Scientists have found out who is at risk of re-contracting COVID-19 and when

Scientists from the United States conducted a large-scale study of patients in whom PCR re-showed the presence of SARS-CoV-2. The results are published on the medRxiv.org preprint server.

American researchers have conducted a detailed analysis of cases of re-infection with a new type of coronavirus. It is noted that the scientists worked in compliance with the recommendations of the US Centers for Disease Control (CDC). The authors selected patients from the US Electronic Health Records (EHR) database who had positive PCR test results. In addition, they showed clear symptoms of COVID-19.

The average age of all re-infected with the new type of coronavirus was 64.5 years. In addition, most of the patients smoked and were obese. They also had immune disorders, hypertension and diabetes.

The authors of the study emphasize that in all cases, the patients were indeed reinfected. Genomic analysis showed that the patients had no latent course of the initial variant of the disease. It is noted that the interval between the first and second infection averaged 101 days.

In conclusion, the scientists noted that approximately 70% of those infected were hospitalized both times. The authors of the study conclude that re-infection is no easier than the first.
