[HIV infected women in Copenhagen. Risk factors and sex behavior].

A total of 115 women were found to be HIV-antibody positive during the period January 1985 to September 1988 in the three large hospitals in Copenhagen. Thirty-five women (31%) had been infected heterosexually, 63 (55%) were intravenous drug addicts, 12 (10%) had been infected by transfusion and in five (4%) the mode of transmission was unknown. In 1988, 73% of the women who were found to be HIV-positive were infected heterosexually while only 14% were infected in this manner in 1985. Out of the heterosexually HIV-infected women, 25 (71%) had probably been infected by a man from a risk group while nine further women were infected by a known HIV-positive man with-out connection to any risk group. Eleven women (31%) stated that they practised "safe sex" prior to the HIV test while 22 (74%) did so after the positive HIV-test, which represents a considerable improvement. Out of the drug addicted women, six (10%) stated that they had always practiced "safe sex" prior to the test while 13 (28%) did so after the HIV-test. Approximately 1/3 of these women periodically shared syringes and needles with others. It is concluded that heterosexual contact among HIV-infected women in Copenhagen is a route of transmission of significance. Women infected heterosexually appear to alter their sexual behavior when they are made aware of the positive HIV-test.
