How does hepatitis a spread

summary

Hepatitis A is a kind of liver disease, which can be infected. I believe we all know that its harm is great. It not only does harm to our own health, but also may bring trouble to our family and friends. A few days ago, I saw the outbreak of hepatitis A in the United States on the news, and many people were affected. So I watched how hepatitis a spread on the Internet, hoping to avoid infection. Let's share it with you.

How does hepatitis a spread

First: water source transmission: This is the main mode of transmission of hepatitis A outbreak, which mostly occurs after rainstorm and rainy season. Patients' feces, saliva, vomit and other excreta come to the surrounding environment, especially the water source, due to the washing pollution of rainwater. In rural areas with poor sanitary conditions, due to the lack of tap water facilities, people often use well water, river water or pond water. When the body's resistance is weakened and the polluted water is drunk, it is very easy to cause infection and outbreak.

Second: food transmission: it is mainly caused by eating contaminated food, especially raw fruits and vegetables without cooking, or semi cooked shellfish products such as oysters, clams, clams and clams.

Third: daily life contact transmission: This is the main mode of transmission of hepatitis A, also known as indirect transmission. It is mainly transmitted through the mouth of contaminated food such as hands, tableware, utensils and toys.

matters needing attention

It is found that many of the patients with hepatitis A have the bad habit of keeping long nails. When the nails grow, they don't pay attention to hygiene. They count money with the long nails contaminated by hepatitis A virus, exploit the peel, shave teeth with toothpick and ingest food. It is very easy to bring pathogens into the mouth and get infected with hepatitis A virus.
