    Acute HIV infection occurs in some individuals during the first 4 weeks after contracting the HIV virus. The virus rapidly attacks the immune cells and causes fevers, headaches, and sometimes a rash. The patient is highly contagious during this time as the viral load is high. Risk factors for transmitting HIV include unprotected sexual activity and contaminated needle stick injuries(e.g., via tattoos or sharing needles). Rarely, it is transmitted through the transfusion of blood products.
