Prevent Swine Flu

Pneumonia and Influenza Hospitalization and Death Tracking system was implemented on August 30, 2009, and replaces the weekly report of laboratory confirmed 2009 H1N1-related hospitalizations and deaths that began in April 2009. Jurisdictions can now report to CDC either laboratory confirmed or pneumonia and influenza based counts of hospitalizations and deaths resulting from all types or subtypes of influenza, not just those from 2009 H1N1 influenza virus. To allow jurisdictions to implement the new case definition, counts were reset to zero on August 30, 2009. From August 30 – October 10, 2009, 4,958 laboratory-confirmed influenza associated hospitalizations, 292 laboratory-confirmed influenza associated deaths, 15,696 pneumonia and influenza syndrome-based hospitalizations, and 2,029 pneumonia and influenza syndrome-based deaths, were reported to CDC. CDC will continue to use its traditional surveillance systems to track the progress of the 2009-10 influenza season.

A flu pandemic occurs when a new influenza A virus emerges for which there is little or no immunity in the human population. As we have seen the virus causes serious illness and spreads easily from person-to-person worldwide. On June 11, 2009, the World Health Organization (WHO) declared that a global pandemic of H1N1 flu is in progress. Nearly 5,000 people have died from swine flu infections since the A(H1N1) virus made its debut in April, the World Health Organization said on Friday. The death toll marked an increase of about 265 over the 4,735 deaths reported to the WHO a week ago.  The majority of the fatal cases which number 3,539 have been recorded in North and South America, the UN health agency said in its latest update on the escalating flu pandemic.

Overseas countries like Iceland, Sudan, and Trinidad and Tobago reported their first fatal cases over the past week.  Mongolia, Rwanda, and Sao Tome and Principe also recorded pandemic influenza cases for the first time, as the virus continued to spread.  Perhaps some good news is the  A(H1N1) influenza was declining in tropical areas of the world.  That is with the exception of Cuba and Colombia.  There was also no significant pandemic related activity over the past week in warmer areas of the southern hemisphere, the WHO said.  At this time respiratory disease activity persists in spreading and growing in intensity in the northern hemisphere, predominately in North America.  Extensive efforts are ongoing to track and monitor the spread of all flu viruses. In the U.S., epidemiologists at the Centers for Disease Control (CDC) are working diligently with the states affected to collect, compile and analyze reports of flu outbreaks.  As of September 2009, the current calculations are that about 90,000 deaths will take place in the U.S. from novel H1N1 swine flu. This is the estimate set out by the president’s advisory committee. There has been no revision of these numbers by the advisory committee or the CDC as of October 2009.
