Can Fly’s Cause Hives?
WouterWhile it may be hard to believe, flies can cause hives in some people. If you are prone to developing the symptoms, you should seek medical attention if you experience allergic reactions or an infection. Some people develop tularemia from flies, and it is important to avoid areas where flies are present. This includes forests, marshlands, and other areas with dense plant life.
Before seeking medical attention, your doctor will want to understand your medical history and the exact nature of your hives. He will ask you about any previous stings or bites that may have caused these symptoms. In addition, your allergist may want to perform one or more tests to determine whether you are allergic to insect venom. Some of these tests include blood tests and skin-prick tests.
Several allergens are found in the saliva of mosquitoes and may cause allergic reactions. The most common allergen is hyaluronidase. It is a highly conserved protein that is present in salivary glands of most blood-feeding insects. It is also present in the salivary glands of honeybees and wasps. The composition of these allergens is variable, and they may be cross-reactive.
Horsefly bites may also result in an allergic reaction. These bites are particularly painful, causing the affected area to itch and swell. In addition to being painful, horsefly bites can be infected with pus. Eventually, these bites will heal on their own, but you should seek medical attention if you suspect you are experiencing a fly allergy.
