Relationship between temperature and relative humidity on initial spread of COVID-19 cases and related deaths in Brazil

Abstract: Introduction: Climate conditions may influence the transmission of COVID-19. Thus, the aim of this study was to evaluate the impact of temperature and relative humidity on COVID-19 cases and related deaths during the initial phase of the epidemic in Brazil. Methodology: An ecological study based on secondary data was conducted. Daily data on new COVID-19 cases, deaths, and climate indicators were collected from February 20 to April 18, 2020 (n = 59 days) for all state capital cities in Brazil and the Fed… Show more

“…The instantaneous analysis of the interaction indicates a change in the sign of the causality. This non-linear behavior may explain some contradictory results reported in the literature regarding positive [ 89 ], negative [ 90 ], or even no correlations [ 91 ] between RH on COVID-19. This intrinsic dynamic characteristic of a natural ecosystem justifies the use of CCM to capture the evolution of the causation, which can be masked or reverse its direction depending on the period of time being considered.…”
