Americans Ignoring Mosquito-Bite Risk
60% of U.S. Not Using Bug Repellent; 'What, Me Worry?' Attitude Cited
July 18, 2005 -- One mosquito bite can paralyze you for life. But
hey, why worry about it?
That attitude is frustrating public health officials worried about the
spread of West Nile virus and other mosquito-borne diseases.
Mid-July means the U.S. is entering peak West Nile virus season. Yet most
Americans still aren't doing enough to fight the bite, says behavioral
scientist Emily Zielinski-Gutierrez, DrPH, at the CDC's Division of
Vector-Borne Diseases in Ft. Collins, Colo.
"It really comes down to the fact that people are not enough afraid of
West Nile virus to do something about it," Zielinski-Gutierrez tells WebMD.
"People are actively choosing not to use mosquito repellent."
Americans on West Nile Virus: 'What, Me Worry?'
The active ingredient in most bug repellents is a chemical called DEET. Are
we more afraid of DEET than of mosquitoes? Not most of us. In fact, a recent
CDC survey shows that only half of Americans even know what DEET is.
The survey, conducted in October 2004, probed the reasons why we aren't
using mosquito repellent.
"We asked why: Is it because it smells? Is it because you are concerned
about the health effects of DEET? But less than 15% of people say these
things," Zielinski-Gutierrez says. "Almost half of people say, "I
just forgot about it," or "I didn't see any mosquitoes," or "I
just wasn't thinking about it."
In 2003, Colorado had nearly 3,000 cases of West Nile virus. This year, at
the CDC's annual West Nile virus conference, Colorado Department of Public
Health epidemiologist John Pape offered a "top 10 list" of reasons why
people don't wear DEET-containing repellents:
10. I'm not sure why I didn't use
9. I'm too lazy/I didn't have time.
8. I used other methods to avoid mosquito bites.
7. It smells bad.
6. (tie) I didn't have any repellent.
Mosquitoes don't bite me.
5. I don't go outside.
4. I'm concerned about health effects of DEET.
3. I forgot.
2. I don't see mosquitoes where I live.
1. I'm not worried/I'm not at risk.
Are these good excuses? Zielinski-Gutierrez doesn't think so.
"One mosquito bite can transmit West Nile virus," she warns.
"Putting on repellent takes a few seconds and can avoid the potential
lifelong implications of getting infected."
It's especially important for the over-50 crowd to use repellent. West Nile
disease is particularly dangerous for those over 50 -- yet people over 50 are
among those least likely to use repellent.
New Repellents Available
This year, the Environmental Protection Agency (EPA) announced that two new kinds of mosquito repellents
work as well as DEET, although for shorter periods of exposure.
One is picaridin. The other is a chemical extract called oil lemon
