The human swine flu outbreak continues to grow in the United States and internationally. Today, CDC reports additional cases of confirmed swine influenza and a number of hospitalizations of swine flu patients. Internationally, the situation is more serious too, with additional countries reporting confirmed cases of swine flu. In response to the intensifying outbreak, the World Health Organization raised the worldwide pandemic alert level to Phase 4. A Phase 4 alert is characterized by confirmed person-to-person spread of a new influenza virus able to cause “community-level” outbreaks.” The increase in the pandemic alert phase indicates that the likelihood of a pandemic has increased.
The situation continues to evolve rapidly. As of 19:15 GMT, 28 April 2009, seven countries have officially reported cases of swine influenza A/H1N1 infection. The United States Government has reported 64 laboratory confirmed human cases, with no deaths. Mexico has reported 26 confirmed human cases of infection including seven deaths.
The following countries have reported laboratory confirmed cases with no deaths - Canada (6), New Zealand (3), the United Kingdom (2), Israel (2) and Spain (2).
Further information on the situation will be available on the WHO website on a regular basis.
