Hiv incubation exposure-Stages of HIV Infection | HIV Risk Reduction Tool | CDC

Individual data on HIVinfected individuals from 15 countries were collated, checked, and analysed centrally. We calculated estimates of mortality and AIDS incidence rates and estimated the proportions of individuals surviving and developing AIDS at each year after seroconversion from the numbers of observed deaths or cases of AIDS and the corresponding person-years at risk. Analyses were adjusted for age at seroconversion, time since seroconversion, and other factors as appropriate. Median survival varied from There was no appreciable effect of exposure category on survival.

What can increase HIV risk? What can decrease HIV risk? What are the best ways to decrease my chances of getting or transmitting HIV? When people get HIV and don't receive treatment, they will typically progress through three stages of disease. Medicine to treat HIV , known as antiretroviral therapy ART , helps people at all stages of the disease if taken the right way, every day, and treatment can slow or prevent progression from one stage to the next.

Treatment can also dramatically reduce the chance of transmitting HIV. CD4 cells activate the body's immune system to fight off infections. HIV attacks the body's CD4 cells so that the immune system is less able to fight off viruses or infections.

Opportunistic illnesses are infections and infection-related cancers that are more common or more severe in people with HIV because their immune systems are damaged.

Examples include Kaposi's sarcoma, lymphoma, tuberculosis, and pneumonia. More information on opportunistic infections and AIDS-related cancers can be found here. Without treatment, people with AIDS typically survive about 3 years. Common symptoms of AIDS include chills, fever, sweats, swollen lymph glands, weakness, and weight loss. People with AIDS can have a high viral load and be very infectious. I am looking for information for someone who is M Male.

Update Settings. Toggle navigation. Stages of HIV Infection. This is the body's natural response to infection. When people have acute HIV infection, they have a large amount of virus in their blood and are very contagious. But people with acute infection are often unaware that they're infected because they may not feel sick right away or at all. To know whether someone has acute infection, either a fourth-generation or nucleic acid NAT test is necessary. If you think you have been medicines to prevent or treat HIV.

This can also occur when sharing needles or works, including cottons, cookers, or rinse water. During this phase, HIV is still active but reproduces at very low levels. People may not have any symptoms or get sick during this time. For people who aren't taking medicine to treat HIV, this period can last a decade or longer, but some may progress through this phase faster. People who are taking ART the right way, every day, may be in this stage for several decades. It's important to remember that you can still transmit HIV to others during this phase, although people who are on ART and stay virally suppressed are much less likely to transmit HIV than people who are not virally suppressed.

At the end of this phase, your viral load starts to go up and your CD4 cell count begins to go down.

For many conditions, incubation periods are longer in adults than they are in children or infants. What is Tenofovir? How can testing help me? Gonorrhea has an incubation period of only days , so you can get tested for it shortly after exposure. If you do not have medical insurance, some testing sites may offer free tests. Have you been diagnosed with or sought treatment for another sexually transmitted disease?

A Timeline of HIV Symptoms: How Does It Progress?

In the virus that caused AIDS was discovered by scientists in France and the routes of transmission were confirmed. The virus eventually became known as the human immunodeficiency virus HIV. There are 2 different types of HIV:.

HIV infection affects the immune system. The immune system is the body's defense against infections by microorganisms such as very small bacteria or viruses that get past the skin and mucous membranes and cause disease. The immune system produces special cells called antibodies to fight off or kill these microorganisms.

A special weakness of the immune system is called an immunodeficiency. Human immunodeficiency virus HIV infects, and eventually destroys, special cells in the immune system called lymphocytes and monocytes.

This slowly leads to a persistent, progressive and profound impairment of the immune system, making an individual susceptible to infections and conditions such as cancer. HIV is the beginning stage of infection and can be detected by a blood test described in this Fact Sheet.

When the immune system becomes very affected, the illness progresses to AIDS. Blood tests described in this Fact Sheet , or the appearance of certain infections, indicate that the infection has progressed to AIDS.

Sexual intercourse vaginal, anal and oral or through contact with infected blood, semen, or cervical and vaginal fluids. This is the most frequent mode of transmission of HIV world wide, and can be transmitted from any infected person to his or her sexual partner man to woman, woman to man, man to man and, but less likely, woman to woman. The presence of other sexually transmitted diseases STDs especially those causing genital ulcers increase the risk of HIV transmission because more mucous membrane is exposed to the virus.

Blood transfusion or transfusion of blood products eg. Injecting equipment such as needles or syringes, or skin-piercing equipment, contaminated with HIV.

