Acute Viral Hepatitis (Hepatitis A, B, C, D, E)
What is Acute Viral Hepatitis (Hepatitis A, B, C, D, E)?
Acute viral hepatitis is inflammation of the liver caused by one of five specific viruses. These viruses are labeled A, B, C, D, and E. Each type spreads differently and affects the liver in distinct ways. When a hepatitis virus enters your body, it attacks liver cells and causes them to become inflamed and damaged.
The liver is a vital organ that filters toxins, produces proteins, and stores energy. When hepatitis viruses damage liver cells, the organ cannot perform these jobs as well. Most people with acute viral hepatitis recover fully within weeks to months. However, some types like hepatitis B and C can become chronic, meaning the infection lasts longer than six months.
Early detection through blood testing helps identify liver damage before serious complications develop. Catching viral hepatitis early allows for better management and prevents the spread to others. Understanding which type of hepatitis you have guides the right treatment approach.
Symptoms
- Fatigue and weakness that interferes with daily activities
- Yellowing of the skin and eyes, called jaundice
- Dark urine that looks like cola or tea
- Pale or clay-colored stools
- Abdominal pain or discomfort in the upper right side
- Loss of appetite and nausea
- Vomiting and digestive upset
- Low-grade fever
- Joint pain and muscle aches
- Itchy skin without a rash
Many people with acute viral hepatitis have mild symptoms or no symptoms at all in the early stages. This is especially common in children and young adults. Some people only discover they have hepatitis after a routine blood test shows elevated liver enzymes.

Causes and risk factors
Each type of viral hepatitis spreads through different routes. Hepatitis A and E spread through contaminated food or water, often in areas with poor sanitation. Hepatitis B, C, and D spread through contact with infected blood or body fluids. This can happen through sharing needles, unprotected sex, or from mother to baby during childbirth. Healthcare workers may be exposed through needlestick injuries.
Risk factors include traveling to countries where hepatitis is common, sharing personal items like razors or toothbrushes, getting tattoos or piercings with unsterilized equipment, and receiving blood transfusions before 1992. People who inject drugs, have multiple sexual partners, or live with someone who has hepatitis face higher risk. Hepatitis D only occurs in people already infected with hepatitis B. Strengthening your immune system through good nutrition and lifestyle habits may help your body fight off viral infections more effectively.
How it's diagnosed
Doctors diagnose acute viral hepatitis through blood tests that measure liver enzymes and detect specific viral proteins or antibodies. Alanine Aminotransferase, known as ALT, is a key marker that rises dramatically during acute viral hepatitis. ALT levels can spike 10 to 100 times higher than normal when the virus damages liver cells. This elevation often appears before jaundice develops and helps doctors confirm liver inflammation.
Additional blood tests identify which specific hepatitis virus is causing the infection. These tests look for viral antigens, antibodies your immune system produces, or genetic material from the virus itself. Rite Aid offers blood testing that includes ALT monitoring to detect liver damage early. Getting tested helps you understand your liver health and catch problems before symptoms appear. If ALT levels are elevated, your doctor can order more specific tests to determine the exact cause.
Treatment options
- Rest and reduce physical activity to let your liver heal
- Stay hydrated by drinking plenty of water throughout the day
- Eat small, frequent meals that are easy to digest
- Avoid alcohol completely, as it damages the liver further
- Stop taking medications or supplements that stress the liver unless prescribed
- Eat a balanced diet rich in vegetables, lean proteins, and whole grains
- Antiviral medications for hepatitis B and C if the infection persists
- Vaccination for close contacts to prevent spread of hepatitis A and B
- Regular monitoring of liver function through blood tests
- See a doctor if symptoms worsen or jaundice develops

Frequently asked questions
The main differences are how they spread and how serious they become. Hepatitis A and E spread through contaminated food or water and usually resolve on their own. Hepatitis B, C, and D spread through blood and body fluids. Hepatitis B and C can become chronic and lead to long-term liver damage. Hepatitis D only infects people who already have hepatitis B.
Vaccines exist for hepatitis A and hepatitis B but not for hepatitis C, D, or E. The hepatitis A vaccine is given in two doses six months apart. The hepatitis B vaccine is typically given in three doses over six months. Since hepatitis D only occurs with hepatitis B, the hepatitis B vaccine also prevents hepatitis D.
People with ongoing risk factors should get tested at least once a year. This includes healthcare workers, people who inject drugs, and those with multiple sexual partners. If you traveled to areas where hepatitis is common or had a potential exposure, get tested right away. Regular testing with Rite Aid helps catch infections early when treatment works best.
Elevated ALT means liver cells are damaged and releasing this enzyme into your bloodstream. In acute viral hepatitis, ALT can rise 10 to 100 times higher than normal levels. High ALT does not always mean you have hepatitis, as other conditions can raise these levels too. Your doctor will order additional tests to determine the exact cause of liver inflammation.
