H5N1 bird flu virus in cow milk may not respond to antivirals: Study reveals current drugs ineffective

Scientists found that frequently used flu antivirals do not work well against the H5N1 avian influenza virus in cows' milk. Preventive measures, such avoiding raw milk consumption and limiting exposure among dairy workers, may be the most efficient approach to defend against this H5N1 bird flu strain, as existing antivirals may be less effective against it.

Scientists are trying to learn more about the H5N1 virus's potential to harm human health as the avian influenza outbreak in the US continues. Scientists at St. Jude Children's Research Hospital are investigating possible cures for the virus after it was discovered in the milk of dairy cows and affected agricultural workers.

The findings indicated that two FDA-approved flu antivirals did not effectively cure severe H5N1 infections in a preclinical animal. The researchers also discovered that the efficiency of a treatment is greatly impacted by the infection's route, whether it be through the mouth, nose, or eye.
