Hepatitis A virus is an acute infectious liver disease caused by hepatitis A virus (HAV). Hepatitis A is potentially contagious, so understanding the transmission lines of hepatitis A will help us have the most effective prevention to protect our health.

1. What is hepatitis A?

Hepatitis A virus causes hepatitis A virus (HAV), the only hepatitis A virus found in humans. Viral hepatitis A is usually an acute disease (the disease manifests it only for a certain period of time), does not progress to chronic. Acute hepatic impairment may occur, but the incidence is less than 1% of all cases. After curing the disease, the patient has a lifelong sustainable immunity (or can actively create immunity to prevent the disease through the use of a vaccine – the vaccine against hepatitis A). Currently, there is no specific treatment for hepatitis A.

2. Which way is hepatitis A transmitted?

Currently, the number of patients suffering from hepatitis A is on the rise. That's because we don't have effective disease prevention measures yet.

Hepatitis B, hepatitis C is transmitted by blood, mother to child and through sexual contact, while hepatitis A is transmitted mainly by the gastrointestinal tract, due to food and drink contaminated with hepatitis A virus. Food, water, supplies, or the hands of people exposed to virus A will become a source of viral infection. In addition, hepatitis A virus can also be found in swimming pools, in household items, personal items, in soil environments, water sources … In patients, hepatitis A virus is often found inside saliva, urine but most often still in waste.

When inge food containing hepatitis A virus will follow food, drinking water enters the body causing hepatitis, affecting the role of the liver. Given the current situation of "dirty" food, exposure to dirty food (which may include frozen and undercooked food) due to hepatitis A can occur at any time: planting, harvesting, processing, processing and even after cooking. Food or water pollution is more likely to occur in countries where hepatitis A is common and in areas with poor sanitation or poor personal hygiene. Hepatitis A virus can be inhabited in dirty foods, if we use these foods, this is the way to directly bring the virus into the body. They will create manifestations of the disease when conditions are favorable. The habit of using re-food is also the cause of hepatitis A

Hepatitis A can also be transmitted by blood, but transmission is rare.

The number of people with hepatitis A in Vietnam has been increasing in recent times. Currently, there is no specific treatment for hepatitis A, so the best way to prevent hepatitis A is to get vaccinated against hepatitis A.

3. How to prevent hepatitis A

The incidence of hepatitis A in developing countries is quite high. These are places where water and sanitation conditions are not guaranteed. Especially those with poor immune systems, children are susceptible to hepatitis A. Currently, there is no specific treatment for hepatitis A, so the best way to prevent hepatitis A is to get vaccinated against hepatitis A and good personal hygiene. Here are some ways to prevent hepatitis A:

Hepatitis A vaccination: The vaccine is about 95% effective in healthy adults and can last more than 20 years. It is about 85% effective in children and can last 15 to 20 years. This can only be effective when you are vaccinated. Children: first nose at 1 year to 15 years old dose 80 UI 2nd nose after first nose 6-12 months. Adults and children over 16 years of age: a dose of 160UI injects 2 shots, of which the second after the first 6-12 months.

Perform good personal hygiene – wash your hands after cleaning and before eating. When traveling to areas with circulating hepatitis A, avoiding drinking water, eating uncooked fruits or vegetables, cooked foods can still transmit the disease if they are contaminated after cooking. The virus is destroyed by boiling at 85 degrees Celsius (185 degrees 1) for 1 minute.

  • Ensure food hygiene and safety, eat boiled food, rinse food before processing
  • Wash your hands with soap before and after eating, after going to the toilet and processing food
  • Follow a proper diet and rest. Increase the iningment of plenty of greens and fresh fruits for nutritional supplements. It is also advisable to refrain from eating foods that are not beneficial to the liver such as hot spicy foods, high in grease, alcohol and stimulants.
  • Regularly practice physical exercise to improve health, help mental comfort, enhance liver detoxification
