Text2009 H1N1 Influenza
Post Pandemic Period
On August 10, 2010,
the World Health Organization stated that the world is no longer in phase 6 of
influenza pandemic alert and that the new H1N1 virus has largely run its
course.
The post-pandemic period does not mean that the H1N1 virus has gone away. Based on experience with past pandemics, we expect the H1N1 virus to take on the behavior of a seasonal influenza virus.
Pandemics, like the viruses that cause them, are unpredictable. So is the immediate post-pandemic period. Continued vigilance is extremely important, and WHO has issued advice on recommended surveillance, vaccination, and clinical management during the post-pandemic period.
2009 H1N1 History
In the Spring of 2009, a new flu virus spread quickly across the United States and the world. On June 11, 2009, the World Health Organization (WHO) declared a pandemic of H1N1 influenza indicating that the new virus has become widespread. The world sees its first pandemic declaration in over 40 years. The World Health Organization (WHO) International Health Regulations (IHR) Emergency Committee declared an end to the 2009 H1N1 pandemic globally on August 10, 2010.
