Mosquitoes may be attracted and hence, more likely to bite THIS blood type

We all have to deal with pesky mosquitoes, especially in warm weather. No matter how many repellents and creams we use, these little creatures somehow find a way to come and bite us, even hovering around our heads all the time! However, have you ever noticed that there are some people who are more likely to be bitten by mosquitoes than others? These people are the first ones to lather themselves up with sprays and lotions, and do not leave the house before covering themselves up fully.
Research suggests that mosquitoes may be more attracted to certain blood types, making those individuals more likely to get bitten. Here's how blood type influences mosquito attraction and what other factors also play a role.
Let's know more about blood types
Blood types are categories based on the presence or absence of specific proteins called antigens on the surface of red blood cells. The four main blood types are:
Type A: Has A antigens
Type B: Has B antigens
Type AB: Has both A and B antigens
Type O: Has no A or B antigens
These antigens can also be secreted in body fluids like saliva and sweat in some people, known as "secretors" of their blood type.
Do mosquitoes prefer a blood type
Multiple studies have shown that mosquitoes tend to prefer people with blood type O over other blood types. For example, a study found that mosquitoes landed on people with type O blood twice as often as on those with type A blood. People with type AB blood were bitten the least, and type B was somewhere in between.
A 2004 study specifically looked at the mosquito species Aedes albopictus and found that mosquitoes landed significantly more on people with blood type O than on type A.

This was especially true for those who are secretors of their blood type antigens.
Why is O blood type a mosquito favorite
One reason might be related to the chemical signals mosquitoes detect on human skin. Blood type O individuals secrete a substance called the H antigen, which may be more attractive to mosquitoes than the A or B antigens present in other blood types. Mosquitoes use their sense of smell and other sensory organs to detect these antigens, which could explain their preference.
However, scientists caution that blood type is just one part of the story. Mosquitoes do not rely on blood type alone to choose their victims.
Other factors
Besides blood type, several other factors influence how attractive a person is to mosquitoes:
Body Odor: Mosquitoes are drawn to certain compounds on the skin like lactic acid and ammonia. The types and amounts of bacteria living on your skin also affect your smell, making some people more appealing to mosquitoes.
Carbon Dioxide: Mosquitoes can sense carbon dioxide that people exhale. Those who breathe out more carbon dioxide, such as people who are exercising, pregnant, or have a higher metabolic rate, tend to attract more mosquitoes.
Body Heat: Mosquitoes are attracted to warmth. People with higher body temperatures may get bitten more often.
Clothing Color: Dark colors like black, red, and dark blue attract mosquitoes more than light colors.
Alcohol Consumption: Drinking beer or alcohol may increase mosquito attraction, possibly by changing body odor or metabolism.
