What is hepatitis A?

 Hepatitis A is hepatitis caused by the virus. Hepatitis A is not transmitted through blood, such as hepatitis B or hepatitis C, but by consuming food or water contaminated with the hepatitis A virus. In particular, there are many cases in underdeveloped countries with poor personal hygiene management, but recently, the incidence has also increased sharply in people in their 20s and 30s who grew up in a hygienic environment.



Importantly, it can be transmitted to the fetus in the course of childbirth by a parent with hepatitis A, which is not a direct cause, and by non-permanent infections such as male homosexuals or others.

In most cases, the infection is caused by ingestion of water or food contaminated with the feces of the infected person, and the outbreak occurs in groups due to contaminated drinking water sources or school meals.


- hepatitis A symptoms

It appears in the form of acute hepatitis.

When infected with the hepatitis A virus, primary systemic symptoms such as fatigue, nausea, sluggish appetite, fever, and pain in the right upper abdomen appear after a 30-day incubation period.

Within a week, characteristic signs of jaundice appear, including symptoms such as black urine (cola urine), bleached feces, and itchy whole body. If jaundice occurs, the previous systemic symptoms will disappear, and the symptoms will last for about two weeks. In children, even if symptoms are asymptomatic or mild, they often pass by unconsciously.


- Treatment of hepatitis A

No medication has been developed to treat hepatitis A virus. In general, hyperplasia is the main treatment to relieve symptoms, and a high-protein diet and liver rest are helpful for treatment. In cases where severe symptoms are accompanied, hospitalization can be treated to relieve the symptoms.


- Prevention methods

There is a vaccine for hepatitis A. Usually, depending on the type of vaccine after a single vaccination, additional inoculation can be performed 6-12 months later or 6-18 months later to prevent hepatitis by more than 95%. It works not only for children over the age of two but also for adults who have not yet been exposed to the virus. The side effects of the vaccine are localized, such as fever, headache, and release of the injection site.

  Because hepatitis A is an oral infection from feces, personal hygiene management is the most important. In general, hepatitis A virus disappears even if heated for one minute above 85 degrees Celsius, so it can be prevented by drinking boiled water or eating fully cooked food.

Just as personal hygiene is important as it is now, hepatitis A is also important to prevent it from washing your hands clean after using the bathroom or when you go out.
