Ticks, Mosquitos, and How Climate Change Could Increase Disease

The video discusses the multifaceted effects of climate change on human health, focusing on the increase in vector-borne diseases like malaria and Lyme disease. It explains how climate change affects the distribution and survival of disease vectors and pathogens, leading to more widespread and severe health issues. Deforestation and urbanization further exacerbate these problems by increasing human contact with wildlife and disease vectors. The video also highlights potential solutions, such as regulating deforestation and supporting climate action, to mitigate these impacts.

What is a vector in the context of vector-borne diseases?

• A type of bacteria

• A climate change effect

• An organism that transmits pathogens

• A type of virus

How does climate change affect the geographical range of ticks?

• It expands their range

• It reduces their range

• It makes them extinct

• It has no effect

What is the projected impact of climate change on West Nile virus cases by 2050?

• Cases will decrease

• Cases will triple

• Cases will double

• Cases will remain the same

How does deforestation contribute to the spread of infectious diseases?

• By decreasing the number of vectors

• By disturbing the natural environment of pathogens

• By increasing the natural habitat of vectors

• By reducing human contact with wildlife

What is 'spillover' in the context of infectious diseases?

• When a pathogen is contained within a species

• When a pathogen is eradicated

• When a pathogen jumps from one species to another

• When a pathogen becomes less virulent

How can climate migration affect disease transmission?

• By decreasing human contact with wildlife

• By reducing population density

• By introducing diseases to new areas

• By eliminating disease vectors

What is one strategy to mitigate the effects of climate change on disease spread?

• Increasing deforestation

• Uncontrolled urbanization

• Ignoring climate change

• Regulating deforestation
