Contact and communication in daily life

This is one of the most common forms of infection. It is spread through indirect things such as food and toys. Don't use things used by strangers. This is a way of self-protection. In recent years, it has been found that many patients with hepatitis A have the bad habit of long nails. Don't pay attention to hygiene when nails grow out. They count money with long nails infected with hepatitis A virus, exploit peels, scrape teeth with toothpicks and eat food. And it is easy to bring pathogens into the mouth and infect hepatitis A virus.

Water source transmission

This is the main mode of transmission leading to the outbreak of hepatitis A, which mostly occurs after heavy rain and rainy season. The patient's feces, saliva, vomit and other excreta pollute the surrounding environment, especially the water source. In rural areas with poor sanitation, people often use well water, river water or pond water because there is no running water facilities. When the body's resistance is weakened and polluted water is drunk, it is easy to cause infection and outbreak.

Food transmission

It is mainly caused by eating contaminated food, especially uncooked fruits and vegetables, or semi-cooked shellfish such as oysters, clams, clams, etc. Flies and cockroaches are also important vectors of the disease.

How to prevent hepatitis A correctly

1, to prevent hepatitis A, we must first develop good hygiene habits and control "disease from mouth to mouth". Wash your hands before and after meals, don't drink raw water, and don't eat or eat less cold food. When eating fruits, lettuce and other fruits and vegetables, be sure to clean them.

2. In addition, people with fever accompanied by fatigue, anorexia, nausea, vomiting, jaundice and other symptoms should go to the hospital intestinal clinic in time to achieve "early diagnosis, early report, early isolation and early treatment", which is of great significance to control the epidemic situation of hepatitis A.

3. Leftover food should be stored in the refrigerator and fully heated before eating again. For some foods that are easy to carry viruses, such as shellfish, clams and other aquatic products, they must be cooked and steamed thoroughly when eating. Generally speaking, heating at 100℃ for one minute can inactivate hepatitis A virus. Therefore, the prevention of hepatitis A leftovers needs to be thoroughly eaten.

Hot pot is a popular food all year round, and it always attracts many diners in summer. However, eating hot pot is another culprit leading to hepatitis A. Hot pot dishes are rich, generally including pigs, cattle, mutton, various animal offal, seafood and vegetables.

Because there are more ingredients, there are more pathogens. Therefore, in order to prevent hepatitis A, the ingredients of hot pot must be clean and hygienic, and vegetables and meat must be washed before eating; Don't blindly pursue crispness when scalding food. For the sake of safety, pork slices, venetian blinds, yellow throats and beef venetian blinds are best cooked in a pot for a long time, and seafood such as shellfish, oysters and snails should be rinsed clean.

5. It is best to wash your hands with alkaline soap. Spring and summer are the seasons with the highest incidence of hepatitis A throughout the year. Hepatitis A is easy to be misdiagnosed and infected, so special attention should be paid to prevention and treatment. Hepatitis A is mainly transmitted through the digestive tract. People who are in close contact with hepatitis A patients will be infected if they use tableware, teacups, toothbrushes and other daily necessities, or eat food contaminated by hepatitis A virus and drink water infected by hepatitis A virus.

The key to prevent hepatitis A is to keep the entrance closed, pay attention to food hygiene, and develop good habits such as not drinking raw water, not eating unfamiliar and unclean food, and washing hands with alkaline soap and tap water before and after meals. Maintaining a comfortable mood and optimistic attitude is very beneficial to the prevention and treatment of liver disease.

6. Physical examination cannot be a slogan. Early liver disease often has no symptoms and is not easy to be detected by patients. The clinical symptoms of patients with liver disease are different, and the time and degree of each symptom often vary from person to person. Not every symptom will appear, but there are common clinical symptoms: loss of appetite, fatigue, discomfort and pain in the right upper abdomen, abdominal distension, nausea and so on. Therefore, if there is a problem, you must go to the hospital for examination in time.

7, we must pay attention to eliminate flies and other pests, they may be used as a vector of infectious diseases, so we must pay attention to hygiene and avoid the harassment of these insects.

8. Be sure to vaccinate hepatitis A vaccine in time, which can not only improve the immunity of the population, but also reassure family members, especially some children, to vaccinate early.

9. Don't eat in small restaurants or street vendors with insufficient sanitary facilities.
