The risk of reinfection is more latent than ever, given the spread of new SARS-CoV-2 (coronavirus) variants. Besides, it is a serious mistake to think that someone who got COVID-19 becomes totally immune to it and will not get it again, said Lely Solari, infectious disease specialist at the
National Health Institute (INS).
The INS expert explained that when there are many viruses in a person or community, they recombine genetically, undergo mutations and, thus, variants arise.
Solari stated that
the UK variant is transmitted more effectively, and that is reflected in a greater number of cases.
In addition to their high contagion rate, the Brazilian and South African variants may escape the immune response.
"This means that people who were previously infected and have developed antibodies are prone to experiencing a new bout of COVID-19, depending on the individual's predetermined factors. So, it would be a serious mistake to think that a person who had coronavirus will not get it again," she noted.
In this context, Solari stressed the need to responsibly comply with the health measures to prevent COVID-19 infection: using face masks properly, staying at home and going out only if strictly necessary, using a face shield when going to places with lots of people or poor ventilation, as well as washing hands constantly.
Types of face masks
Regarding the most recommended types of face masks to be used at this stage of the pandemic, the doctor said that the three-fold surgical masks provide more protection and should be used in open spaces.
