As the blood and urine of hemorrhagic fever patients carry the virus in the early stages, although there are individual cases of post contact illness reported, people are not the main source of infection, and human-to-human transmission is extremely rare, so there is no need to be overly concerned. Hemorrhagic fever usually refers to renal syndrome hemorrhagic fever, also known as epidemic hemorrhagic fever, is an acute natural epidemic disease transmitted by rodents, and the mode of transmission mainly includes respiratory transmission, gastrointestinal transmission, contact transmission, vertical transmission, and vector transmission. In a few cases, human-to-human transmission may occur when a normal person comes into contact with blood, urine and other contaminants of an infected person. In addition, pregnant women infected with the hemorrhagic fever virus can also be vertically transmitted leading to fetal infection, but the probability of occurrence is extremely small, and as long as they do a good job of self-protection on a daily basis, they will not normally be infected with hemorrhagic fever. Hemorrhagic fever is mainly due to hantavirus infection, the transmission channels mainly include the following: 1, respiratory transmission: rodents carrying virus excreta, such as urine, feces, saliva, etc. discharged into the atmosphere, can be with the dust and other substances in the relatively confined space to form aerosols, when the human body through the respiratory inhalation will cause hemorrhagic fever; but with the new crown pneumonia and other respiratory infectious diseases are different, infected people will not be transmitted to other people through coughing or Breathing to other people; 2, digestive tract transmission: people ingest food contaminated by the virus, may also be infected with hemorrhagic fever disease through the oral cavity or gastrointestinal mucosa; 3, contact transmission: bitten by rodents, or their own wounds in contact with virus-infected feces or blood, may also cause infection; 4, vertical transmission: pregnant women infected with the hemorrhagic fever virus can also be infected to the fetus through the transmission of the placenta; 5, Vector transmission: i.e., insect-borne transmission, such as the leather mite carrying the virus on rats can be used as a vector between human beings and rats. Although Hantavirus has been isolated from the chigger mite and the beriberi mite in China, its role in transmission needs to be further confirmed. Overall, human-to-human transmission of hemorrhagic fever is rare. Infection can be effectively avoided by practicing good dietary hygiene, washing hands frequently before and after meals, and using clean dishes. In addition, plague-affected areas should actively respond to anti-rodent and anti-rodent activities, strengthen indoor disinfection when there are rats at home, ventilate rooms frequently, do not use your body in direct contact with rodents and their excreta, wear masks and gloves when handling rodent excreta and contaminated items in confined spaces, pay attention to hand washing afterward, and go to the CDC or other institutions for emergency vaccinations against hemorrhagic fevers in a timely manner, if necessary.
