How many people died from beriberi in world war 2?

During World War II, beriberi, a disease caused by thiamine (vitamin B1) deficiency, led to significant mortality, especially among prisoners of war and those in occupied territories. Estimates suggest that tens of thousands of individuals died from beriberi during the war, particularly in the Pacific theater where food shortages and poor nutrition were prevalent. The exact number is difficult to determine due to incomplete records and the chaotic conditions of war.
