Quantifying Global Drivers of Zoonotic Bat Viruses: A Process-Based Perspective.
The American Naturalist
|January 26, 2016
Summary
Emerging infectious diseases (EIDs) are a global threat. This study models zoonotic transmission, identifying drivers of pathogen richness and human contact, crucial for targeted surveillance and intervention strategies.
Area of Science:
- Global Health
- Epidemiology
- Disease Ecology
Background:
- Emerging infectious diseases (EIDs), especially zoonoses, pose significant global health risks.
- Anthropogenic activities are primary drivers of disease emergence.
- Existing frameworks lack empirical modeling of specific emergence steps.
Purpose of the Study:
- To develop a process-based framework for modeling early steps of zoonotic emergence.
- To empirically model drivers of pathogen richness and transmission opportunity.
- To identify high-priority areas for pathogen surveillance and public health intervention.
Main Methods:
- Developed a process-based framework separating components of zoonotic transmission.
- Created a spatial empirical model focusing on bat viruses shared with humans.
- Analyzed drivers including host diversity, climate, human population density, bushmeat hunting, and livestock production.
Main Results:
- Host diversity and climatic variability drive viral richness.
- Human population density, bushmeat hunting, and livestock production drive transmission opportunity.
- Spatial patterns of pathogen discovery and public health intervention may differ.
Conclusions:
- Understanding the processes underlying zoonotic emergence is critical for effective EID control.
- Distinct spatial priorities exist for pathogen discovery versus public health interventions.
- This framework advances empirical modeling of zoonotic EID emergence.

25.6K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

00:36Viral Mutations
40.7K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
