Notes:
a
Individuals can contribute to more than one category as they age or their HIV status changes during follow-up.
b
We report the HIV status information as it is known to the study and may not be the same as men and women's knowledge of their own HIV status. Unknown HIV status includes all the persons-years of exposure before the start of the HIV surveillance as well as individual time prior to the first HIV test, and exposure time more than five years after the last HIV negative test.
c
The death rate for adult HIV negatives is higher than for the population as a whole, which is due to the older age distribution of the population with a known HIV negative status (appendix, pp. 2-3).
