Fun Video: How are Pathogens Spread and Controlled? Video Lecture - Class 8

the first part of this video you should
already know that pathogens are
disease-causing microorganisms so how
are pathogens spread they can spread in
many ways by direct contact by water or
by a different pathogens are spread by
different mechanisms so malaria is
transmitted by mosquitoes whereas
cholera is a waterborne disease HIV is
transmitted through bodily fluids and
athlete's foot is transmitted by direct
contact park and transmission be reduced
or prevented depending upon which
disease you are trying to reduce
transmission for depends upon which
method you need to engage simple hygiene
measures can reduce or prevent the
spread of many diseases including flu
and the common cold make sure you wash
your hands properly keep common surfaces
clean and use a tissue just sneeze into
did you know there is a best way to wash
your hands hands wash thoroughly with
soap have significantly reduced numbers
of bacteria over 350,000 people die
every year from food poisoning
which can be prevented by washing hands
and utensils properly with clean water
and cooking foods to a safe temperature
to kill the bacterial pathogens to
produce or prevent cholera and other
diarrhea or causing
pathogens communities need access to
safe drinking water adequate sanitation
so that dirty water is not exposed and
basic hygiene needs such as washing
hands properly boiling water properly
and keeping surfaces clean
malaria yellow fever both have
mosquitoes as a vector and Lyme disease
uses ticks a vector is an organism that
has an active role in transmitting
pathogens from one host to another to
reduce or prevent infection from vector
borne diseases the vectors need to be
controlled or humans need to protect
themselves against the vectors such as
wearing mosquito repellant and wearing
long sleeve clothing insecticide and
spraying techniques can be used to
reduce the population of the vectors but
this is trickier and more expensive if a
disease is highly contagious such as
rabies people may need to be isolated to
prevent the infection spreading to
others vaccinations are also an option
for preventing and reducing pathogens
vaccinations involve putting a small
amount of inactive or dead pathogens
into the body which stimulates the body
to produce antibodies against a specific
pathogen this enables the body to be
prepared to attack or destroy the
pathogen if they are infected in the
future you can learn more about
vaccinations in our water vaccinations
video so from this video you should know
that pathogens are disease-causing
microorganisms and can be a bacterial
virus fungi or protests they are
transmitted in many different ways and
depending upon their mode of
transmission determines how they can be
controlled
