Influenza poses one of many world’s biggest infectious illness challenges.
CDC packages shield america from seasonal influenza, as nicely
as pandemic influenza which happens when a brand new flu virus emerges that
can infect folks and unfold globally.
Influenza is at all times altering
Flu viruses change consistently, from season to season
and generally in the course of the season.
Flu vaccines should be up to date ceaselessly to maintain up
with these modifications.
Annually, influenza causes thousands and thousands of diseases,
a whole lot of 1000’s of hospitalizations, and tens
of 1000’s of deaths.
Seasonal flu causes illness and dying
9.three – 45* million
U.S. flu burden every year since 2010
Novel influenza viruses are at all times rising
Most influenza viruses don’t unfold in folks, however
unfold in animals, particularly wild birds and pigs.
A number of of those animal influenza viruses can unfold to
folks, and in uncommon circumstances, could trigger a pandemic.
Periodically, extra cases of animal influenza
viruses infecting individuals are reported.
Folks could have little or no immunity to pandemic
influenza so the implications may be a lot higher.
Animal influenza viruses can unfold to folks
An influenza pandemic can emerge anyplace and unfold globally
4 influenza pandemics have occurred prior to now
The 1918-19 flu pandemic was essentially the most extreme,
killing 675,000 People and 50 to 100 million
Throughout a pandemic:
drugs could also be briefly provide
vaccines might not be available
