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 ...
WHO Disease Staging System for HIV Infection and Disease was first produced in 1990 by the World Health Organization [1] and updated in 2007. [2] It is an approach for use in resource limited settings and is widely used in Africa and Asia and has been a useful research tool in studies of progression to symptomatic HIV disease .
Following infection with HIV, the rate of clinical disease progression varies enormously between individuals. Many factors such as host susceptibility and immune function, [2] [3] [4] health care and co-infections, [5] [6] [7] as well as factors relating to the viral strain [8] [9] may affect the rate of clinical disease progression.
While many different things can cause diarrhea—including infections or a more serious gastrointestinal condition—in most cases, it will go away after a few days without the need for treatment.
Main symptoms of acute HIV infection. The initial period following infection with HIV is called acute HIV, primary HIV or acute retroviral syndrome. [29] [30] Many individuals develop an illness like influenza, mononucleosis or glandular fever 2–4 weeks after exposure while others have no significant symptoms.
These infections are often acquired from food or water that has been contaminated by feces, or directly from another person who is infected. [2] The three types of diarrhea are: short duration watery diarrhea, short duration bloody diarrhea, and persistent diarrhea (lasting more than two weeks, which can be either watery or bloody). [2]
A drug holiday (sometimes also called a drug vacation, medication vacation, structured treatment interruption, tolerance break, treatment break or strategic treatment interruption) is when a patient stops taking a medication(s) for a period of time; anywhere from a few days to many months or even years if the doctor or medical provider feels it is best for the patient.
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. Incubation period (also known as the latent period or latency period ) is the time elapsed between exposure to a pathogenic organism, a chemical, or radiation , and ...
