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 for 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 with a positive COVID-19 test, and apparently recovered, returned, for various reasons, to undergo the clinical test and 15% of them still had the active virus.
