Hepatitis B causes 6.5438+0.4 million deaths every year. How to prevent and control hepatitis B?

Hepatitis B is the abbreviation of chronic hepatitis B, which mainly refers to people who are positive for chronic hepatitis B virus, with a course of more than half a year or an unknown onset date, and whose clinical manifestations are chronic hepatitis. The clinical manifestations of patients with hepatitis B are fatigue, aversion to food, nausea, abdominal distension, pain in liver area and other symptoms. At the same time, the patient's liver is large, with moderate hardness and mild tenderness. For patients with serious illness, it may also be accompanied by chronic liver disease, spider nevus, hepatopalmar swelling, spleen swelling, abnormal liver function or persistent existence. According to the clinical manifestations, it is divided into mild, moderate and severe.

According to relevant data, there are about 70 million patients with hepatitis B in China, and more than 90% of them have not received any treatment. Besides China, hepatitis B and hepatitis C are also a global problem. Hepatitis B and hepatitis C affect 325 million people worldwide, resulting in 65.438+0.4 million deaths every year. In fact, in the "20 19 National Survey of Legal Infectious Diseases" released by National Health Commission, we can know that viral hepatitis is still the first class B infectious disease in China. It is worth mentioning that according to the data of the Health and Health Commission, at least 30 million people are infected with hepatitis B every year due to the expansion of the hepatitis B vaccine program. Although 70 million people are infected with hepatitis B, only 20 million to 30 million people really need treatment, and among these people, only 18% can really diagnose hepatitis B. In fact, there are reasons for the low diagnosis rate and treatment rate of hepatitis B, and the most important reason is lack of understanding. Many people have no idea that they have hepatitis B. ..

Relevant data show that 80% of liver cancer patients in China are related to hepatitis B, and more than 300,000 patients in China die of liver cancer due to cirrhosis every year. In fact, through effective and standardized nucleoside drugs and interferon antiviral treatment for hepatitis B patients, the number of deaths can be reduced by at least 50%. Therefore, many experts advocate that ordinary people should be diagnosed and treated early to reduce the incidence of serious liver diseases such as cirrhosis and liver cancer. Then, in our daily life, how should we prevent hepatitis B? It's actually very simple. Mainly have the following preventive measures:

First, cut off the transmission route of liver disease. Try to stay away from all kinds of appliances that may be infected by blood, and generally don't share toothbrushes and razors with others.

Second, maintain a balanced nutrition. In daily life, we must keep a balanced diet and keep our weight within a reasonable range, not too fat or too thin.

Third, prevent overwork. Heavy physical and mental work will make the body in an overloaded state, which is not conducive to the human immune system. When human immunity declines, liver disease viruses will multiply in large numbers, which is not conducive to health.

Fourth, vaccinate. Hepatitis vaccine is very safe, and the prevention success rate is over 90%. Therefore, for middle-aged and elderly people, we should actively play hepatitis vaccine. For patients with poor liver, pay attention to the combination of prevention and treatment.
