Indirect impact of COVID-19 on the incidence rates of vector-borne diseases in Mexico

Gac Med Mex. 2022;158(6):349-354. doi: 10.24875/GMM.M22000712.


INTRODUCTION: SARS-CoV-2 infection spatial and temporal distribution overlaps with endemic areas of vector-borne diseases (VBD), whose surveillance in Mexico has substantially changed since the first COVID-19 confirmed case.

OBJECTIVES: To estimate and compare the incidence rates of VBDs before and after the introduction of SARS-CoV-2 in Mexico.

METHODS: Retrospective study of VBD cases from 2014 to 2021. The incidence rates of each VBD in the period before (2014-2019) and after (2020-2021) the introduction of SARS-CoV-2 in Mexico were calculated and compared.

RESULTS: Before the introduction of SARS-CoV-2, the incidence rates of VBDs were high and after the introduction of coronavirus there was a decrease in epidemiological indices; however, there was only statistically significant difference in the incidence rate of malaria (p ≤ 0.05) and other rickettsiae (p ≤ 0.05).

CONCLUSIONS: Some measures to reduce COVID-19 cases, such as social distancing, home confinement, reductions in public transport and working at home (home office), probably temporarily decreased the number of VBD cases; however, there may be a resurgence of VBDs in the near future.
