Hepatitis is a condition where the liver becomes inflamed. It can be caused by viruses, toxins, alcohol, certain medicines, or even the body’s own immune system attacking the liver.


If not treated, hepatitis can lead to serious problems like liver damage, cirrhosis (scarring of the liver), or liver cancer. In Indonesia, hepatitis is a significant public health issue.


Many people don’t know they have the virus until symptoms appear or liver damage has already happened. The World Health Organization estimates that more than 20 million Indonesians are living with hepatitis B or C, many without a diagnosis or treatment.


Hepatitis B is the most common type in Indonesia. Some areas, such as Maluku and Bangka Belitung, have infection rates above 20%.


Understanding the different types of hepatitis and how to prevent them is an important step in protecting yourself and your loved ones. Below are the five main types of hepatitis, what causes them, and how you can lower your risk.


1. Hepatitis A (HAV)


Hepatitis A (HAV) caused by contaminated food or water spreads through the “fecal-oral” route. This often happens in places with poor sanitation or hygiene, making clean eating and drinking habits very important.


Risk


Hepatitis A is widespread, with outbreaks often reported in crowded areas and tourist destinations. Bali, for example, has higher exposure risk due to its popularity and the movement of people and imported food.


Symptoms


  • Sudden tiredness
  • Fever
  • Loss of appetite
  • Yellowing of skin and eyes (jaundice)
  • Nausea and stomach pain


Prevention


  • Get vaccinated, hepatitis A vaccines are highly effective
  • Drink bottled or filtered water
  • Wash hands before eating and after using the toilet
  • Avoid raw or undercooked food in high-risk areas


If you’re traveling to Bali, getting a hepatitis A vaccine is strongly recommended.


2. Hepatitis B (HBV)


Hepatitis B (HBV) caused by contact with infected blood or body fluids can spread in several ways. This includes unprotected sex, sharing needles, or a mother passing it to her baby during childbirth.


Prevalence in Indonesia


Indonesia has one of the highest rates of hepatitis B in Southeast Asia. Many people don’t know they are infected, which increases the risk of spreading it to others.


Symptoms


  • Persistent tiredness
  • Joint or abdominal pain
  • Yellow skin and eyes
  • Loss of appetite
  • Dark urine


Complications


Chronic hepatitis B can lead to liver scarring (fibrosis), cirrhosis, or liver cancer. It is one of the main causes of liver-related deaths in Indonesia.


Prevention


  • Get vaccinated, safe, effective, and part of Indonesia’s national immunization program
  • Avoid sharing personal hygiene items
  • Use protection during sex
  • Ensure sterile equipment is used for tattoos, piercings, or medical procedures

3. Hepatitis C (HCV)


Hepatitis C (HCV) is caused by a virus that spreads through direct blood contact, often from sharing needles, unsafe medical practices, or receiving unscreened blood transfusions. It’s important to avoid exposure to infected blood to prevent getting HCV.


Symptoms


Many people have no symptoms for years. When they do appear, they may include:


  • Fatigue
  • Nausea
  • Muscle and joint pain
  • Yellow skin and eyes


Risk


Chronic hepatitis C can slowly damage the liver without obvious warning signs, eventually leading to cirrhosis or liver cancer.


Prevention


  • Use sterile needles and medical equipment
  • Ensure all blood products are screened before transfusion
  • Avoid sharing razors, nail clippers, or toothbrushes


Treatment


There’s no vaccine yet, but modern antiviral medicines can cure most cases when detected early.


4. Hepatitis D (HDV)


Hepatitis D (HDV) is caused by a virus that only affects people already infected with hepatitis B, as it needs the hepatitis B virus to multiply in the body. This means you can only get HDV if you already have or are exposed to hepatitis B.


Symptoms


  • More severe illness compared to hepatitis B alone
  • Faster liver damage and higher risk of complications


Prevention


  • Vaccination against hepatitis B also protects against hepatitis D
  • Follow all hepatitis B prevention steps


If you’re vaccinated for hepatitis B, you’re also safe from hepatitis D.


5. Hepatitis E (HEV)


Hepatitis E (HEV) is caused by a virus that spreads through contaminated water, especially in areas with poor sanitation or during floods and natural disasters. To avoid infection, it’s important to drink clean, safe water and practice good hygiene.


Outbreaks in Indonesia


Cases have been reported in West Kalimantan and East Java. Pregnant women are at higher risk of severe illness.


Symptoms


  • Mild fever
  • Jaundice
  • Loss of appetite
  • Stomach discomfort


Prevention


  • Boil or filter drinking water
  • Practice good food hygiene
  • Wash hands before eating and after using the bathroom


Hepatitis E often clears on its own, but it can be life-threatening during pregnancy.


Other Causes of Hepatitis


Not all hepatitis comes from viruses. Other causes include:


  • Autoimmune hepatitis: when the immune system attacks the liver
  • Alcoholic hepatitis: due to long-term heavy drinking
  • Drug-induced hepatitis: triggered by certain medicines or supplements


In all cases, avoiding known triggers and seeking medical advice early can help prevent permanent liver damage.
