RESUMEN
In 1998, we investigated a suspected outbreak of amebic liver abscesses caused by Entamoeba histolytica in the Republic of Georgia, using a case-control study. A questionnaire was administered and blood samples were obtained from cases and controls for serologic diagnosis. Medical records showed that E. histolytica infections were rarely diagnosed before 1998. However, from July through September 1998, 177 cases of suspected amebiasis were identified. Of 52 persons who had diagnosed liver abscesses, 37 (71%) were confirmed serologically to have antibodies against E. histolytica, compared with 11 of 53 persons (20.8%) diagnosed with intestinal amebiasis. In addition, 9-14% of asymptomatic controls were seropositive. Logistic regression identified the fact that interruptions in the water supply, decreases in water pressure, and increased water consumption were significantly associated with infection. The data support the hypothesis that drinking water was the source of infection, either because of inadequate municipal water treatment or contamination of municipal water in the distribution system.

In Taiwan, a temperature-monitoring campaign and hotline for severe acute respiratory syndrome (SARS) fever were implemented in June 2003. Among 1,966 calls, fever was recorded in 19% (n = 378); 18 persons at high risk for SARS were identified. In a cross-sectional telephone survey, 95% (n = 1,060) of households knew about the campaign and 7 households reported fever.

This report updates CDC's recommendations for using yellow fever vaccine (CDC. Yellow Fever Vaccine: Recommendations of the Advisory Committee on Immunizations Practices: MMWR 1990;39[No. RR-6]1-6). The 2002 recommendations include new or updated information regarding 1) reports of yellow fever vaccine-associated viscerotropic disease (previously reported as febrile multiple organ system failure); 2) use ofyellow fever vaccine for pregnant women and persons infected with human immunodeficiency virus (HIV); and 3) concurrent use of yellow fever vaccine with other vaccines.
