- 虫咬和身体的反应本身就可引起发热和其他全身性反应，您太太一开始的尿，关节的问题（如果医护人员没有搞错的话）说不定也是全身反应之一。一开始发热不一定需要细菌。当然细菌现在肯定有，而且刚刚被消灭了很多。Skip to main navigation

Signs and symptoms of an insect bite result from the injection of venom or other substances into your skin. The venom causes pain and sometimes triggers an allergic reaction. The severity of the reaction depends on your sensitivity to the insect venom or substance and whether you've been stung or bitten more than once.
Most reactions to insect bites are mild, causing little more than an annoying itching or stinging sensation and mild swelling that disappear within a day or so. A delayed reaction may cause fever, hives, painful joints and swollen glands. You might experience both the immediate and the delayed reactions from the same insect bite or sting. Only a small percentage of people develop severe reactions (anaphylaxis) to insect venom. Signs and symptoms of a severe reaction include:
- Nausea
- Facial swelling
- Difficulty breathing
- Abdominal pain
- Deterioration of blood pressure and circulation (shock)
Bites from bees, wasps, hornets, yellow jackets and fire ants are typically the most troublesome. Bites from mosquitoes, ticks, biting flies, ants, scorpions and some spiders also can cause reactions. Scorpion and ant bites can be very severe. Although rare, some insects also carry disease such as West Nile virus or Lyme disease.
