The WHO released an FAQ around the announcement of pandemic level 6 for A/(H1N1). The question and answer provided about severity is provided below:
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.
