What is Hepatitis A?

Hepatitis A is a liver infection caused by the Hepatitis A Virus (HAV). Unlike Hepatitis B or C, it doesn’t lead to chronic liver disease. Most people recover fully within weeks or months, though the illness can be uncomfortable during recovery due to liver inflammation.

While Singapore has made progress in public health, occasional cases of hepatitis still happen, often due to contaminated food or poor hygiene. Eating raw or undercooked seafood, like shellfish, can increase the risk of hepatitis and expose people to the virus.

A common myth is that Hepatitis A spreads through sneezing or coughing. In reality, it’s transmitted through poor hygiene or contaminated environments. The body produces an antibody to fight the virus, which helps most people recover.

Now, let’s look at how to recognize its symptoms.

Signs

Symptoms of Hepatitis A

Symptoms of Hepatitis A, an inflammation of the liver, can vary from mild discomfort to more severe symptoms. Some individuals remain entirely asymptomatic, which may inadvertently increase the risk of community spread

Early Symptoms
  • Fatigue and weakness
  • Fever and chills
  • Nausea, vomiting, or loss of appetite
  • Abdominal discomfort, especially on the upper right side
Advanced Symptoms
  • Jaundice (yellowing of the skin and eyes)
  • Dark-colored urine Pale stools
  • Persistent itching, which may indicate liver involvement

The challenge? These symptoms often resemble other illnesses, including hepatitis C. If you experience several of these at once—especially jaundice—it’s crucial to see a doctor for testing immediately. While there isn’t a specific treatment for Hepatitis A, rest, hydration, and supportive care can help manage the condition.

What About Silent Cases?

Many asymptomatic carriers unknowingly spread the virus through poor hygiene, such as not washing hands thoroughly after using the toilet. This is why immunization and prevention matter so much.

Causes

What Causes And Risk Factors of Hepatitis A?

Hepatitis A, an inflammation of the liver caused by the Hepatitis A Virus (HAV), is transmitted through the faecal-oral route, often by ingesting contaminated food or drinks.

High-Risk Environments and Activities
  • Consuming contaminated shellfish
  • Using untreated water, especially in regions with poor sewage-contaminated systems
  • Eating food prepared by infected individuals practicing poor personal hygiene
Groups at Higher Risk
  • Persons experiencing homelessness, who may have limited access to clean, sanitary conditions
  • Travelers visiting countries with high HAV prevalence
  • Workers in food-related industries without stringent hygiene practices

In severe cases, Hepatitis A can lead to acute liver failure, highlighting the importance of prevention and proper hygiene.

Virus

How is Hepatitis A Virus Transmitted?

Hepatitis A spreads through the fecal-oral route, meaning contact with even trace amounts of infected fecal matter can result in transmission. This doesn’t mean you’d have to eat fecal matter; it can be as simple as touching your mouth after using the toilet without thorough handwashing.

Common Transmission Methods
  1. Person-to-Person– Contact This includes situations where an infected individual prepares food for others without washing their hands properly.
  2. Contaminated Food and Water– Raw or undercooked shellfish is a frequent culprit, as is untreated water in regions with poor sanitation.

How

How to Prevent Viral Hepatitis A?

Prevention remains the most effective weapon against Hepatitis A. Here’s how you can safeguard yourself and others.

How-to-Prevent-Viral-Hepatitis-A
1. Vaccination

Hepatitis A vaccination is highly effective and is recommended for residents, travelers heading to high-risk areas, and anyone working in environments prone to exposure.

2. Practice Proper Hygiene
  • Handwashing Tips – Use soap and water, and scrub for at least 20 seconds, particularly after using the toilet or before eating food.
  • Avoid Sharing Utensils – Sharing utensils, plates, or glasses with someone infected can increase your risk.
3. Safe Food Practices
  • Avoid eating raw or undercooked seafood, especially in locations with questionable sanitary conditions.
  • Drink bottled or boiled water when traveling to areas with unsafe water supplies.

While there’s no specific cure for Hepatitis A, supportive care is often enough to manage symptoms as your body fights off the virus.

Treatment Options
  • Rest and adequate hydration are key to recovery.
  • Medications, such as anti-nausea drugs, can help manage symptoms.
  • Avoid alcohol or substances that strain your liver.
Recovery Timeline

Most people recover fully within a few weeks to months. Regular health screenings can help monitor liver function during recovery to reduce your likelihood of complications.

