Viral Hepatitis (A, B, C, E)

What is Viral Hepatitis (A, B, C, E)?

Viral hepatitis is inflammation of the liver caused by a virus. The main types are hepatitis A, B, C, and E. Each virus spreads differently and affects your liver in unique ways. Some infections go away on their own while others become chronic and cause long-term damage.

Your liver filters toxins, makes proteins, and stores energy. When a hepatitis virus infects liver cells, it triggers inflammation and damages tissue. This injury disrupts normal liver functions. Hepatitis A and E usually cause short-term infections. Hepatitis B and C can become chronic, meaning the virus stays in your body for years.

Early detection through blood testing helps protect your liver before serious damage occurs. Many people have no symptoms until liver function declines significantly. Regular screening can catch infections when they are easier to treat and manage.

Symptoms

Fatigue and weakness lasting weeks or months
Loss of appetite and nausea
Abdominal pain, especially in the upper right side
Dark urine or pale stools
Yellowing of skin and eyes, called jaundice
Joint pain and muscle aches
Low-grade fever
Itchy skin

Many people with hepatitis B and C have no symptoms for years. The virus can silently damage the liver before any warning signs appear. This is why blood testing matters even when you feel fine.

Causes and risk factors

Each hepatitis virus spreads through different routes. Hepatitis A and E spread through contaminated food and water, often in areas with poor sanitation. Hepatitis B spreads through contact with infected blood, unprotected sex, and from mother to baby during birth. Hepatitis C spreads primarily through blood contact, such as sharing needles or receiving contaminated blood products before 1992.

Risk factors include traveling to areas where hepatitis is common, getting tattoos or piercings with unsterile equipment, sharing needles, having multiple sexual partners, and working in healthcare settings. People born between 1945 and 1965 have higher rates of hepatitis C. Babies born to infected mothers are at risk for hepatitis B. Alcohol use and other liver conditions worsen hepatitis damage.

How it's diagnosed

Doctors diagnose viral hepatitis through blood tests that detect viral proteins, antibodies, and signs of liver injury. Specific tests identify which virus type you have and whether the infection is acute or chronic. Blood panels also measure liver enzymes and function markers to assess damage levels.

Rite Aid offers blood testing at Quest Diagnostics locations nationwide to screen for liver function changes. Our panel includes urine urobilinogen, which becomes elevated when liver cells are injured and cannot properly process bile pigments. Testing helps catch hepatitis early, even before symptoms start. Regular monitoring guides treatment decisions and tracks liver health over time.

Treatment options

Rest and adequate sleep to help your body heal
Avoid alcohol completely to prevent further liver damage
Eat small, frequent meals if nausea is present
Drink plenty of water to stay hydrated
Avoid medications that stress the liver, including acetaminophen
Antiviral medications for chronic hepatitis B and C
Interferon therapy in some cases
Vaccination to prevent hepatitis A and B
Liver transplant for severe cirrhosis or liver failure

Hepatitis A and E usually resolve without medication in 2 to 6 months. Chronic hepatitis B and C require antiviral drugs that suppress the virus and prevent liver scarring. Modern hepatitis C treatments cure over 95% of infections in 8 to 12 weeks. Work with a doctor who specializes in liver disease to monitor your condition and adjust treatment as needed.

Frequently asked questions

Each type is caused by a different virus and spreads in unique ways. Hepatitis A and E spread through contaminated food and water and usually resolve on their own. Hepatitis B and C spread through blood and sexual contact. Both B and C can become chronic infections that last for years and cause serious liver damage if untreated.

Hepatitis A and E almost always clear up without treatment in 2 to 6 months. About 90% of adults with acute hepatitis B also clear the virus naturally. However, chronic hepatitis B and C persist in the body and require antiviral medication. Early treatment prevents long-term complications like cirrhosis and liver cancer.

Hepatitis A and E spread through eating or drinking contaminated food and water. Hepatitis B spreads through blood, semen, and other body fluids during sex, needle sharing, or from mother to baby at birth. Hepatitis C spreads mainly through blood contact, such as sharing needles or receiving transfusions before 1992. Casual contact like hugging does not spread any hepatitis virus.

Everyone born between 1945 and 1965 should get tested once for hepatitis C. People who inject drugs, receive dialysis, have HIV, or had blood transfusions before 1992 need testing. Healthcare workers exposed to blood should be screened. Anyone with symptoms of liver disease or elevated liver enzymes needs hepatitis testing to identify the cause.

Specific antibody and antigen tests identify each hepatitis virus type. Liver enzyme tests measure damage to liver cells. Urobilinogen in urine becomes elevated when hepatitis damages the liver and disrupts bile processing. Viral load tests measure how much virus is in your blood. These tests together confirm diagnosis and guide treatment decisions.

Vaccines exist for hepatitis A and B but not for hepatitis C or E. The hepatitis A vaccine is given in 2 doses, 6 months apart. The hepatitis B vaccine requires 3 doses over 6 months. Both vaccines are safe and highly effective. Many people receive a combination vaccine that protects against both A and B at once.

Chronic hepatitis C can be cured in over 95% of cases with modern antiviral pills taken for 8 to 12 weeks. Chronic hepatitis B cannot usually be cured but can be controlled with antiviral medications that suppress the virus. Treatment prevents cirrhosis, liver failure, and liver cancer. Regular monitoring helps track liver health and adjust treatment when needed.

Untreated chronic hepatitis B and C cause progressive liver scarring called cirrhosis over 10 to 30 years. Cirrhosis leads to liver failure, internal bleeding, fluid buildup, and confusion. Chronic hepatitis also raises the risk of liver cancer. Early treatment stops disease progression and prevents these serious complications.

Avoid alcohol completely, as it accelerates liver damage. Maintain a healthy weight to prevent fatty liver disease. Check with your doctor before taking any medications or supplements that might harm the liver. Get vaccinated for hepatitis A and B if you have hepatitis C. Eat a balanced diet with plenty of vegetables and lean protein.

People with chronic hepatitis need blood tests every 3 to 6 months to monitor liver function and viral load. More frequent testing may be needed when starting new medications or if liver enzymes become elevated. Regular screening for liver cancer is recommended every 6 months if you have cirrhosis. Your doctor will create a monitoring schedule based on your specific condition and treatment response.
