A study carried out by researchers from the universities of São Paulo (USP), Leeds (United Kingdom) and Harvard (United States) suggests that indicators of pollution and mobility can also be used to predict the increase in the number of cases and deaths from COVID-19. In an article published on the medRxiv platform, still without peer review, the authors report that even slight reductions in the rates of mobility and pollution observed in the city of São Paulo were reflected in a [...]

A study conducted at USP (University of São Paulo) reveals that the incidence of infection by new coronavirus among athletes from the São Paulo Football Federation during the 2020 season it was 11.7% – an index equivalent to that of health professionals who work at the forefront of combating the pandemic. To reach this number, the authors retrospectively analyzed almost 30 thousand RT-PCR tests applied to 4,269 athletes over eight tournaments, six of which were [...]

A regular practice of physical activity it is already more than established as an effective way to guarantee quality of life and reduce mortality. A recent study published in the journal “JAMA Internal Medicine”Showed, however, that not only regularity, but also the intensity of physical activity, result in greater longevity. The conclusion is from a study based on data from 403,681 people, in which the reduction in mortality associated with different combinations of [...]

Two studies recently released on the platform medRxiv, still without peer review, show how the delay in vaccination against COVID-19 in Brazil can compromise the efficiency of the campaign in terms of reducing the number of deaths from the disease at the current epidemic peak. In one of articles, whose main author is a professor at the Faculty of Medicine of the University of São Paulo (FM-USP) Eduardo Massad, it is estimated that about 127 thousand lives would be saved by the end of [...]

Laboratory experiments conducted at the State University of Campinas (Unicamp) indicate that antibodies present in the blood plasma of people who have already had covid-19 and recovered are about six times less efficient to neutralize the Brazilian variant of SARS-CoV-2, called P.1., than the so-called strain B, which circulated in the country in the first months of the pandemic. The study also shows that the plasma collected from individuals who received the second dose of CoronaVac about [...]

Laboratory experiments conducted at the State University of Campinas (Unicamp) indicate that antibodies present in the blood plasma of people who have had COVID-19 and recovered are about six times less efficient in neutralizing the Brazilian variant of SARS-CoV-2, called P .1., Than the so-called lineage B, which circulated in the country in the first months of the pandemic. The study also shows that the plasma collected from individuals who received the second dose of CoronaVac about five [...]

The Brazilian variant of the coronavirus, first detected in Manaus (Amazonas), may have the ability to circumvent the antibodies acquired by those who have already had covid-19 and cause a new infection. This is what a study, which has not yet been revised, detailed by the The New York Times this Monday (1st). Named P.1, the variant of Sars-CoV-2 was identified in December in the Amazonian capital, but it may have appeared a month earlier and facilitated transmission in the city, which [...]

The Brazilian variant of the coronavirus, which probably emerged in Manaus at the end of 2020, may circumvent the immune system of individuals already infected with Covid-19 and cause a new infection, according to a new survey released on Monday (1st). Furthermore, can be up to 2.2 times more transmissible than other variants of the virus. “This new variant can infect even those who already have antibodies against the new coronavirus after a first natural infection” – Ester [...]

The Brazilian variant of the new coronavirus – known as P.1. or variant of Manaus – probably emerged in the Amazonian capital in mid-November 2020, about a month before the number of hospitalizations for severe acute respiratory syndrome in the city made a leap. In just seven weeks, P.1. became the most prevalent strain of Sars-CoV-2 in the region, report researchers from the Brazil-United Kingdom Center for Discovery, Diagnosis, Genomics and Epidemiology of Arbovirus (CADDE), in an [...]
