The Union ministry of health and family welfare has said there is no mutation in H1N1 (swine flu) to suggest change of virus to dangerous form. The government also said there was no need to impose any travel restrictions or screening at inter-state point of entry, railway stations.
Director of National Institute of Virology, Pune, said the presently circulating strain of H1N1 virus belongs to clade 6 and 7 (a medical term used to describe related organisms descended from a common ancestor). These clades can be cured with Oseltamivir, an antiviral drug which slows the spread of influenza virus.
