1 December is World AIDS Day, the day that the world is reminded of our fight against HIV, the virus causing AIDS. In 2020, normal delivery of healthcare services has been disrupted because of COVID-19 pandemic and the corresponding social distancing and other regulations. Provision and utilization of HIV testing service have also been affected. Areas highlighted in darker colours on the map refer to places with low awareness of HIV in 2020. In a number of countries, less than 50% of people living with HIV knew their status.
HIV infection may be asymptomatic or mildly symptomatic in the initial phase. Some infected people may not be diagnosed until they develop serious complications. Late HIV diagnosis commonly refers to cases with CD4 count below 350/uL or with AIDS at the time of diagnosis. Compared to people with early diagnosis, those with late diagnosis would have relatively poorer treatment effect and higher mortality rate. From the public health perspective, late diagnosis may also imply posing an increased risk of onward community transmission during the prolonged undiagnosed period. Countries with over half of their HIV cases diagnosed late are labelled with yellow or red circles on the map.
If exposure to HIV is suspected, or if there have been high risk exposure, get tested as soon as possible for timely treatment initiation.
