•
•
•
•
Unsanitary living conditions,
Warfare,
Famine,
Poor or Non-Existent Medical Care,

• Most third world (developing nations)
nations suffer from all of the above causes.
Epidemic and Pandemic
• Epidemic?
– An epidemic may be restricted to one location
– For example the nation of Ethiopia in Africa
• Pandemic?
– is an epidemic of infectious disease that has spread
through human populations across a large region; for
instance multiple continents, or even worldwide
– For example HIV/AIDS is a Pandemic around the
World
UN/International Reaction to Disease
• United Nations: World Health Organization (WHO)
• The World Health Organization (WHO) is a specialized agency
of the United Nations (UN) that is concerned with
international public health
• Its current priorities include communicable diseases, in
particular, HIV/AIDS, malaria and tuberculosis; the mitigation
of the effects of non-communicable diseases; sexual and
reproductive health, development, and ageing; nutrition, food
security and healthy eating; substance abuse; and drive the
development of reporting, publications, and networking.
UN/International Reaction to Disease
• The UN and International community has assisted in
• teaching,
– Water desalination, water purification, food preservation, crop
rotation, sexual education, medical treatment, etc…
• treating,
– Providing Healthcare, preventive care, etc…
• and inoculating people of the third world when possible.
– Inoculating against common diseases,
Bacteria
• A microbe that infects humans
• Can be cured by antibiotics
Virus
• Non living attaching to living cells
and replicates
• Preventable with Vaccines
Types of Bacteria
Anthrax
• A bacteria that usually comes from
infected animals
• Causes black ulcers, swelling, and
can be fatal
Botulism
• Enters in wounds or improperly
canned foods
• Creates poisons that can kill you if
your immune system is weak
Tetanus

• Locks up muscles
• 1 out of 3 die
Leprosy
• Lesions and lose function of body
parts
Cholera
• Infects intestines
• Can get from shellfish
Plague
• Carried by fleas on rodents
Antibiotic Resistance
• Bacteria are evolving and have
become harder to kill with antibiotics
• Race to create the next antibiotic
before it becomes resistant
Outbreak!
HIV/AIDS
• Destroys white blood cells which
prevent disease
• Have origins in monkeys
• Spread by blood
Influenza (THE FLU)
• Normally a Virus that is dangerous for
the old and the young
• Many different types
• Vaccine only designed for some form of
the flu
• Mutated throughout history = Spanish
Flu killed 80 million from 1918-1920
Avian (Bird) Flu
• Virus that birds can come sometimes
pass to humans
• Very deadly
• Fear is that it will mutate and will be
passed between people and become
airborne
Swine Flu
• New mutation sweeping world
• Started in Pigs passed to human
• Human to human contact now
happening
Vaccines
• Give in an injection that gives you a
dead form of the Virus
• Body see the virus and produces
antibodies to fight future infections
• Sometimes viruses mutate making
vaccine useless
VICTORY!!!
SMALL POX
• 33% would die - 5% Blind – 60%
Scared
• December 1979 ERADICATED
• Only disease to be destroyed
