Eighteen more people in Rajasthan's Jaipur district have tested positive for Zika virus, taking the total number of such cases to 50, a Union Health Ministry official said Friday.
At least 10 of the news cases were reported from Jaipur's Shashtri Nagar locality.
The figures were issued after a review meeting chaired by Rajasthan Health department's Additional Chief Secretary, Medical and Health, Veenu Gupta on Friday.
The first case had surfaced on September 22. Fogging and other anti-larvae activities are being carried out in the Shastri Nagar area to prevent the spread of the virus.
Earlier, a department official had said that 30 of the total cases were doing fine after treatment.
At the review meeting, measures taken to contain the situation were discussed.

A team from the National Institute of Malaria Research (NIMR) recently found Zika virus in some mosquitoes taken as samples from Shastri Nagar, leading to suspicion they are behind the infection.
Dr Neena Valecha, the NIMR director, had earlier said the virus appears to be locally transmitted.
The state government has been provided information, education and communication (IEC) material prepared to create awareness about Zika virus and prevention strategies.
The Zika virus, transmitted through Aedes aegypti mosquito, causes fever, skin rashes, conjunctivitis, muscle and joint pain. It is harmful to pregnant women, as it can lead to microcephaly, a condition in which a baby's head is significantly smaller than expected, in newborn children.
In India, the first outbreak was reported in Ahmedabad in January 2017 and the second was reported in Tamil Nadu's Krishnagiri district in July that year. Both these outbreaks were successfully contained through intensive surveillance and vector management, the ministry had said earlier.
The disease continues to be on surveillance radars of the Union Health Ministry although it is no longer a Public Health Emergency of International Concern under WHO notification since November 18, 2016.
