Abstract
Acute hemorrhagic conjunctivitis (AHC) is an epidemic form of highly contagious conjunctivitis and is characterized by sudden onset of painful, swollen, red eyes, with conjunctival hemorrhaging and excessive tearing. Since 1981, when AHC was first detected in the Western Hemisphere, three major epidemics had occurred until 2003, all affecting the Caribbean. During August-October 2003, a fourth epidemic occurred in Puerto Rico (2000 population: 3.8 million). This report summarizes the outbreak investigation conducted by the Puerto Rico Department of Health (PRDOH), which documented an estimated 490,000 persons with illness, including >51,000 cases reported by physicians; demonstrated laboratory evidence of Coxsackievirus A24 (CA24); and determined that school-aged children (i.e., aged 5-18 years) and those living in crowded urban areas were at highest risk. To control outbreaks of AHC, prevention methods (e.g., frequent hand washing and avoidance of sharing towels and bedding) should be targeted to groups at highest risk, and information should be disseminated after the first report of AHC in the area.
