How bad was the spread of typhus during 1940s?

Typhus was a major problem during the 1940s, particularly in Europe and Asia, where it caused widespread death and illness. The disease was spread by lice, which thrived in the crowded and unsanitary conditions that were common during the war.

In Europe, typhus was particularly prevalent in the eastern regions, including Poland, Ukraine, and the Balkans. It is estimated that up to 20 million people were infected with typhus during World War II, and millions of those people died. In some areas, the mortality rate from typhus was as high as 50%.

In Asia, typhus was also a major problem, particularly in China and India. It is estimated that up to 30 million people were infected with typhus in China during the 1940s, and millions of those people died.

The spread of typhus was eventually controlled by the use of insecticides and vaccines, but it remains a serious public health threat in some parts of the world.
