Is hemorrhagic fever plague highly contagious?

Generally, hemorrhagic fever and plague are two distinct zoonotic diseases, both of which are highly infectious. A detailed analysis is as follows:

Although both hemorrhagic fever and plague are zoonotic diseases, they are caused by different pathogens. Hemorrhagic fever is caused by hantavirus, whereas plague results from Yersinia pestis infection. This fundamental difference leads to clear distinctions in their transmission routes and clinical features. In terms of transmission, hemorrhagic fever primarily spreads through contact with rodent excretions or secretions, or via inhalation of virus-containing aerosols into the respiratory tract. Plague, on the other hand, is mainly transmitted through bites from infected fleas carried by rodents; it can also spread through direct contact with tissues of infected animals or via inhalation of respiratory droplets. Clinically, hemorrhagic fever typically presents with fever, bleeding tendencies, and kidney damage. Plague has a more abrupt onset and may lead to severe symptoms such as high fever, swollen and painful lymph nodes, and shock, with a significantly faster disease progression.

Daily prevention should focus on rodent control. Regularly clean clutter in living areas, store food properly with moisture-proof and rodent-proof measures, and avoid direct contact with rodents and their excreta. When going outdoors, practice personal protection by wearing long-sleeved clothing, gloves, and masks. If unexplained high fever, bleeding, or swollen lymph nodes occur, seek immediate medical attention. During transit to medical facilities, maintain self-protection and avoid close contact with others.
