WHEN & WHERE
BANGLADESH SOUTH EAST ASIA 2007
Banglasdesh Background
LIDC
13% in poverty
Mixed Economy (agriculture, manufacturing, services)
WHAT GEOGRAPHICAL AREA AFFECTED
Significant proportion of country - 60%
252 villages in 40 districts
eg Feni, Dhaka
Diahorreal Disease
Infectious & contagious
Parasites, bacteria & viruses Eg Cholera, e-coli, rotovirus
Contagious (spread person to person eg contact due to overcrowding)
Spread via food & water (contamination by fecal matter)
Disrupted healthcare
PHYSICAL FACTORS AFFECTING SPREAD OF DISEASE
Geography - low lying deltaic, extensive rivers
Poor drainage–> vulnerable to flooding
Extensive area flooded - 50% flooded area
Environmental Factors affecting Spread of disease
Climate
The monsoon rains & cyclones –>
Increase in water temp
Increase in precipitation (frequency & severity)
Persisitent humidity
Perfect conditions for diorreal disease
Sanitation
Infrastructure damaged by floods
–> open sewers
–> poor hygiene conditions
Water Supply
Floodwater contaminated drinking water sources
Increased risk of Diahorreal Cholera & dystentry
Food
Flodwater contaminated crops &livestock
Increase in foodborne illnesses.
Disrupted foodchains–> malnutrition.
Human Factors Affecting Spread of Disease
Socio economic factors eg Inequality, poverty, education levels
Response
Limited access to cholorination kits–> limited resources
Immunisation Programmes
Disrupted immunisation programmes–> vulnerable
population
Health Infrastructure
Floods Damaged hospitals & clinics hindered provision of care & treatment–> further spread
Impacts of Disease on Population
Increased Morbidity (death)
Critical health issue
Up t 100,000 infected within weeks
Strain on Infrastructure
Hospitals overwhelmed
Economic Impact
Negative financial impact - individuals & families - treatment expensive & productivity decreases
Disruption to Daily Life
School & work life, healthcare disrupted
Social Impacts
Orphaned children requiring care
Long term health conditions eg cognitive imoariment & kidney issues.
Lost education time
NATIONAL Strategies used to Minimise Impacts
Emergency relief
Water purification & distribution
Hygiene promotion & education
Healthcare infrastructure investment
INTERNATIONAL STRATEGIES to minimise imoacts
Humanitatrian Aid (WHO & UNICEF)
Provided financial support & technical assistance
Eg Interventions to imrove access to clean drinking water , improved sanitation facilities. vaccinations
Collaboration & capacity Building
Train workers & community groups - hygiene strategies
Research & Surveillance
Monitored outbreaks & guided interventions
WASH study - WHO & 14 research institution to better understand diorrheal disease.
ENVIRONMENTAL FACTORS
Flooding -> stagnation & lack of safe water
Floodwater, increased humidity, food shortages & contaminated water supply & land use changes - perfect for vector & water borne diseases
High population density -
one of highest in world 1200 people/km2
fascilitated rapid spread of disease
especially amongst displaced population
Displacement - camps - overcrowding & poor hygiene
HUMAN FACTORS
Socio economic factors eg Inequality, poverty, education levels
Response & preparedness
International Aid
