Current challengesCurrent challenges

HBV– HepB vaccine at birth is still only administered in 92 Member

States and only 25% of infants have received this vaccine.

HBV / HCV– Millions of chronically infected persons do not have timely access

to testing, care and effective treatments.– Unsafe injections are still common in many developing countries. – On-going transmission is adding millions of people to the pool of

the chronically infected.

HAV / HEV– Unsafe water and sanitation are the norm for millions of people.

Vision and GoalsVision and Goals

As of Dec 2011, WHO Global Hepatitis Programme

«A world where viral hepatitis transmission is stopped and all have access to safe and effective care and treatment»

Using a public health approach, the goal of the viral hepatitis programme is:

– to reduce the transmission of the various agents that cause viral hepatitis;

– to reduce the morbidity and mortality due to viral hepatitis and improve the care of patients with viral hepatitis;

– and to reduce the socio-economic impact of viral hepatitis at individual, community and population levels.

Current estimates of Disease BurdenCurrent estimates of Disease Burden

HBV

1 of every 3 people has been infected by HBV

~240 million chronic carriers worldwide (3,7%)

~ 500 000 – 700 000 HBV related deaths per year, 94% chronic reasons

~4,5 million new cases/per year

HCV

130-170 millions of peopled

infected worldwide (2.2-3%)

>350 000 people die from HCV-related liver diseases each year

3–4 million people are infected with HCV each year

WHO Public Health Research Agenda for Viral Hepatitis

WHO Public Health Research Agenda for Viral Hepatitis

The goal is to guide researchers in the direction of necessary research for generation of evidence needed to strengthen public health guidance and actions.

Examples of public health research questions:

What strategies are most useful in reaching high risk groups for Hepatitis B vaccination and increasing uptake?

What is the most cost-effective HCV screening strategy in settings with limited treatment resources?

Is it more cost-effective to focus on building infrastructure or to immunize children with the hepatitis A vaccine to reduce morbidity and mortality in low to middle income countries?

Axis 3: Prevention of virus transmission

Guidance and tools for immunization – Schedules and dosages – Protection of high risk groups including newborns and health-

care workers, especially against hepatitis B– Promote innovative approaches for the future

Safer sex, safe and rational use of injections and safe blood transfusion

– ensuring safe food and water for countries, and on proper disposal of sanitary waste
