The most common disease faced in Alaska during the Klondike gold rush was typhoid fever.
Typhoid fever was the most common afliction that affected miners. This was partly due to the miners building their cabins and tents far too close to each other, on soil that was frequently a flat tundra.
Also, the frozen ground did not allow for surface water to drain off. However the disease would have been far worse had not so many miners constantly boiled their drinking water.
The miners also contracted diseases such as tuberculosis and pneumonia due to the poor conditions of the miner's cabins.
