Injury: A Cross-Sectional Study in Southern Iran.

OBJECTIVE: This study aimed to determine whether COVID-19 is associated with a different presenting clinical picture or a more severe course of illness in people with a past history of chemical war injury. METHODS: This is a multicenter retrospective study in Fars Province, Iran, from August 22 to October 4, 2020. People with a past history of chemical war injury and COVID-19 were studied. Two age- and sex-matched control groups, double the size of the patient group each, from the same database of patients with COVID-19 who were hospitalized at the same time (ie, healthy controls and pseudocontrols). RESULTS: A total of 46 people with a past history of chemical war injury, 92 healthy controls, and 92 pseudocontrols were studied. People with COVID-19 and a past history of chemical war injury had a significantly higher rate of chest pain compared with others. There were no other clinical differences between the groups. Mortality rate was 17.39%, 15.21%, and 27.17% in people with a past history of chemical war injury, the control group, and the pseudocontrol group, respectively. CONCLUSIONS: A past history of a chemical war injury does not add to the risk of COVID-19 and does not significantly modify its clinical picture either.

Death Reporting in Breakthrough and Unvaccinated SARS-CoV-2 Infection Cases.

Vaccines are undeniably an important tool for controlling infectious disease outbreaks, and they are the most certain way to end the epidemic risk. This brief report describes the characteristics of coronavirus disease 2019 (COVID-19) deaths among breakthrough and unvaccinated cases hospitalized in Fars province in the south of Iran. This cross-sectional study was performed to compare breakthrough and unvaccinated death cases in Fars, Iran (February 2, to August 19, 2021). Among 444,728 fully vaccinated people, 60,800 breakthrough cases were detected. Thus, 501 died, of which 297 (297/501) cases were hospitalized and compared with the unvaccinated dead group. The median age for breakthrough and unvaccinated cases was estimated 79 and 65 y, respectively. All signs and symptoms of COVID-19 were more frequent in the unvaccinated group. Decreasing O2 saturation (less than 93%) happened more often in the unvaccinated group significantly. Unvaccinated dead patients had significantly shorter hospital stays. These patients received 66.63% Sinopharm, 0.67% Sputnik, 0.67% COVIran Barekat, and 31.99% AstraZeneca vaccines. None of them were health-care staff. Equitable access to safe and effective vaccines is critical to ending the COVID-19 pandemic. As vaccine uptake increases, we observed a decrease in mortality and protection from severe forms of the disease.

Entrepreneurial propensity for market analysis in the time of COVID-19: benefits from individual entrepreneurial orientation and opportunity confidence

This paper illustrates nascent entrepreneurs’ decision-making process during the COVID-19 pandemic and sheds light on determinants and mechanisms of entrepreneurial action. It examines the mediating role of opportunity confidence in the relation between the individual entrepreneurial orientation and the entrepreneurial propensity for market analysis (EPMA). Furthermore, it investigates the moderating role of entrepreneurship entry mode (opportunity vs. necessity) concerning our research model. Applying the theory of reasoned action (TRA), we could verify the mediating role of opportunity confidence. The findings also show that the impact of individual entrepreneurial orientation on EPMA and opportunity confidence is independent of entrepreneurial entry mode. In contrast, entrepreneurial entry mode can moderate the relation between opportunity confidence and EPMA. Results are discussed and research implications are provided.

COVID-19-associated facial cutaneous mucormycosis superinfection: A potentially life-threatening disease.

A 49-year-old male was involved in an accident and an abdominal computer tomographic examination revealed papillary renal cell carcinoma of the right kidney. During hospitalization, the patient was infected with COVID-19. In the following COVID-19 treatment, a black dot developed on the right side of the head and face. Antifungal therapy and surgical debridement were initiated and gradual improvement was observed.

Seroprevalence of SARS-CoV-2 antibody among urban Iranian population: findings from the second large population-based cross-sectional study.

