The Effects of Climate
Change on the Spread of
Infectious Diseases
There are four ways climate affects
infectious disease
Rising sea levels
Humidity
Changes in rainfall amounts
Temperature changes
Many diseases are spread to
humans by tiny insects
Mosquitoes are responsible for many
infections in tropical areas
Ticks spread diseases in drier areas,
usually more up north
Mosquitoes and the spread of
malaria
More than 3,000 children die from
malaria each day
Climate change has an affect on this
disease because mosquitoes are
unable to thrive in extremely high
temperatures
They tend to live longer in areas
where temperatures do not vary
greatly
Ticks and the spread of Lyme
disease
Lyme disease hits closer to home
because it is common in the U.S.
It is a life-threatening disease that can
be treated with antibiotics if caught in
time
Climate affects this because ticks
tend to live longer in hot, humid areas
Natural disasters and their affect on
disease spreading
Severe flooding can lead to
contamination of water
Severe drought can also make clean
drinking water hard to come by
Cholera is a deadly disease that is
spread through water
Diseases common in America that
occur during certain climate
changes
Influenza is a common infection that
is currently prevalent due to the
weather change
Meningitis, a more serious illness
tends to thrive in a dry climate
Alarming facts
Scientists are finding it increasingly
possible that deadly diseases such as
malaria could make it’s way up north
due to the harmful affects of global
warming
The reason for this is because the
disease thrives in warmer weather,
which is become more common in the
north due to global warming
What we can do
Educate ourselves on the harmful
effects global warming has on all of
our lives
Find out what we can do to preserve
energy and keep the earth as healthy
as possible
