Climate Change."
Climate change might allow some infectious diseases
to spread. As winter temperatures increase, ticks and
mosquitoes that carry diseases can survive longer
throughout the year and expand their ranges, putting
more people at risk. One big concern is malaria, a
deadly disease spread by mosquitoes in many hot,
humid parts of the world.
What can people do about it?
People should take common sense steps to avoid tick
and mosquito bites, and communities can take actions
to control mosquitoes, such as removing sources of
standing water. It's also important for doctors to know
the symptoms of diseases that could be spreading to
new areas so they can diagnose and treat their
patients.
