Question

What is the “amplification effect” in disease ecology? Provide two real-world examples of the amplification effect.

Answer 1

Ans -Amplification effect: when diverse host communities cause increased rates of parasite prevalence and transmission for a given parasite, often because of increases in the relative abundance of competent hosts (amplifying hosts). Amplifying hosts: competent hosts with high transmission efficiency for that parasite.

. The terms parasite, pathogen, and infectious disease are often used interchangeably in disease ecology to describe organisms that live in or on and obtain resources from a host, usually to the host's detriment.

Pertussis and Measles: Two Vaccine Preventable Diseases Pertussis and measles are two ubiquitous vaccine-preventable diseases of humans. Both are highly infectious and are transmitted in aerosol droplets following contact between infected and sus- ceptible individuals. Pertussis (also called “whooping cough”) is a respiratory disease caused by Gram-negative bacteria of the species
