The five types of hepatitis and their common causes

July 24, 2023
​Hepatitis remains one of the common causes of death in Malaysia. This condition involves the inflammation of the liver and is primarily caused by viral infections. There are five main types of hepatitis, with Hepatitis A, B, and C being the most common forms.

Hepatitis A is known for its transmission through the consumption of contaminated food or water. University of Malaya Faculty of Medicine Professor Dr Rosmawati Mohamed highlights that Hepatitis A can be transmitted through the consumption of cockles and oysters. However, it is important to note that not all seafood carries the risk of transmission. While Hepatitis A causes short-term effects, the chances of recurrence are relatively low.

Hepatitis B and C are primarily transmitted through blood and body fluids, most commonly through unprotected sexual contact, sharing of needles, and from mother to child during childbirth. These forms of hepatitis can lead to chronic infections and potentially severe long-term consequences for liver health if left untreated.

Comprehensive management and preventive measures
Understanding the differences between the types of hepatitis is crucial for effective prevention and management. Proper education and awareness are essential in preventing the spread of the disease and ensuring the safety of the public.

The management of hepatitis involves a multidisciplinary approach, including early diagnosis, regular monitoring, and appropriate medical interventions. Vaccination against Hepatitis A and B is available and strongly recommended, especially for high-risk groups. Hepatitis C can now be effectively treated with antiviral medications, offering hope for patients living with chronic infections.

Additionally, practicing safe sex, avoiding sharing personal items such as razors and toothbrushes, and ensuring proper sterilization of medical equipment can significantly reduce the risk of hepatitis transmission.

While Hepatitis A can be transmitted through specific foods like cockles and oysters, it is essential to remember that they are safe for consumption when prepared and sourced properly. Maintaining good hygiene practices while handling and preparing food can further minimize the risk of foodborne transmission.
