The monster known as tuberculosis

Note: In 1905, many farmers had to spend part of the winter working in a logging camp in order to provide for their families. According to the following extract, what were the living conditions in logging camps?

Extract:
“After having visited and studied some of the work sites on the North Shore, we can only state that at least 80% of the camps in the area that interests us are extremely dirty, with little or no ventilation and floors covered in a thick layer of grime. This is where each winter that monster known as tuberculosis will rear its ugly head.”
