Data are n (%) unless otherwise stated. Note that demographic groups are not mutually exclusive. When reporting cases, country officials have the ability to report more than one mode of transmission. The denominators used for the percentage calculations are the totals in the far right column. The most common form of transmission was sexual encounter, with markedly higher rates in men, men who have sex with men, and individuals aged 18–49 years.
