The buzz about
Mosquito Bite Frequency
If you've always suspected that mosquitoes prefer you to your friends, you're probably right. It turns out mosquitos do have preferences, and genetics may be partly to blame.
How it works
Mosquitos are drawn to breath and the body odor we emit from our sweat glands. It might make your skin crawl, but 23andMe researchers believe that mosquito bite frequency, as well as sensitivity to bites, is partly heritable.
The genetic link
23andMe researchers have identified 285 genetic markers associated with mosquito bite frequency, bite itchiness, or bite size. These markers along with non-genetic factors such as age and sex may affect whether you get more or fewer bites than the people around you.
Did you know?
Data from 23andMe customers who consented to participate in research indicate that more than a third, 37.5%, report being bitten more often than others. A little more than a quarter, 27.5%, said they were bitten less frequently than others.
Do mosquitoes swarm toward your scent? 23andMe's Health + Ancestry Service can tell you whether you're likely to get more or fewer bites than the people around you through our Mosquito Bite Frequency report.
