The patient, who was not identified, is a health professional, who in March presented mild symptoms associated with covid-19.
A Brazilian patient carried the Sars-CoV-2 virus, which causes covid-19, for five months, with the pathogen active and susceptible to transmission, according to a study released in the country by the Federal University of Rio de Janeiro (UFRJ).
The information is part of a study by the Molecular Virology Laboratory of the UFRJ, to which the Brazilian newspaper O Globo had access, and which indicated that the patient had no recurrence, but remained with the virus for 152 days, becoming the proven case. of contamination in one person, which lasted the longest, in the world.
The scientific research, carried out by the researchers Luciana Costa, Amilcar Tanuri and Teresinha Marta Castineiras, from the UFRJ, also argued that asymptomatic people are “the pillars of the spread” of the virus.
The patient, who was not identified, is a health professional from Rio de Janeiro, who in March presented mild symptoms associated with covid-19 and remained in home quarantine to receive medical advice. He returned to activity after spending the last five months completely asymptomatic.
The research, which performed molecular diagnostic tests on 3,000 people, includes other patients, mostly healthcare professionals, who never experienced symptoms again, but who continued to carry the active virus for several days.
Of these 3,000 patients, 50 who tested positive for COVID-19, and apparently recovered, returned, for various reasons, to undergo the clinical test and 15% of them still had the virus active.
The researchers found that in 40% of cases after fourteen days of quarantine, recommended by health authorities around the world, patients can still test positive for covid-19, but the virus, despite its presence in the body has no more transmission capacity.
Studies now aim to determine whether 35% of patients with the inactivated virus can develop antibodies, as opposed to the patient who stayed with the pathogen for five months and was unable to develop them.
However, they warned of the need to control vaccines, such as those that several countries have been developing, taking into account the case of the patient who incubated the virus for five months.
Brazil is the Portuguese-speaking country most affected by the pandemic and one of the most affected in the world, accounting for the second number of infected and dead (more than 3.9 million cases and 121,381 deaths), after the United States.
The coronavirus pandemic that causes covid-19 has already killed at least 851,071 people and infected more than 25.5 million people in 196 countries and territories, according to a report by the French agency AFP.
