Thiruvananthapuram: Two more tested positive for Zika virus in Kerala on Tuesday, taking the total number of infections in the state to 21. The fresh cases were reported among Poonthura and Sasthamangalam residents. The infection was confirmed at the virology lab of the Thiruvananthapuram Medical College and the Coimbatore-based laboratory.
Kerala Health Minister Veena George directed the District Medical Officer to visit the affected areas and intensify preventive measures. Zika is transmitted mostly by the bite of an infected Aedes species mosquito and the only way to prevent the spread of the disease is to eliminate mosquito breeding grounds.
