Hepatitis A

Hepatitis A is a contagious liver disease caused by the hepatitis A virus (HAV). It is spread through contact with an infected person's feces (stool) or through contaminated food or water. It is most common in areas with poor sanitation and can cause mild to severe illness. Most people recover completely with no long-term health problems.

Transmission

Hepatitis A is spread through contact with an infected person's feces (stool) or through contaminated food or water. It can also be spread through close contact with an infected person, such as through sexual contact or household contact. It is not spread through breast milk, blood transfusions, or sharing eating utensils.

Prevention

The best way to prevent hepatitis A is to get vaccinated. The hepatitis A vaccine is safe and effective and is recommended for all children at age 1 year, and for adults at risk for hepatitis A. Other preventive measures include washing hands with soap and water after using the bathroom, changing diapers, and before preparing food; avoiding contaminated food and water; and avoiding close contact with people who are infected.

Diagnosis

Hepatitis A is usually diagnosed based on a physical exam, medical history, and blood tests. Blood tests can detect antibodies to the virus, which indicate that a person has been infected with hepatitis A.

Outlook

Most people recover completely from hepatitis A with no long-term health problems. In rare cases, hepatitis A can cause liver failure and death. People with weakened immune systems, such as those with HIV or other chronic liver diseases, are at higher risk for more severe illness.

• Fever
• Fatigue
• Loss of appetite
• Nausea and vomiting
• Abdominal pain
• Dark urine
• Clay-colored bowel movements
• Joint pain
• Jaundice (yellowing of the skin and eyes)

In some cases, people with hepatitis A may not have any symptoms at all. If symptoms do occur, they usually last for several weeks, but can last up to 6 months. Most people recover completely without any long-term health problems.

Common Causes of Hepatitis A

• Eating food or drinking water contaminated with the virus
• Close contact with an infected person, such as through certain types of sexual contact
• Using contaminated needles or syringes
• Living in or traveling to areas with poor sanitation

Risk Factors for Hepatitis A

Certain factors can increase your risk of getting hepatitis A, including:

• Living in or traveling to areas with poor sanitation
• Having close contact with someone who has hepatitis A
• Having a weakened immune system due to HIV/AIDS, cancer, or other conditions
• Using recreational drugs
• Having a job that involves contact with the public, such as food service or healthcare

Preventing Hepatitis A

The best way to prevent hepatitis A is to get vaccinated. The hepatitis A vaccine is safe and effective, and it is recommended for all children and adults. It is also recommended for people who are at increased risk of getting the virus, such as those who travel to areas with poor sanitation, those who have close contact with someone who has hepatitis A, and those who use recreational drugs.

Clinical Symptoms

The most common symptoms of hepatitis A include jaundice (yellowing of the skin and eyes), fatigue, abdominal pain, nausea, and loss of appetite. Other symptoms may include dark urine, light-colored stools, and fever.

Laboratory Tests

Laboratory tests are used to confirm the diagnosis of hepatitis A. These tests include a blood test to measure levels of liver enzymes, such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Other tests may include a hepatitis A antibody test, a hepatitis A virus (HAV) test, and a hepatitis A virus RNA test.

Imaging Studies

Imaging studies, such as an ultrasound or CT scan, may be used to assess the extent of liver damage caused by hepatitis A. These studies can also help to identify any complications, such as cirrhosis or liver cancer.

Treatment

Treatment for hepatitis A is usually supportive and includes rest, fluids, and a healthy diet. In some cases, antiviral medications may be prescribed to reduce the severity of symptoms. Vaccination is the best way to prevent hepatitis A.

Symptoms

The most common symptoms of hepatitis A include fever, fatigue, loss of appetite, nausea, vomiting, abdominal pain, dark urine, clay-colored stools, joint pain, and jaundice (yellowing of the skin and eyes). It is important to discuss any symptoms you may be experiencing with your doctor.

Diagnosis

Your doctor may order a blood test to diagnose hepatitis A. The test looks for antibodies to the virus, which can indicate an active or past infection. Your doctor may also order a liver function test to check for any damage to the liver.

Treatment

There is no specific treatment for hepatitis A. Most people recover on their own within a few weeks. Your doctor may recommend rest, fluids, and over-the-counter medications to help relieve symptoms. In some cases, your doctor may prescribe antiviral medications to help reduce the severity of the infection.
