Typhoid fever is contracted by the ingestion of the bacteria in contaminated food or water, through poor personal hygiene, or close contact with someone who is infected. Patients with acute illness can contaminate the surrounding water supply through stool, which contains a high concentration of the bacteria.
Turn off the main water valve that provides water to the bathtub and open the faucet handle to relieve the pressure. Remove the handle cover cap by prying it off with the blade of a pocket knife. Unscrew and remove the central handle screw, using a Phillips screwdriver. Pull off the handle.
If the bathtub leak is coming from a place other than the faucet, fill the tub up with water and turn off the water. If the leak is somewhere in the tub itself, you will be able to see very quickly where it is coming from. Cracks in the actual tub itself are relatively rare.
