Rats can carry and spread infectious diseases. When they roam about, their feces, urine, or saliva contaminate water, food, and even dust. If humans have direct contact with this contaminated water, food, or dust, dangerous diseases such as hantavirus or salmonellosis may be spread to them. These diseases may also be spread through rat bites. Occasionally, some rats can be aggressive. They may attack and bite humans, spreading various dangerous diseases.
