Hello friedhm, For an increase in temperature always take symptomatic relief as by paracetamol/acetaminophen.
If the temperature does not decrease in couple of days or remains over 104 degree Fahrenheit then consider an
examination near a physician and hospitalization for a proper diagnosis. If you have other symptoms like
increase in respiratory rate or silent chest, respiratory problems with asthma you would also need to visit a
hospital. Take care!
