Transmission routes of hepatitis A

Hepatitis A is also called hepatitis A. It is the hepatitis A virus that can cause this disease. If you have hepatitis A, you will have symptoms such as loss of appetite, fatigue, abnormal liver function, and an enlarged liver. Some patients will have symptoms of jaundice. The main manifestation is acute hepatitis. People of any age may suffer from hepatitis A, and hepatitis A is highly contagious. Everyone should understand the transmission routes of hepatitis A.

There are many ways of transmitting hepatitis A. This disease is now very common all over the world, especially among children and adolescents, who are the main groups affected. If adults are infected with hepatitis A, the symptoms will be more serious, so everyone should take precautions.

In response to this issue, experts said that the hepatitis A virus is mainly excreted from the body through feces and transmitted through the fecal-oral route. There are several ways of transmission: 1. Transmission through contact in daily life. This is the main way of transmission of hepatitis A, also called indirect transmission. The infection is mainly transmitted through hands, tableware, utensils and toys contaminated with hepatitis A virus, which then contaminate food and are transmitted through the mouth. This method often occurs in collective units such as schools, kindergartens, military units, factories, and families, so it can cause epidemics as well as sporadic cases.

2. Waterborne transmission is the main mode of transmission that causes outbreaks of hepatitis A, and it often occurs after heavy rains and rainy seasons. The patient's feces, saliva, vomit and other excrement can pollute the surrounding environment, especially water sources, due to the washing of rainwater. In rural areas with poor sanitary conditions, there are no running water facilities and people mostly drink well, river or pond water. When the body's resistance is weakened and they drink contaminated water, it is very easy to get infected and cause an epidemic outbreak.

3. Food transmission is mainly caused by eating food contaminated with hepatitis A virus (especially raw fruits and vegetables, or uncooked shellfish such as oysters, clams and razor clams). In addition, there have been frequent reports of outbreaks caused by food contamination by food workers infected with hepatitis A. The incubation period of the epidemic caused by this mode of transmission is usually relatively short, and the patients are in more serious condition. 4. Other flies and cockroaches are also important vectors of the disease. Transmission by blood-sucking arthropods, air droplets, vertical transmission from mother to child, and sexual contact cannot be confirmed for the time being because they have not been confirmed or reported.

Knowing the transmission routes of hepatitis A can effectively prevent the spread of this disease. If there are people around you who have hepatitis, you should stay away from them. Hepatitis A now has a very high incidence rate, especially in winter and spring, which is the peak season for hepatitis A. In this season, everyone should take some precautions in advance to avoid being infected with hepatitis.