BACKGROUND: The first large serosurvey in Iran found a SARS-CoV-2 antibody seroprevalence of 17.1% among the general population in the first wave of the epidemic by April, 2020. The purpose of the current study was to assess the seroprevalence of COVID-19 infection among Iranian general population after the third wave of the disease. METHODS: This population-based cross-sectional study was conducted on 7411 individuals aged ≥10 years old in 16 cities across 15 provinces in Iran between January and March, 2021. We randomly sampled individuals registered in the Iranian electronic health record system based on their national identification numbers and invited them by telephone to a healthcare center for data collection. Presence of SARS-CoV-2-specific IgG and IgM antibodies was assessed using the SARS-CoV-2 ELISA kits. The participants were also asked about their recent COVID-19-related symptoms, including cough, fever, chills, sore throat, headache, dyspnea, diarrhea, anosmia, conjunctivitis, weakness, myalgia, arthralgia, altered level of consciousness, and chest pain. The seroprevalence was estimated after adjustment for population weighting and test performance. RESULTS: The overall population-weighted seroprevalence adjusted for test performance was 34.2% (95% CI 31.0-37.3), with an estimated 7,667,874 (95% CI 6,950,412-8,362,915) infected individuals from the 16 cities. The seroprevalence varied between the cities, from the highest estimate in Tabriz (39.2% [95% CI 33.0-45.5]) to the lowest estimate in Kerman (16.0% [95% CI 10.7-21.4]). In the 16 cities studied, 50.9% of the seropositive individuals did not report a history of symptoms suggestive of COVID-19, implying an estimation of 3,902,948 (95% CI 3,537,760-4,256,724) asymptomatic infected individuals. CONCLUSIONS: Nearly one in three individuals were exposed to SARS-CoV-2 in the studied cities by March 2021. The seroprevalence increased about two-fold between April, 2020, and March, 2021.

Examining the relationship between strategic alliances and the performance of small entrepreneurial firms in telecommunications

An alliance is an effective strategy for knowledge-intensive businesses in competition. Yet, little is known about how strategic alliances work within small firms in the telecommunications industry, which plays an essential part in the COVID-19 pandemic infrastructure. The purpose of this article is to examine the impact of strategic alliance on firm performance among small entrepreneurial firms (SEFs) in the telecommunications industry. The study uses structural equation modeling to analyze primary data obtained from a sample of 74 small entrepreneurial firms in the telecommunications sector. We find that strategic alliances significantly and positively impact partners’ performance in terms of financial, operational, and organizational effectiveness among small entrepreneurial firms in the telecommunication sector. Drawing on the findings, we recommend small entrepreneurial firms pay particular attention to pre-alliance and post-alliance issues, including partner similarity, alliance experience, partner’ reputation, complementary skills, industry scope, commitment to improving trust and skill, and collaboration to boost performance. In addition, based on the results of this study, we discuss research implications for challenges of telecommunications SEFs in the time of the COVID-19 pandemic crisis.

Long COVID syndrome-associated brain fog.

We investigated the frequency of brain fog in a large cohort of patients with documented coronavirus disease-2019 (COVID-19) who have survived the illness. We also scrutinized the potential risk factors associated with the development of brain fog. Adult patients (18-55 years of age), who were referred to the healthcare facilities anywhere in Fars province from February 19, 2020 to November 20, 2020 were included. All patients had a confirmed COVID-19 diagnosis. In a phone call, at least 3 months after their discharge from the hospital, we obtained their current information. A questionnaire was specifically designed for data collection. In total, 2696 patients had the inclusion criteria; 1680 (62.3%) people reported long COVID syndrome (LCS). LCS-associated brain fog was reported by 194 (7.2%) patients. Female sex (odds ratio [OR]: 1.4), respiratory problems at the onset (OR: 1.9), and intensive care unit (ICU) admission (OR: 1.7) were significantly associated with reporting chronic post-COVID "brain fog" by the patients. In this large population-based study, we report that chronic post-COVID "brain fog" has significant associations with sex (female), respiratory symptoms at the onset, and the severity of the illness (ICU admission).

Liver Biomarkers Assay in COVID-19 Cases: A Comparison Study between Alive and Dead Patients.

