Recently, topics related to hemorrhagic fever have been on the hot search list of social media and attracted attention. Rumors from "mice eating strawberries everywhere lead to hemorrhagic fever" to "eating strawberries lead to hemorrhagic fever", once made strawberries lie on the gun. What is hemorrhagic fever? Who spread hemorrhagic fever? Can you get hemorrhagic fever by eating strawberries? In view of the recent reports of hemorrhagic fever in many places, experts from the Beijing CDC said that the "Mastermind" of the disease is actually it. It is important to understand the knowledge of prevention. No more than 10 cases per year in Beijing Epidemic hemorrhagic fever, also known as hemorrhagic fever with renal syndrome in the world, is a serious acute infectious disease transmitted by rats and caused by hantavirus. Clinically, it is characterized by fever, bleeding and renal damage. The population is generally susceptible, and the case fatality rate is about 1%. It is understood that China is a big country with hemorrhagic fever with renal syndrome, and 90% of the global cases occur in China. China first discovered the disease in 1931 and listed it as a class B legal infectious disease in 1956. Most areas have different degrees of disease or epidemic every year. Beijing is dominated by house mice, and the number of cases is less than 10 every year in recent years. Most people only have fever, which is easy to be confused with a cold After infection with hantavirus, more than 80% of people will have dominant disease. Typical cases have five stages of clinical course, that is, the main manifestations are fever, systemic poisoning symptoms, capillary injury symptoms and kidney damage. Sun Yulan, deputy chief technician of the Communication Institute of the Municipal Center for Disease Control and prevention, introduced that the symptoms of systemic poisoning are systemic pain, headache, low back pain and orbital pain. Generally, headache, low back pain and orbital pain are called "three pains"; The main manifestations of capillary injury were congestion, bleeding, exudation and edema. Skin congestion is common in the face, neck and upper chest. Skin congestion and flushing, namely "three redness". However, most cases have mild symptoms, only mild symptoms such as fever, which are easy to be confused with colds. At present, there are no specific drugs for the treatment of hemorrhagic fever with renal syndrome, mostly supportive treatment. As long as patients achieve "three early and one on": early detection, early rest, early treatment and nearby treatment, most people have a good prognosis. Hemorrhagic fever is transmitted to people by it Sun Yulan introduced that people are not the source of infection. It is generally believed that hemorrhagic fever with renal syndrome will not be transmitted from person to person. The disease itself is not directly related to eating strawberries. Mice with virus are the "culprit". According to different host species, hemorrhagic fever with renal syndrome can be divided into Apodemus agrarius (transmitted by Apodemus agrarius) and house mouse (transmitted by Rattus norvegicus). The condition of Apodemus agrarius is more serious, the peak season of incidence is autumn and winter, and the house mouse type is relatively light, and the incidence is mostly in spring. There are three main routes of transmission of hemorrhagic fever with renal syndrome: It is transmitted from mice with virus to human. Mice bite human skin or mouse urine, feces and saliva pollute human damaged skin and mucosa; Rat urine, feces and saliva pollute food; When the dust polluted by rat urine, feces and saliva is raised, it is inhaled into human respiratory tract. Mites parasitic on mice or holes bite people. The incubation period of mother to child vertical transmission is usually 7 to 14 days, and occasionally as short as 4 days or as long as 2 months. Mastering the prevention method, hemorrhagic fever is not terrible Deratization and prevention of hemorrhagic fever with renal syndrome is a natural focal disease mainly transmitted by rodents. Deratization and prevention is a successful experience and main measure for the prevention and treatment of hemorrhagic fever with renal syndrome. Clean the environment and do a good job in indoor and outdoor sanitation. Keep the room dry and ventilated, and keep no sundries and food under the bed; Timely remove accumulated garbage; Killing and preventing mites. Do not provide breeding space for rats, and clean the sundry room regularly; During the cleaning process, pay attention to wear masks and gloves and do a good job of disinfection. Prevent diseases from entering through the mouth and do a good job in food hygiene, tableware disinfection and food preservation; Grain and food shall be stored in tight and seamless containers and covered to prevent rat pollution. Do not store them exposed; Do not eat vegetables, fruits and other foods bitten by rats. Pay attention to protection in the field. Do not directly contact rats and their excreta by hand. Do not sit on the grass or haystack. Pay attention to protect the skin from damage or mite bites. Vaccination of hemorrhagic fever vaccine China has developed a bivalent inactivated vaccine against hemorrhagic fever with renal syndrome, which is the most economical and effective measure to prevent hemorrhagic fever.
