What Does High-Consequence Pathogens Mean?
The January 2018 issue of Emerging Infectious Diseases features high-consequence pathogens. A pathogen is a biological organism that causes disease or illness in its host. But if any pathogen can cause disease, which in itself is a negative consequence, why are only some pathogens considered to be of “high consequence”?
High-consequence pathogens have one or more of the following features:
• potential to cause epidemics or pandemics
• infect/affect many people
• spread rapidly in a short time
• infection results in high cost to society (loss of worker productivity)
• infection results in high cost to the healthcare system
What Are Some Diseases Caused by High-Consequence Pathogens?
High-consequence pathogens include viruses, bacteria, and prions. Here are examples of diseases caused by high-consequence pathogens.
| Viral | Bacterial | Prion |
|---|---|---|
| Poxvirus infections Ebola virus disease Rabies Hantavirus pulmonary syndrome Marburg hemorrhagic fever Rift Valley fever Smallpox* Zika | Actinomycoses & nocardiosis Anthrax Brucellosis Buruli ulcer Glanders Leprosy (Hansen disease) Leptospirosis Melioidosis | Bovine spongiform encephalopathy (mad cow disease) Chronic wasting disease Creutzfeldt-Jakob disease (classic and variant) |
What Is Being Done with Regard to High-Consequence Pathogens?
Scientists are working to protect the public from these pathogens by
• investigating and monitoring outbreaks
• identifying new pathogens and diseases
• seeking better ways to prevent (e.g., vaccines, behavior), diagnose (e.g., laboratory tests), and treat (e.g., medications) those diseases
• developing emergency response plans (for potential or actual outbreaks)
