Viral hepatitis — a group of infectious diseases known as hepatitis A, B, C, D, and E — affects millions of people worldwide, causing both acute (short-term) and chronic (long-term) liver disease. The World Health Organization (WHO) data show an estimated 325 million people worldwide are living with chronic hepatitis B or chronic hepatitis C. Viral hepatitis causes more than one million deaths per year, a number comparable to deaths caused by tuberculosis and HIV combined. While deaths from tuberculosis and HIV have been declining, deaths from hepatitis are increasing.
World Hepatitis Day is July 28th and is an opportunity to learn about the global burden of this disease and CDC’s efforts to combat viral hepatitis around the world. People can also find out if they should be tested or vaccinated for hepatitis A, B or C by taking CDC’s online Hepatitis Risk Assessment(https://www.cdc.gov/hepatitis/riskassessment/index.htm), which is based on CDC recommendations for the United States.
What is CDC doing to help combat hepatitis globally?
The vision of CDC is to eliminate viral hepatitis in the United States and globally. When resources permit, CDC collaborates with WHO and other partners to help countries experiencing high rates of infection prevent and control viral hepatitis. Activities include improving viral hepatitis surveillance and planning and evaluating programs that can expand access to prevention interventions, clinical care, and treatments that can potentially prevent and cure millions of infections. CDC’s viral hepatitis laboratory also serves as a worldwide reference lab, providing recommendations to improve diagnostic quality for clinical laboratories around the world, which help ensure reliable, accurate, and quality diagnostics in viral hepatitis.
To prevent(https://www.cdc.gov/globalhealth/immunization/othervpds/preventing_hepatitisb.html) hepatitis B infection, CDC provides financial and technical assistance to WHO and countries’ immunization programs like those in the Solomon Islands, Philippines, Vietnam, Cambodia, Sierra Leone, Ethiopia, Uganda, Nigeria, Pacific Islands, Lao(https://www.cdc.gov/globalhealth/immunization/stories/laos-hep-b-vax.htm), Colombia, Haiti, and other countries by:
- Implementing innovative interventions to increase hepatitis B vaccine coverage at birth(https://www.cdc.gov/globalhealth/stories/eliminate-hepatitis.html#_ftnref7)
- Documenting the burden of hepatitis B in children
- Supporting countries in verifying the achievement of hepatitis B control and elimination goals
To decrease the burden of all viral hepatitis types, CDC assists WHO in developing guidelines for surveillance, testing, and treatment and helps China, Georgia(https://www.cdc.gov/globalhealth/healthprotection/gdd/stories/georgia_eliminate_hepatitis.html), Pakistan, Vietnam, and other countries develop national programs to prevent and control viral hepatitis.
CDC’s international work helps reduce the disease burden for travelers and people migrating to the United States, while identifying best practices that may serve as models for other countries, including the United States.
What are the different types of hepatitis viruses occurring around the world?
The five hepatitis viruses – A, B, C, D and E – are distinct; they can have different modes of transmission, affect different populations, and result in different health outcomes.
- Hepatitis A is primarily spread when someone ingests the virus from contact with food, drinks, or objects contaminated by feces from an infected person or has close personal contact with someone who is infected. Hepatitis A does not cause chronic liver disease and is rarely fatal, but it can cause serious symptoms. Hepatitis A can be prevented through improved sanitation, food safety, and vaccination.
- Hepatitis B is often spread during birth from an infected mother to her baby. Infection can also occur through contact with blood and other body fluids through injection drug use, unsterile medical equipment, and sexual contact. The hepatitis B virus is common in sub-Saharan Africa, Asia and the Pacific Islands, but also has increased rates in the Amazon region of South America, the southern parts of eastern and central Europe, the Middle East and the Indian subcontinent. The hepatitis B virus can cause both acute and chronic infection, ranging in severity from a mild illness lasting a few weeks to a serious, chronic illness. If infected at birth or during early childhood, people are more likely to develop a chronic infection, which can lead to liver cirrhosis or even liver cancer. Getting the hepatitis B vaccine is the most effective way to prevent hepatitis B. WHO recommends that all infants receive the hepatitis B vaccine as soon as possible after birth, followed by 2-3 additional doses. In many parts of the world, widespread infant vaccination programs have led to dramatic declines of new hepatitis B cases.
- Hepatitis C is spread through contact with blood of an infected person. Infection can occur through injection drug use and unsafe medical injections and other medical procedures. Mother-to-child transmission of hepatitis C is also possible. Hepatitis C can cause both acute and chronic infections, but most people who get infected develop a chronic infection. A significant number of those who are chronically infected will develop liver cirrhosis or liver cancer. With new treatments, over 90% of people with hepatitis C can be cured within 2-3 months, reducing the risk of death from liver cancer and cirrhosis. The first step for people living with hepatitis C to benefit from treatments is to get tested and linked to care. There is currently no vaccine for hepatitis C but research in this area is ongoing.
- Hepatitis D is passed through contact with infected blood. Hepatitis D only occurs in people who are already infected with the hepatitis B virus. People who are not already infected with hepatitis B can prevent hepatitis D by getting vaccinated against hepatitis B.
- Hepatitis E is spread mainly through contaminated drinking water. Hepatitis E usually clears in 4-6 weeks so there is no specific treatment. However, pregnant women infected with hepatitis E are at considerable risk of mortality from this infection. Hepatitis E is found worldwide, but the number of infections is highest in East and South Asia. Improved sanitation and food safety can help prevent new cases of hepatitis E. A vaccine to prevent hepatitis E has been developed and is licensed in China, but is not yet available elsewhere.
