Acute Hepatitis A, Hepatitis
Conditions
Brief summary
The purpose of this study is to collect epidemiological and clinical data to assess the vaccine impact and occurrence of confirmed acute hepatitis A cases in sentinel hospitals after the introduction of Havrix™ into the Expanded Program of Immunization.
Detailed description
This is an observational, prospective, multi-centre, sentinel based study in 3 hospitals in Panama. Hospitals are selected based on population density or hepatitis A disease burden. The Pan American Health Organization (PAHO) definition for a possible case of acute hepatitis A are used for subjects aged between \>1 month and \<15 years. Data regarding clinical and epidemiologic information are collected and serum samples are collected to test hepatitis A markers and determine if infection with hepatitis A virus has recently occurred. Surveillance will be for a period of approximately 2.5 years from the date of study initiation.
