Questions to Answer
• What are the symptoms of malaria?
• Where is malaria most prevalent?
• How are malaria cases distributed?
• Why does malaria prevail in specific areas?
Symptoms
• If infected one might suffer from:o Fevers, cough, chills, fatigue, sweats, enlarged
spleen, joint pain, diarrhea, headache, loss of appetite, vomiting
• May:o Appear anywhere from 7-30 days after
infectiono Be cyclical, appearing at a variety of intensities
and lengths of time• If left untreated, can cause:
o Impaired function of brain or spinal cord, severe anemia, seizures, coma, death
More About Malaria
• Over 2.5 million die globally every year
• Approx. 40% of world's population live in malaria prevalent areas
• Disease favors:o warm and humid
climateo stagnant pools of
water (near forests)o tropical
environment

Angola
• Population in 2000 was 10,143,267o 21% of
population infected
• Population in 2008 was 12,531,357 o 27% of
population infected
- GNI = $86.9 billion- Climate: semiarid and cool, dry season and hot, wet season- Terrain: plains, plateau
Brazil
• Population in 2000 was 172,860,370
• Population in 2008 was 196,342,592 o 0.16% of
population infected
- GNI = $1.93 trillion- Climate: tropical, in some parts temperate- Terrain: flat lowlands, plains, some hills
Malawi
• In 2000 population was 10,385,849o 35% of
population infected
• Population in 2008 was 13,931,831 o 36% of
population infected
- GNI= $12.1 billion- Climate: sub-tropical, rainy season and dry season- Terrain: plateau, plains, hills, some mountains
Mozambique
• Population in 2000 was 19,104,696
• Population in 2008 was 21,284,701 o 23% of
population infected
- GNI = $17.2 billion- Climate: tropical to subtropical- Terrain: lowlands, high plateaus, mountains
Uganda
• Population in 2000 was 23,317,560 o 15% of
population infected
• Population in 2008 was 31,367,972 o 35% of
population infected
- GNI = $36.1 billion - Climate: tropical, rainy with two dry seasons- Terrain: plateau with rim of mountains
Common Traits
• All have GNI under $90 billion (except Brazil)
• Mainly tropical and dry• Mainly flat, lowlands
- Compared to United States:
• GNI = $14.7 trillion• Climate: temperate• Terrain: plains, mountains, hills
Causes of Prevalence
• Migrationo Refugees, tourists, and migrants aid spread
diseaseo Lack immunity
• Locationo Houses near forest fringeo Houses near water sourceso Rural settlements
Land clearance activities = contact between people and vectors
• Resistanceo Adapt to be resistant to treatments
Causes of Prevalence
• Povertyo Poor quality of housing
Roof and walls o Health Services not accessible o Lack of adequate education
Unaware of symptoms o Non-developed communities
Lack drain systems Lack impervious surfaces
o Unaffordable means of protection Drugs (chloroquine) Insecticides (DDT)
o Poor sanitationo Outdoor labor

Although
• Malaria may be nearly non-existent in an area but...o Being located to migratory groupso Having high tourist rateo Increasing povertyo Lack of adequate sanitation
may resurface high prevalence of malaria
Climate Effects on Malaria
• Rainfall and temperature = important factors for malaria transmission
• Typically, survival decreases as temperature rises and increases as humidity increases
• Rainfall provides setting for aquatic life cycle o Moderate rain can aid spreado Excessive rain can prevent spread
• Temperature is a managing factor o Survive best between 68-77° Fo Intense high temperatures increases mortality
• Studies show possible influence of anthropogenic climate change to distribution of malaria and effects on life cycle of parasite
