HIV affects the immune system. Testing a small sample of blood can show the health of the immune system and how much HIV is in the blood. Other tests can look at the health of other parts of the body, which may be affected by HIV or other conditions.

  • Early-capture HIV study allows for characterization of acute infection period

    Acute HIV infection (AHI) contributes significantly to HIV transmission and may be important for intervention strategies seeking to reduce incidence and achieve a functional cure. In a study by the U.S. Military HIV Research Program (MHRP), Walter Reed Army Institute of Research, published in The New England Journal of Medicine, scientists enrolled and intensively followed a cohort of high-risk individuals, tracking their HIV status and characterizing the disease through the acute stages of HIV infection.

  • HIV and drug resistance

    A recent study found more resistance to the antiretroviral medicine tenofovir than had previously been reported, with 20% resistance to tenofovir in patients with treatment failure in Europe and over 50% resistance in patients with treatment failure in sub-Saharan Africa... The study underlines the importance of rapidly identifying treatment failure through routine measurement of viral load suppression—this is the basis of the third pillar of UNAIDS’ 90–90–90 treatment target, that 90% of people accessing HIV treatment have suppressed viral loads.

  • Undetectable & Low-level HIV Viral Replication

    Even people who are adherent to their medication regimens may experience occasional “blips” in their viral loads, experience viral rebound or maintain a steady, if low, viral load above undetectable levels. To understand why some people struggle to achieve or remain undetectable, we spoke with Keith Henry, MD, an HIV specialist at Hennepin County Medical Center who has more than 25 years of experience caring for people with HIV.

  • Could a $34 smartphone device improve HIV diagnosis in Africa?

    A $34 device that plugs into the audio jack of a smartphone was nearly as effective as far more costly diagnostic blood testing equipment in identifying antibodies for HIV and syphilis in a pilot study in Africa, U.S. researchers said on Wednesday.

  • An HIV Doctor Tells You If Undetectable Really Is the New Negative

    Does being undetectable change the way you talk about your HIV status? Can a person who is undetectable stop worrying about transmitting HIV? Joel Gallant, an HIV doctor at Southwest CARE Center in Santa Fe, New Mexico gives his view.

  • Different community HIV testing and counselling approaches reach different populations in rural Africa

    Home- and community-based HIV testing and counselling services can achieve high participation uptake in rural Africa but reach different populations within a community and should be provided, depending on the groups that are being targeted, according to new research published in PLOS Medicine.

  • Sophisticated HIV diagnostics adapted for remote areas

    Diagnosing HIV and other infectious diseases presents unique challenges in remote locations that lack electric power, refrigeration, and appropriately trained health care staff. To address these issues, researchers have developed a low-cost, electricity-free device capable of detecting the DNA of infectious pathogens, including HIV-1.

    Diagnosing HIV and other infectious diseases presents unique challenges in remote locations that lack electric power, refrigeration, and appropriately trained health care staff. To address these issues, researchers funded by the National Institutes of Health have developed a low-cost, electricity-free device capable of detecting the DNA of infectious pathogens, including HIV-1.

  • Unique Health Care Challenges for Older Adults with HIV

    Dr. Meredith Greene, fellow in the Division of Geriatrics at University of California, San Francisco, has spent her career working out how to integrate HIV services and geriatric care. “Traditionally, those areas haven’t overlapped a lot,” she explains—yet as individuals with HIV live longer with increasingly more effective and tolerable HIV therapies, she recognizes the importance of tailoring medical care services for older HIV-positive adults to their unique medical needs.
