Can mosquito bites cause fever?

Can mosquito bites cause fever?

No: Mosquito bites, by themselves, should not cause fever. Bites become "inflamed" commonly (not infected) and can be red and a bit swollen, but again no fever. True "infection" is quite uncommon.

That said, mosquitoes, in certain parts of the world, can transmit all kinds of infections which can cause fever: malaria, dengue fever, yellow fever, are all spread by the bite of an infected mosquito. ...Read more

Hi dr I have mosquito bites with bruises I got them sunday they hurt but I don't have a fever or any other symptoms but pain?

Swat! Swat!: Sounds like you have an over sensitivity to the bite. There is a protein in their saliva to keep your blood from clotting. When they bite you that gets injected into you along with their saliva. Some times humans have an exaggerated response to this protein. This is known as the "Skeeter" syndrome. Time should take care of the problem. ...Read more

Fevers: Fevers for the most part aren't dangerous and are just the body's natural reaction to fighting off an infection. Most of these infections are viral and may be accompanied by runny nose, sore throat, congestion, mild rash, or nothing at all. Since fevers aren't dangerous, we usually treat the fever with Acetaminophen or Ibuprofen just to make the child more comfortable as their body fights the illness.

"red flags" that we look for with fever to indicate something more serious is going on are:
-fevers that last 5 days or more
-fevers persistently above 104f orally
-a child that acts very sick - very irritable or difficult to wake
-difficulty breathing
-vomiting, diarrhea, refusal to drink, or dehydration
-a purple rash, esp on the legs
-stiff neck
-any complaints of pain such as the ear, throat, stomach or a joint

since she is crying as if something is hurting her, you should call her doctor and have her seen. As always, use your judgement. If you think that your child is ill, err on the side of caution and call your child's doctor. ...Read more
