Malaria was a parasitic disease caused by Plasmodium infecting the human body, and it was the greatest challenge facing the development of the East African colony.
Daytime temperatures in the East African colony remained around twenty degrees Celsius year-round, while coastal areas often stayed above thirty degrees.
The conditions were exceptionally suitable for mosquitoes, and malaria was transmitted through Anopheles mosquito bites.
Thus, in regions where mosquitoes ran rampant, malaria spread more widely. Especially in this era, people still did not know that malaria was transmitted by mosquitoes.
Unable to cut off malaria's transmission at its source, malaria was widespread from tropical to subtropical regions.
In the early days of developing the East African colony, the immigrants suffered untold hardships. Even under the East African government's mandatory orders, large-scale renovations were carried out to improve sanitation and living conditions.
Yet they achieved little, because East Africa had initially been a vast wilderness covered in luxuriant vegetation. Especially during the rainy season, the weather was hot and humid, and mosquitoes bred at a furious pace.
The immigrants had only just arrived and were few in number, so naturally they could not transform their living environment quickly. Many fell victim, and quite a few were carried off by malaria and other tropical diseases.
Fortunately, the immigrants who had survived in the Far East and crossed the ocean after a long, arduous journey had already weathered every storm imaginable.
Much like the Black slaves sent to the United States through the slave trade, they were the physically strongest among those Africans who had been sifted by both nature and human hands.
The Far Eastern immigrants who reached East Africa alive were much the same. Of course, to ensure the immigrants' survival rate, the conditions aboard their transport ships were far better than those
