Malaria - and its cousin, yellow fever - had significant implications during the war and the debilitating consequences of the disease were already certain before the Civil War had started in earnest and well before its final history had been written.
Several different species of the Aedes and Haemogogus (S. America only) mosquitoes transmit the yellow fever virus. These mosquitoes are either domestic (i.e. they breed around houses), wild (they breed in the jungle) or semi-domestic types (they display a mixture of habits).Humans can acquire yellow fever from jungle mosquitoes.his favours epidemics of yellow fever. Infection causes a wide spectrum of disease, from mild symptoms to severe illness and death.
