Health problems in an ELDC
The quality of people’s health is a developmental indicator
If many people are suffering ill health then
this indicates a low level of development.
DEVELOPMENT & HEALTH
It is also a CAUSE of low levels of development
VICIOUS CYCLE OF DISEASE
poverty
Person becomes weak
Little food to eat illness
Unable to work
Causes of ill-health
DEVELOPMENT & HEALTH
Infectious diseases
non-infectious diseases
Spread by watercholeratyphoid
Spread by fliesmalaria
Sleeping sickness
otherAIDs
measles
Diet-deficiencyUnder-nutrition
scurvy
They spread in two main ways:1. people drink polluted water.2. Tiny worms that burrow into the skin when people wash
Flies and mosquitos spread diseases by biting people and
transferring contaminated blood
AIDs is the biggest killer in sub-Saharan Africa.
People not eating enough food. Common in poor areas that have suffered from drought.
Common in MEDC and LEDC.
INFECTIOUS DISEASES•Spread by water
DEVELOPMENT & HEALTH
WATER-BASED DISEASES
These are spread by parasites living in the water and infecting an intermediary host/vector that gives us a disease. They can include;-
The freshwater snail infected by a fluke that infects people and carries SCHISTOSOMIASIS.
INFECTIOUS DISEASES•Spread by flies
DEVELOPMENT & HEALTH
WATER- RELATED DISEASES
These are where the organism which causes the disease lives in water for at least part of its life-cycle.
It can include the mosquito that breeds in water and causes MALARIA.
Other INFECTIOUS DISEASESDEVELOPMENT & HEALTH
AIDSThere is a virus that can be shared through the transfer of bodily fluids. It is called HIV, and destroys part of your immune defence system. If you catch it, there is a chance it will develop into full-blown AIDS, and then even an infection like tuberculosis or another virus like measles can kill you.
It is caught often by needle-sharing drug users, through un-screened blood products being given in clinics, or by having unprotected sex with a victim.
NON-INFECTIOUS DISEASES• Diet deficiency
DEVELOPMENT & HEALTH
A significant proportion of the population are unhealthy and unable to work for any length of time.
They are susceptible to other simple diseases and soon the whole economy suffers.
Malnutrition often happens when diets are based on only one main food source and lacks variety supplied by nutritious
foods.
Areas typical of this are the Indian sub-continent and South-east Asia.
Other NON-INFECTIOUS DISEASESDEVELOPMENT & HEALTH
Diabetes is where the body cannot deal with the sugars in your food that should be stored to release energy when needed. You can go into a diabetic shock if the balance is badly wrong.
Cancers are where the cells of the body keep dividing and won’t stop, as they should. A tumour grows and feeds off your blood supply, eventually killing you. Bits of the tumour can break off and travel to other parts of the body to grow there.
How can you control these diseases?DEVELOPMENT & HEALTH
Produce more food
Improve health facilities
Provide clean water
Provide health education
malariacholera
AIDs
Increases infant mortality
Makes people weak & lethargic
Leaves victims with handicap
People are needed as carers