BACKGROUND: Identifying effective biomarkers plays a critical role on screening; rapid diagnosis; proper managements and therapeutic options, which is helpful in preventing serious complications. The present study aimed to compare the liver laboratory tests between alive and dead hospitalized cases for prediction and proper management of the patients. METHODS: This retrospective, cross sectional study consists of all deceased patients admitted in one center in Shiraz, Iran during 19 Feb 2020 to 22 Aug 2021. For further comparison, we selected a 1:2 ratios alive group randomly. RESULTS: Overall, 875 hospitalized cases died due to COVID-19. We selected 1750 alive group randomly. The median age was significantly higher in died group (65.96 vs 51.20). Regarding the laboratory findings during the hospitalization ALT, AST, Bili.D were significantly higher in non-survivors than survivors but Albumin was less in deceased patients. It was revealed elevated levels of Albumin, AST, Bili.T and Bili.D were associated with increasing the risk of in hospital death. Moreover, the predictive effect of ALP and Bili.D had significantly more than others with high sensitivity and specify. CONCLUSION: We found patients with COVID-19 have reduced serum albumin level, and increase ALT and AST. The current results revealed abnormal liver chemistries is associated with poor outcome, which highlighted the importance of monitoring these patients more carefully and should be given more caution.

Risk Factors Associated with Long COVID Syndrome: A Retrospective Study.

Background: Recently, people have recognized the post-acute phase symptoms of the COVID-19. We investigated the long-term symptoms associated with COVID-19, (Long COVID Syndrome), and the risk factors associated with it. Methods: This was a retrospective observational study. All the consecutive adult patients referred to the healthcare facilities anywhere in Fars province from 19 February 2020 until 20 November 2020 were included. All the patients had a confirmed COVID-19 diagnosis. In a phone call to the patients, at least three months after their discharge from the hospital, we obtained their current information. The IBM SPSS Statistics (version 25.0) was used. Pearson Chi square, Fisher's exact test, t test, and binary logistic regression analysis model were employed. A P value of less than 0.05 was considered to be significant. Results: In total, 4,681 patients were studied, 2915 of whom (62.3%) reported symptoms. The most common symptoms of long COVID syndrome were fatigue, exercise intolerance, walking intolerance, muscle pain, and shortness of breath. Women were more likely to experience long-term COVID syndrome than men (Odds Ratio: 1,268; 95% Confidence Interval: 1,122-1,432; P=0.0001), which was significant. Presentation with respiratory problems at the onset of illness was also significantly associated with long COVID syndrome (Odds Ratio: 1.425; 95% Confidence Interval: 1.177-1.724; P=0.0001). A shorter length of hospital stay was inversely associated with long COVID syndrome (Odds Ratio: 0.953; 95% Confidence Interval: 0.941-0.965; P=0.0001). Conclusion: Long COVID syndrome is a frequent and disabling condition and has significant associations with sex (female), respiratory symptoms at the onset, and the severity of the illness.

Long COVID in children and adolescents.

BACKGROUND: To identify the prevalence and also the full spectrum of symptoms/complaints of children and adolescents who are suffering from long COVID. Furthermore, we investigated the risk factors of long COVID in children and adolescents. METHODS: All consecutive children and adolescents who were referred to the hospitals anywhere in Fars province, Iran, from 19 February 2020 until 20 November 2020 were included. All patients had a confirmed diagnosis of COVID-19. In a phone call to patients/parents, at least 3 months after their discharge from the hospital, we obtained their current status and information if their parents agreed to participate. RESULTS: In total, 58 children and adolescents fulfilled the inclusion criteria. Twenty-six (44·8%) children/adolescents reported symptoms/complaints of long COVID. These symptoms included fatigue in 12 (21%), shortness of breath in 7 (12%), exercise intolerance in 7 (12%), weakness in 6 (10%), and walking intolerance in 5 (9%) individuals. Older age, muscle pain on admission, and intensive care unit admission were significantly associated with long COVID. CONCLUSIONS: Long COVID is a frequent condition in children and adolescents. The scientific community should investigate and explore the pathophysiology of long COVID to ensure that these patients receive appropriate treatments for their condition.

A follow-up study of patients with COVID-19 presenting with seizures.

