Developments on swine flu worldwide

Key developments on swine flu outbreaks, according to U.S. Centers for Disease Control and Prevention, World Health Organization and government officials:

_Deaths: Global total of 76 — 68 in Mexico, six in U.S., one in Canada and one in Costa Rica. Officials said victims from Canada, U.S. and Costa Rica also had other medical conditions.

_Confirmed cases: WHO says 40 countries have reported more than 8,829 cases, mostly in U.S. and Mexico.

_CDC says 46 U.S. states plus District of Columbia have combined 5,123 confirmed and probable cases. Most probable cases are eventually confirmed.

_Dozens of countries urge WHO to change its criteria for declaring a pandemic to consider how deadly a virus is — not just how far it spreads. Britain, Japan, China and others cite potential consequences such as economic devastation and how vaccine decisions would be made.

_U.S. Health and Human Services Secretary Kathleen Sebelius told The Associated Press she wanted more information on the countries' proposal to WHO before taking a position.

_Acting CDC director says the outbreak is "not winding down" in the United States and "widespread transmission" continues. He says the epidemic is not over in Mexico.

_Japanese government says it will phase out airport quarantine checks after 41 more swine cases were confirmed in the port city of Kobe and nearby Osaka. A total of 176 cases have been confirmed in Japan, making it the fourth-most infected country in the world.

_China confirms its fourth case of swine flu on the mainland and says an Italian woman traveling in Tibet is also suspected of carrying the virus.
