Worldwide, a total of about 84% of all HIV-positive people know their virus carrier status. This means that about 16% are not aware of their status. However, there are significant regional differences. For example, the information gap, i.e. the number of people who do not know that they are infected with HIV, is much higher in the Middle East, North Africa, Eastern Europe and Central Asia than in Central Europe and North America.
In addition, about 95% of those over 55 know that they are living with HIV, while this is only true of about 56% of 13- to 14-year-olds. The differences are therefore not only regional, but also age-dependent.
Even in the 21st century, barriers still exist that can make it difficult for those affected to get tested for HIV. Stigma, for example, or discrimination play an important role. In many parts of the world, access to medical care is also limited.
In many cases, this leads to a late diagnosis, which can be associated with an increased risk of complications and a more severe course of the disease. But it is not only the person affected who is exposed to a higher risk: The longer an HIV case remains undiagnosed, the more likely the patient is to infect other people.
The WHO has therefore issued new recommendations aimed at reaching more infected people and enabling rapid therapies:
The WHO recommendations to close the information gap aim to reach all people who are unaware of their infection status. They allow for efficient and resource-oriented interventions that overcome the known barriers.
