Hepatitis B



 Hepatitis refers to the inflammation of the liver parenchyma. The liver can be inflamed as a result of infection,disorder of immune system,exposure to certain medications and poison etc.HEPATITIS B is a viral infection that attacks the liver and can cause both acute and chronic diseases.
          Having a chronic Hepatitis B virus may eventually lead to serious liver diseases such as cirrhosis and liver cancer.Also,having had the infection as an infant or child increases the risk of developing these illnesses as an adult and it puts you at a risk of acute liver failure.

       RISK FACTORS OF HEPATITIS B VIRUS(HBV)
-Every person is at risk for infection.
-All infants at birth especially from infected mothers.
-Health care professionals and emergency personnel.
-Persons with high risk sexual behavior.
-Patients with kidney disease and undergoing dialysis.

MODE OF TRANSMISSION
-It varies with age,transmission occurs at 3 important times of life which are during;
birth,in early childhood and adult life.

-The virus is carried in blood and in other body fluids including saliva,tears,semen and vaginal secretions and can be transmitted from person to person through variety of means.

-The modes of transmission in developing countries are

Perinatal(from mother to baby at birth)

Early childhood infections.

Unsafe injection practices.

Blood transfusion.

Sexual contact.


TREATMENT
1. The use of drugs such as;Anti-viral(Iamivudine,adefovir,tenofovir etc).

2. Acute HB infection does not usually require treatment because most adults clear the infection spontaneously.Early antiviral treatment may only be required in fewer than 1% of patients whose infection  takes a very aggressive course or who are immunocompromised.

3. On the other hand treatment of chronic infection may be necessary to reduce the risk of cirrhosis and liver cancer .Although non of the drugs available can clear the infection,they can stop virus from replicating and minimize liver damage.
