Figure 1. Early Symptoms of HIV. The stages of HIV infection are acute infection (also known as primary infection), latency, and AIDS.Acute infection lasts for several weeks and may include symptoms such as fever, swollen lymph nodes, inflammation of the throat, rash, muscle pain, malaise, and mouth and esophageal sores.
After the virus enters the body there is a period of rapid viral replication, leading to an abundance of virus in the peripheral blood.During primary infection, the level of HIV may reach several million virus particles per milliliter of blood.
Without treatment, the average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype. [4] In most cases, HIV is a sexually transmitted infection and occurs by contact with or transfer of blood, pre-ejaculate, semen, and vaginal fluids.
After the latency period (but before clinical infection) the infected person can transmit the disease without signs of any symptoms. Such infection is called subclinical infection.

A course of antiretrovirals administered within 48 to 72 hours after exposure to HIV-positive blood or genital secretions is referred to as post-exposure prophylaxis (PEP). [144] The use of the single agent zidovudine reduces the risk of an HIV infection five-fold following a needle-stick injury. [144]
One potentially life-threatening example is meningitis, which can cause chills with or without a fever, along with symptoms like a stiff neck, sensitivity to light and sound, and lethargy.
HIV infection has a long period during which the person is asymptomatic. [19] Although the host may not be experiencing symptoms, the virus can still be passed on to others. It is also possible for the infection to become symptomatic after this incubation period.