OBJECTIVE: We performed a follow-up study of patients with COVID-19 presenting with seizures. METHODS: All consecutive patients with seizures, who were referred to Namazee Hospital, Shiraz, Iran, with a diagnosis of COVID-19, from 10 August 2020 until 20 October 2020 were included in this longitudinal study. The clinical data were collected by the admitting physician. In a follow-up phone call to the discharged patients (after eight weeks or more), we inquired their seizure outcome. RESULTS: In total, 32 patients were studied; 28 patients were followed. Twelve patients (37.5%) presented with a single tonic-clonic seizure and nine (28.1%) had convulsive status epilepticus; one patient had functional (psychogenic) seizures. Ten patients (31.3%) had pre-existing epilepsy, eight others (25%) had pre-existing CNS problems (without epilepsy), one person (3.1%) had pre-existing functional seizures, and 13 individuals (40.1%) neither had epilepsy nor had other CNS problems. Eight patients (28.6%) reported experiencing seizure(s) after being discharged from the hospital; six of these had pre-existing epilepsy and one had pre-existing functional seizures. One patient, who had a newly developed ischemic brain infarction, reported experiencing recurrent seizures. CONCLUSION: Seizures in patients with COVID-19 are either acute symptomatic (in about two-thirds) or an exacerbation of a pre-existing epilepsy/functional seizures (in about one-third). A thorough investigation of the underlying etiology of seizures in patients with COVID-19 is necessary. Seizure outcome in patients, who are hospitalized with COVID-19 and seizures, is generally good.

The role of comorbidities on mortality of COVID-19 in patients with diabetes.

BACKGROUND: Patients with diabetes are one of the most high-risk group to become infected with SARS-CoV-2. Current study was designed to evaluate the risk of other complications in COVID-19 patients with diabetes. METHODS: In this cross-sectional study (25 February to July 10, 2020), 458 patients with diabetes were enrolled based on their characteristics, symptoms and signs, laboratory data and presence of other underlying diseases. Multiple logistic regression and Chi-square test analysis were used to check the effectiveness of other comorbidities on the mortality outcome among patients with diabetes. RESULTS: Of 458 patients with diabetes, 306 (67%) had other underlying diseases, such as 200 (65.4%) hypertension, 103 (33.7%) cardiovascular diseases and 29 (9.5%) kidney diseases. The rate of fatality was significantly high in patients with chronic kidney and liver diseases. The odds of mortality were increased 3.1-fold for patients over 55 years as compared to those under 55 years (P = 0.011), and the odds of mortality outcome were more than 5.1-fold for those who had chronic kidney disease (P < 0.001). CONCLUSIONS: The presentation of SARS-CoV-2 in older patients with diabetes with other comorbidities such as chronic kidney and liver diseases is more severe in risk of mortality.

COVID‐19 presentations and outcome in patients with epilepsy

ObjectiveTo determine whether patients with epilepsy (PWE) are particularly over‐represented in a very large cohort of patients with COVID‐19. We also investigated whether COVID‐19 is associated with a different clinical picture or a more severe course of illness in PWE (compared with others).MethodsAll consecutive patients who referred to and admitted at healthcare facilities anywhere in Fars province (located in the south of Iran with a population of 4,851,000 people) from February 19, 2020 until November 20, 2020 were included.ResultsA total of 37,968 patients were studied. Eighty‐two patients (0.2%) had pre‐existing epilepsy. Seizures were significantly more frequent among PWE as a presenting manifestation of COVID‐19 compared with that in people without epilepsy (Odds Ratio = 27;p = 0.0001). Furthermore, PWE less often reported cough (significantly) and more often had gastrointestinal symptoms (vomiting and anorexia;as trends) compared with those in people without epilepsy. Patients with epilepsy were not differently likely to be intubated or admitted at ICUs. Case fatality rates were not different between the two groups [9.8% in PWE and 8.5% in people without epilepsy;p = 0.690].ConclusionPatients with epilepsy are not susceptible to contracting COVID‐19 more than other individuals. Furthermore, COVID‐19 in PWE is not associated with a more severe illness or a poorer prognosis. However, PWE and COVID‐19 may present somewhat differently than others with such an illness. Why PWE less often present with cough and more often present with gastrointestinal symptoms is not clear yet and should be investigated and clarified in the future studies.

Designing a Multicenter Registry of COVID-19 and Other Respiratory Infections in Fars, Iran.

