The World Health Organization says the H1N1 swine flu virus has spread to almost every country in the world, killing about 800 people since it emerged in April.
A spokesman for the U.N. agency, Gregory Hartl said Friday that one of WHO's main priorities is to furnish developing countries with vaccines to fight the virus. He said the first vaccines will be available before cold weather arrives in the Northern Hemisphere in a few months. The United States could begin human trials for a vaccine early next month. The WHO spokesmansaid there were more than 130,000 laboratory-confirmed cases of swine flu before the agency stopped reporting them last week, and he estimated the number of people infected has grown to hundreds of thousands by now.
The White House said Friday that it has been holding regular meetings to prepare for an expected spike in U.S. infections after September.
