Objective-To determine the changing patterns of HIV infection in women
in three units in London. Subjects-Three hundred and fifty seven HIV
seropositive women who have attended outpatient clinics between 1984 a
nd 1992. Methods-A retrospective review of data obtained from a comput
erised database and supplemented by direct inspection of the notes. Re
sults-The number of newly identified women with HIV has risen steadily
over the period of study with a significant shift towards a heterosex
ual mode of transmission. This is a reflection of increasing numbers o
f women from Sub-Saharan Africa rather than a rise in the incidence of
HIV in women born in the UK. Conclusions-The increase in women infect
ed by HIV remains predominantly restricted to women in ''high risk'' g
roups. Although encouraging, our data should be interpreted with cauti
on since it suffers from the inherent bias of selective testing. Safer
sex education and epidemiological surveillance should continue despit
e the apparent low risk to women born in the UK.
