Abstract:
Lumpy skin disease is an emerging vector borne viral disease in India and was reported in many states including Karnataka. In the present study, index case was recorded in Bidar district in July 2020 and subsequently cases were reported from different talukas of Bidar district. The morbidity of LSD in Bidar district was 6.00 per cent and 0.17 per cent for cattle and buffaloes respectively and the overall morbidity rate was 3.55 per cent. Common clinical signs recorded were high fever, round circumscribed skin nodules, lymph node enlargement and brisket to limb edema. The age-wise and sex-wise prevalence study revealed, adult and male cattle were more susceptible to LSD. In case of breeds, all breeds were equally prone to infection. LSD infection peaked during the month of August through October and gradually decreased to lowest level during the month of December, which positively correlates significantly with temperature, relative humidity and rainfall (r=1.00). The climate with hot humid environment might have favored the up surging of vectors and occurrence of LSD in Bidar district. Vector study revealed, Haematobia (horn) flies that are suspected to be vector of LSDV were found to be predominant in the LSD affected farms.
