The increase in heterosexual infection
The annual figures for HIV infections, published recently, show an alarming trend. Homosexually acquired infections have been relatively stable for ten years (they are now at about 1700 a year). However, heterosexually acquired HIV has increased by a factor of five from about 700 in 1994 to 3,800 in 2003.
Infection acquired overseas
The increase has been particularly sharp since 1999, much of it due to imported infections. In 2003 about 90% of newly diagnosed heterosexual infections were thought to have been acquired overseas, mostly in Africa. Of the 35,500 patients seen for care in that year 15,600 (44%) had been exposed to heterosexual infection in Africa.
South East Africa
Three countries Malawi, Zambia and Zimbabwe accounted for about 1500 cases in each of the last two years. This was about a quarter of all new infections in the UK.
According to Professor Pat Troop, Chief Executive of the Health Protection Agency "Each HIV infection prevented can save between 500,000 and 1million in treatment and lost productivity " Taking the lower figure gives the cost of infection, just from these three countries as 750 million a year. The governments response so far is to increase funding for all Sexually Transmitted Diseases by 100m a year for three years.
Immigration from South East Africa
