Hemorrhagic fever is not plague, although both are natural epidemic diseases, the main source of infection is rodents, but the cause, symptoms, as well as the level of infectious disease, treatment measures, etc. are not the same, can be identified by the following aspects. However, both hemorrhagic fever and plague should be taken seriously and self-protection should be done, and active treatment is required if the disease is inadvertently contracted.1. Etiology: Hemorrhagic fever is a disease caused by rodent-borne hantavirus. The plague is a virulent infectious disease caused by Yersinia pestis, mainly prevalent in rodents, otters and other rodents. 2. Symptoms: The incubation period of hemorrhagic fever is usually 7-14 days, and most patients have a rapid onset, with clinical manifestations of fever 39-40°C, generalized mucosal congestion, hemorrhage, hypotension, shock, and oliguria or even anuria. The incubation period of plague is 2-5 days, with rapid onset and clinical manifestations mainly include high fever 39-41℃, severe headache, chills, chills, swollen lymph nodes, and symptoms such as coughing, coughing up bloody sputum and shortness of breath can be seen in pneumonic plague. 3. Infectious disease level: Hemorrhagic fever belongs to category B infectious disease, and through early detection and treatment, a better prognosis can be obtained, but plague belongs to category A infectious disease, and compared with hemorrhagic fever, it is It is more contagious and has a relatively higher death rate. 4. Treatment: Hemorrhagic fever is mainly treated symptomatically, and there is a lack of special antiviral drugs. In the early stage, intravenous ribavirin antiviral treatment can be administered, while balanced salt solution and glucose solution can be infused to prevent or treat shock. Plague, on the other hand, requires intramuscular injection of streptomycin, chloramphenicol and other antibacterial drugs for treatment, and fluoroquinolones, third-generation cephalosporins and tetracyclines are also available for treatment. At the same time both for high fever can take physical cooling, and with ibuprofen, acetaminophen and other antipyretic and analgesic treatment. In addition, it is recommended that field workers be vaccinated against hemorrhagic fever and plague, which can effectively prevent the occurrence of the disease, and should ensure daily personal and food hygiene, and do a good job of rodent prevention and extermination. If you are inadvertently bitten by rodents, you should actively clean the wound, go to the epidemic prevention department and take preventive measures according to medical advice.
