These symptoms of acute, sometimes vague, indefinite HIV infection occur within up to one month after initial infection and may last for about two weeks.
They may extend for a longer or shorter period of time, being very similar to influenza or any other virus, since, in _virus_ known as HIV. Human Immunodeficiency Virus is even a virus, whose signs appear between two to four weeks after the infection.
Not all newly infected people live this picture known, too, as the acute phase and many of those who experience it do not suffer from this picture in a specific way, with symptoms as already said similar to those of any respiratory viruses common to mankind.
Acute infection is the period of time immediately after contact between the human body and HIV, the human immunodeficiency virus. During this period, a few days after infection, HIV replication is done extremely rapidly with the generation by HIV of many copies of itself, leading to an extremely high amount of HIV RNA in the blood, an index known as Viral Load (click here to learn more: What is Viral Load? - opens in another tab). This is so because the body's defenses have not yet been able to respond effectively to HIV.
As the amount of HIV increases in the body, a large number of white blood cells, called CD4 + T cells (or CD4, which is actually the name of one of the cell receptors used as the "key" to the ___ Invasion of the cell_) , responsible for the defense of the body, which are destroyed at a dizzying pace.
The course of HIV infection causes a large, drastic, dramatic and catastrophic decrease in the number of CD4 cells and also / and in the quality of these CD4 cells, weakening, little by little, the immune system which will, at some point, lead to AIDS, which is an acronym for an expression that in free translation is called "Acquired Immunodeficiency Syndrome" that would have its definition better addressed as "AIDS." This is an excellent reason for you, who maintains an active sex life and who had some relationship without a condom, test yourself for HIV after at least 30 days after this relationship! Thirty days is the minimum consistent and definitely consistent response time for what is known as the Immune Window (the link opens on another tab of your browser and I advise you to open the link for an absolutely necessary supplementary reading later
About six to eight weeks after acquiring HIV infection, the body begins to defend itself by creating antibodies. The development of antibodies causes the amount of HIV to fall, but the virus still remains in the blood, and never completely disappears.
The period known as acute HIV infection may be referred to by different names, such as primary HIV infection, acute retroviral syndrome, and acute HIV infection syndrome. All names describe this rapid phase immediately following HIV infection.
The researcher at the National Institute of Infectology (INI / Fiocruz), Brenda Hoagland, specialist in the topic, clarifies the main doubts about acute infection.
What are the symptoms of acute HIV infection?
Acute HIV infection may or may not be accompanied by symptoms. Approximately half of people infected with HIV develop symptoms soon after infection. Typically, symptoms occur from 5 to 30 days after the initial infection and can last for about two weeks, and may persist for shorter or longer periods.
Symptoms include: fever (usually 38,3 or more); fatigue; swelling of lymph nodes; sore throat; weight loss; muscle aches; Headache; nausea; night sweats; diarrhea; rash
Having these symptoms does not mean that the person has HIV. The same symptoms can occur with flu, mononucleosis (mono), throat infections and other viral diseases.
The most common test is looking for antibodies that the body produces specifically in response to HIV infection (immunoenzymatic assay, EIA, Also known as Elisa). These antibodies may not be present in the blood for several weeks to up to a few months after infection in cases of overexposure, as in general, for the overwhelming majority of infected people the immune window response is up to 30 days for 99% of people and 60 days to the remaining people. Special cases are defined in other texts, whose links are at the end of this article
Rapid HIV tests, done in blood or oral fluids, are antibody tests. Another type of HIV test looks for the virus itself (it is often called HIV RNA or viral load). This test will detect the virus and provide a positive result right after infection (in about five days). It is therefore an important test for diagnosing people newly infected with HIV. (Editor's note: I received divergent information from another source and I encourage caution).
The normal blood test for HIV antibodies (EIA) may have been negative or undetermined for someone with acute HIV infection. However, examination of HIV RNA will have a positive result during acute infection. A negative or undetermined result in a virus antibody test and a positive result in an RNA test strongly suggest acute HIV infection.
