What about Malaria?Was uber Malaria?
Only infected female Anopheles mosquitoes have the capacity to transmit the parasites (plasmodium)

Introduction
Geography is Destiny in Medicine?Geographie ist Schicksal in der Medizin?
How?
Why?
Any obvious and simple correlation?
Where?
Reflections of environmental determinism

Geographical Variation of Malaria TransmissionGeographische Variation der Malariaubertragung
Increased prevalence of 5 million (211M – 216M)
90% & 91% of cases and death occurs in Africa (194.4M; 407,000)
Highest burden; Falciparum specie
57.3M cases; 100,700 deaths
Disease of the poor

Childhood MalariaMalaria in der Kindheit
The children and nature movement is fuelledby this fundamental idea: the child in nature isan endangered species, and the health ofchildren and the health of the Earth areinseparable. Richard Louv
>2/3 U5 malaria global death i.e U5 death every 2 mins.
Every one minute, a child die before first birth day in Nigeria from a preventable death

Research ObjectivesForschungs objektiv
How can we develop spatial models with integration ofmalaria risk factors that are instrumental to malariacontrol and prevention strategies?
Spatial pattern of malaria
How about direction of malaria spatial pattern?
Risk maps
Scaling up spatial epidemiology in Nigeria?
