It is not because a person has already had covid-19 that they should relax in care. Quite the opposite. The chance of reinfection exists and the disease can manifest itself with much stronger symptoms a second time. The discovery was made by researchers from the Oswaldo Cruz Foundation (Fiocruz), Federal University of Rio de Janeiro (UFRJ) and D’Or Institute of Teaching and Research (Idor).

The study evaluated cases of reinfections in the state of Rio de Janeiro that showed that patients developed a more intense inflammatory body response and with more acute symptoms compared to the first infection.

According to the researchers, these reinfections were not linked to any variant of the coronavirus, overturning the belief that the second contagion only occurs because of new strains such as the Brazilian, the United Kingdom and South Africa.

The study – which will still be peer-reviewed – reinforces the need to maintain preventive measures against the new coronavirus, hand hygiene, social distance and the use of masks.
