Influenzas [noun]

It quickly published results of an early human test of a new mRNA influenza vaccine and would initiate a large series of clinical studies involving diseases including Zika.

The phenomenon is not only in the United States — worldwide, rates of influenza are nearly off-the-charts low.

In that month alone, influenza claimed the lives of nearly 200,000 Americans, roughly quadrupling the country’s combat deaths for the entire war period.

Vaccinations for influenza, pertussis and polio, for example, can stop people from getting severely ill if infected, but those people could still be contagious.

Coronaviruses, which generally show less seasonal variation than the influenza virus, tend to have a weak response to changing temperatures.

One study found that surgical masks protect the wearer from influenza virus in droplets and aerosols by an average of 80 percent.

We also have not seen significant influenza or RSV on our wards in Colorado.

Some, like influenza, evolve quickly with thousands of mutations and distinct lineages, while others are more stable.

We could be walking around in the middle of summer with influenza viruses, but they’re not active.

It takes even the influenza virus five to seven years to become so different as to evade the vaccine entirely.
