If AIDS only affects 0.002% of the population, why is this advertisement appearing in every national daily newspaper?

Poster (b&w), 'If AIDS only affects 0.002% of the population, why is this advertisement appearing in every national daily newspaper?', giving detailed information about HIV and AIDS, produced by the Health Education Authority, England, c1986-1990.

'If AIDS only affects 0.002% of the population, why is this advertisement appearing in every national daily newspaper?' The question posed by this Health Education Authority cartoon poster outlines the lack of public understanding of the true numbers of AIDS sufferers in the United Kingdom. It was aimed at people who felt AIDS would not affect them. During the late 1980s, over 1000 people died in the UK from AIDS, and 1000 more were affected. However, the poster suggests that for every person with the disease there were 30 people with HIV, the virus that leads to AIDS. As of December 2007, an estimated 77,400 people were living with HIV in the UK. Approximately 20,700 of these were unaware of their infection.
