WASHINGTON — Stepped-up vaccination requirements, a boost in resources for prevention and treatment, and a public awareness campaign similar to the effort that dispelled the stigma of HIV/AIDS are needed to curb the health threats posed by hepatitis B and hepatitis C, according to a report from the Institute of Medicine that was released Jan. 11.
Chronic hepatitis B and C cause thousands of cases of liver cancer, liver disease and death each year — taking the heaviest toll among Asians, Pacific Islanders and blacks in the U.S. — and these infections account for nearly half of the liver transplantations that must be performed annually.
In the next 10 years, these two liver-damaging infections will kill about 150,000 people in the U.S. alone, the new report states.
Resources and efforts to contain the viruses that cause hepatitis B and C lag behind those directed at other infectious diseases of similar impact to public health, noted the committee that wrote the report.
"Although hepatitis B and C are preventable, the rates of infection have not declined over the past several years, underscoring the conclusion that we have allowed gaps in screening, prevention and treatment to go unchecked," said committee chairman R. Palmer Beasley, professor of epidemiology and disease control at the University of Texas School of Public Health in Houston.
"This report outlines the additional resources and actions needed to reduce the unacceptably high burden of liver disease and cancer associated with these viruses."
An estimated 800,000 to 1.4 million Americans have chronic hepatitis B and between 2.7 million and 3.9 million have chronic hepatitis C. Most infected individuals are not aware of their condition until they develop symptoms of liver cancer or liver disease.
Few among the populations most at risk — immigrants from countries where the diseases are endemic, non-Hispanic black men, injection-drug users and people who had blood transfusions before 1992 — seek testing or information on how to protect themselves from infection. Moreover, health care and social service providers' knowledge about hepatitis B and C is generally poor, and many fail to follow guidelines for screening patients and providing prevention, treatment, and follow-up services.
The report calls for a public awareness initiative along the lines of the effort that succeeded in increasing recognition, prevention, and treatment of HIV/AIDS, which affects three to five times fewer Americans than viral hepatitis. Educational programs and materials that outline risk factors for viral hepatitis and provide information on immunization, prevention and proper monitoring of infected individuals should be developed and made available to all health professionals and social service providers.
Although the availability of an effective vaccine against hepatitis B has significantly reduced its spread, some 1,000 infants born to infected mothers develop chronic infections each year, a number that has not declined over the past decade.
Moreover the report stated, three states — Alabama, Montana, and South Dakota — still do not require that children be vaccinated against hepatitis B before entering day care or school. All full-term newborns whose mothers test positive for hepatitis B should receive the vaccine once they are stable and before leaving the delivery room rather than up to 12 hours after birth as is currently recommended.
All states should make hepatitis B vaccination a requirement for school attendance, and health plans need to fully cover the costs associated with the immunization, the report advocates. Particular attention should be given to screening and vaccinating children who were born in countries where hepatitis B circulates widely. Each year, roughly 40,000 to 45,000 people legally immigrate to the United States from countries where hepatitis B is endemic.
Health care and social services related to viral hepatitis are sparse and fragmented among providers and organizations, leading to missed opportunities to prevent the spread of infection and to lessen the impact of chronic infections, the report concludes.
