Description of intervention(s) / exposure
The cross-sectional observation study will be carried out on physicians and nurses (n=80) from the Wroclaw hospitals (Poland). The study has a voluntary charter and requires informed and written consent to participate.

Two study groups will be identified. The first group (n=40) will include health care providers (physicians and nurses), who have so far had a negative result test of the real-time polymerase chain reaction (rt-PCR) for SARS-CoV-2 (control group). The second group (n=40) will include physicians and nurses who have undergone a COVID-19 infection with a confirmed rt-PCR test for SARS-CoV-2.

On the day of the examination, 1 sample of blood (2.7 ml) will be taken to determine the ATII-1R concentration. After collection, blood samples will be left at room temperature to form a clot (about 30 minutes). They will then be centrifuged for 10 min with 3000 rpm. The resulting sera will be frozen and stored at -700C until the determination is performed.

Demographic data, BMI, blood group, ATII-1R concentration will be analyzed. Additionally, information on chronic diseases (diabetes, hypertension, nicotinism, kidney failure) and medications will be collected. The results will be analyzed statistically.

In the group of "recoveries", the symptoms of SARS-CoV-2 infection and the severity of COVID-19 will be additionally evaluated according to the illness categories described in Clinical Presentation of People with SARS-CoV-2 Infection based on the COVID-19 Treatment Guidelines developed by the National Institutes of Health (NIH):
1. Asymptomatic or Presymptomatic Infection: Individuals who test positive for SARS-CoV-2 using a virologic test (i.e., a nucleic acid amplification test or an antigen test) but who have no symptoms that are consistent with COVID-19.
2. Mild Illness: Individuals who have any of the various signs and symptoms of COVID-19 (e.g., fever, cough, sore throat, malaise, headache, muscle pain, nausea, vomiting, diarrhea, loss of taste and smell) but who do not have shortness of breath, dyspnea, or abnormal chest imaging.
3. Moderate Illness: Individuals who show lower respiratory disease evidence during clinical assessment or imaging and who have a saturation of oxygen (SpO2) equal to 94% on room air at sea level.
4. Severe Illness: Individuals who have SpO2 less than 94% on room air at sea level, a ratio of the arterial partial pressure of oxygen to fraction of inspired oxygen (PaO2/FiO2) less than 300 mmHg, respiratory frequency more than 30 breaths per minute or lung infiltrates more than 50%.
5. Critical Illness: Individuals who have respiratory failure, septic shock, and/or multiple organ dysfunction

The approximate duration of the cross-sectional assessment would be 60-90 minutes.

Statistical methods / analysis
Continuously distributed data will be tested for normality using the Shapiro-Wilk and Kolmogorov-Smirnov tests. The critical significance level was assumed at p<0.05. The significance of the differences in the mean values between two groups (e.g., baseline level – 2h level) for the parameters of normal distribution and homogeneous variances will be checked with the t-Student test for the related variables. The significance of differences in average values (medians) between two groups for parameters with a distribution considerably deviating from the theoretical normal distribution or heterogeneous variances will be verified with the Wilcoxon test. The hypotheses about the absence of differences in mean values in more than two groups will be verified using variance analysis (ANOVA). The hypotheses about the absence of differences in average values (medians) in more than two groups were verified using the Kruskal-Wallis and Friedman tests. A receiver operating characteristic (ROC) curve analysis will be performed to calculate the area under the ROC curve. The best cut-off values will be calculated to maximize the sum of sensitivity and specificity. The positive predictive value (PPV), negative predictive value (NPV), and accuracy will also be calculated. The results will be considered statistically significant when the p-values were lower than 0.05. Analyses will be performed using Statistica v.10 (StatSoft, Inc, Tulsa, USA).

Summary
Brief summary
The aim of this study is to determine the correlation of angiotensin II type 1 receptor (ATII-1R) with the incidence and severity of Coronavirus Disease 2019 (COVID-19) among medical personnel.

This is a cross-sectional and observational trial among medical personnel who works in their clinical practice with COVID-19 patients.

The planned study determines the correlation between the ATII-1R receptor concentration in health care professionals working with COVID-19 patients and the risk and hardness of severe acute respiratory coronavirus type 2 syndrome (SARS-CoV-2) infection.

The following research hypotheses were elaborated:
1. A high ATII-1R receptor concentration correlates with an increased incidence of COVID-19.
2. A high ATII-1R receptor concentration correlates with increased severity of COVID-19.
3. Male patients have a higher incidence of COVID-19.

The study will involve 80 physicians and nurses who meet specific eligibility criteria. These will be medical staff from Wroclaw hospitals (Poland). The study has a voluntary charter.

Two study groups will be identified. The first group will include health care providers (physicians and nurses), who have so far had a negative result test of the real-time polymerase chain reaction (rt-PCR) for SARS-CoV-2 (control group). The second group will include physicians and nurses who have undergone a COVID-19 infection with a confirmed rt-PCR test for SARS-CoV-2.

On the day of the examination, 1 sample of blood (2.7 ml) will be taken to determine the ATII-1R concentration. After collection, blood samples will be left at room temperature to form a clot (about 30 minutes). They will then be centrifuged for 10 min with 3000 rpm. The resulting sera will be frozen and stored at -700C until the determination is performed.

Additionally, demographic data, BMI, blood group, and the presence of co-morbidities and actual medications will be studied. The results will be analyzed statistically.
