Infectious Diseases In A Warming World


A reading that explains the role of climate change in the spread of infectious diseases. This reading by the World Health Organization describes the various modes of transmission of viral diseases in humans, in animals, and between animals and humans. It further contains examples of how environmental changes have affected the occurrence of various infectious diseases in humans in the past.

Students will learn about the different ways infectious diseases are transmitted and the association of infectious diseases with climatic conditions. They will also briefly understand how predictive modelling has shown that climate change could potentially result in changes in transmission patterns.

Use this tool to help your students find answers to:

  1. What is the zoonotic transmission of a disease? Give examples.
  2. Discuss what zoonotic transmission is, in the context of the SARS-CoV-2.
  3. Discuss process-based (mathematical) models and their use in tracking the spread of malaria.
