Hyderabad, July 14 (Inditop.com) The swine flu scare forced IT major Google Tuesday to shut down its Hyderabad office for two days as a precautionary measure.

A company spokesman confirmed that Google has announced two-day holiday for all its employees at the office here to enable them undergo screening for Influenza A(N1H1).

Over 1,000 employees of the firm were told to contact the Andhra Pradesh Chest Hospital after one employee was tested positive for the swine flu.

He was among the six employees of three IT companies who contracted the virus from a software engineer, who returned to the city from Houston July 5, according to health authorities.

The 29-year-old techie, who approached the Chest Hospital July 11 after he developed swine flu symptoms, spread the infection to employees of the IT companies with whom he worked.

The techie and six others were tested positive Monday, spreading the swine flu scare in IT companies in Madhapur here. Employees of one company have already started taking medicines as a precautionary measure.

Health authorities said the swine flu symptoms in the techie could not be detected despite compulsory screening of all air passengers at the Rajiv Gandhi International Airport here. This was the first cluster formation in the city.

With eight new cases including a two-and-half-year-old boy who arrived here from Dubai, the swine flu cases in the city has gone up to 31.
