J Vector Borne Dis. Jan-Mar 2021;58(1):28-32. doi: 10.4103/0972-9062.321746.


Background & objectives: Jammu and Kashmir is bestowed upon by great climatic condition favourable for people but the vectors have utilised these conditions to gain access into the state. Vector Borne Diseases (VBDs) were restricted to the spread of malaria and dengue since past two decades, but now, these diseases have widened their geographical reach and in last six years chikungunya, leishmaniasis and Japanese encephalitis have been reported from the state. These VBDs are a threat to thousands of people in the state as they cause huge mortality and morbidity under extreme cases.

Methods: A hospital-based survey on the VBDs was carried out with the aim of studying the prevalence of major VBD found in the Jammu district taking into account the past records provided by the Directorate of Health Services, Jammu.

Results: The study revealed that malaria, in the past 14 years, has now shown a clear declining trend and dengue cases have shown a very uneven trend with maximum cases in 2013. Leishmaniasis was reported for the first time in the division in 2013, while it was not until 2016 when single case of chikungunya was reported from Jammu division. First outbreak of Japanese encephalitis in the region occurred during 2018 from only Doda district.

Interpretation & conclusion: The present study showed that despite having congenial environmental conditions, Jammu division faces a great threat of VBDs and the increase in the number of cases in future cannot be ruled out. Japanese encephalitis registered its presence for the first time in the division.
