Abstract

Background: Mosquito-borne diseases like malaria and dengue are significant public health concerns in India, particularly in tropical regions.Objective: To analyze the trend of malaria and dengue cases in a tertiary care centre in Madhya Pradesh over a 3-year period.Methods: This retrospective study analyzed 1,284 malaria and 1,043 dengue cases reported from January 2022 to December 2024. Data was collected from hospital records and laboratory reports.Results: Malaria cases decreased by 32.6% (From 521 in 2022 to 351 in 2024), while dengue cases increased by 49.8% (From 281 in 2022 to 421 in 2024).
