'The law is inherent in such situations and private hospitals have to comply with it. We haven't heard anything officially from Apollo Hospital and will take necessary legal action once we hear from them,' state Health Minister Kiran Walia said.

'We have given 15 days time to all private hospitals having more than 200 beds to keep at least 10 beds with isolation facility,' she added.

Meanwhile, some private laboratories Thursday said they will carry out swine flu tests in national capital region after getting a go ahead from the state government.

'A team of government experts had come to inspect our labs Wednesday but we are yet to get a go ahead. I need at least four days after the government approval to carry out swine flu tests,' Navin Dang, chief of Dr. Dang's Laboratories, told IANS.

'It is a huge responsibility on my shoulder and I want to make everything right,' Dang said whose laboratories are BSL-2 efficient.
