How does climate change affect infectious diseases?
The warmer, wetter and more variable conditions brought by climate change are therefore making it easier to transmit diseases such as malaria, dengue fever, chikungunya, yellow fever, Zika virus, West Nile virus and Lyme disease in many parts of the world.
What diseases can you get from climate change?
Impact of warmer and wetter climatesMosquito-borne diseases are probably the greatest threat to humans as they include malaria, elephantiasis, Rift Valley fever, yellow fever, and dengue fever. Studies are showing higher prevalence of these diseases in areas that have experienced extreme flooding and drought.
How will climate change affect diseases?
Climate change will also affect infectious disease occurrence.” A number of diseases well known to be climate-sensitive, such as malaria, dengue fever, West Nile virus, cholera and Lyme disease, are expected to worsen as climate change results in higher temperatures and more extreme weather events.
Why are infectious diseases on the rise?
Emerging infectious diseases are infections that have recently appeared within a population or those whose incidence or geographic range is rapidly increasing or threatens to increase in the near future. Emerging infections can be caused by: Known agents that have spread to new geographic locations or new populations.
What can individuals do to reduce climate change?
Home energy, landscaping and consumption. Reducing home energy use through measures such as insulation, better energy efficiency of appliances, cool roofs, heat reflective paints, lowering water heater temperature, and improving heating and cooling efficiency can significantly reduce an individual’s carbon footprint.
How are infectious diseases?
Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies. They’re normally harmless or even helpful. And you may get others by consuming contaminated food or water or being exposed to organisms in the environment.
How will climate change affect agriculture?
Climate change can disrupt food availability, reduce access to food, and affect food quality. For example, projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity.
How does climate change affect the food supply?
Climate change effects on human water demand and irrigation may intensify these effects. 2 concentrations will reduce the land’s ability to supply adequate livestock feed, while increased heat, disease, and weather extremes will likely reduce livestock productivity.
How does climate change affect plants and animals?
Climate change also alters the life cycles of plants and animals. For example, as temperatures get warmer, many plants are starting to grow and bloom earlier in the spring and survive longer into the fall. Some animals are waking from hibernation sooner or migrating at different times, too.
