Bug Bites

DEM says EEE found nearby…James Canyon Virus…Why they bite you…Why you need to take the pledge…And stick on a patch
By Will Collette

Eastern Equine Encephalitis (EEE, Triple E) was found in mosquitoes trapped in nearby Voluntown, CT, leading the DEM and RI Department of Health to step up their caution to residents to take steps to avoid getting bitten. We all already know this is a bad year for bugs, so be careful out there.

Connecticut health officials are alarmed because this is the earliest in the season that they’ve seen EEE show up in their tests.

They are also sounding the alarm for residents to take extra measures to prevent bites.

Jamestown Canyon Virus? WTF?

As if West Nile and EEE wasn’t bad enough, the Connecticut Agricultural Experiment Station in Stonington trapped mosquitoes carrying the Jamestown Canyon Virus.

This bug is classified as a “bunyavirus” and is rarely found in humans, although that could change, given the high number of mosquitoes and corresponding mosquito bites this year. The James Canyon virus attacks the central nervous system.

Why me?

Smithsonian Magazine did a great piece answering that question. They noted there are lots of factors at work that make some people more attractive to mosquitoes than others. Some examples:

Blood Type. Type O gets bit the most. Type A the least. Mosquitoes are twice as likely to bite a person with Type O blood than Type A.

Weight, exercise and smell. Mosquitos are far more likely to bit adults than children and not just because adults are bigger. They are drawn to exhaled carbon dioxide which is one reason why they are drawn to you when you exercise and sweat. They also like lactic and uric acid excretions, also associated with exercise and sweat. And they like skin bacteria which may account for why they often bite ankles and feet.

Pregnancy. Pregnant women get bitten twice as often as the general population.

Clothing Color. Mosquitoes like to go after people who wear black, dark blue or red clothing. It makes you easier for them to see.

And, oh the horror

Just one 12 oz. can or bottle of beer will make you far more attractive to mosquitoes. Unfortunately, researchers haven’t been able to figure out why.

Given the dire implications of these findings, I would think a emergency crash research program is needed.

Is this patch the cure?

A new anti-mosquito product is coming out that is supposed to act as an invisibility cloak for humans, allowing them to escape mosquito detection for up to 48 hours. Called the Kite Patch, it is FDA-approved and supposedly non-toxic. It sticks to clothing.

The Kite Patch will be tried out in Africa first where mosquito-borne diseases (malaria, West Nile, etc.) exact a terrible toll.

The Kite Patch inhibits mosquitoes’ ability to detect the carbon dioxide you excrete (see previous Bug Bits segments). It was developed with support from the Bill and Melinda Gates Foundation and the NIH.


It will not be marketed in the US until it is certified by the EPA. The FDA approval, and successful trials in Africa, should help.
