Common biting insects such as mosquitos and midges have a need to satisfy their blood hunger and bite victims to attain their blood meal while simultaneously injecting saliva. Their saliva consists of a number of immunogenic substances which may consequently evoke immune reactions such as anaphylaxis amongst bacterial infections like cellulitis. Nevertheless, the common simple bites experienced by the UK population are not accompanied by such serious reactions.
Currently, there are a variety of over-the-counter preparations including topical corticosteroids and antihistamines which aim to relieve the common symptoms of itching, swelling and pain. However,
Drug and Therapeutics Bulletin researchers claim there is a lack of evidence to prove the efficacy of such insect bite treatments. If this is true then there is a dangerous possibility that this may be misinterpreted as evidence that is not effective which may preclude the population from seeking medical help in event of an insect bite.
Even though the majority of cases involve simple bites which usually resolve themselves over several days with the aid of simple treatment like cold compression over the affected area instead of suggested over-the-counter preparations, it is possible that an insect bite can lead to complications including infection and in more serious cases result in anaphylactic shock. For such serious reactions, medical attention and treatment must be sought after immediately which without may lead to death.
Therefore it is important to promote an unambiguous health message to the public and it should be made clear that lack of evidence does not equate to evidence that is not effective. Otherwise, there may be a risk of serious cases going unnoticed.
