Earth 7 Flashcards
What are vectors?
Vectors are living organisms, such as mosquitoes and ticks, that transmit infectious pathogens between humans or from animals to humans. Once infected, vectors can transmit the pathogen with every subsequent bite.
What are some examples of vector-borne diseases?
Examples include malaria, dengue fever, Zika virus, yellow fever, schistosomiasis, and Chagas disease.
How does climate change impact the distribution of vector-borne diseases?
Climate change affects vector survival, reproduction, habitat range, and biting rates. Warmer temperatures allow vectors to expand into new regions, increasing the risk of disease transmission.
Why are tropical and subtropical regions more affected by vector-borne diseases?
These regions have climates that favor vector survival and activity. They are often economically disadvantaged, making it harder to combat outbreaks.
What are the socioeconomic impacts of vector-borne diseases?
These diseases cause significant health and economic challenges, including chronic illness, disability, reduced agricultural productivity, and disruptions to ecosystems.
How does climate change influence migration?
Rising sea levels, extreme weather events, and reduced agricultural productivity force people to leave their homes in search of safer and more stable environments.
What are some health impacts of climate change identified by the World Health Organization (WHO)?
Climate change increases the risk of heat-related illnesses, respiratory issues from worsening air quality, waterborne diseases, and malnutrition due to reduced food security.
Why are tropical diseases spreading to Europe and other regions?
Rising global temperatures create suitable conditions for vectors like mosquitoes to thrive in regions previously too cold for their survival, such as parts of Europe.
What factors, besides climate change, influence the spread of vector-borne diseases?
Factors include global travel, trade, urbanization, habitat destruction, land use changes, pesticide application, and host population density.
How can climate change impact mental health?
Extreme weather events and displacement due to climate change can lead to stress, anxiety, depression, and other mental health challenges.
What measures can be taken to reduce the impact of climate change on health?
Measures include strengthening healthcare systems, improving disease surveillance, implementing early warning systems, reducing greenhouse gas emissions, and increasing public awareness.
