In spring, seafood is available in large quantities, and raw seafood is welcomed by many people. Shandong Provincial Hospital experts pointed out that spring is the period of hepatitis A and E, raw seafood is easy to infect these two liver diseases. Shandong Provincial Hospital has recently received six or seven consecutive patients infected with hepatitis A and E due to raw seafood. According to the hospital’s deputy chief physician of the Department of Hepatology, Korean Qing, hepatitis A and E are mostly caused by food, especially seafood. Among the seafood, shellfish is the most dangerous, and it is best to cook it before entering. The initial symptoms of hepatitis A and E patients are often feverish, weakness and loss of appetite, and because these symptoms are similar to the flu, many patients are treated as a common cold, which not only delays treatment but also increases the likelihood of infecting others, said Han Kheng. Experts suggest that eating cooked food, not raw seafood, and washing hands can effectively prevent hepatitis A and E. Also, if you have unexplained fever and pain in the liver area after eating raw food for a period of time, you must go to the hospital for liver function tests in a timely manner. According to the results released by the Ministry of Health in February 2008, the national incidence of hepatitis A and E in 2007 was 3,592 and 1,695 cases, with one and two deaths respectively. These two types of hepatitis are not terrible, and the proportion of the population is very small, the death rate is not high, and they can basically be cured after treatment. The vaccine is also an important tool to prevent these two liver diseases. It is understood that although there is no vaccine for hepatitis E for the time being, it can be effectively prevented by simple measures such as eating cooked food and especially washing hands regularly. In February this year, the Ministry of Health formulated an expanded national immunization program to include hepatitis A vaccine in the national immunization program, requiring routine vaccination of school-age children.
