The wikipedia article you quoted contains more references to typhoid fever:
In November 1941 a typhoid fever epidemic broke out in the Lager-Ost; it lasted until March 1942 and an estimated 45,000 prisoners died and were buried in mass graves. The camp administration did not start any preventive measures until some German soldiers became infected.
Stalag IV-H: Of the 10,677 inmates in the camp before the typhoid fever epidemic in December 1941, only 3,729 were still alive when it ended in April 1942.
Stalag VIII-E: The first Soviets arrived in July 1941; by June 1942 more than 100,000 prisoners were crowded into this camp. As a result of starvation and disease, mainly typhoid fever and tuberculosis, close to half of them died before the end of the war.
Stalag XI-B: In July 1941, over 10,000 Soviet army officers were imprisoned here. Thousands of them died in the winter of 1941/2 as the result of a typhoid fever epidemic.
And then one reference for typhus:
Stalag IV-B: In July about 11,000 Soviet soldiers, and some officers, arrived. By April 1942 only 3,279 remained; the rest had died from malnutrition and a typhus epidemic caused by the deplorable sanitary conditions. Their bodies were buried in mass graves. After April 1942 more Soviet prisoners arrived and died just as rapidly.
The problem is: That is complete bullshit! These wikipedia clowns have no idea what they're talking about. A few of these cases might have been typhoid fever, but most of them died with high probability from typhus.
I told you about the confusion with typhus and typhoid. If you look up "Typhus" in a German medical dictionary, you get the entry for typhoid fever. The German word "Typhus" refers to the disease that is known in English as typhoid fever. And the same problem exists in several languages.
Typhoid epidemics with tens of thousands of victims, and then several of such outbreaks in succession, are basically impossible. These outbreaks can only have been typhus.
According to this wikipedia article tens of thousands of soviet POWs died form several typhoid fever outbreaks, but only a few thousand from one typhus outbreak. That's completely ridiculous.
And that's the reason why I suspect that the parents of the twins you referred to died from typhus and not from typhoid.
But you can never be sure. It could have been typhoid, it's not impossible.
Btw., you wrote:
And now to my mothers side of the family. Her oldest brother Izzi Wasserman(Woziwoda) left Poland around the first World War 1914 or so for America via Germany. Her elder sister Rivka her husband and twin daughters – Hanna and Ita, also went to Russia along with my mother and Ciocia (Auntie) Bella – second older sister. In Minsk the twins parents died of typhoid epidemic in 1943 and the twins were taken to an orphanage.
The "twins parents" means your mother's sister Rivka and her husband? We're talking about your aunt, right?
