The record of five months with the Sars-CoV-2 active and in transmission

Rio de Janeiro / A Brazilian patient carried Sars-CoV-2 for 152 days with the pathogen active and capable of transmission, which makes it the case with the greatest presence of the new coronavirus in a person in the world, according to a study published in the press local.

The study by the Molecular Virology Laboratory of the Federal University of Rio de Janeiro (UFRJ), to which the newspaper O Globo had access, indicated that the patient did not have recidivism, but remained with the virus for five months, in the case so far best known of persistence of the pathogen.

The work of the researchers Luciana Costa, Amilcar Tanuri and Teresinha Marta Castineiras, professors at the institutes of Microbiology and Biology and at the Faculty of Medicine of the UFRJ, sustains that asymptomatic people are “the pillars of the spread” of the virus.

The patient, who was not identified, is a professional from the Rio de Janeiro health area who in March had mild symptoms associated with COVID-19, remained in home quarantine for medical advice and then returned to her activities after spending the last five months completely asymptomatic.

The investigation

The research, which conducted molecular diagnostic tests on 3,000 people, includes other patients, mostly health professionals, who never again felt symptoms and continued to carry the active virus for several days.

Of those 3,000 patients, 50 who tested positive for COVID-19 and apparently recovered returned for different reasons to undergo the clinical test and in 15% it was detected that they continued with the active virus.

Those responsible indicated that in 40% of cases after the fourteen days of quarantine recommended by health authorities worldwide, patients can continue to test positive for COVID-19, but the virus despite its presence in the body does not it has more transmission capacity.

Studies now aim to determine if 35% of patients who carried the inactive virus managed to develop antibodies, different from the patient who remained with the pathogen for five months and failed to develop them.

However, they warned that as in the case of the patient who incubated the active virus for five months, control through vaccines is necessary, such as those that several countries have been developing.

Brazil is the second country most affected by the pandemic in the world, behind the United States, with more than 3.9 million confirmed cases and 121,000 deaths. (September 4, 2020, EFE / PracticaEspañol)
