There is a wild mice that usually enters the house from somewhere and gnaws the skin from foot. It usually gnaws when we are sleeping. It is not a pet rat. It's a wild one. Is there any disease that can be caused by this?

Yes. There are a number of diseases that can be transmitted by rodents, and several of them can be quite serious. This is the list of diseases that can be directly transmitted by rodents according to the CDC:

  • Hantavirus Pulmonary Syndrome
  • Hemorrhagic Fever with Renal Syndrome
  • Lassa Fever
  • Leptospirosis
  • Lymphocytic Chorio-meningitis (LCM)
  • Omsk Hemorrhagic Fever
  • Plague
  • Rat-Bite Fever
  • Salmonellosis
  • South American Arenaviruses (Argentine hemorrhagic fever, Bolivian hemorrhagic fever, Sabiá-associated hemorrhagic fever, Venezuelan
    hemorrhagic fever)
  • Tularemia

This is not to say that any given rat or mouse might transmit any of these. Other factors come into play, such as which diseases are endemic to the area and which diseases infect which species. On the link above you can expand each disease to see which rodents can transmit it. Unfortunately, rats and mice are included in most of those diseases.

    Is it a coincidence to see so many different hemorrhagic fevers listed here? Oct 26, 2015 at 22:18
  • It only gnawed the skin. There was no bleeding. Can these disease be transmitted through this.

  • @AbhishekAgrawal Yes. Merely being in close proximity to the rodents is sufficient for some diseases. They can be transmitted by urine and feces, and the dust that occurs when feces dry up.

  • @CountIblis It is interesting how many hemorrhagic diseases are listed. Maybe that's the rat's revenge for warfarin.
