Rising trends of STIs and HIV infection in Singapore-- a review of epidemiology over the last 10 years (1994 to 2003).
BACKGROUND
This is a review of the epidemiology and trends of sexually transmitted infections (STIs) in Singapore from 1994 to 2003.


METHODS
Data collated for both notifiable and non-notifiable STIs from 1994 to 2003 were analysed. This data consisted of STI notifications from medical practitioners in Singapore as well as from the Department of STI Control clinic itself.


RESULTS
There was a decline in the overall STI incidence in Singapore in the first half of the last decade from 215 cases per 100,000 population (7,200 cases) in 1994 to 162 cases per 100,000 population (6,318 cases) in 1999, followed by an increasing trend in the number of acute STIs (both bacterial and viral) over the past 5 years to 195 cases per 100,000 population (8,175 cases) in 2003 (P <0.001). The incidence of HIV has risen sharply over the last decade whilst that of other viral STIs has not decreased. Singaporeans are becoming sexually active at a younger age, with casual partners constituting the main primary contacts.


CONCLUSIONS
Although there has been a significant decline in the overall incidence of STIs in Singapore over the last decade, a rise in acute STIs over the last 5 years has resulted in the need to identify the causal factors, and to intensify existing as well as develop new STI/HIV prevention programmes for the general population and certain core groups.
