Summary
Hantaviruses cause severe diseases like haemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS) globally. These viruses spread to humans through rodent aerosolized secretions, affecting approximately 200,000 individuals annually, primarily in Eurasia.
Area of Science:
- Virology
- Infectious Diseases
- Public Health
Background:
- Hantaviruses are globally distributed zoonotic viruses.
- Infection leads to severe diseases: HFRS and HPS.
- Transmission occurs via inhalation of infectious aerosols from rodent excreta.
Purpose of the Study:
- To summarize the global impact and transmission of hantaviruses.
- To highlight the significant public health burden of hantavirus infections.
Main Methods:
- Review of epidemiological data on hantavirus infections.
- Analysis of known transmission routes and affected populations.
Main Results:
- Hantaviruses cause HFRS and HPS worldwide.
- Approximately 200,000 cases occur annually, predominantly in Eurasia.
- Rodent-derived aerosols are the primary route of human transmission.
Conclusions:
- Hantavirus infections represent a substantial global health concern.
- Understanding transmission dynamics is crucial for prevention and control strategies.
- Targeted public health interventions are needed, especially in high-incidence regions.
