"What Exactly is Hemorrhagic Fever?"

Although this disease is not commonly heard or seen in modern times, it was once a highly fatal illness. It is primarily an acute viral infectious disease transmitted from rats infected with the virus to humans. Infection with this hemorrhagic fever virus can lead to symptoms such as fever and kidney damage, with a high incidence rate, critical condition, and a wide range of occurrence, making it a relatively terrifying disease at that time. There are many sources of infection for hemorrhagic fever, but the main one is rodents. Humans who come into contact with anything or feces from infected rodents or other diseased organisms are highly likely to contract the disease. Moreover, this disease can also spread among humans, infecting healthy individuals with hemorrhagic fever. Epidemic hemorrhagic fever, also known as hemorrhagic fever with renal syndrome (HFRS), is a natural focal disease caused by the epidemic hemorrhagic fever virus. It is widely prevalent, critical in severity, has a high mortality rate, and poses significant harm. There are 13 types of human viral hemorrhagic fevers worldwide, which are classified into two categories based on the presence or absence of kidney damage. In China, the primary type is HFRS. Before the pathogen was identified, it was called epidemic hemorrhagic fever (EHF) in China, Korean hemorrhagic fever (KHF) in North Korea, and hemorrhagic nephritis and nephrosis (HNN) in Russia. Due to the establishment of specific serological diagnosis and the resolution of etiology, the World Health Organization unified the name as HFRS in 1982. Currently, China still uses the term epidemic hemorrhagic fever. This disease is a natural focal disease caused by a virus with rodents as the main source of infection. It is an acute viral infectious disease characterized by fever, bleeding tendency, and kidney damage. This disease is mainly distributed in Eurasia, but the spread of HFRS virus has reached almost every continent in the world. In China, it has been prevalent for half a century, with outbreaks occurring in all provinces except Qinghai and Taiwan.

Those who wonder what hemorrhagic fever is should now have a clearer understanding of this illness. In the past, it might have been considered a plague, but thanks to modern health awareness and scientific advancements, people have gained control over this disease. It is recommended to maintain good hygiene and disinfection practices at home to prevent the growth of harmful bacteria and viruses.
