Rare drug-resistant flu variant identified in the US, CDC says

·1 min

A variant of the flu that is resistant to a commonly used antiviral treatment has been detected in the US, according to the US Centers for Disease Control and Prevention (CDC). The variant has two mutations that could reduce the effectiveness of the treatment. However, the threat is currently considered to be low, as the variant represents only about 1% of the samples collected worldwide. The effectiveness of other antiviral treatments and flu vaccines is not affected by the variant. The CDC is closely monitoring the situation to assess any potential public health threats.
