This article lists the reported and registered HIV/AIDS cases by reporting region. A region may refer to a country or subdivision, national HIV records are often complicated incomplete or even nonexistent. This list is only documented cases, not for estimated cases. Estimated case numbers differ in significant ways: estimates are available for all areas for all years unlike hard records, and estimates attempt to quantify an epidemic in current time, whereas registered/documented cases are behind the curve, they have lag time to detection and represent the past rather than current situation.

Documentation of HIV transmission often present with significant holes and inconsistencies. In the earlier years of the epidemic, especially in Africa, health systems where completely overwhelmed and millions of people died without government recordkeeping, there is little way of knowing how many people contracted HIV, to get around the problem to get the total cumulative number of HIV infections, HIV death data is taken into account in the table below where those living with HIV are summed with those died of HIV for a cumulative HIV infection figure, nevertheless, the data of credible death estimates exist only for the specific years where available. In spite of data quality issues, all these types of data help to create an epidemiological picture.
US CDC has changed reporting standards for AIDS related deaths (again in 2014); HIV case reporting is not uniform among states that also implement their own surveillance. Globally, some 35.3 million are living with HIV/AIDS, World Health Organization (WHO), an estimated 36 million people have died since the first cases were reported in 1981 and 1.6 million people died of HIV/AIDS in 2012. [1] Using WHO statistics, in 2012 the number of people living with HIV was growing at a faster rate (1.98%) than worldwide human population growth (1.1% annual), [2] and the cumulative number of people with HIV is growing at roughly three times faster (3.22%). The costs of treatment is significantly increasing burden on healthcare systems when budgets remain stagnant, causing cutoffs in funding to healthcare providers. [3]
We’re right at that razor edge. Unless you dramatically change the infection rate...the epidemic is actually going to expand rather than shrink. —Deborah Birx, Obama administration global AIDS coordinator [3]
