Groups/Cohorts Assigned Interventions
Possible hepatitis A Cohort
Children with an acute disease characterized by discrete onset of symptoms and jaundice
Procedure: Serum sample
Serum samples collected
Probable hepatitis A Cohort
Children with an increase in serum levels of transaminase 2.5 times higher than the maximum limit of the normal interval
Procedure: Serum sample
Serum samples collected
Confirmed hepatitis A Cohort
Children presenting a positive result for Immunoglobulin M for hepatitis A virus
Procedure: Serum sample
Serum samples collected

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.
