World AIDS Day 2020: Global solidarity, resilient services

▴ World AIDS Day 2020: Global solidarity, resilient services
We can all contribute to the effort to end AIDS and make the world a healthier place.

     The world has made significant progress since the late 1990s, but HIV remains a major global public health issue. And like many other major health issues, it faces additional challenges during the COVID-19 pandemic. There were an estimated 38.0 million people living with HIV at the end of 2019.

 

On 1 December WHO joins partners in paying tribute to all those working to provide HIV services, and in calling on global leaders and citizens to rally for “global solidarity” to maintain essential HIV services during COVID 19 and beyond. It is a call to focus on vulnerable groups who are already at risk and expand coverage to children and adolescents. 

And in 2020, the International Year of the Nurse and the Midwife, it is a call for more protection and support to these health workers who have long been on the frontline of HIV service delivery.  

 WHO defines key populations as people in populations who are at increased HIV risk in all countries and regions, which include:

  • Men who have sex with men
  • People who inject drugs
  • People in prisons and other closed settings
  • Sex workers and their clients
  • Transgender

 

In addition, given their life circumstances, a range of other populations may be particularly vulnerable, and an increased risk of HIV infection, such as adolescent girls and young women in southern and eastern Africa and indigenous peoples in some communities.

 

Increased HIV vulnerability is often associated with legal and social factors, which increases exposure to risk situations and creates barriers to accessing effective, quality, and affordable HIV prevention, testing and treatment services.

 

HIV continues to be a major global public health issue, having claimed almost 33 million lives so far. However, with increasing access to effective HIV prevention, diagnosis, treatment and care, including for opportunistic infections, HIV infection has become a manageable chronic health condition, enabling people living with HIV to lead long and healthy lives. However, not everyone is able to access HIV testing, treatment and care. Global targets for 2020 are at risk of being missed unless rapid action is taken.

 

Risk factors

Behaviors and conditions that put individuals at greater risk of contracting HIV include:

  • Having unprotected anal or vaginal sex;
  • Having another sexually transmitted infection (STI) such as syphilis, herpes, Chlamydia, gonorrhea, and bacterial vaginosis;
  • Sharing contaminated needles, syringes, and other injecting equipment and drug solutions when injecting drugs;
  • Receiving unsafe injections, blood transfusions and tissue transplantation, and medical procedures that involve unsterile cutting or piercing; and
  • Experiencing accidental needle stick injuries, including among health workers

 

Transmission

HIV can be transmitted via the exchange of a variety of body fluids from infected people, such as blood, breast milk, semen and vaginal secretions. HIV can also be transmitted from a mother to her child during pregnancy and delivery. Individuals cannot become infected through ordinary day-to-day contact such as kissing, hugging, shaking hands, or sharing personal objects, food or water. 

It is important to note that people with HIV who are taking ART and are virally suppressed do not transmit HIV to their sexual partners.  Early access to ART and support to remain on treatment is therefore critical not only to improve the health of people with HIV but also to prevent HIV transmission.

 

Signs and symptoms

The symptoms of HIV vary depending on the stage of infection:

  • Weakened immune system
  • Swollen lymph nodes
  • Weight loss
  • Fever
  • Diarrhea
  • Cough
  • Tuberculosis (TB)
  • Cryptococcal meningitis
  • Severe bacterial infections
  • Cancers such as lymphomas and Kaposi's sarcoma.

 

Treatment

There is no cure for HIV infection. However, effective antiretroviral drugs (ARVs) can control the virus and help prevent onward transmission to other people.

At the end of 2019, an estimated:

  • 81% of people living with HIV knew their status
  • 67% were receiving antiretroviral therapy (ART)
  • 59% had achieved suppression of the HIV virus with no risk of infecting others
  • 4 million people were accessing antiretroviral therapy
  • New HIV infections fell by 39%
  • HIV-related deaths fell by 51%
  • 3 million lives saved due to ART

This achievement was the result of great efforts by national HIV programmes supported by civil society and international development partners.

 

Prevention

Individuals can reduce the risk of HIV infection by limiting exposure to risk factors. Key approaches for HIV prevention, which are often used in combination, are listed below.

  • Male and female condom use

Correct and consistent use of male and female condoms during vaginal or anal penetration can protect against the spread of STIs, including HIV. Evidence shows that male latex condoms when used consistently have an 85% or greater protective effect against HIV and other STIs.

  • Testing and counseling for HIV and STIs

Testing for HIV and other STIs is strongly advised for all people exposed to any of the risk factors.

  • Testing and counseling, linkages to tuberculosis (TB) care

TB is the most common illness among people living with HIV. Early detection of TB and prompt linkage to TB treatment and ART can prevent these deaths.

  • Voluntary medical male circumcision (VMMC)

Medical male circumcision reduces the risk of heterosexually acquired HIV infection in men by approximately 50%

  • Harm reduction for people who inject and use drugs

People who inject drugs can take precautions against becoming infected with HIV by using sterile injecting equipment (including needles and syringes) for each injection, and not sharing drug-using equipment and drug solutions.

 

WHO response

The Sixty-Ninth World Health Assembly endorsed a new “Global health sector strategy on HIV for 2016–2021”. The strategy includes five strategic directions that guide priority actions by countries and by WHO over six years.

The strategic directions are:

  • Information for focused action (know your epidemic and response)
  • Interventions for impact (covering the range of services needed)
  • Delivering for equity (covering the populations in need of services)
  • Financing for sustainability (covering the costs of services)
  • Innovation for acceleration (looking towards the future).
  • WHO is a cosponsor of the Joint United Nations Programme on AIDS (UNAIDS). Within UNAIDS, WHO leads activities on HIV treatment and care, and HIV and TB co infection, and jointly coordinates the work on elimination of MTCT of HIV with UNICEF.
