Likewise, if an individual suspects exposure for HIV, a lack of symptoms does not indicate that seroconversion has not occurred. 20–30% of people undergoing HIV seroconversion lack symptoms entirely or have mild symptoms. [25] The immune system mounts an acute effort to resolve the HIV infection during the seroconversion period.
During this period (usually days to weeks post-exposure) fifty to ninety percent of infected individuals develop an influenza or mononucleosis-like illness called acute HIV infection (or HIV prodrome), [2] [3] the most common symptoms of which may include fever, lymphadenopathy, pharyngitis, rash, myalgia, malaise, mouth and esophageal sores ...
The eclipse period is a variable period starting from HIV exposure in which no existing test can detect HIV. The median duration of the eclipse period in one study was 11.5 days. The window period is the time between HIV exposure and when an antibody or antigen test can detect HIV. The median window period for antibody/antigen testing is 18 days.
HIV is a retrovirus that primarily infects components of the human immune system such as CD4 + T cells, macrophages and dendritic cells. It directly and indirectly destroys CD4 + T cells. [88] HIV is a member of the genus Lentivirus, [89] part of the family Retroviridae. [90] Lentiviruses share many morphological and biological characteristics.
The window period for HIV may be up to three months, depending on the test method and other factors. RNA based HIV tests has the lowest window period. Modern and accurate testing abilities can cut this period to 25 days, 16 days, or even as low as 12 days, again, depending on the type of test and the quality of its administration and interpretation.

There is an initial period of influenza-like illness, and then a latent, asymptomatic phase. When the CD4 lymphocyte count falls below 200 cells/ml of blood, the HIV host has progressed to AIDS, [ 1 ] a condition characterized by deficiency in cell-mediated immunity and the resulting increased susceptibility to opportunistic infections and ...
At this point, seroconversion, the development of antibodies, occurs and the CD4 T cell counts begin to recover as the immune system attempts to fight the virus, marking the HIV set point. The higher the viral load at the set point, the faster the virus will progress to AIDS ; the lower the viral load at the set point, the longer the patient ...
