What are the 3 components of the epidemiological triad?

Amplification

The term referring to when infectious agents multiply rapidly to high levels

Antimicrobial resistance, travel and trade, live animal markets, urbanization, population growth, an older growing population, climate, landuse/ecosystem changes

Describe the reasons for why we are seeing emerging diseases?

Landuse/Ecosystem changes, climate/weather

What are the top two most important reasons for emerging diseases?

Infectivity, pathogenicity, virulence, immunogenicity, antigenic stability, survival

What are some variables listed under "agent" in the epidemiologic triad?

Species, age, sex, breed, conformation, genotype, nutrition, physiological condition

What are some variables listed under "host" in the epidemiologic triad?

Weather, housing, geography, geology, management, noise, air quality, food, chemical

What are some variables listed under "environment" in the epidemiologic triad?

Zoonotic or vector borne

70% of reemerging or emerging infections are described as ....?

We need to have "spillover" where a disease transmits from wild animals to domestic animals to humans. After spillover occurs to humans, there is "amplification" of disease, where the infectious agent multiplies rapidly within the population

Describe spillover and amplification in communication with each other
