Hepatitis A cases have increased across Thailand in early 2026, particularly in Bangkok and nearby provinces. Health authorities are advising residents and travelers to stay informed and take preventive measures.
This article explains what Hepatitis A is, how it spreads, symptoms to watch for, and how vaccination can help reduce your risk.
What is Hepatitis A?
Hepatitis A is a viral infection that affects the liver. It is typically spread through contaminated food, water, or close contact with an infected person.
Unlike Hepatitis B or C, Hepatitis A does not usually cause chronic liver disease, but it can still lead to significant illness, especially in adults.
How Hepatitis A Spreads
You can get infected through:
- Contaminated food or water
- Ice made from unsafe water
- Raw or undercooked seafood, such as oysters or cockles
- Poor hand hygiene
- Close contact with an infected person
Common Symptoms
Symptoms usually appear 2–6 weeks after exposure and may include:
- Fatigue
- Nausea or vomiting
- Loss of appetite
- Fever
- Abdominal discomfort
- Dark urine
- Yellowing of the skin or eyes, also known as jaundice
Some individuals, especially younger people, may have mild or no symptoms.
Who Should Be More Careful?
You may have a higher risk if you:
- Frequently eat raw seafood, street food, or food from unverified sources
- Travel within areas where Hepatitis A cases are increasing
- Work in food handling, hospitality, healthcare, or childcare
- Live in shared or high-density environments
- Have not been previously exposed to Hepatitis A or vaccinated
Prevention: Practical Steps
1. Food and Water Safety
- Choose freshly cooked, hot meals.
- Avoid raw or undercooked seafood.
- Use bottled or boiled water.
- Avoid ice from unknown or unverified sources.
2. Personal Hygiene
- Wash hands thoroughly before eating.
- Wash hands after using the restroom.
- Maintain proper sanitation practices at home and work.
3. Vaccination
Vaccination is a recognized preventive measure that can help reduce the risk of Hepatitis A infection.
Hepatitis A Vaccine: What to Know
- The Hepatitis A vaccine is typically given in 2 doses.
- It helps the body build protection against the virus.
- It may be recommended for adults without prior immunity.
- It may be recommended for food handlers, travelers, and people in higher-risk environments.
A healthcare professional should assess whether vaccination is appropriate for you based on your medical history, age, risk factors, and current health condition.
