Abstract: Resumo Objetivo Analisar as notificações de síndrome gripal segundo o intervalo de tempo decorrido entre início dos sintomas e realização do exame para COVID-19. Métodos Estudo transversal, utilizando registros de casos de síndrome gripal contendo resultados de testes diagnósticos da COVID-19 nas capitais brasileiras e no Distrito Federal, no sistema e-SUS Notifica, entre 1º/março/2020 e 18/agosto/2020. Comparou-se o intervalo de tempo entre início dos sintomas e realização do exame (teste ANOVA), classifi… Show more

“…It is appropriate to speculate on the late approach of symptomatic HCWs based on these recommendations that consider the period of symptoms. The mean between the onset of symptoms and the test for COVID-19 was 10.2 days [22] in the federal district and capitals of the Brazilian states. The high incidence rate of registered FS cases in HCWs compared to the GC can also be attributed to the access criteria.…”

“…Notification of the SF case is mandatory. Therefore, the expectation is that all cases that meet the notification criteria (flu-like syndrome) will be identified and registered in this system [22,23]. As the data depends on registration in health services, there are potential biases of underreporting due to access to these services.…”

“…The serial interval (SI), defined as the time between the onset of symptoms in the source of infection and in the recipient, was modelled as a gamma distribution with a mean of 6·5 days with a standard deviation of 4·03 days 37 . A fixed value of 10 days was used for the delay between symptom onset and case reporting, this was consistent with an average value of 10·2 days for 2,420,904 suspected COVID-19 cases reported between March 1 st and August 18 th 2020 in all the state capitals and Federal District of Brazil in the e-SUS notification system 38 . Predictions were only made for municipalities with more than 30 days of data and more than 200 COVID-19 cases reported, to allow sufficient data for the algorithm to give reliable estimates 39 .…”

“…Os testes rápidos para a COVID-19 trazem como vantagens a facilidade de execução de uma rápida resposta dos resultados, contudo, vale ressaltar que a taxa de eficácia é variável de acordo com o fabricante (Santos et al, 2021). Estes testes que detectam antígeno e anticorpo possuem características distintas sobre a perspectiva de tempo de coleta, onde estudos mostram que o período adequado do antígeno varia entre 2 e 7 dias, já a coleta do anticorpo seria no período maior que 8 dias (Teixeira et al, 2020). Kweon et al, (2021) avaliaram 2 tipos de testes rápido para antígeno, onde as amostras foram confirmadas por testes moleculares anteriormente.…”
