It is possible to catch Covid again 20 days after the test is positive

Earlier this year, the Ômicron variant caused the fourth wave of Covid-19 in Espírito Santo, which has the highest moving average of confirmed cases of the disease since the onset of the pandemic. Now, the state is once again experiencing an increase in records of infection. This time, it is due to a submutant of Sars-Cov-2. Viral changes that further transmit the virus in relation to the unvaccinated group may be behind this new phenomenon in the pandemic. If you are re-infected within a month.

As reported by O Globo, studies conducted in Denmark include Ômicron and its subvariants. Reinfection can occur in just 20 days.. Researchers reached this conclusion after analyzing more than 1.8 million people infected during the high circulation period of strains in Europe from November 2021 to February 2022. Not vaccinated for 30 years.

Infectious scientist Lauro Ferreira Pinto states that reinfection at intervals of less than 30 days is not common, but the currently approved immune agent is the first strain of Sars-Cov-. Given that it was developed when it was still present, there are signs of vaccine leakage circulation. 2. Not to mention those who did not complete the vaccination schedule or even received the first dose.

“There are many subvariants to Omicron. Currently circulating are B4 and B5. One of the features is that they can be re-infected with Omicron. Less than a month is rare, but they were infected in January. One can have it again in February, and it’s vaccine avoidance, yes. The vaccine protects against serious cases, but not against new infections. You have a milder infection. Vaccination will continue to be the best way to prevent serious cases, “he emphasizes.

Epidemiologist Ethel Maciel, a professor at the Federal University of Espirito Santo (Ufes), recalls that at the beginning of the pandemic, he was infected with Sars-Cov-2 without mutation and then discovered a mutant. This photo was repeated, and the person who was first contaminated with the strain always re-infected another variant and passed through alpha, beta, gamma, and delta at an even faster pace. Now, what happens is that subtype of Omicron.

“Previously, the intervals were three or four months. Now they are much shorter, days or weeks. This is due to mutations that allow the virus to escape further. Again, this raises concerns about the increase in infections we are experiencing now that Brazil is in an emergency again and has a long Covid, “he points out.

Luis Carlos Lebrin, Under Secretary of Health Surveillance, defends that these episodes of reinfection provide at least the protection required by the Sars-Cov-2 contract and are commonly referred to as herd immunity. Emphasize that it helps to completely overturn people’s theory. “But the virus doesn’t respect the previous immunity of the disease itself,” he points out.

Three experts claim that vaccines prevent the most serious cases that can lead to death. “The higher the vaccination rate, the higher the degree of protection,” Reblin concludes.
