21 HIV positive women have given birth at UllevÃ¥l Hospital. Initially this category consisted of drug addicts infected by hypodermic needles, but in the last few years, most of the women were infected heterosexually. Maternity check-ups should be performed in cooperation with internists. Because of the danger of reduced immunity, test cultures should be taken from the cervix, and blood should be tested for antibodies against different viruses and toxoplasmosis. An ultrasound examination in addition to the one performed as a routine in Norway should be performed towards the end of the pregnancy, to monitor foetal growth. The average length of pregnancy was 39 weeks. Five infants were delivered by Caesarean section, while 16 infants were delivered vaginally. All the infants were in good condition after delivery, but the average length and weight were below normal.
