What is Hepatitis (A, B, C)?

Hepatitis refers to the swelling of the liver. It can be caused by viral infections, chemicals, drug abuse, some medications and immune disorders. There are several forms of viral hepatitis including hepatitis A, B and C, which are caused by hepatitis A, B, and C viruses, respectively.

Each type of viral hepatitis is spread by different methods and needs different treatment.

Hepatitis A virus infection causes acute inflammation (swelling) of the liver and is a self-limiting disease with symptoms lasting for several weeks before the individual can recover completely. It leads to lifelong immunity.

Hepatitis B infection is the most common infection of the liver. The majority of infected individuals recover from acute hepatitis B infections and become immune to them. However, some people can develop a long-term hepatitis B infection, which leads to serious complications including chronic hepatitis, liver cirrhosis (scarring of the liver), liver failure and liver cancer.

Hepatitis C infection is responsible for the development of chronic liver disease worldwide. Most infected people can’t get rid of the virus, and thus the virus causes ongoing damage to the liver over the years. Both hepatitis B and hepatitis C are the leading cause of chronic hepatitis, cirrhosis, liver failure and liver cancer worldwide.

Hepatitis (a, B, C)

What are the causes of Hepatitis A, B, and C?

Hepatitis A virus is transmitted through:

  • Blood contact, drug use and sexual contact with infected persons
  • Consuming shellfish from water contaminated with sewage
  • Direct contact with food, drinks or objects contaminated with the faeces of an infected individual
  • The “faecal-oral” route in areas of poor hygiene and overcrowding

Hepatitis B virus is mainly found in the blood, and it can also be found in semen and vaginal secretions. Hepatitis B can be acquired through:

  • Infected expecting mothers can transmit the infection to their newborns during childbirth.
  • Other activities involve contaminated blood entering the bloodstream of a susceptible individual.
  • Sharing contaminated injections among drug use.
  • Unsafe sexual contact with an infected person.

Hepatitis C virus is mainly found in the blood and is transmitted when the blood of an infected person enters the bloodstream of a susceptible person, like drug users sharing contaminated needles.

What are the symptoms of Hepatitis A, B, and C?

Some hepatitis patients are asymptomatic. However, the general symptoms may include any of the following:

  • Abdominal pain or discomfort
  • Dark urine
  • Decreased appetite
  • Fever
  • Jaundice (yellowish skin and eyes)
  • Tiredness
  • Nausea and dizziness
  • Oedema (swelling due to fluid build-up)
  • Painful joints
  • Pale stools

How is hepatitis A, B, and C treated?

Hepatitis A

There is no specific treatment for hepatitis A but there are treatment measures that help improve your condition:

  • Avoid drinking alcohol.
  • Getting plenty of bed rest.
  • Increasing fluid intake.
  • Practising good personal hygiene to prevent faecal-oral transmission to other individuals.
  • Taking prescribed medication if your symptoms worsen.

Hepatitis B

Treatment of hepatitis B depends on the symptoms and stage of your disease and includes:

  • Antiviral medication to stop the virus from replicating.
  • Medication to ease symptoms.

Hepatitis C

Treatment of hepatitis C aims to delay its complications, and these include:

  • Antiviral medication to stop the virus from replicating.
  • Avoid drinking alcohol as it can increase liver damage.
  • Regular screening for liver cancer for hepatitis C carriers, especially those who have liver cirrhosis (scarring of the liver).
