ABSTRACT

OBJECTIVES: This intervention linked research aimed to reduce prevalence of Neisseria gonorrhoeae (Ng) and Chlamydia trachomatis (Ct) among female sex workers by means of one round of presumptive treatment (PT), and improved prevention and screening services. METHODS: A single round of PT (azithromycin 1 g) was given to all female sex workers reached during a 1 month period of enhanced outreach activity. Routine sexually transmitted infection (STI) screening services were successfully introduced for two groups of unregistered sex workers who work in brothels (BSWs) and on the street (SSWs). No changes were made to existing screening methods for registered sex workers (RSWs) or lower risk guest relations officers (GROs). Cross sectional prevalence of Ng and Ct was measured by PCR on three occasions, and stratified by type of sex work. Ng/Ct prevalence was assessed twice in clients of BSWs. RESULTS: Prevalence of Ng and/or Ct at baseline, 1 month post-PT, and 7 months post-PT was BSWs: 52%, 27%, 23%; SSWs: 41%, 25%, 28%; RSWs: 36%, 26%, 34%; GROs: 20%, 6%, 24%, respectively. Ng/Ct declines 1 month post-PT were significant for all groups. 6 months later prevalence remained low for BSWs (p<0.001), and SSWs (p = 0.05), but had returned to pre-intervention levels for the other groups. Prevalence of Ng/Ct among clients of BSWs declined from 28% early in the intervention to 15% (p = 0.03) 6 months later. CONCLUSIONS: In this commercial sex setting, one round of PT had a short term impact on Ng/Ct prevalence. Longer term maintenance of STI control requires ongoing access to effective preventive and curative services.

ABSTRACT

Reported are the results of an unmatched case-control study to determine the risk factors associated with acquisition of cholera in Manila. Cases were patients admitted to the San Lazaro Hospital between July and September 1989 and whose stools yielded Vibrio cholerae O1 on culture. Controls were patients admitted to the same hospital and who had no history of diarrhoea or of having taken antibiotics during the 3 days prior to admission. Of the 158 cases and 158 controls who had bought food from street vendors, cases were more likely to have bought the following items: pansit (rice noodles with shrimp, meat, and vegetables), mussel soup, spaghetti, fish balls, pig blood coagulated with vinegar, and salty brine shrimp with vegetables. Cases were also more likely to lack piped water at home. An unconditional logistic regression analysis indicated that only pansit (OR = 2.15, 95% CI = 1.32-3.51), mussel soup (OR = 2.29, 95% CI = 1.06-4.95), and the absence of piped water at home (OR = 2.70, 95% CI = 1.63-4.46) remained as risk factors. As control measures we recommend stricter implementation of the food sanitation code and the licensing of street food vendors.
