New Delhi: Two more people have been confirmed positive for Japanese Encephalitis in the city, taking the total number of patients suffering from the mosquito-borne disease to 14. According to Dr V K Monga, the MCD health committee chairman, they have not found the source of the infection yet. “The blood samples collected from pigs in the affected areas and the ones being slaughtered have tested negative. Now, we are going to expand the screening process further and samples will be collected from at least 500 pigs to be sent to the National Research Centre for Equines at Hisar in Haryana for tests,” he said. Monga added that pigs are the amplifying host for Japanese Encephalitis. “In Delhi, there are two types of pigs: the local ones and those brought in from other states for slaughtering. If the local ones are found infected from the virus, we may have to relocate them and in case of the latter found carrying the virus we will have to ban the imports to check spread of the disease,” Monga added.
