Resumen
This study aimed to analyze how meteorological conditions such as temperature, humidity and rainfall can affect
the spread of COVID-19 in five Brazilian (São Paulo, Rio de Janeiro, Brasília, Manaus and Fortaleza) cities. The cities selected were those with the largest number of confirmed cases considering data of April 13. Variables such as
number of cumulative cases, new daily cases and contamination rate were employed for this study. Our results
showed that higher mean temperatures and average relative humidity favored the COVID-19 transmission, differently from reports from coldest countries or periods of time under cool temperatures. Thus, considering the
results obtained, intersectoral policies and actions are necessary, mainly in cities where the contamination rate
is increasing rapidly. Thus, prevention and protection measures should be adopted in these cities aiming to reduce transmission and the possible collapse of the health system.
