From: Challenges to mapping the health risk of hepatitis A virus infection
Map Source | Title | Data Sources Listed | Target Audience | Risk Categories | Cutoffs for Risk Categories Listed | Notes |
|---|---|---|---|---|---|---|
CDC: Travelers' Health 2008 (Yellow Book) [24] | "Prevalence of antibody to hepatitis A virus, 2006" | No | Travel clinics and travelers from low prevalence areas | Prevalence of antibody to Hepatitis A Virus: * High * Intermediate * Low | No | "Estimates of prevalence of antibody to hepatitis A virus (anti-HAV), a marker of previous HAV infection, are based on limited data and might not reflect current prevalence. In addition, anti-HAV prevalence might vary within countries by subpopulation and locality. As used on this map, the terms 'high,' 'medium,' and 'low' endemicity reflect available evidence of how widespread HAV infection is within each country, rather than precise quantitative assessments." |
WHO: International Travel & Health Report (2008) [23] | "Hepatitis A, countries or areas at risk" | No | Travel clinics and travelers from low prevalence areas | * Countries or areas with moderate to high risk | No | "The risk of infection is based on estimated prevalence rate of antibody to hepatitis A (anti-HAV) - a marker of previous HAV infection - among population. This marker is based on limited data and may not reflect current prevalence." |
Jacobsen, 2010 [9] | "Estimated prevalence of hepatitis A virus, 2005" | Yes | Clinicians and researchers | Anti-HAV endemicity: * High * Intermediate * Low * Very low | Yes, by percent immune by age | "Evidentiary support indicated as very limited, limited, moderate, or extensive based on number of articles per country in each world region." |
Nothdurft, 2008 [26] | "Worldwide pattern of the prevalence of hepatitis A virus" | Yes | Clinicians and researchers | Anti-HAV prevalence: * High * Transitional * Intermediate * Low or Very Low | No | None listed. |
Bell, 2002 [25] | "Geographic distribution of the prevalence of hepatitis A virus" | No | Clinicians and researchers | Anti-HAV prevalence: * High * Transitional * Intermediate * Low or Very Low | No | "Based on summary of available data." |
