Questions and Answers

What is the expected impact of rising temperatures on the rate of pathogen development and transmission season duration in endemic areas?

  • Increase in rate of pathogen development and transmission season duration (correct)
  • No impact on rate of pathogen development and transmission season duration
  • Unpredictable impact on rate of pathogen development and transmission season duration
  • Decrease in rate of pathogen development and transmission season duration

How might extreme heat affect the prevalence of dengue and other vector-borne diseases in some areas?

  • Their prevalence will remain unaffected by extreme heat
  • Their prevalence will increase due to better pathogen survival
  • They may become more common due to increased vector activity
  • They may become less common if vector survivability or feeding is compromised (correct)
