From VOA Learning English this is the Health & Lifestyle Report.
The first-ever World Hepatitis Summit was held in
September of this year in Glasgow, Scotland. Health experts estimate that about
400 million people are infected with the viral disease.
Viral hepatitis infections kill nearly 1 million people a
year. The majority of cases are in Asia and in African countries south of the
Sahara.
A vaccine and treatment for some forms of hepatitis are
now available. But whether patients have enough money to pay for treatments is
a different story.
The World Health Organization says high cost of drugs is
one big problem in fighting hepatitis. Another problem is the fact that most
people living with hepatitis do not know they are infected.
Hepatitis explained
There are five different hepatitis viruses: A, B, C, D
and E. All five cause inflammation of the liver. The organ can become enlarged
and painful.
Hepatitis A, E and D
Hepatitis A and E are spread through infectious waste in
food or water. These forms of the disease cause acute infection. However, most
people recover. The best way to prevent Hepatitis A is by getting a
vaccination. But the U.S. Federal Drug Agency has yet to approve a vaccine for
Hepatitis E.
Hepatitis E is usually found in countries with polluted
water supplies and poor waste treatment systems. Hepatitis D only infects
people already infected with the B virus.
Hepatitis B and C are a different story
Hepatitis B and C can be the most serious. Those two
types are responsible for 80 percent of all liver cancer deaths.
Dr. Stefan Wiktor is the Team Lead of the World Health
Organization's Global Hepatitis Program. He says hepatitis B and C are also
different from the other types in how they are spread.
“Hepatitis B and C are transmitted by blood. So
that means from a mother to a child; through blood transfusions or
through injections. Hepatitis B can also be transmitted by sex. So,
there are different routes of transmission.”
You can get hepatitis B from sexual contact or by sharing
drug-injection equipment. The best way to prevent Hepatitis B is by getting
vaccinated. Hepatitis B is common worldwide, especially in many parts of Asia
and the Pacific Islands.
With hepatitis C, most people become infected by sharing
instruments like needles. The majority of infected persons with hepatitis C
might not know they are infected because they do not feel sick. There is no
vaccine for hepatitis C. The best way to prevent hepatitis C is by avoiding
behaviors that can spread the disease.
Available treatments
Dr. Wiktor says there are ways to prevent all types of
hepatitis.
“Luckily, we have ways to prevent all of them. There's a
great vaccine for Hepatitis B that is effective for life. And there are
treatments for both B and C. So, there are now in hand means of preventing and
treating both infections. So, really, this is a time to act and that’s really
the point of this summit.”
Not so long ago, treating Hepatitis C was difficult with
a very low recovery rate. Now, people are able to be cured completely of the
virus. Dr. Wiktor considers this a major development.
“One of the most remarkable advances in the
development of medicines is the development of treatments for hepatitis C.
Until recently, it was very difficult to cure. It required weekly injections
and only half the people who started the medicines were cured. Now, the
medicines are about 12 weeks of treatment. One pill a day and almost everyone
is cured. And cured means the virus is gone from their body.”
Although a vaccine and treatments are available, says Dr.
Wiktor, not everyone in need can get them. He says this is a big problem. The
Global Hepatitis Program says that about 240 million people are infected with
chronic hepatitis B. And anywhere between 130 and 150 million people worldwide
are infected with hepatitis C.
“The problem has been that these medicines are very
expensive. In the U.S., for example, they cost more than $100,000 to treat one
person just for the medicines. Luckily, the lower income countries have been
able to get these same medicines at (a) much lower price. But a lot more has to
happen to make these drugs affordable.”
One of the goals of the recent summit was to urge
countries to develop national hepatitis treatment and prevention programs.
The WHO says people need to be aware how the disease
spreads and how to treat it. If left untreated, hepatitis kills slowly. It can
take 10 or more years for the virus to destroy the liver.
