What Blood Type Do Mosquitoes Love?

Mosquitoes are one of the most annoying creatures on this planet. Not only they make a buzzing sound that is enough to drive anyone crazy, but they also leave itchy and painful bites that can last for days. It is maybe one of the most painful experiences that one can encounter in summers. But, did you know that mosquitoes do not attack everyone randomly? Rather, mosquitoes have their preferences, and one of them is blood type. In this article, we will talk about what blood type do mosquitoes love and the science behind it.

The Science Behind Mosquitoes’ Attraction to Blood Type

Before talking about what blood type mosquitoes love, let’s delve into the science behind mosquitoes’ attraction to blood type. One of the main reasons that mosquitoes suck blood is to get access to proteins to nourish their eggs. Blood also contains essential nutrients such as iron and amino acids that help the mosquito survive. As mosquitoes evolved, they developed the ability to sense certain molecules in blood, which helped them to identify the type of animal they were feeding on. This sensory perception leads us to the fact that mosquitoes show preferences based on the blood type of the individual.

Blood Types

Human blood comes in four main types: A, B, AB, and O. These blood types are classified based on the presence or absence of molecules known as antigens on the surface of red blood cells. Type A has A antigens, Type B has B antigens, while Type AB has both A and B antigens. Type O has no A or B antigens. Presence of A or B antigens is significant because their presence produces specific sugars that mosquitoes seem to like. On the other hand, the absence of these antigens means no sugars, which makes that particular blood type less attractive to mosquitoes.

Blood Types Preferred by Mosquitoes

What blood type are mosquitoes attracted to most? According to a study in the Journal of Medical Entomology, mosquitoes are attracted to Type O blood more than any other blood types. The study found that mosquitoes landed on people with Type O blood almost twice as often as those with Type A blood, while Type B blood fell somewhere in between. This implies that both A and B antigens have some impact on mosquito’s preference, but Type O blood is the clear favorite blood type among these parasitic creatures.

Why are Mosquitoes Drawn More To Blood Type O?

One of the reasons behind the attraction of mosquitoes towards blood type O is that type O blood lacks antigens. This makes it easier for mosquitoes to “sense” and “bite” individuals with Type O blood. Mosquitoes are also attracted to carbon dioxide which is produced when we exhale. People with Type O blood have a higher metabolic rate, which results in the production of more carbon dioxide. Mosquitoes use this as a cue to locate their next victim.

Blood Type and Malaria

Malaria is one of the world’s deadliest diseases, and mosquitoes are responsible for spreading malaria. Many studies have suggested that certain blood types are more susceptible to malaria than others. The same study mentioned above also found that individuals with Type O blood are more susceptible to malaria because of the presence of certain sugars on the surface of their red blood cells that seem to attract mosquitoes. People with Type O blood are also more likely to get bitten by other mosquito-borne diseases like Dengue fever, West Nile virus, and Zika virus.

Can We Alter Our Blood Type To Avoid Mosquitoes?

Many people wonder if they can alter their blood type to make themselves less attractive to mosquitoes? The answer is No. Blood type is determined by genetics and cannot be altered. However, there are certain steps that you can take to reduce the chances of getting bitten by mosquitoes. One can use mosquito repellents or bug sprays, wear light-colored and loose-fitting clothes, and use mosquito nets. Also, get rid of standing water in your area and avoid going outdoors during dawn and dusk when mosquito activity is at its peak.

Conclusion

There is no doubt that mosquitoes are annoying, and getting bitten by them can be painful. But, understanding what blood type mosquitoes love can help you take necessary precautions to avoid them. Eating garlic, drinking beer, and taking vitamin B12 supplements do not make you less attractive to mosquitoes. However, ensuring that you are protected from mosquito bites can save you from many mosquito-borne diseases. Stay safe, and stay healthy!
