INFECTIOUS DISEASES
MALARIA
spread
economic
limited provision & access to healthcare inaccessible, unavailable, and unaffordable due to great distances, people delay receiving treatment, which allows the disease to spread in the meantime
environmental
-
climate with heavy rains, blocked water drains caused by accumulation of debris are cleared out, and malaria infection decrease temporarily
post-monsoon period results in pools of stagnant water, leading to rises in malaria epidemics
natural disasters malaria incidences increase after disasters ie. water disasters - tsunamis, destructive disasters - earthquakes bursting water pipes
social
lack of proper sanitation inadequate drainage systems and uneven grounds - allow stagnant water which provides favourable breeding grounds for mosquitoes #
-
expansion diffusion tropical and subtropical zones, ideal for . mosquito breeding
impacts
economic
cost of healthcare governments set aside funds for the provision of healthcare to address the infected
loss of productivity in the long-run loss of productivity in the workforce, slow down economic growth
household expenditure on individuals and families, increased medical expenses
social
death rate Democratic Republic of Congo and Nigeria accounted for over 40% of total global malaria deaths in 2010
infant mortality rate 14% of children born in Nigeria die from malaria within their first year of birth
37.5% of infants die from malaria infection during pregnancy within their first year of birth
HIV/AIDS
both expansion and relocation diffusion transmitted from pregnant mother to baby, blood transfusion, sharing of infected needles, and sexual contact
spread
social
education LDCs uneducated on how the disease is transmitted, unable to protect themselves #
cultural practices young girls are and uneducated and unaware of the sexual awareness until marriage
social stigma lack of awareness of how it is transmitted, heavily discriminated against
medical malpractice contaminated containers and syringes, no effective blood screening before transfusions, unaffordable
-
impacts
social
-
orphan crisis children lose their parents to HIV/AIDS, individuals who care for orphans deal with added medical and living expenses, driving them deeper into poverty
orphans themselves faced with inaccessibility to shelter, food, healthcare, and education - discriminated against and may also be infected with HIV/AIDS
economic
cost of healthcare antiretroviral drugs (do not cure but slow down progressions) can be expensive in both DCs and LDCs
individuals drugs have to be taken daily for the rest of their lives, pregnant mothers have to go through screening before birth to reduce the risk of HIV/AIDS being passed down
government allocate limited resources to care for patients, especially if providing subsidies; slows down economic growth and educational development #
loss of productivity long-term economic impact businesses are less likely to invest in places without proper infrastructure, unskilled labour force, and poor health
ENDEMIC: low levels in a particular region ; affected by environmental conditions (for optimum spread, geographical location) eg. insect-borne
EPIDEMIC: sudden, large outbreak which affects a population at higher than normal rates (*rate of spread) eg. cholera
PANDEMIC: widespread, continental/global scale (*geographical scale of spread) eg. malaria
