How long does rat poop stay toxic to humans?

Rat poop is dangerous as long as it's present and can transmit diseases like Hantavirus and Salmonella through inhaling dust, touching it, or consuming contaminated food, with viruses potentially surviving days and bacteria weeks in cool, dark conditions, though sunlight and disinfectants kill them.
