Viral hepatitis refers to inflammation of the liver caused by hepatitis viruses. The condition can range from a short-term infection to chronic liver disease that may lead to serious complications such as cirrhosis and liver cancer. The five major hepatitis viruses are hepatitis A, B, C, D, and E, and each differs in its transmission, health impact, and prevention methods.
According to the World Health Organization’s 2024 estimates, around 240 million people were living with chronic hepatitis B and approximately 47 million people were living with hepatitis C infection. Chronic hepatitis B and C together were associated with around 1.3 million deaths in 2024, mainly due to cirrhosis and liver cancer.
What Is Viral Hepatitis?
Viral hepatitis is inflammation of the liver caused by hepatitis viruses. The infection may be acute, meaning it lasts for a limited period, or chronic, as can occur particularly with hepatitis B and hepatitis C.
Not everyone develops noticeable symptoms, which means some infections can remain undiagnosed for years. Early testing and diagnosis are therefore important for reducing the risk of long-term liver complications.
What Are the Types of Viral Hepatitis?
There are five major types:
Hepatitis A: Usually spreads through contaminated food or water and does not normally become chronic.
Hepatitis B: Spreads through blood and certain body fluids and can become chronic.
Hepatitis C: Primarily spreads through exposure to infected blood and can become chronic, but modern treatment can cure the infection.
Hepatitis D: Occurs only in people who are also infected with hepatitis B.
Hepatitis E: Primarily spreads through contaminated water and is usually an acute infection.
Causes of Viral Hepatitis
Transmission varies according to the specific hepatitis virus. Hepatitis A and E are commonly spread through contaminated food or water, while hepatitis B and C are primarily transmitted through infected blood or, in certain circumstances, other body fluids.
Hepatitis B can also be transmitted from an infected mother to her baby during childbirth and through unsafe injections or contaminated sharp instruments.
Common Symptoms of Viral Hepatitis
Some people have no noticeable symptoms, particularly during the early stages. When symptoms occur, they may include fatigue, loss of appetite, nausea, vomiting, abdominal pain, fever, dark urine, pale stools, joint pain, and jaundice, which causes yellowing of the skin and eyes.
With chronic viral hepatitis, liver damage may progress gradually over many years before noticeable symptoms develop.
Treatment and Prevention of Viral Hepatitis
Treatment depends on the type of virus and the patient’s liver health. Hepatitis A usually requires supportive care, adequate hydration, and appropriate nutrition. Chronic hepatitis B may require antiviral medication and regular medical monitoring; these treatments are not considered a cure for the infection.
Hepatitis C, however, can now be cured in more than 95% of cases with direct-acting antiviral medications (DAAs), with many treatment courses lasting approximately 8–12 weeks.
Prevention includes hepatitis B vaccination, safe food and water practices, avoiding shared needles and contaminated sharp instruments, and appropriate testing for people with relevant risk factors.
Why Choose MCC for Viral Hepatitis Care?
At MCC Clinic, viral hepatitis care begins with appropriate medical assessment and diagnostic testing to identify the type of infection and evaluate its impact on liver health.
Our medical team develops an individualized care and follow-up plan based on each patient’s condition, monitors laboratory results and treatment response, and provides guidance on maintaining liver health and reducing the risk of complications.
Frequently Asked Questions
Is Viral Hepatitis Contagious?
Yes. Viral hepatitis can be contagious, but the route of transmission varies by type. Hepatitis A and E are primarily spread through contaminated food and water, while hepatitis B and C are mainly transmitted through infected blood or certain body fluids under specific circumstances. Prevention therefore depends on the type of hepatitis.
Which Is More Serious: Hepatitis C or Hepatitis B?
There is no single answer that applies to every patient. The potential severity depends on the type of infection, whether it becomes chronic, the condition of the liver, and the presence of complications.
Globally, WHO estimates for 2024 attribute approximately 1.1 million deaths to hepatitis B compared with around 240,000 deaths associated with hepatitis C.
However, hepatitis C has highly effective oral treatments that can cure more than 95% of infections, while chronic hepatitis B can be effectively managed with antiviral treatment and monitoring in eligible patients, although treatment is generally not considered curative.
