New Delhi: H1N1 influenza cases have increased in Delhi and parts of North India in recent weeks, with experts advising people, particularly those at higher risk of complications, to take precautions but stressed that there is no evidence of the virus becoming more virulent.
Speaking to PTI Videos, former WHO chief scientist and former ICMR director general Dr Soumya Swaminathan said H1N1 is a known strain of influenza and not a new virus.
