When you hear the words, “Lyme Disease,” you think of ticks, but some studies are being released with findings that Lyme can be carried by mosquitoes as well. A scientific study out of Germany is showing that mosquitoes can carry Borrelia and claiming that there is a capability to transmit the disease.

What Does the CDC think about these claims from Germany?

 “[t]here is no credible evidence that Lyme disease can be transmitted through air, food, water, or from the bites of mosquitoes, flies, fleas, or lice.” 

This is becoming a split in the scientific community for the level of health concern that is actually present. Are mosquitoes a vector of concern for Lyme Disease? Much of the controversy about mosquitos not being a true vector is due to the fact that mosquitoes do not embed themselves. They attach for such a short amount of time, minutes if not seconds. Ticks, on the other hand, can embed for days allowing for transmission of Borrelia.

What did this study actually consist of?

The researchers sought to find out if Borrelia can be found in different species and if there is a presence of Borrelia in mosquitoes right after their metamorphosis. Researchers found that Borrelia was detectable in 10 species across 4 different genera; this was out of the 52 species of mosquito tested in Germany.  This research is important to understanding Borrelia but does not present a health scare for a spread of Lyme. Such a short amount of time for the mosquitoes to feed limits the spirochetes’ ability to transmit Lyme through a bite.

This is just another study confirming how difficult this spirochete is to get rid of due to its incredible survival techniques in the body. St, ll there is a great deal to learn about Borrelia and its transmission from tick to host; in the meantime be aware of possible signs of being infected with Lyme Disease.
