acquired immunodeficiency syndrome (aids)

The full form of AIDS is Acquired Immuno Deficiency Syndrome. It is the advanced stage of the infection caused by Human Immuno Deficiency Virus (HIV). It can damage the immune system of an HIV infected person. AIDS was identified in 1981 when the virus was transferred from chimpanzees to human beings in central Africa. AIDS has no universal cure or treatment but Anti Retroviral Therapy or ART can suppress the virus to an 'undetectable level'. This can lead to the prevention of sexual transmission of HIV. Surprisingly, a few individuals such as a patient in Berlin Timothy Ray Brown was the 1st person in the world to be cured of AIDS through the stem cell transplant.

Causes of Acquired Immunodeficiency Syndrome

S.No. Causes Explanation
1 HIV infection
  • AIDS occurs only after infection with Human Immunodeficiency Virus (HIV).
  • The virus attacks CD4 (T-helper) cells and weakens the immunity.
2 Untreated or late diagnosis of HIV
  • HIV may multiply exponentially over the years if the virus is not detected and treated at an early stage.
  • It can further destroy the immune system and lead to AIDS.
3 Lack of Antiretroviral Therapy (ART)
  • In case of irregular treatment, the viral load rises and CD4 counts get reduced.
  • It fastens the progression to AIDS.
4 High viral load
  • It means the infected individual contains more than 1,00,000 copies of the virus.
  • It shows that the virus is multiplying quickly.
5 Co-infections (TB and Hepatitis)
  • The existing infection may further weaken immunity and rapidly cause AIDS.
6 Poor nutrition & weak health
  • Malnutrition and poor health reduces the ability of the body to fight infections and raises the risk of AIDS.
7 Stigma & lack of awareness
  • The misinformation and fear can delay the testing and treatment of the disease. Many individuals show up at an advanced stage of AIDS.

HIV Symptoms in Men

Among the men, an early exposure to HIV infection may cause symptoms of flu for about 2 to 4 weeks. It can further lead to fever, sore throat, rashes, fatigue, muscle pain and sweating at night. Few men may also experience mouth or genital ulcer. The weight loss, chronic diarrhoea, fever for a long time, infections such as TB, pneumonia, fungal infection. Men may suffer from swollen glands, high tiredness and reduced hunger. At the advanced stage of AIDS, the immune system is badly damaged. Men can become vulnerable to opportunistic infections such as pneumonia, brain infection, and cancer. The opportunistic infection is an illness caused by germs that do not harm the good immune system but may cause severe damage to the health when the immune system becomes weak. Further, the neurological symptoms such as memory loss, doubt or confusion and weakness can also appear. The testing for HIV at an early stage and Anti Retroviral Therapy (ART) may prevent these symptoms and can reduce the chances of AIDS.

Important Government Initiatives

S.No. Initiatives Important Features
1 National AIDS and STD Control Programme (NACP) - Phase V (2021 to 26)
  • This is a central sector scheme and aims at 80% reduction in new HIV infections and AIDS-related deaths.
  • It focuses on high-risk groups, integrated testing, treatment and dual elimination of HIV & syphilis.
2 Test and Treat Policy
  • The policy mentions that all HIV-positive persons are offered free lifelong ART immediately after diagnosis to suppress viral load and prevent serious illness.
3 HIV or AIDS (Prevention and Control) Act, 2017
  • It is a legal framework to prevent discrimination, protect rights of people with HIV, ensure confidentiality and promote access to prevention, testing and treatment services.
4 Targeted Interventions (TIs)
  • The programmes focused on high-risk groups such as migrants, transgender.
5 Prevention of Parent-to-Child Transmission (PPTCT)
  • The regular HIV testing of pregnant women, ART for mother and infant, and adoption of safe delivery or feeding practices to eliminate vertical transmission of the virus.
6 Mission Sampark & Community based Screening
  • It traces and reconnects people with HIV who have stopped their Antiretroviral therapy.

Preventions of AIDS

AIDS can be prevented by stopping or breaking the transmission of Human Immune Deficiency Virus (HIV). This can be done by an early diagnosis and beginning of the treatment. The important prevention measures are regular and appropriate use of protection during sexual activity and avoiding high risk sexual practices. There should be more use of sterile needles and syringes. The blood required for blood transfusion must be tested and checked properly for HIV. The Pre-exposure prophylaxis or PrEP for high risk HIV negative people and post-exposure prophylaxis or PEP within 72 hours after exposure to HIV, can reduce the risk of infection. The pregnant women must take regular HIV testing. In case they are found to be positive then the ART for mother and child can prevent mother-to-child transmission.

National AIDS Control Programme (NACP)

It is the flagship programme in India and implemented by the National AIDS Control Organization (NACO) under the Ministry of Health and Family Welfare. The programme prevents and controls HIV or AIDS and sexually transmitted infections.The programme is in phase V (2021 to 2026) and aims for the reduction of about 80% in new HIV infections and AIDS related deaths. This initiative prioritizes the high risk groups and integrates the prevention, testing, treatment, care and other support services. It includes test and treat, universal monitoring of Viral Load. Targeted Interventions (TIs), PPTCT, community based screening, Mission Sampark for lost patient tracing and transition to dolutegravir-based Anti Retroviral therapy (ART) recommended by the World Health Organization (WHO). The NACP also trains health workers and promotes the HIV or AIDS (Prevention and Control) Act of 2017 and helps in reducing the stigma. It ensures that the individual with HIV can access services with dignity and live a near-normal life span or expectancy.
