Drug-resistant flu seen in patient

ATLANTA (AP) - Health officials have confirmed a case of swine flu that is resistant to Tamiflu, the leading pharmaceutical weapon against the new virus.

U.S. Centers for Disease Control and Prevention officials say the resistance was seen in a patient in Denmark. The good news is that scientists say the resistant strain developed in that one patient and has not spread to others.

Experts say Tamiflu resistance has developed in other types of flu, so this was not unexpected. But until an effective vaccine is developed, the drugs Tamiflu and Relenza are considered the best defense medicine has to offer.
