Investigation of recent outbreaks of ETEC gastroenteritis on 3 cruise ships indicated that all were associated with consuming beverages with ice cubes on board the ship (relative risk [RR], 1.4, 95% confidence interval [CI], 1.0–1.9, P = .02; RR, 1.9, 95...

Enteropathogens and Other Factors Associated with Severe Disease in Children with Acute Watery Diarrhea in Lima, Peru

Case-Control Study of Risk Factors for Human Infection with a New Zoonotic Paramyxovirus, Nipah Virus, during a 1998–1999 Outbreak of Severe Encephalitis in Malaysia
