Hey there!
HIV is a virus and it can be transmitted through contact with infected blood, semen, or vaginal fluids. It's a pretty rare diease.
Within a few weeks of HIV infection, flu-like symptoms such as fever, sore throat, and fatigue can occur.
If the diease gets serious, it can cause weight loss, fever or night sweats, etc...
Hope this helps you!
Hugs!
