What Diseases Could Cause a Fever?

Question

I had a fever of 39.5 degrees last night, took one pain reliever but the fever didn’t go down. Today, after receiving two intravenous drips (including fever-reducing, anti-inflammatory, and antiviral), the fever subsided. What kind of disease could be so stubborn? Thank you.

Answer

According to the description, a fever might be caused by the symptoms of catching a cold after exposure to cold, often accompanied by a runny nose, throat discomfort, and pain. It is recommended to take cold medication and antiviral drugs, and pay attention to rest and diet.
