Risk by Age Group

In the United States, HIV is spread mainly through anal or vaginal sex or by sharing drug-use equipment with an infected person.

Young gay and bisexual men, for example, have been especially hard-hit by HIV, though we have seen progress among this group in recent years. Find out more about prevention challenges for these groups and what CDC is doing to address them.
