Typhus not execution?

https://en.wikipedia.org/wiki/Typhus

"During World War II, many German POWs after the loss at Stalingrad died of typhus. Typhus epidemics killed those confined to POW camps, ghettos, and Nazi concentration camps who were held in unhygienic conditions. Pictures of mass graves including people who died from typhus can be seen in footage shot at Bergen-Belsen concentration camp."

"thousands of prisoners in concentration camps such as Theresienstadt and Bergen-Belsen who died of typhus"
