Current HIV/AIDS treatments, particularly antiretroviral therapy (ART), can effectively suppress the virus, manage symptoms, and significantly improve quality of life and life expectancy. However, these treatments cannot completely cure HIV - the virus remains in the body and can rebound if treatment is stopped.

HIV (Human Immunodeficiency Virus) is the virus that attacks the immune system, while AIDS (Acquired Immunodeficiency Syndrome) is the late stage of HIV infection that occurs when the immune system is severely damaged. A person can live with HIV for many years without developing AIDS, especially with proper treatment.

HIV is transmitted through direct contact with infected blood, semen, vaginal fluids, or breast milk. Casual contact like shaking hands, hugging, sharing toilets, or being near coughing/sneezing cannot transmit HIV. However, activities involving blood contact like caring for nosebleeds or open-mouth kissing when blood is present can transmit the virus.

The World AIDS Day theme for 2010 was 'Universal Access and Human Rights,' emphasizing the importance of ensuring universal access to HIV prevention, treatment, care, and support while protecting human rights.

Tata Consultancy Services (TCS) established 'Club Red: Let's Talk' as their corporate initiative to raise HIV/AIDS awareness among employees.

Mosquitoes cannot transmit HIV. When a mosquito bites someone, it injects its own saliva, not blood from the previous person. HIV cannot survive in mosquitoes' digestive systems - the virus is broken down as food. The mouth parts of mosquitoes are also too small to contain enough HIV particles to cause infection.

HIV is transmitted through bodily fluids containing high concentrations of the virus. Blood, semen, vaginal fluid, preseminal fluid, and breast milk are all established transmission routes. Saliva, tears, and sweat are NOT transmission routes.
