ABSTRACT
OBJECTIVE: To analyze notifications of flu-like syndrome according to the time interval between onset of symptoms and testing for COVID-19. METHODS: This was a cross-sectional study using records of flu-like syndrome cases containing results of COVID-19 diagnostic tests in the Brazilian state capitals and Federal District, held on the e-SUS Notifica system, from March 1st, 2020 to August 18th, 2020. The time interval between symptom onset and testing was compared using the ANOVA test, classifying it according to test adequacy/timeliness. RESULTS: Taking 1,942,514 notifications, average time between symptom onset and testing was 10.2 days (±17.1). Among those tested, females (55.1%), people aged 20-39 years (43.8%), and the Southeast region of Brazil (43.0%) predominated. 58.8% of IgM ELISA tests were performed at an adequate time while 68.0% of rapid antigen tests were not performed at an adequate time. CONCLUSION: Inadequacy was found between symptom onset and time taken to test for COVID-19 in the Brazilian regions.

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), classificando-o segundo a adequação/oportunidade do exame. Resultados Entre 1.942.514 notificações, o tempo médio entre início dos sintomas e execução dos testes foi de 10,2 dias (±17,1). Entre testados, predominou o sexo feminino (55,1%), idade de 20-39 anos (43,8%) e região Sudeste (43,0%). O teste ELISA IgM foi realizado em tempo adequado para 58,8%;e o teste rápido-antígeno, em tempo inadequado para 68,0%. Conclusão Observou-se inadequação entre início dos sintomas e realização dos testes para COVID-19 nas regiões brasileiras.

El ELISA IgM se realizó en momento adecuado para 58,8% y la prueba de Antígeno Rápido en momento inadecuado para 68,0%. Conclusión Se constata inadecuación de tiempo entre el inicio de los síntomas y las pruebas para COVID-19 en las regiones brasileñas.
