What happens when HIV tests find people with unexpected infections – children with HIV-negative mothers, virgin youth, and sexually active adults with no HIV-positive partner? Governments have responded to unexpected infections in two ways: (a) African governments have ignored them; (b) governments outside Africa have investigated to find and stop healthcare outbreaks.
(a) African governments ignore unexpected HIV infections
Over more than 30 years, newspapers and medical journals have reported only a very small fraction of the millions of unexpected HIV infections people have found over the last 30 years in themselves, loved ones, and friends. Click on country pagers for an account of some of these reported unexpected infections (countries in alphabetical order): Angola, Benin, Botswana, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Congo (Brazzaville), Cote d’Ivoire, Democratic Republic of the Congo, Equatorial Guinea, Eritrea, Ethiopia, Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Lesotho, Liberia, Madagascar, Malawi, Mali, Mauritania, Mozambique, Namibia, Niger, Nigeria, Rwanda, Senegal, Sierra Leone, Somalia, South Africa, South Sudan, Swaziland, Tanzania, Togo, Uganda, Zambia, Zimbabwe.
(b) Governments outside Africa investigate to find and stop HIV outbreaks from unsafe healthcare
Governments outside sub-Saharan Africa have investigated unexplained infections: asking where people received healthcare; tracing and testing others who got healthcare from the same place; finding and fixing mistakes; and telling the public what happened. No country that has investigated unexpected infections to find an HIV outbreak from healthcare has developed a generalized epidemic. These links take you to pages with information and references for HIV healthcare outbreak investigations in 20 countries (listed in alphabetical order): Argentina, Australia, Cambodia, China, Colombia, Denmark, Egypt, India, Kazakhstan, Kyrgyzstan, Libya, Mexico, Pakistan, Romania, Russia, Spain, Tajikistan, the United States, Uzbekistan, and Vietnam. The table below lists 12 investigated and reported outbreaks with >100 HIV infections.
