Rats may carry different diseases and parasites. Rats have been found to carry both non-zoonotic and zoonotic parasites.
Rodent diseases can infect humans through rodent excretes like saliva, feces and urine or by humans inhaling or handling the microorganism particles from the materials, woodpiles and hay where rats were. They can also be transmitted through bites and scratches.
Salmonellosis can affect pets and humans. The infection may take place through consuming water or food that has been contaminated by the feces of rats.
