Where did typhus originally come from?
Typhus was endemic in Poland and several neighboring countries prior to World War I (1914–1918), but became epidemic during the war. Delousing stations were established for troops on the Western Front during World War I, but the disease ravaged the armies of the Eastern Front, where over 150,000 died in Serbia alone.
When did epidemic typhus occur?
A major epidemic occurred in Ireland between 1816–19, and again in the late 1830s. Another major typhus epidemic occurred during the Great Irish Famine between 1846 and 1849. The Irish typhus spread to England, where it was sometimes called “Irish fever” and was noted for its virulence.
Why was typhus important in history?
It was a truism among 19th-century physicians that, in the words of German epidemiologist August Hirsch, “[t]he history of typhus … is the history of human misery.” Commonly associated at the time with the crowded and unsanitary conditions of jails, ships and hospitals, typhus attacked destitute populations mercilessly
Is typhus a virus?
There are two major types of typhus: endemic (or murine typhus ) and epidemic typhus — bacterial infections cause both. The bacteria are small and very difficult to cultivate. Originally, they were thought to be viruses.
How do you prevent typhus?

Who discovered the cure for typhus?
Weigl spent the next four years in Lemberg focusing his research on developing a vaccine for the spotted fever. He led and directed the Institute for Typhus and Virus Research based in Lemberg. Weigl was able to create a vaccine for the spotted fever however, it did not offer immunity against the disease.
What caused the Cocoliztli epidemic?
The epidemic in 1576 occurred after a drought stretching from Venezuela to Canada. The correlation between drought and the disease has been thought to be that population numbers of the vesper mouse, a carrier of viral hemorrhagic fever, increased during the rains that followed the drought, as conditions improved.
