Low frequency of SARS-CoV2 infection in daycare centers during the reopening of school activities in the Southeast’s poor area of Brazil

SARS-Cov2 has already infected over 482 million people and caused more than 6.1 million deaths. The beginning of the pandemic has led the health authorities of several countries to adopt non-pharmacological preventive measures such as daycare closures. The reopening took place when the country had t...

description SARS-Cov2 has already infected over 482 million people and caused more than 6.1 million deaths. The beginning of the pandemic has led the health authorities of several countries to adopt non-pharmacological preventive measures such as daycare closures. The reopening took place when the country had the highest rates of infection and mortality (mainly due to the gamma variant (P.1) outbreak) and the beginning of the vaccination program. Therefore, we aimed to investigate the prevalence of SARS-CoV2 in daycare after educational activities resumed. The study was conducted in seven childcare facilities. Swab samples from the nasopharynx were collected from children and staff members. The viral RNA was obtained through PureLink RNA extraction kit purification and SARS-CoV2 presence was detected using the All plex SARS-CoV2 kit. The study population included 201 participants, including daycare workers and children. The average age of the workers and children is 40 and 3 years old, respectively. Among the children, 47.5% are female and among the workers, 91.4%. One (0.5%) test came out positive for the presence of SARS-CoV-2, which was from a sample of an asymptomatic childcare worker, and no secondary infections were detected. Considering that the return to daycare activities occurred during a period with a high number of deaths and a lack of vaccines throughout the country, the small number of cases indicates the effectiveness of the several preventive measures used by daycare centers in preventing SARS-CoV2 transmission.
