OKLAHOMA CITY, Okla_ The influenza virus started circulating early last
year, driving up infection numbers across the nation, and Oklahoma is no
different.
More than 600 Oklahomans have been hospitalized because of flu, and
at least 14 have died from the virus since September 30.
Though the Centers for Disease Control said this
year's seasonal shot was a good match for the expected influenza viruses, it
only blocks infection between 50 and 70 percent of the time, said Oklahoma
Medical Research Foundation President Stephen Prescott, M.D.
In other words, even people who got the shot can
still be at risk.
"The flu vaccine is the best way to protect yourself,
but it's not the only way," Prescott said. "We don't stop using the brakes on
our cars just because there are also airbags and seatbelts. Just because you got
a flu shot doesn't mean you shouldn't practice basic flu
precautions."
Washing hands is important regardless of the season,
and it can prevent the spread of influenza viruses very well. The three main
access points for viruses are the eyes, nose and mouth—all places most likely to
be touched by hands. Washing keeps viruses from walking in an open
door.
"The influenza virus is hardy. It can live on
surfaces for up to 8 hours," Prescott said. "If you touch communal-use objects,
from a door handle to a table, wash your hands afterward or use hand sanitizer
until you can get to a sink."
Mothers tout this one as common courtesy, but
covering the mouth and nose with a tissue when coughing or sneezing can lessen
the spread of flu as well. If there isn't a tissue nearby, use the crook of your
elbow.
Those who do get sick should do their part to stop
the misery of the flu in its tracks.
"Within 48 hours of getting sick, see a doctor and
ask about antiviral treatments like Tamiflu," he said. "They can reduce the
impact and length of the illness by prohibiting the virus from spreading to new
cells in the body."
To avoid spreading the virus, patients should avoid
other people if possible.
"It may seem rude at first, but people tend to
understand and appreciate it when you explain you don't want to share your
illness," he said.
People are most likely to infect others with the flu
starting about a day before their symptoms begin and through the first five to
seven days of the illness. Once you start to feel better, you're not likely to
pass it on to anybody else, Prescott said.
If all goes well, most people are clear of the flu
after a week or so. But if it sticks around longer, return to the doctor,
Prescott said. A virus that hangs around can give birth to a secondary infection
or even pneumonia.
"There is no silver bullet to absolutely ensure you
won't get the flu," he said. "But if you take reasonable precautions, your
chances of avoiding a week of body aches, sneezing and nausea will improve
significantly."
