Entomological Survey for CCHF Vectors in Palghar District of Maharashtra
In view of reports of alert issued by Department of Animal Husbandry, Government of Maharashtra for Crimean Congo Hemorrhagic Fever (CCHF) in Palghar district, a visit was planned from 2-5 October 2020 to assess the situation and vector surveillance of ticks was carried out in the district. There is no past history with any report of CCHF cases in the district. However, there have been reported outbreaks of dengue and malaria during 2018 & 2019 as per IDSP data. The department of Animal Husbandry had initiated tick reduction activities in the bordering 19 villages with Gujarat using the chemical compounds (Deltamethrin, Cypermethrin). No confirmed cases of CCHF have been reported in District Palghar so far. During tick surveys in 4 villages and a dairy farm, heavy infestation of Boophilus Sp. (60-70%) mainly on cows and buffaloes.Hyalomma Sp. (30-40%) was observed mainly on goats which is the main vector responsible for CCHF. The infected ticks were found to be Boophilus microplus, Hyalomma anatolicum, Hy. marginatum and Rhipicephalus sanguineus species.Guidelines on proper dosage for the formulations of insecticide being used and spray techniques need to be followed up on the animals by the field staff and officials of Animal Husbandry department.
