Introduction
In general, hemorrhagic fever refers to epidemic hemorrhagic fever, which can be transmitted through the respiratory tract, digestive tract, insect bites, direct contact, and vertical transmission. Rodents carrying the virus may contaminate the environment with their excretions such as urine, feces, and saliva. When these contaminants become airborne as aerosols, they can infect humans via the respiratory tract. If a person feels unwell, they should promptly seek medical examination and treatment at a正规 hospital.
Under normal circumstances, hemorrhagic fever refers to epidemic hemorrhagic fever, which can be transmitted through respiratory routes, the digestive tract, insect bites, direct contact, and vertical transmission. The specific mechanisms are as follows:
1. Respiratory Transmission
Viral excretions from infected rodents, such as urine, feces, and saliva, may contaminate dust and form aerosols that can infect humans via the respiratory tract.
2. Digestive Tract Transmission
Consuming food contaminated by virus-carrying rodents may lead to infection through the oral cavity or mucous membranes of the gastrointestinal tract.
3. Insect Bites
Certain insects may carry bacteria or viruses, and individuals bitten by these insects may become infected.
4. Contact Transmission
Infection can also occur through rodent bites or when broken skin or wounds come into contact with viral excretions or blood from infected rodents.
5. Vertical Transmission
If a pregnant woman becomes infected, the virus may cross the placenta and infect the fetus. Hantavirus has been isolated from the organs of fetal tissue obtained from miscarriages in pregnant women with hemorrhagic fever with renal syndrome.
If patients experience discomfort, they should promptly seek medical evaluation and treatment at a正规 hospital to avoid delays in diagnosis and management.
