This syndrome may be mistaken for an infection such as cellulitis. In anaphylactic patients the response is more aggressive leading to a systemic reaction where the response progresses from the sting site around the whole body. This is potentially something very serious and can lead to anaphylaxis, which is potentially life-threatening. [3] [4]
Anaphylaxis can occur in response to almost any foreign substance. [20] Common triggers include venom from insect bites or stings, foods, and medication. [10] [21] Foods are the most common trigger in children and young adults, while medications and insect bites and stings are more common in older adults. [3]
Symptoms following the attack can range from inflammatory reactions to severe allergic reactions resulting in anaphylactic shock. In some cases, death may occur following several stings and a large amount of venom injection; however, a wasp sting typically will not produce a reaction more severe than local symptoms that affect only the skin.

[67] [68] [69] Wasp nests made in or near houses, such as in roof spaces, can present a danger as the wasps may sting if people come close to them. [70] Stings are usually painful rather than dangerous, but in rare cases, people may suffer life-threatening anaphylactic shock. [71]
In addition to stings and bites causing discomfort in of themselves, bites can also spread secondary infections if the arthropod is carrying a virus, bacteria, or parasite. [8] The World Health Organization (WHO) estimates that 17% of all infectious diseases worldwide were transmitted by arthropod vectors, resulting in over 700,000 deaths ...
Most humans can withstand many stings, but others may suffer from severe reactions such as anaphylaxis. [45] People who are stung by red imported fire ants may experience intense local burning or flare-ups, followed by reddening of the skin at the sting site. This area will swell into a bump, hive or vesicle within 20 minutes. White fluid ...
As with other wasps, death due to a single sting on the skin only occurs when an allergy is present, and serious outcomes with Asian giant hornet stings in China and Japan are only documented with many stings or anaphylactic shock due to an existing allergy. [12] People who are allergic to wasp venom may also be allergic to hornet stings.
