With the neighbouring state of Rajasthan reporting 135 positive cases of Zika virus, as a precautionary measure, the Gujarat health department has surveyed around 4.22 lakh people in Ahmedabad since Sunday.
While no positive cases have been found so far, the state is on alert owing to high migration rate between the two states.
According to official data, on Wednesday alone 1,94,205 persons were surveyed in Ahmedabad within one to three km radius of contact with suspected persons. Over 1200 teams of Ahmedabad Municipal Corporation officials have been conducting the surveys since Sunday.
A total of 70,419 houses have been surveyed for possible breeding grounds of the Aedes aegypti mosquitoes, which is responsible for the spread of the virus.
In these houses, 2,277 containers were found to be positive breeding grounds for the mosquito and a total of 22,039 houses have been sprayed.
AMC medical officer Bhavin Solanki said that out of all the people surveyed, 786 were pregnant women. Of these, 200 women with a history of fever were also screened in Ahmedabad.
The Gujarat director of National Health Mission (NHM) Gaurav Dahiya said that no confirmed cases of the virus have been recorded from the state so far. According to the official data, ‘no person with fever/symptoms consistent with Zika virus disease’.
“There is a procedure of keeping a close watch on people who have travelled from Rajasthan. Suspected cases are sent to BJ Medical College, Ahmedabad one of the eight laboratories authorised by the state government to test the virus,” Dahiya said.
Dahiya said that he had issued advisories to all municipal corporations and district panchayats on October 9 to apprise them of the guidelines to be followed.
In May 2017, the state had received flak when WHO reported the first three cases of Zika virus in the country from Ahmedabad. The cases corresponded to January 2017. However, the government was accused of withholding this information until May.
