Did you take your baby's temperature using a thermometer? (digital preferably) or you simply used the back of your palm? Running temperature (Fever) is defined as a temperature of 37.5°C and above. So Kindly take her temperature with a thermometer. If indeed she's having a fever, you can give an appropriate dose of paracetamol to help calm it temporarily and then visit a paediatrician for evaluation. Meanwhile, a mosquito bite isn't enough to say your baby will surely come down with malaria (bcos I guess that's what you're thinking it is ) no need to worry, kindly use a thermometer
