Drug-resistant swine flu cluster on Vietnam train
ATLANTA, GA
Six were from a group of students, and the seventh was in a
different train car. They didn't know each other before the train
trip in July. They all got sick later, and recovered.
Vietnamese officials reported the cluster in a letter released
Wednesday by the New England Journal of Medicine.
Roughly 100 resistant cases have been reported worldwide since
the swine flu virus was identified in April. Tamiflu is one of two
flu medicines that help. Health officials have been closely
watching for signs that the virus is mutating, making the drugs
ineffective.
