As the welts fade and tears dry, the long-term effects of wasp or bee stings can be much harder to see. After 135 students in Kamloops were stung by a rolling wasp nest alongside their Terry Fox Run, parents should be advised of an increased risk of potentially developing an allergy to future stings.

B次元官网网址淲ith allergies, what people often donB次元官网网址檛 realize is you have to be exposed or sensitized first before you can develop a bad allergic reaction with subsequent stings. Usually, the first sting is not the problem, itB次元官网网址檚 the subsequent stings,B次元官网网址 Dr. Donald Stark, a clinical associate professor with UBCB次元官网网址檚 allergy and immunology department, said.

If people have had a significant reaction before, thereB次元官网网址檚 a 60 per cent chance they will have an as bad or worse reaction to being stung again, he said. ThereB次元官网网址檚 no way to tell the next sting will instigate a big reaction, so Stark recommends looking at a family history of allergic reactions to insect stings. Even then, itB次元官网网址檚 not impossible that someone would develop an allergy after being stung.
