Amazing Fact: Type O Blood Attracts Mosquitos0
The very first (many have followed) research study was done in 1972. This study showed that mosquitoes have a blood-type preference, favoring type O blood over type A or B blood. A followup study also looked at secretor status and concluded that mosquitoes prefer type O secretors above all. Scientists have isolated proteins on mosquitoes’ antennae that detect chemical markers emitted from peoples’ skin, but still don’t know why certain blood types are favored over others.
Although this is not a found the results of these studies fascinating.
