COVID-19 (coronavirus disease 2019), a disease caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection, may have a more or less severe course. The aim of this study was to analyse the symptoms which occurred in a group of people who tested positively for the presence of the genetic material of the virus

Material and methods:
The analysis was based on the results of 337 questionnaires collected from Polish patients – 185 (55%) females and 152 (45%) males aged 18–86. The questionnaire included 26 questions, of which 11 were related to systemic symptoms. The frequency of their occurrence and their severity were determined according to Visual Analogue Scale (VAS).

The most common symptoms that occurred in over 50% of the respondents included: general weakness (91% of the respondents, severity of 6.25 on VAS), musculoskeletal pain (77%, VAS 5.67), headache (65%, VAS 5.37) and cough (56%, VAS 4.76). Runny nose, fever above 38℃ and sore throat were less common and occurred in 39% of the subjects. The least frequent symptoms were diarrhoea (23%), skin lesions (7%) and vomiting (3%). When determining the correlation coefficient, it was also found that dyspnoea occurred most often with general weakness (r = 1), whereas general weakness was less frequently associated with musculoskeletal pain (r = 0.8). No statistically significant relationships were found between the frequency of the symptoms and age, gender or the presence of comorbidities in the respondents.

The observations showed that in the analysed group of people with SARS-CoV-2 infection, the disease had a mild-to-moderate course. General weakness, musculoskeletal pain, cough, and upper respiratory tract infection symptoms were the most common.
