Data by transmission category have been statistically adjusted to account for missing risk-factor information.
Heterosexual contact with a person known to have, or to be at high risk for, HIV infection.
Hispanics/Latinos can be of any race.
Other includes American Indian/Alaska Native, Asian, Native Hawaiian/other Pacific Islander, and persons who report multiple races.
Due to the large variability of CD4 counts, particularly measured within a short time (a few months) after infection, the accuracy of estimates of the time from HIV infection to diagnosis is less certain when the measured duration of infection is short. Therefore, the first quartiles of the estimated times from HIV infection to diagnosis are considered less reliable and are not reported.
