Mass vaccination with a two-dose oral cholera vaccine in a refugee camp.
In refugee settings, the use of cholera vaccines is controversial since a mass vaccination campaign might disrupt other priority interventions. We therefore conducted a study to assess the feasibility of such a campaign using a two-dose oral cholera vaccine in a refugee camp. The campaign, using killed whole-cell/recombinant B-subunit cholera vaccine, was carried out in October 1997 among 44,000 south Sudanese refugees in Uganda. ⋯ Mass vaccination of a large refugee population with an oral cholera vaccine therefore proved to be feasible. A pre-emptive vaccination strategy could be considered in stable refugee settings and in urban slums in high-risk areas. However, the potential cost of the vaccine and the absence of quickly accessible stockpiles are major drawbacks for its large-scale use.

Major public health resources are devoted to the prevention of sexually transmitted diseases (STDs) through public STD clinics. However, little is known about where people actually receive treatment for STDs. ⋯ The health care utilization patterns for STD treatment in the United States are complex. Specific disease diagnosis, gender, race and income status all affect where people will seek treatment. These factors need to be taken into account when STD prevention strategies are being developed.

A prospective study of community-acquired bloodstream infections among febrile adults admitted to Mulago Hospital in Kampala, Uganda.
Septicemia is a frequent cause of death in HIV-infected adults in developing countries. Additional prospective studies are needed to determine the etiology of bloodstream infections (BSI) in febrile HIV-infected adults and guide initial evaluation and treatment in this setting. We assessed the prevalence and etiology of community-acquired BSI among 299 consecutive febrile adult medical admissions to Mulago Hospital, Kampala, Uganda, over a 4-month period in 1997. ⋯ Bacteremia and disseminated tuberculosis are frequent causes of morbidity in febrile HIV-infected Ugandan adults. Initial empiric antibiotic coverage in this setting should be targeted toward the pneumococcus and gram-negative enteric bacilli, especially nontyphi Salmonella species. All patients presenting with chronic cough should be evaluated for tuberculosis.

Comparative Study
Cohort study on circumcision of newborn boys and subsequent risk of urinary-tract infection.
A decrease in risk of urinary-tract infection is one of the most commonly given reasons for circumcision of newborn boys. Previous studies have reported rates of UTI to be 10-20 times higher in uncircumcised than in circumcised boys. This population-based cohort study followed neonates in Ontario, Canada, prospectively to study the relation between circumcision and subsequent UTI risk. ⋯ Although our findings support the notion that circumcision may protect boys from UTI, the magnitude of this effect may be less than previously estimated.
