美国缓解学校对H1N1流感政策
This is the VOA Special English Health Report.
More than twenty countries have found cases of the new H1N1 influenza virus. In all around one thousand five hundred cases and thirty deaths have been confirmed. But most have been reported in Mexico and, to a much lesser extent, the United States. The virus was discovered in Mexico in the middle of March.
On Tuesday, federal officials in the United States advised schools not to close anymore when they have cases. The new health secretary, Kathleen Sebelius, said the virus does not seem to be as severe as once thought.
The World Health Organization will not declare an influenza pandemic unless a virus becomes widespread in at least two areas of the world. The W.H.O. is advising people to wash their hands often with soap and water. And it says there is no risk of infection from eating well-cooked meat from pigs.
The virus is commonly called swine flu because it contains some genetic material from pigs. But it also contains material from humans and birds.
