Hepatitis A is a liver disease caused by the hepatitis A virus.

How Does Hepatitis A Spread?

The hepatitis A virus is primarily transmitted through the fecal-oral route, meaning it spreads by contact with or ingestion of items, food, or water contaminated by an infected person’s feces. Additionally, close contact or sexual contact with an infected individual (not limited to anal contact) can also lead to infection. Water sources contaminated by sewage or inadequately treated water can also transmit hepatitis A.

Symptoms of Hepatitis A

The incubation period for hepatitis A typically ranges from 14 to 28 days. After infection, common symptoms include fever, nausea, diarrhea, fatigue, abdominal discomfort, and jaundice. Patients often require several weeks or even months to recover.

Severity of Hepatitis A

Hepatitis A infection does not progress to chronic hepatitis, but the hepatitis A virus can potentially cause acute fulminant hepatitis, which has a high mortality rate.

Hepatitis A Vaccine: An Effective Way to Prevent Infection

The hepatitis A vaccine (甲型肝炎疫苗) can effectively prevent infection with the hepatitis A virus.

What You Need to Know About the Hepatitis A Vaccine:

• Dosage: The hepatitis A vaccine requires two doses.
• Vaccination Schedule: The second dose should be administered 6 to 18 months after the first dose.
• Safety: The hepatitis A vaccine is very safe, with common side effects including pain and redness at the injection site.

Pre-Vaccination Blood Test:

Before receiving the hepatitis A vaccine, a blood test can be conducted. If the body already has hepatitis A antibodies, it indicates immunity to hepatitis A, meaning vaccination is not necessary.

Conclusion

Hepatitis A is a disease that can cause significant harm to the liver. Vaccination with the hepatitis A vaccine is an effective way to prevent hepatitis A. To protect your health, consult a doctor to learn more about the hepatitis A vaccine.
