Aside from the potential, of having a deadly virus transmitted to you by a mosquito bite, there can be many side effects and allergic reactions to the bite itself. Many of the mosquito saliva proteins can cause immune reactions, including allergic reactions. Typically, however, most people have a variety of reactions to mosquito bites, and the symptoms change over time, depending on the amount of bites a person received. These reactions can include both the immediate and delayed swelling and itching around the bite area. These reactions tend to decrease in frequency after being bitten by mosquitoes over many years. For example, I'm over 50 years old, when I'm bitten by mosquito, it doesn't leave a mark. My grandson, who is one-year-old, gets enormous welts, and swelling, from just one mosquito bite.
More severe reactions to mosquito bites are called, "Skeeter syndrome", rather than the typical itchy red bump experienced by most people as a result of a mosquito bite. These may result in blistering rashes, bruises, or large areas of swelling at the bite location. People, who experience extremely large areas of swelling after a mosquito bite, such as an entire arm or leg for example, would be considered as having "Skeeter syndrome". In rare situations, some people may experience anaphylaxis after being bitten by mosquitoes. Other people have experienced whole body urticaria andangioedemia, commonly known as hives or swelling, or worsening of asthma symptoms after being bitten. Typically, these symptoms occur within minutes after a mosquito bite, compared to Skeeter syndrome, which may take hours or days to occur.
People who are at higher risk of developing an allergy to mosquito bites should limit frequent exposure outdoors; if that's your job, get a new one. People with certain immune deficiency disorders, such as AIDS or cancers such as leukemia or lymphoma should steer clear of prime time feeding hours of mosquitoes outdoors. Find out if you're allergic to mosquitoes if you see some of the symptoms after being bit, would be to see it allergy specialist who could administer tests they can pin down your allergy. Maybe the best prevention, for somebody allergic to mosquito bites is stay indoors.
