Are there allergic reactions to mosquito bites? Answers from Dr. Badran

Mosquitoes are cold blooded creatures. They differ from humans in that their body temperature is adjusted based on their current location.

This is why mosquitoes, like the majority of other insects, tend to be more visible during the hottest times of the year. Mosquitoes found in temperate regions tend to hibernate a lot. There are over 3,500 different species of mosquitoes ready to ooze your blood.

Mosquito bites are the itchy bumps that appear after mosquitoes use their mouthparts to pierce your skin and feed on your blood. The bump usually goes away on its own within a few days. Sometimes a mosquito bite causes a large area of ​​swelling, pain, and redness. This type of reaction, most common in children, is sometimes called skeeter syndrome.

Male mosquitoes do not bite

Male mosquitoes do not bite people and animals. Since males do not bite, they cannot transmit disease. Like all living creatures, mosquitoes need some form of sustenance to survive. Both male and female adult mosquitoes actually feed on nectar, plant sap, or honeydew for food. Only female mosquitoes need a blood meal, as it provides the protein needed for egg laying. Apart from blood meals, males and females have the same diet.

Female mosquitoes bite humans and animals to feed on blood. Mosquitoes drink up to three times their weight in blood. Most female mosquitoes cannot produce eggs without a blood meal. They need protein and iron from the blood to produce eggs. After drinking blood, they find stagnant water and lay their eggs there. Female mosquitoes lay up to 300 eggs at a time. The eggs hatch into larvae, then into pupae, and then they become adult mosquitoes.

Males live for about a week to ten days, and females can live up to several weeks. Some female mosquitoes can hibernate in the winter and live for months.

Symptoms of Mosquito Bites

Some people have only a mild reaction to one or more bites. Other people react more strongly and a large area of ​​swelling, pain and redness may occur.

Normal mosquito bites can trigger immediate swelling and redness that peaks after about 20 minutes, followed by small, itchy bumps that are usually less than 2 centimeters in diameter.

Signs of mosquito bites include: a swollen, white, reddish bump that appears minutes after the bite a hard, itchy, reddish-brown bump or multiple bumps that appear about a day after the bite(s) small blisters instead of hard bumps and dark spots that look like bruises.

More severe reactions can be experienced by children, adults who have not been exposed to the type of mosquito that bit them, and people with immune system disorders. In these people, mosquito bites sometimes trigger: a large area of ​​swelling and redness, mild fever, hives and swollen lymph nodes.

Children are more likely to develop a severe reaction than adults, as many adults have had mosquito bites throughout their lives and become unresponsive.

Sketer syndrome

Skeeter syndrome is a relatively rare inflammatory reaction to mosquito bites. Symptoms can develop hours after a mosquito bite and can include a large area of ​​swelling, warmth, redness, itching, and pain that mimics what would happen with an infection.

The brand is bigger and more durable. The welts can swell 2 to 10 centimeters in diameter within an hour of being bitten and progress over the following days. The bumps can be itchy, red, painful, and hot to the touch.

Skeeter syndrome is the result of an allergic reaction to proteins found in mosquito saliva. Almost everyone is susceptible to mosquito bites. But for people with severe allergies, the symptoms can be more than just annoying: they can be serious. Most bites occur at dusk or dawn, when mosquitoes are most active.

Risk factors

Mosquitoes bite anyone. However, certain factors can cause mosquito bites. These include: men, pregnant women, people who are overweight or obese, people with type O blood, people who have recently exercised, people who emit higher amounts of acid uric acid, lactic acid and ammonia and people who have recently drunk beer
Mosquitoes can detect carbon dioxide from a distance of 75 feet. Carbon dioxide, produced by humans and other animals, is actually a key signal to mosquitoes that a blood meal is near.

They are very sensitive to the CO2 present in the air. A female mosquito moves back and forth through the CO2 plume until she locates her victim.

Also, since mosquitoes are attracted to heat, wearing dark colors can make you more susceptible to being bitten. This is because dark colors absorb heat. People living in humid tropical climates or swamps are also at higher risk of bites.

Some people also have a greater risk of an allergic reaction, such as young children. People who are allergic to some of the components of mosquito saliva, such as proteins and antimicrobial agents, may also be at higher risk of developing Skeeter syndrome.


Do not scratch the bites. They can be infected. An infected bite may appear red, feel hot, or a red streak will spread from the bite.

Mosquitoes currently kill more than a million people each year. Mosquito-borne diseases are increasing with climate change. The risk of developing serious illness is the most dangerous result of a mosquito bite. Bites from mosquitoes carrying certain viruses or parasites can cause serious illness. Infected mosquitoes in many parts of the world transmit West Nile virus to humans. Other mosquito-borne infections include yellow fever, malaria, and certain types of brain infections (encephalitis). If a person notices a mosquito bite and experiences flu-like symptoms or a fever, they should seek medical attention immediately.

Prevent mosquito bites

As with other allergies, prevention is the best approach. Mosquitoes need still or stagnant water to breed. If possible, avoid standing water, especially at dusk and dawn when mosquitoes are most active.
Eliminate standing water around the house by: unclogging gutters, emptying kiddie pools, cleaning birdbaths, and emptying unused containers like flower pots.

Other ways to prevent mosquito bites include: wearing light-colored protective clothing such as long-sleeved shirts, long pants, socks, and a wide-brimmed hat, and patching holes in window screens or doors.
