New Delhi: World Health Organisation while declaring the Pandemic to be over in August 2010, conveyed that the influenza H1N1 pandemic virus would take on the behaviour of seasonal influenza virus and continue to circulate for some years to come. 

Hence, in the post-pandemic period, localized outbreaks of varying magnitude with significant level of H1N1 transmission are expected.

In the post pandemic period, our country had experienced outbreaks during the period August to October, 2010; May to July 2011; March and October 2012 and now in January –February 2013. 

Increase in number of cases of Influenza A H1N1 are being reported presently from the States of Delhi, Gujarat, Haryana, Rajasthan and Punjab. Small pockets of population who remained unexposed to the pandemic and susceptible would be affected.

A large number of these cases would be presenting with mild influenza like illness and as such requires no testing or anti-viral drug treatment. 

However, it is important to get oneself examined at the nearest hospital in the initial part of illness to detect moderate illness and other associated risk factors/ diseases that require hospitalization.

The anti-viral drug Oseltamivir is available free of cost through the State public health system. A central stockpile of about 5.5 million tablets of Oseltamivir is also maintained.

As the virus is circulating within the country, there is no need to impose any travel restrictions or screening at inter-state point of entry, railway stations etc.

The situation is well under control and is being monitored.
