RISK FACTORS FOR SEVERE AND CRITICAL PATIENTS WITH COVID-19

The viability of SARS-CoV-2 at environmental facilities is maintained for up to 3 days. The transmission coefficient, i.e. the average number of people who are sure to get infected from one infected person in a population that has never encountered a particular disease before, is 1.5-2.5. The transmission routes of SARS-CoV-2 are airborne, contact and possibly fecal-oral. COVID-19 disease is caused by a new virus, so people of all age categories are susceptible to infection. The analysis conducted by the Chinese Center for Disease Control and Prevention showed that among 72,314 cases, 87% were aged 30 to 79 years, children 9 years and younger 1%, children and adolescents aged 10 to 19 years 1%, elderly people aged 80 years 3%. Cases of children's disease were more often reported in the family or as a result of contact with an infected person.
