BENGALURU: In view of the Zika virus case reported in Kerala, routine surveillance activity in rural areas by ASHA workers and health assistants, and fortnightly surveillance activity in urban wards will be implemented on a war footing in Karnataka. The border districts of Dakshina Kannada, Udupi and Chamarajanagar have been advised to be more vigilant. 

“The current monsoon season supports the widespread proliferation of the Aedes mosquito, which is a vector for the Zika virus,” stated a circular from the health commissionerate. The Zika virus symptoms are fever, rashes, conjunctivitis, joint pain etc.  District Vector Borne Disease Control officers have been instructed to intensify vector management through environmental modification or manipulation, surveillance of both adult mosquito and larvae, adopting personal protection measures, and biological and chemical control at the household, community and institutional level.

“Aedes larval surveillance and source reduction activities in airports, sea ports, harbour, villages and wards in a 2-km vicinity should be carried out with necessary vigil,” the circular read, adding that travel history or visit of guests may also be considered for suspecting Zika. The samples will be sent to the National Institute of Virology, Bengaluru.
