The American Liver Foundation Urges Cautious Optimism About CDC Report On Declining Acute Hepatitis Infection Rates
The Centers for Disease Control and
Prevention (CDC) has reported that significant decline in the rates of new
acute hepatitis infections in the United States in the last 10 years,
reflecting the success of hepatitis A and B vaccination programs. The
American Liver Foundation wants to highlight these positive results, but
remind people that chronic hepatitis B and C are very serious diseases that
affect over five million Americans and that the prevalence of chronic
hepatitis C infection is actually increasing. This is in response to the
article "Surveillance for Acute Viral Hepatitis -- United States, 2005,"
published by the CDC in their publication Morbidity and Mortality Weekly
Report.
Acute, or short-term, infections are more common with hepatitis A and B
and less likely to cause serious health problems than a chronic, or
long-term, infection. Hepatitis A does not cause chronic infections. Only
five percent of all adults infected with hepatitis B develop chronic
infection, although 90 percent of infants infected with hepatitis B do
develop chronic hepatitis B. On the other hand, hepatitis C becomes a
chronic infection for 70-80% percent of those exposed to the virus.
"I was very pleased to read this report about the decline in acute
hepatitis infections," said Dr. James Boyer, Chair of the Board of the
American Liver Foundation and Director of the Liver Center at the Yale
University Medical School. "But this good news must not let us forget the
millions of Americans suffering with chronic hepatitis. Without diagnosis
and treatment these people are in serious risk of developing cirrhosis and
liver cancer. Much more work needs to be done to combat hepatitis in this
country."
With nearly two percent of Americans infected with the hepatitis C
virus, the costs of this disease to the health care system is severe. A
study conducted in 2002 estimated total medical expenditures for people
with hepatitis C at $15 billion per year. The projected direct and indirect
costs of hepatitis C, if infection rates do not continue to drop
significantly, will be $85 billion for the years 2010-2019 as the number of
people chronically infected will continue to increase.
Facts about hepatitis
-- There are five distinct types of hepatitis: A, B, C, D, and E. All
cause inflammation of the liver
-- The hepatitis B virus is 100 times more infectious than HIV
-- It is estimated that there are 1.4 million Americans with chronic
hepatitis B
-- Hepatitis B and C can lead to liver cancer
-- There are vaccines for hepatitis A and B. There is no vaccine for
hepatitis C
-- Hepatitis C is the most common blood-borne infection in the United
States
-- Almost 4 million Americans, or 1.8 percent of the U.S. population, are
or have been infected with hepatitis C
-- Recent studies suggest that approximately 40 percent of the 2.2 million
people in America's prison system are infected with hepatitis C
