Resumen
NAVARRO-DURAN, Antonio y CORTEZ-HUERTA, Mauro. Impact of relative humidity on COVID-19 transmission. Rev Cub Sal Públ [online]. 2022, vol.48, n.3 Epub 01-Ago-2022. ISSN 1561-3127.
Introduction:
The new pathogen SARS-CoV-2 presents a rapid spread, and is the cause of the Coronavirus disease 2019 (COVID-19). Given that this virus is recent, the increase in cases of the COVID-19 disease has been a great threat, to which has been added the lack of conclusive information about the disease, its transmission, and its relationship with the different environmental variables.
Objective:
To determine the incidence of relative humidity in the transmission of COVID-19 in the tropical regions of Colombia.
Methods:
Relative humidity data and number of daily COVID-19 infections from seven cities in Colombia located in the Caribbean Region (Barranquilla and Sincelejo), Andean region (Medellín, Bucaramanga, Armenia and Cúcuta), as well as the Amazon Region (Leticia) were analyzed. A generalized logistic model was used to analyze existing data and design epidemiological curves.
Results:
For all cities, according to the model, high correlations were found between relative humidity (observed variable) and COVID-19 (predicted variable) with an R2 > 0.90. However, it was determined if there was an association between the variables by comparing the p-value with the level of significance α 0.05, a statistically significant association was found in the cities of Leticia, Barranquilla and Cúcuta.
Conclusions:
The results indicate that there is a direct relationship between relative humidity and the transmission of COVID 19 in tropical regions of Colombia. Hence, it is proposed that the study provides an important tool for the decision-making of the institutions in charge of the control of the disease, such as national and local governments.
