Summer is definitely the season for mosquitoes. You need to know when you have an insect bite, what is a normal bite and what is not. A red dot that stings, itches, and goes away in 24 to 48 hours is a normal and typical reaction. An atypical reaction is when perhaps the bite stays red for longer than normal, emits fluid, or when there’s a rash (urticaria), or when there is swelling, or when there is perhaps a systemic reaction.
When there is truly an allergic reaction, a patient may have a systemic effect, such as difficulty breathing, or hives outside the area of the bite. Those are signs and symptoms of a reaction that’s out of the ordinary and more aggressive. And it would require emergency treatment.
