World AIDS Day is observed on December 1st every year to raise awareness about HIV/AIDS and to remember those who have lost their lives to the disease.

The theme for World AIDS Day 2021 is 'End Inequalities, End AIDS', which focuses on addressing the disparities in access to healthcare and treatment for people living with HIV/AIDS.

According to UNAIDS, there were 38 million people living with HIV/AIDS globally in 2019, and 690,000 people died from AIDS-related illnesses.

Prevention and early diagnosis are crucial in the fight against HIV/AIDS. This includes practicing safe sex, getting tested regularly, and using pre-exposure prophylaxis (PrEP) for those at high risk of contracting HIV.

Stigma and discrimination against people living with HIV/AIDS remain a significant barrier to treatment and care. World AIDS Day aims to reduce this stigma and promote acceptance and understanding.

World AIDS Day is observed globally through events, campaigns, and educational activities to raise awareness about HIV/AIDS and to promote prevention, testing, and treatment.