OBJECTIVE: A year after the emergence of a novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as a new crisis in respiratory infections, there remain many uncertainties and unknowns about SARS-CoV-2 and the disease it causes, called coronavirus disease (COVID-19). Although COVID-19 is known as a respiratory disease, some atypical manifestations have been seen, different from those seen in other types of viral respiratory infections. This paper aims to describe designing, launching, and implementing a data collection system for all respiratory diseases, with a focus on SARS-CoV-2 from the onset of this pandemic. METHOD: The current registry is designed in compliance with the standard Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines, along with the declaration of Helsinki principles. RESULTS: A respiratory disease registry, with an emphasis on COVID-19 and other co-infections, was developed. Data consisted of demographic, clinical, and supporting information about SARS-CoV-2 and other respiratory viral diseases. CONCLUSION: It is hoped that the current data registry will facilitate patient evaluation and improve the outcomes of cases of respiratory infection defined by a particular condition, disease, or exposure. Moreover, the registry can harmonize data about the treatment, outcomes, and well-being of patients who receive care over time, and identify best practices.

COVID-19 in patients with Down syndrome.

PURPOSE: The aim of the current study was to determine whether COVID-19 is associated with a different presenting clinical picture or a more severe course of illness in people with Down syndrome (DS). METHODS: All consecutive patients who were admitted at healthcare facilities anywhere in Fars province (located in the south of Iran with a population of 4,851,000 people) from 19 February 2020 to 20 November 2020 were included. For every patient with DS, three age- and sex-matched patients with COVID-19 and without any underlying medical conditions were selected as controls. RESULTS: During the study period, 37,968 patients were hospitalized with a diagnosis of COVID-19. Eighteen patients had DS. Patients with DS were significantly more likely to be intubated [7 patients (39%)] compared with those without DS [3 patients (6%)]; p = 0.002. Patients with DS significantly more often died of COVID-19 compared with the controls [8 (44.4%) vs. 1 (1.9%); odds ratio: 24.37; 95% confidence interval 2.39-247.94; p = 0.007]. CONCLUSION: Patients with DS are among the high-risk populations with respect to severe COVID-19 and should receive the vaccine as soon as possible. Furthermore, they should receive more intensive care if they get hospitalized with the illness.

Management of colon and rectal cancers during COVID-19 pandemic: A clinical guideline (TUMS-CRC-CoV19 Guideline).

Background: In a resource-demanding COVID-19 pandemic, guidelines can free up health care resources needed for providing better care to those with COVID-19 and other patients. This study was performed to design a guideline to manage patients with colorectal cancers during the COVID-19pandemic. Methods: To design this guideline, major topics and headings of colon and rectal cancers (CRC) were selected and included. Based on the extent of COVID-19 infection in the community and availability of hospital resources, the guideline has been designed for 2 major COVID-19 phases. Several multidisciplinary discussion sessions were held to review the comments of experts, finalize the data, and write the guideline. Results: This guideline has been prepared in 2 main COVID-19 phases of the community/hospital. Phase A refers to the condition where a large number of COVID-19 patients are admitted to the hospital, but limited surgical ICU beds and facilities are still accessible. In phase B, many people are affected by COVID-19, and all hospital resources are allocated for COVID 19 patients. In phase A, 4 major groups are discussed, including malignant and suspicious colorectal polyps, colon cancers, rectal cancers, and recurrent cancers. The approach to emergent cases, including obstruction, bleeding, and perforation, will be presented in phase B. Conclusion: This guideline is a comprehensive instruction on the approach to colorectal cancers during the COVID-19 pandemic that covers the major topics of colon and rectal cancers in detail.

SARS-CoV-2 antibody seroprevalence in the general population and high-risk occupational groups across 18 cities in Iran: a population-based cross-sectional study.

