Hi, I'm starting to worry about my condition..
- I'm 22 years old male with no major illness history.
- I began to have a constant fever of about 38.5C five days ago, with no sign of getting better.
- There is no other symptoms - this is weird since I always had something like coughing and sore throat accompanying the fever.

Could someone please advise what I should do? Also, is this condition likely to be contagious?

Thank you so much.
