Sick after a mosquito bite?

C

My daughter got bit and they seemed up huge and hot, they went down after a few days but she started getting a bad fever and not eating and the bites are still red. My mom who works at a daycare has noticed similar things with every kid that has gotten bit this year. What is going on? Has anyone else experienced this??

(Currently trying to get my daughter to a doctor today so don't tell me to take because I already am)
