This quiz is not there to catch you out: it is there to spot ideas that have aged. Much of what people believe about these infections comes from 1990s campaigns, and two things have changed since — HIV treatment, which removes transmission, and testing, now simple and often free.
After each answer the correction comes straight away, with a link to the page that goes further.
A multiple-choice quiz: pick one answer to each question, the correction appears right away and your score at the end.
Three things to keep
Effective treatment removes HIV transmission. It is the most important change of the past twenty years, and the least known.
Most of these infections cannot be seen. The only way to know is a test, and the only useful moment is after the window period.
Two of them are preventable by vaccine — hepatitis B and HPV — and a third has an emergency treatment in the hours after exposure.
