Hyderabad: Health authorities here have sent for testing the samples of a 52-year-old man from Hyderabad, who returned from Nigeria, as a measure of caution against Ebola.

The man was suffering from fever and took treatment at a corporate hospital here, but was referred to the state-run Gandhi Hospital. "As per the definition of WHO, he is not a suspect also. Nigeria is already declared as Ebola free by WHO on October 19," said Dr K Subhakar, the nodal officer for infectious diseases like Ebola.
