Click âDisease of the Week,â find rotavirus, and take the quiz to test your knowledge! Rotavirus is a contagious virus that can cause gastroenteritis (inflammation of the stomach and intestines). Symptoms include severe watery diarrhea, often with vomiting, fever, and abdominal pain.
The odor of hydrogen sulfide gas can be detected in water at a very low level. Smell the water coming out of the hot and cold water faucets. Determine which faucets have the odor. The rotten egg smell will often be more noticeable from the hot water because more of the gas is vaporized.
In some instances, the smell only occurs when using hot water. If this is the case, the smell is likely originating from bacteria growing in your hot water heater. This can happen if your hot water heater temperature is too low or if itâs turned off for long periods of time, like when you go on vacation.
