Primary Outcome Measures:
  • Occurrence of confirmed acute hepatitis A cases identified in the selected sentinel hospitals during the study period by age group, area of residence and year of surveillance [ Time Frame: average time-frame: 2.5 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

  • Risk factors for confirmed cases of acute hepatitis A [ Time Frame: average time-frame: 2.5 years ] [ Designated as safety issue: No ]
  • Frequency of different clinical signs and symptoms of hepatitis A [ Time Frame: average time-frame: 2.5 years ] [ Designated as safety issue: No ]

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.


Ages Eligible for Study:   1 Month to 15 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Children aged >1 month and <15 years of age being seen for possible acute hepatitis A during the study time period at the selected sentinel hospitals of Panama

Inclusion Criteria:

  • A male or female between >1 month and <15 years of age at the time of enrolment, being referred to any of the 3 participating sentinel hospitals.
  • Subjects with clinical diagnosis of possible acute hepatitis A.
  • Written informed consent obtained from the parent or guardian of the subject.
  • Subjects for whom a blood sample is collected.

Exclusion Criteria:

  • Subjects with confirmed diagnosis of non-viral hepatitis
