Key approaches for HIV prevention, which are often used in combination, include: male and female condom use; testing and counselling for HIV and STIs; testing and counselling for linkages to tuberculosis (TB) care; voluntary medical male circumcision (VMMC); use of antiretroviral drugs (ARVs) for prevention;
How does HIV treatment work?
HIV disease can be managed by treatment regimens composed of a combination of three or more antiretroviral (ARV) drugs. Current antiretroviral therapy (ART) does not cure HIV infection but highly suppresses viral replication within a person's body and allows an individual's immune system recovery to strengthen and regain the capacity to fight off opportunistic infections and some cancers.
How long does it take for HIV to show symptoms?
The symptoms of HIV vary depending on the stage of infection. Though people living with HIV tend to be most infectious in the first few months after being infected, many are unaware of their status until the later stages. In the first few weeks after initial infection people may experience no symptoms or an influenza-like illness including fever, headache, rash or sore throat.
What is the most advanced stage of HIV?
The most advanced stage of HIV infection is acquired immunodeficiency syndrome (AIDS), which can take many years to develop if not treated, depending on the individual. AIDS is defined by the development of certain cancers, infections or other severe long-term clinical manifestations.

How long does it take for a person to develop antibodies to HIV?
In most cases, people develop antibodies to HIV within 28 days of infection.
How does treatment help prevent HIV?
Having an undetectable viral load may also help prevent transmission from injection drug use.
Why is it important to take HIV medication?
Taking HIV medication consistently, as prescribed, helps prevent drug resistance. Drug resistance develops when people with HIV are inconsistent with taking their HIV medication as prescribed. The virus can change (mutate) and will no longer respond to certain HIV medication. If you develop drug resistance, it will limit your options ...
What does it mean when your HIV is suppressed?
Viral suppression is defined as having less than 200 copies of HIV per milliliter of blood. HIV medicine can make the viral load so low that a test can’t detect it (called an undetectable viral load ). If your viral load goes down after starting HIV treatment, that means treatment is working.
What is the amount of HIV in the blood called?
The amount of HIV in the blood is called viral load . Taking your HIV medicine as prescribed will help keep your viral load low and your CD4 cell count high. HIV medicine can make the viral load very low (called viral suppression ). Viral suppression is defined as having less than 200 copies of HIV per milliliter of blood.
What does it mean when your viral load goes down after HIV treatment?
If your viral load goes down after starting HIV treatment, that means treatment is working. Continue to take your medicine as prescribed.
How long does it take for a mother to give her baby HIV?
If a mother with HIV takes HIV medicine as prescribed throughout pregnancy, labor, and delivery and gives HIV medicine to her baby for 4 to 6 weeks after birth, the risk of transmitting HIV to her baby can be 1% or less.
How long does it take to get rid of HIV?
There is no effective cure for HIV. But with proper medical care, you can control HIV. Most people can get the virus under control within six months. Taking HIV medicine does not prevent transmission ...
When should HIV testing be performed?
Testing for HIV should be performed at the time of STI diagnosis and treatment if not performed at the initial STI evaluation and screening ( 82, 195, 416 ).
When should a woman be tested for HIV?
All pregnant women should be tested for HIV during the first prenatal visit. A second test during the third trimester, preferably at <36 weeks’ gestation, should be considered and is recommended for women who are at high risk for acquiring HIV, women who receive health care in jurisdictions with high rates of HIV infection, and women served in clinical settings in which prenatal screening identifies ≥1 pregnant woman with HIV per 1,000 women screened ( 138 ). Diagnostic algorithms for HIV for pregnant women do not differ from those for nonpregnant women (see STI Detection Among Special Populations). Pregnant women should be informed that HIV testing will be performed as part of the routine panel of prenatal tests ( 138 ); for women who decline HIV testing, providers should address concerns that pose obstacles, discuss the benefits of testing (e.g., early HIV detection, treatment, and care for improving health of the mother and reducing perinatal transmission of HIV), and encourage testing at subsequent prenatal visits. Women who decline testing because they have had a previous negative HIV test result should be informed about the importance of retesting during each pregnancy. Women with no prenatal care should be tested for HIV at the time of delivery.
What is a sexual health clinic?
STD specialty or sexual health clinics are a vital partner in reducing HIV infections in the United States. These clinics provide safety net services to vulnerable populations in need of HIV prevention services who are not served by the health care system and HIV partner service organizations. Diagnosis of an STI is a biomarker for HIV acquisition, especially among persons with primary or secondary syphilis or, among MSM, rectal gonorrhea or chlamydia ( 197 ). STD clinics perform only approximately 20% of all federally funded HIV tests nationally but identify approximately 30% of all new infections ( 414 ). Among testing venues, STD clinics are high performing in terms of linkage to HIV care within 90 days of diagnosis; during 2013–2017, the percentage of persons with a new diagnosis in an STD clinic and linked to care within 90 days increased from 55% to >90% ( 415, 415 ).
How to diagnose HIV?
HIV infection can be diagnosed by HIV 1/2 Ag/Ab combination immunoassays. All FDA-cleared HIV tests are highly sensitive and specific. Available serologic tests can detect all known subtypes of HIV-1. The majority also detect HIV-2 and uncommon variants of HIV-1 (e.g., group O and group N).
What test is used to test for HIV?
According to an algorithm for HIV diagnosis, CDC recommends that HIV testing begin with a laboratory-based HIV-1/HIV-2 Ag/Ab combination assay, which, if repeatedly reactive, is followed by a laboratory-based assay with a supplemental HIV-1/HIV-2 antibody differentiation assay ( https://stacks.cdc.gov/view/cdc/50872 ). This algorithm confers an additional advantage because it can detect HIV-2 antibodies after the initial immunoassay. Although HIV-2 is uncommon in the United States, accurate identification is vital because monitoring and therapy for HIV-2 differs from that for HIV-1 ( 420 ). RNA testing should be performed on all specimens with reactive immunoassay but negative supplemental antibody test results to determine whether the discordance represents acute HIV infection.
What are the challenges of HIV?
They face multiple adaptive challenges, including coping with the reactions of others to a stigmatizing illness, developing and adopting strategies to maintain physical and emotional health, initiating changes in behavior to prevent HIV transmission to others, and reducing the risk for acquiring additional STIs. Many persons will require assistance gaining access to health care and other support services and coping with changes in personal relationships.
What is the first test for HIV?
Providers should use a laboratory-based antigen/antibody (Ag/Ab) combination assay as the first test for HIV, unless persons are unlikely to follow up with a provider to receive their HIV test results; in those cases screening with a rapid POC test can be useful.
