Trend of Zoonotic Diseases Outbreaks in India: a secondary data analysis of Integrated Disease Surveillance Programme data, 2010- 2023

Background: Zoonotic diseases are occurring more frequently in different parts of the world. In country like India many of the outbreaks are being reported by the Integrated Diseases Surveillance Program (IDSP). The objective of the study is to find the trend of zoonotic diseases as reported in the IDSP portal. Methods: Data was collected from the IDSP portal from January 2010 to December 2023. Data were collected regarding the outbreak's start date, the number of cases, and the number of deaths. A total ten diseases were included in the study. The data was entered in MS Excel and analysis was done using Stata-12 and MS Excel. Results: From all the reported outbreaks a total of 1158 outbreaks were reported of the selected zoonotic diseases. JE/ AES was the most commonly reported outbreak. Anthrax, JE/ AES, CCHF, Leptospirosis, and Scrub outbreaks and cases were reported throughout the year. The majority of diseases were reported in the rainy season in the months July to September. Conclusion: Although an increasing trend of the selected zoonotic diseases is reported in the current study, the data must be interpreted cautiously keeping in mind the limitations of reporting. Activities may be planned based on burden estimation to prevent the morbidity and mortality associated with the diseases.
