Human rabies: modes of transmission
Summary
Rabies transmission is not limited to animal bites. Recent findings show human-to-human spread through corneal transplants and airborne routes, highlighting infection risks for healthcare workers and patient attendants.
Area of Science:
- Veterinary Medicine
- Infectious Diseases
- Public Health
Background:
- Rabies virus is traditionally transmitted through bites or saliva of infected animals.
- Emerging evidence indicates non-bite transmission routes are significant.
- Understanding these novel transmission pathways is crucial for public health.
Purpose of the Study:
- To review and highlight non-traditional rabies virus transmission routes.
- To emphasize the risks associated with airborne and transplant-related infections.
- To underscore the need for updated protective measures.
Main Methods:
- Literature review of documented rabies transmission cases.
- Analysis of epidemiological data on rabies spread.
- Synthesis of information on airborne and iatrogenic rabies.
Main Results:
- Human-to-human rabies transmission via corneal transplantation is recognized.
- Airborne rabies virus transmission documented in laboratory and cave settings.
- Potential risk identified for healthcare workers and attendants of rabies patients.
Conclusions:
- Rabies prevention strategies must evolve beyond bite avoidance.
- Enhanced biosafety protocols are necessary in research and clinical settings.
- Increased awareness and protective measures are vital to prevent novel transmission routes of rabies.