HIV infected persons develop antibodies to HIV antigens usually 6 weeks to 3 months after being infected. In some individuals, the test for the presence of these antigens may not be positive until 6 months or longer although this would be considered unusual.

This time -- during which people can be highly infectious and yet unaware of their condition -- is known as the "the window period". Some people have a "glandular fever" like illness fever, rash, joint pains and enlarged lymph nodes at the time of seroconversion. Occasionally acute infections of the nervous system eg. A person infected with HIV may have no symptoms for up to 10 years or more.

The vast majority of HIV-infected children are infected in the peri-natal period, that is, during pregnancy and childbirth. The period without symptoms is shorter in children, with only a few infants becoming ill in the first few weeks of life. Most children start to become ill before 2 years; however, a few remain well for several years.

This progression depends on the type and strain of the virus and certain host characteristics. Factors that may cause faster progression include age less than 5 years, or over 40 years, other infections, and possibly genetic hereditary factors.

HIV infects both the central and the peripheral nervous system early in the course of infection. This causes a variety of neurological and neuropsychiatric conditions.

As HIV infection progresses and immunity declines, people become more susceptible to opportunistic infections. These include:. Any blood test used to detect HIV infection must have a high degree of sensitivity the probability that the test will be positive if the patient is infected and specificity the probability that the test will be negative if the patient is uninfected. Therefore, if available, all positive test results should be confirmed by retesting, preferably by a different test method.

HIV antibody tests usually become positive within 3 months of the individual being infected with the virus the window period. In some individuals, the test may not be positive until 6 months or longer considered unusual. In some countries, home testing kits are available.

Although these tests are very sensitive, there is a "window period. In the case of the most sensitive anti-HIV tests currently recommended, the window period is about three weeks. This period may be longer if less sensitive tests are used.

Screening of donated blood accounts for the majority of HIV tests performed worldwide. More recently, people have been encouraged to attend voluntary counselling and testing VCT services to find out their HIV status.

It is hoped that if people know their HIV status and are seronegative, they will adopt preventive measures to prevent future infection see Fact Sheet Recent advances in technology have lead to various simple rapid tests being developed.

Most of these tests come in a kit and require no reagent, equipment, training, or specified temperature controls, and tests can be performed at any time. With these rapid tests, people can wait for their results. Although the costs of these simple rapid tests are higher than ELISA they will be useful in STD clinics, antenatal clinics, and counselling centres, because of the ease of use.

In some countries, home testing kits are also available. These tests are not very reliable, and support such as pre and post test counselling is not available. False positive result HIV tests have been developed to be especially sensitive and, consequently, a positive result will sometimes be obtained even when there are no HIV antibodies in the blood. This is known as a false positive, and because of this, all positive results must be confirmed by another test method.

A confirmed positive result from the second test method means that the individual is infected with HIV. False negative result A false negative result occurs when the blood tested gives a negative result for HIV antibodies when in fact the person is infected, and the result should have been positive.

The likelihood of a false negative test result must be discussed with patients if their history suggests that they have engaged in behaviour which was likely to put them at risk of HIV infection.

In this situation, repeated testing over time may be necessary before they can be reassured that they are not infected with HIV. The most frequent reason for a false negative test result is that the individual is newly infected ie. However, it is important to remember that someone who has tested negative because they are not infected with HIV can become infected the following day! All people taking an HIV test must give informed consent prior to being tested.

The results of the test must be kept absolutely confidential. However, shared confidentiality is encouraged. Shared confidentiality refers to confidentiality that is shared with others. These others might include family members, loved ones, care givers, and trusted friends.

This shared confidentiality is at the discretion of the person who will be tested. Although the result of the HIV test should be kept confidential, other professionals such as counsellors and health and social service workers, might also need to be aware of the person's HIV status in order to provide appropriate care. HIV can be transmitted by:. The three main objectives for which HIV antibody testing is performed are:.

Questions for Reflection and Discussion. Handshakes Work or school contact Using telephones Swimming pools Sharing cups, glasses, plates, and other utensils. Tuberculosis Other sexually transmitted diseases Septicaemia Pneumonia usually pneumocystis carinii Recurrent fungal infections of the skin, mouth and throat Unexplained fever Meningitis.

Other Conditions:. Other skin diseases Chronic diarrhoea with weight loss often known as "slim disease" Other diseases such as cancers eg. Kaposi sarcoma. Why is it important to understand the danger of HIV transmission during the "window period"? Why is informed consent essential?

What are the dangers of receiving a false negative result? What should be done if a person's test is sero-negative? World Health Organization Standard treatments and essential drugs for HIV-related conditions.
