BACKGROUND High rates of typhoid fever in children in urban settings in Asia have led to focus on childhood immunization in Asian cities, but not in Africa, where data, mostly from rural areas, have shown low disease incidence. We set out to compare incidence of typhoid fever in a densely populated urban slum and a rural community in Kenya, hypothesizing(More)
An outbreak of Chikungunya virus (CHIKV) disease associated with high fever and severe protracted arthralgias was detected in Lamu, Kenya, peaking in July 2004. At least 1,300 cases were documented. We conducted a seroprevalence study to define the magnitude of transmission on Lamu Island. We conducted a systematic cross-sectional survey. We administered(More)
BACKGROUND Characterizing infectious disease burden in Africa is important for prioritizing and targeting limited resources for curative and preventive services and monitoring the impact of interventions. METHODS From June 1, 2006 to May 31, 2008, we estimated rates of acute lower respiratory tract illness (ALRI), diarrhea and acute febrile illness (AFI)(More)
Malnutrition in sub-Saharan Africa contributes to high rates of childhood morbidity and mortality. However, little information on the nutritional status of children is available from informal settlements. During the period of post-election violence in Kenya during December 2007-March 2008, food shortages were widespread within informal settlements in(More)
More than 63,000 Iraqi refugees were resettled in the United States from 1994 to 2010. We analyzed data for all US-bound Iraqi refugees screened in International Organization for Migration clinics in Jordan during June 2007–September 2009 (n = 18,990), to describe their health profile before arrival in the United States. Of 14,077 US-bound Iraqi refugees(More)
We conducted a survey among Iraqi refugees resettled in the United States to assess their physical and mental health status and healthcare access and utilization following the initial 8-month, post-arrival period. We randomly selected Iraqi refugees: ≥18 years of age; living in the United States for 8–36 months; and residents of Michigan, California, Texas(More)
BACKGROUND In sub-Saharan Africa, most people with HIV do not know they are infected. METHODS We conducted door-to-door home-based testing and counseling (HBTC) in rural western Kenya (Lwak) and an informal urban settlement in Nairobi (Kibera) in 2008. After consent, eligible persons (adults and adolescents aged 13 years or older and children aged 12(More)
BACKGROUND In African settings with poor access to health care, surveillance and surveys of disease burden are often done through home visits. The optimal recall period to capture data on symptoms and health utilization is unknown. METHODS We collected illness data among 53 000 people during fortnightly home visits in rural and urban Kenya. Dates of(More)
BACKGROUND Refugees are at risk for poor outcomes from acute respiratory infections (ARI) because of overcrowding, suboptimal living conditions, and malnutrition. We implemented surveillance for respiratory viruses in Dadaab and Kakuma refugee camps in Kenya to characterize their role in the epidemiology of ARI among refugees. METHODS From 1 September(More)
An outbreak of watery diarrhea struck within the Kakuma refugee camp in Kenya in April 2005; 418 people were treated, and 4 persons died. Vibrio cholerae O1 was isolated from 33 patients. In June 2005, we conducted a retrospective matched case-control study to define risk factors associated with cholera among camp residents and identify interventions that(More)
