Zika virus cases spike in India's Jaipur as peak tourist season nears

MUMBAI (Reuters) - At least 55 people have tested positive for the Zika virus in India's tourist city of Jaipur, up from 22 a week ago, the local health department said on Sunday, raising fears the virus is spreading just ahead of peak tourist season.

Around 280 health officials are doing the rounds of houses in Jaipur in the western state of Rajasthan to detect larvae to control the mosquito-borne virus, the health department said in a statement late on Saturday.

Of the 55 people found to have tested positive for Zika over the past month in Rajasthan, 38 are no longer showing symptoms of the disease, the department said, adding that officials were conducting fogging to control the mosquito population.

Women in their first trimester of pregnancy are being paid particular attention, said Veenu Gupta, the additional chief health secretary of Rajasthan. Research has shown women are at greatest risk of microcephaly during this period.

There is no vaccine for Zika yet, though Japan's Takeda Pharmaceutical and some other companies are trying to developing one.
