More than 6.2 million of South Africa's 47 million people may be HIV-positive, a dramatic increase from last year's estimate.
The department of health on Monday said that between 6.29 and 6.57 million South Africans are infected with the HIV virus.
The figures contradict a study by Statistics South Africa, a state agency, which estimated in May that about 4.5 million South Africans were infected with HIV. That figure put South Africa behind India as the country with the highest number of infections.
