Hello- My 9 year old son has had a low-grade fever and a cough for 8 days. His illness started suddenly with a higher fever of 101-102 degrees and also a headache and slight stomach upset. After day 3, he seems to feel fine and is fever-free during the day, other than the cough, but in the evening he runs a slight fever around 99-100 degrees. We do not have insurance, and my husband was recently laid off. We're trying to determine if this is more than likely just a virus, or a bacterial infection before we decide if he needs to be seen.
