H1N1 pandemic is over, WHO declares
The Geneva-based World Health Organization announced Tuesday that the H1N1 virus that grew to pandemic levels has largely run its course.
While localized outbreaks may continue, WHO Director-General Dr. Margaret Chan said the virus has moved into a "post-pandemic period." A pandemic was declared in June 2009 for the influenza strain commonly known as "swine flu."
As of Aug. 1, more than 214 countries, territories or communities worldwide had confirmed cases of the virus that has caused at least 18,550 deaths.
