LONDON (AP) - The World Health Organization says healthy people who catch swine flu don't need antiviral drugs like Tamiflu.
In new advice issued to health officials today, the U.N. agency said doctors don't need to give Tamiflu to healthy people who have mild to moderate cases of swine flu.
WHO said the drug should definitely be used to treat people in groups at risk for the virus. That includes children less than five years old and people over age 65, among others.
The new advice contradicts government policies such as those in Britain, which has been giving out Tamiflu to all people suspected of having swine flu.
WHO also urged nations to speed up their preparations for swine flu, warning of "an explosion" in cases until peak transmission of the flu is reached. WHO says most countries may see swine flu cases double every three to four days -- for several months.
