The UN health agency said people who are otherwise healthy with mild to moderate cases of A (H1N1) flu don't need the popular drug. But people thought to be at risk for complications(并发症) from A (H1N1) flu—children less than five years old, pregnant women, people over age 65 and those with other health problems like heart disease or HIV—should definitely get the drug.
The WHO also recommended that all patients, including children, who have severe or worsening cases of A (H1N1) flu, with breathing difficulties, chest pain or severe weakness, should get Tamiflu immediately.
The advice contradicts(与……矛盾) some current government policies, such as those in England, whose health agency liberally hands out Tamiflu to healthy people with A(H1N1) flu cases; Tamiflu has been available to anyone suspected of having the disease, including healthy people.
At its summer peak, there were about 110 000 new cases of A(H1N1) flu, also known as swine flu, every week in Britain. Boasting that Britain had the world's largest supply of Tamiflu, enough to cover 80 percent of its nearly 61 million people, Andy Burnham promised the drug would be available to anyone who needed it. Britons who call the national flu line can get Tamiflu without ever seeing a doctor—it is given out by call center operators who have no medical training.
Some experts have criticized that approach, warning that blanketing the population with Tamiflu increases the chances of resistant strains emerging. Flu expert Hugh Penington of the University of Aberdeen called the strategy “a very big experiment” and said England's approach was out of step with the rest of the world. WHO said most patients infected with A(H1N1) flu worldwide recover within a week without any medical treatment.
