Hepatitis
is an infectious disease caused by the hepatitis virus types A, B, and C, which
causes liver-related diseases such as Hepatitis A, B, C, liver cirrhosis,
hepatocellular carcinoma, and liver failure. It is possible that the infected
person will die as a result. The infection is spread through the transmission
of the hepatitis A and hepatitis B viruses through contact with infected
people's body fluids (blood, for example). Hepatitis
vaccines are available for the prevention of both hepatitis A and
hepatitis B, and they work by increasing the person's immunity, preventing
complications such as liver failure and cancer. Children are the most
vulnerable to infection. Hepatitis B is more common in the world than hepatitis
A.
When is the hepatitis vaccine
administered?
The
HEPA vaccine is recommended for children aged 12 months and up, with a
follow-up dose at least 6 months later. If a baby is going to a place where
hepatitis A is common, HEPA can be given as early as 6 months of age. After the
first birthday, the baby will still require routine vaccinations.
Where is Hepatitis most prevalent?
Foreign-born
individuals, particularly those born in Asia, the Pacific Islands, and Africa,
have the highest rates of chronic hepatitis B infection in the United States.
Approximately 70% of cases in the United States are among people born outside
of the country.
Hepatitis is a liver inflammation caused by a
viral infection. Hepatitis is a major cause of healthcare burden in both
developed and developing countries. Patients with autoimmune disorders are
contributing to the rise in hepatitis prevalence. This steady growth is being
aided by an aging population and varying societal behavior. Rising viral
infections such as type A, B, C, D, E, and possibly G are the leading causes of
hepatitis. Chronic hepatitis can be caused by hepatitis B and C. Acute
hepatitis A symptoms include fatigue, flu-like symptoms, and dark urine,
whereas chronic hepatitis symptoms are mild and non-specific.
Hepatitis is one of the most common
infectious diseases worldwide, and its severity has drawn the attention of
health organizations such as the World Health Organization (WHO). The rising
global incidence of hepatitis is expected to drive growth in the hepatitis
vaccine.
