Madziva- Anoziva and Anotida Chikonyora are one-year old identical twins, born to a discordant couple (in which one person is HIV positive and the other is not) in Centenary, about 120 kilometres north of the capital of Harare. Smiling in the comforting hands of their parents, the twins have both tested negative for HIV - thanks to the government supported elimination of new HIV infections among children.
