What is phase 6? (WHO)
Updated 11 June 2009 by WHO
Phase 6 is a pandemic, according to the WHO definition.
What about severity?
At this time, WHO considers the overall severity of the influenza pandemic to be moderate. This assessment is based on scientific evidence available to WHO, as well as input from its Member States on the pandemic's impact on their health systems, and their social and economic functioning.
The moderate assessment reflects that:
* Most people recover from infection without the need for hospitalization or medical care.
* Overall, national levels of severe illness from influenza A(H1N1) appear similar to levels seen during local seasonal influenza periods, although high levels of disease have occurred in some local areas and institutions.
* Overall, hospitals and health care systems in most countries have been able to cope with the numbers of people seeking care, although some facilities and systems have been stressed in some localities.
WHO is concerned about current patterns of serious cases and deaths that are occurring primarily among young persons, including the previously healthy and those with pre-existing medical conditions or pregnancy.
Large outbreaks of disease have not yet been reported in many countries, and the full clinical spectrum of disease is not yet known.

Vaccines for the new influenza A(H1N1)
2 May 2009 (From WHO)
Is an effective vaccine already available against the new influenza A(H1N1) virus?
No, but work is already under way to develop such a vaccine. Influenza vaccines generally contain a dead or weakened form of a circulating virus. The vaccine prepares the body’s immune system to defend against a true infection. For the vaccine to protect as well as possible, the virus in it should match the circulating “wild-type” virus relatively closely. Since this H1N1 virus is new, there is no vaccine currently available made with this particular virus. Making a completely new influenza vaccine can take five to six months.

1. real-time RT-PCR
2. viral culture
A probable case of novel influenza A (H1N1) virus infection is defined as a person with an influenza-like-illness who is
* positive for influenza A, but negative for human H1 and H3 by influenza RT_PCR