BACKGROUND: Rapid increases in cases of COVID-19 were observed in multiple cities in Iran towards the start of the pandemic. However, the true infection rate remains unknown. We aimed to assess the seroprevalence of antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 18 cities of Iran as an indicator of the infection rate. METHODS: In this population-based cross-sectional study, we randomly selected and invited study participants from the general population (from lists of people registered with the Iranian electronic health record system or health-care centres) and a high-risk population of individuals likely to have close social contact with SARS-CoV-2-infected individuals through their occupation (from employee lists provided by relevant agencies or companies, such as supermarket chains) across 18 cities in 17 Iranian provinces. Participants were asked questions on their demographic characteristics, medical history, recent COVID-19-related symptoms, and COVID-19-related exposures. Iran Food and Drug Administration-approved Pishtaz Teb SARS-CoV-2 ELISA kits were used to detect SARS-CoV-2-specific IgG and IgM antibodies in blood samples from participants. Seroprevalence was estimated on the basis of ELISA test results and adjusted for population weighting (by age, sex, and city population size) and test performance (according to our independent validation of sensitivity and specificity). FINDINGS: From 9181 individuals who were initially contacted between April 17 and June 2, 2020, 243 individuals refused to provide blood samples and 36 did not provide demographic information and were excluded from the analysis. Among the 8902 individuals included in the analysis, 5372 had occupations with a high risk of exposure to SARS-CoV-2 and 3530 were recruited from the general population. The overall population weight-adjusted and test performance-adjusted prevalence of antibody seropositivity in the general population was 17·1% (95% CI 14·6-19·5), implying that 4 265 542 (95% CI 3 659 043-4 887 078) individuals from the 18 cities included were infected by the end of April, 2020. The adjusted seroprevalence of SARS-CoV-2-specific antibodies varied greatly by city, with the highest estimates found in Rasht (72·6% [53·9-92·8]) and Qom (58·5% [37·2-83·9]). The overall population weight-adjusted and test performance-adjusted seroprevalence in the high-risk population was 20·0% (18·5-21·7) and showed little variation between the occupations included. INTERPRETATIONS: Seroprevalence is likely to be much higher than the reported prevalence of COVID-19 based on confirmed COVID-19 cases in Iran. Despite high seroprevalence in a few cities, a large proportion of the population is still uninfected. The potential shortcomings of current public health policies should therefore be identified to prevent future epidemic waves in Iran. FUNDING: Iranian Ministry of Health and Medical Education.

Cutaneous Vesicular of COVID-19 in Two Burn Patients.

Despite the whole world's effort for controlling an ongoing global outbreak caused by new corona virus; it is still a major public health issue. Any hospitalized patient or outpatient in burn departments should be considered as a potential infectious source of COVID-19, which may cause an overwhelming of disease. However, there are no previous experiences about COVID-19 in burn patients all over the world, and here we reported two burn cases at Amir-al-Momenin Burn Hospital Affiliated to Shiraz University of Medical Sciences, Shiraz, Iran with skin manifestations, which were detected as a rarely COVID-19 symptom. A 13-year-old girl [total body surface area (TBSA): 18%] and a 37-year-old woman (TBSA: 30%) who had burn injuries by gas explosion and car accident, respectively were enrolled. After admission, some vesicular injuries were visible in burn area. To confirm, skin biopsy specimens were either sent for histopathology examination or for real time polymerase chain reaction (PCR) as follow: Herpes Simplex Virus (HSV), chicken pox, and potassium hydroxide (KOH) for fungal infections. All test results were negative. Although they had no symptoms of COVID-19, two swabs from nasopharyngeal and oropharyngeal samplings were taken, the result was negative either. Specimens were obtained from vesicular lesions for qRT-PCR assay of COVID-19. According to the molecular results for vesicular samples, all the results were positive for COVID-19. Unlike all other COVID-19 patients who have respiratory symptoms, SARS-COV-2 appeared by cutaneous vesicular and blisters in two burn cases.

Prevalence of underlying diseases in died cases of COVID-19: A systematic review and meta-analysis.

INTRODUCTION: Underlying disease have a critical role in vulnerability of populations for a greater morbidity and mortality when they suffer from COVID-19. The aim of current study is evaluating the prevalence of underlying disease in died people with COVID-19. METHODS: The current study have been conducted according to PRISMA guideline. International database including PubMed, Scopus, Web of Science, Cochrane and google scholar were searched for relevant studies up to 1 June. All relevant articles that reported underlying disease in died cases of COVID-19 were included in the analysis. RESULTS: After screening and excluding duplicated and irrelevant studies, 32 articles included in the analysis. The most prevalent comorbidities were hypertension, diabetes, cardiovascular disease, liver disease, lung disease, malignancy, cerebrovascular disease, COPD and asthma. Among all reported underlying disease, highest and lowest prevalence was related to hypertension and asthma which were estimated 46% (37% - 55%) and 3% (2%- 6%), respectively. CONCLUSION: In summary, underlying disease have a critical role in poor outcomes, severity of disease and high mortality rate of COVID-19 cases. Patients with hypertension, cardiovascular disease and diabetes should be carefully monitored and be aware of health protocols.
