Confused About “Swine Flu”?
The H1N1 influenza virus has made
news headlines this year. If you’re still
confused, here are some answers
that will help you stay healthy.
Q: What is H1N1 flu?
It is a virus that causes illness in people.
It was originally referred to as
swine flu because it is similar to a
virus that normally occurs in pigs.
Cases have been reported around
the world, including in the U.S.,
Mexico, Canada, and Spain.
Q: How does it spread?
The virus is thought to spread the
same way that seasonal flu spreads—from person to person through
coughing or sneezing.
Q: How dangerous is this flu?
Researchers believe some people at
high risk for seasonal flu complications
face the same risk from H1N1
flu. These groups include:
- People with weakened immune
systems
- People with certain pre-existing
health conditions
- Residents of nursing homes and
other chronic-care facilities
However, unlike seasonal flu,
H1N1 infections have occurred
mainly in younger people. Research
suggests that many older adults
may have some degree of resistance
to the virus. One theory is
that older adults may have been
exposed to a related influenza A
virus that circulated before 1957.