Hepatitis

Hepatitis A in Singapore

Efforts to combat Hepatitis A in Singapore focus on vaccinations and raising public awareness through health education. This strategy helps minimize the spread of the virus and protect public health. The virus is widespread and highly contagious, making prevention and early intervention critical.

Public Health Campaigns

The Ministry of Health leads campaigns to promote proper hygiene and the importance of vaccination. These efforts target high-risk groups like food handlers, who help prevent contamination, and travelers exposed to the virus in areas with poor sanitation. Schools, community centers, and healthcare facilities serve as key platforms for public education on Hepatitis A prevention, including recognizing symptoms that might require treatment. Hepatitis A causes inflammation of the liver, and early identification through markers like IgM anti-HAV is essential for effective management.

Local Foods and Risk Factors

Singaporeans love seafood, but some dishes like half-boiled shellfish or raw seafood can carry risks if not properly prepared. Vaccination and strict food safety measures are essential in reducing these risks. Authorities also advise avoiding undercooked or poorly handled food to lower infection chances. While vaccination is effective, it’s important to note that comparable side effects like soreness at the injection site or mild fever may accompany the shot.

Vaccination Guidelines

Vaccination is one of the most effective ways to prevent Hepatitis A. It’s recommended for residents and travelers visiting regions with outbreaks or poor hygiene. Those consuming high-risk foods or working in fields like food service or healthcare are strongly encouraged to get vaccinated. The vaccine provides long-lasting protection, making it a key step in controlling the disease. For individuals who contract the virus, hepatitis A treatment focuses on managing symptoms and supporting the liver through recovery.

FAQ

FAQ on Hepatitis A

How is Hepatitis A transmitted?

Hepatitis A is primarily transmitted through ingestion of the virus from contaminated food or water. Key points of transmission include:

  • Fecal-Oral Route: The virus is excreted in the feces of infected individuals and can contaminate food or water that others consume.
  • Close Personal Contact: Direct contact with an infected person, such as caring for someone who is ill or through sexual contact, can spread the virus.
  • Consumption of Contaminated Food or Water: Eating food or drinking water that has been contaminated with the virus, often due to improper handling or poor sanitation, can lead to infection.

Symptoms of Hepatitis A can range from mild to severe and typically appear two to three weeks after exposure to the virus. Common symptoms include:

  • Fatigue
  • Sudden nausea and vomiting
  • Abdominal pain or discomfort, especially near the liver
  • Clay-colored bowel movements
  • Loss of appetite
  • Low-grade fever
  • Dark urine
  • Joint pain
  • Yellowing of the skin and eyes (jaundice)

Hepatitis A generally does not cause chronic liver disease, but it can lead to severe complications, particularly in older adults and individuals with preexisting liver conditions. Complications can include:

  • Acute liver failure (rare but serious)
  • Prolonged symptoms, lasting several months

Hepatitis A is diagnosed through a combination of medical history, physical examination, and blood tests, including:

  • Blood Tests: To detect antibodies against the Hepatitis A virus (anti-HAV IgM and IgG).
  • Liver Function Tests: To assess liver function and damage.

There is no specific treatment for Hepatitis A. Management focuses on supportive care to relieve symptoms. Recommended steps include:

  • Rest: Allow the body to fight off the infection.
  • Hydration: Drink plenty of fluids to stay hydrated.
  • Nutritional Support: Eat a balanced diet to support recovery.
  • Avoid Alcohol: Refrain from drinking alcohol to prevent further liver damage.
  • Medication: Avoid medications that can harm the liver unless prescribed by a healthcare provider.

Hepatitis A can be prevented through various methods:

  • Vaccination: An effective vaccine is available and is the best way to prevent Hepatitis A. It is recommended for all children, travelers to areas with high rates of Hepatitis A, and individuals at high risk.
  • Hand Hygiene: Wash hands thoroughly with soap and water, especially after using the bathroom, changing diapers, and before preparing or eating food.
  • Safe Food and Water Practices: Avoid consuming raw or undercooked foods and drink bottled or boiled water in areas with poor sanitation.
  • Avoid Close Contact: Avoid close personal contact with individuals who have Hepatitis A, especially during their contagious period.
