Flu and Covid: winter could bring 'double-barrel' outbreak to US, experts say

But the same measures that fight coronavirus are effective against the flu - and vaccines offer another weapon against it

Public health experts, researchers and manufacturers warn the coming flu season could bring a double-barrel" respiratory disease outbreak in the United States, just as fall and winter are expected to exacerbate spread of Covid-19.

At the same time, researchers said the strategies currently used to prevent Covid-19 transmission - namely, hand-washing, mask-wearing and social distancing - could also help lessen flu outbreaks, if Americans are willing to practice them.
