Epidemiology of malaria in Chhattisgarh, India: a surveillance data analysis, 2015-2023.

ABSTRACT:

Background

India accounts for two-thirds of the malaria burden in Southeast Asia. We described the lab-confirmed malaria cases under the Integrated Disease Surveillance Programme in Chhattisgarh, India, from 2015 to 2023.

Methods

We conducted a surveillance data analysis by abstracting the lab-confirmed malaria cases from five regions of Chhattisgarh from January 2015 to December 2023. We estimated the annual parasite incidence (API) by region and year. We estimated the incidence rate ratio (IRR) with a 95% CI over the years using a generalized estimating equation in Stata 16.0.

Results

A total of 391 387 malaria cases were reported from 2015 to 2023. API ranged from 0.4-3.2 per 1000 population with an annual decline of 25% (IRR:0.75; 95% CI 0.71 to 0.79). Cases peake
