In Strachan's estimate of 2001, British losses in the East African campaign were 3,443 killed in action, 6,558 died of disease and c.
90,000 deaths among African porters.
[49] In 2007, Paice recorded c. 22,000 British casualties in the East African campaign, of whom 11,189 died, 9 percent of the 126,972 troops in the campaign. By 1917, the conscription of c. 1,000,000 Africans as carriers, depopulated many districts and c. 95,000 porters had died, among them 20 percent of the Carrier Corps in East Africa.
[50] Of the porters who died, 45,000 were Kenyans, 13 percent of the male population. The campaign cost the British Empire £70 million, close to the British war budget in 1914.
[51][52] A
Colonial Office official wrote that the East African campaign had not become a scandal only "... because the people who suffered most were the carriers - and after all, who cares about native carriers?"
[53] Belgian casualties of 5,000 were recorded, including 2,620 soldiers killed in action or died of disease. This does not count an additional 15,650 deaths of porters.
[54] Portuguese casualties in Africa were 5,533 soldiers killed, 5,640 troops missing or captured and an unknown but significant number wounded.

In the German colonies, no records of the number of people conscripted or casualties were kept but in
Der Weltkrieg, the German official history, Ludwig Boell (1951) wrote "... of the loss of levies, carriers, and boys (sic) [we could] make no overall count due to the absence of detailed sickness records."
[53] Paice wrote of a 1989 estimate of 350,000 casualties and a death rate of 1-in-7 people. Carriers were rarely paid and food and cattle were requisitioned from civilians; a famine caused by the subsequent food shortage and poor rains in 1917 led to another 300,000 civilian deaths in German East Africa.
