NewsInhaling ethanol may treat respiratory infections
Inhaling low concentrations of ethanol vapour can disable the influenza A virus in mice, without harmful side effects, says a new study by scientists at the Okinawa Institute of Science and Technology (OIST). The scientists believe it may also treat similar viruses such as the one that causes Covid-19. ...
