How often can you get sick with coronavirus

Scientists have determined the approximate frequency of re-infection with coronavirus and told what factors increase the risk of meeting with it regularly.

According to The Guardian, the study was carried out by Danish scientists and specialists from the Yale University School of Medicine (USA), using available data on infections and incidence from the beginning of the pandemic to September this year. The main conclusion is that those who refuse to be vaccinated against COVID-19 get sick again much more often than those vaccinated.

In particular, the results of the study indicate that unvaccinated people run the risk of meeting with coronavirus every year and a half, with all the consequences that follow from this meeting. And if in 2020 re-infection with covid was considered, rather, an exception, now it has become clear that immunity to it weakens over time and a person can become infected again.

Elderly people are especially susceptible to re-infection: patients over 65 years of age are protected from re-infection by only 47%, while younger ones – by 80% within 6 months.

Interestingly, the model built by the Yale University School of Medicine experts, based on the available data for the period of the pandemic, shows that if there were no vaccinations and government-imposed measures against COVID-19, people could become infected every 3 months.

The situation with re-infection is also influenced by the emergence of new strains of coronavirus. For example, in the UK, 296 cases of infection were detected for the second time among 20,000 residents who tested positive from July last year to September this year. Upon re-infection, the interval between infections was approximately six months.
