AngelKrish get some bleach mix it with water. About 10 parts water to 1 part bleach put it in a spray bottle and spray everything that enters your house. Use it on any cooking surfaces and tables, even door handles every time you use them.
For your hands prepare a solution of water and rubbing alcohol so that it's at least 55% rubbing alcohol. Wash your hands frequently. Yet when done washing use that rubbing alcohol solution.
This might dry your hands out. So use hand lotion. Or at least a light oil.
If you don't have masks use scarves like bandanas to cover your mouth and nose. Wash or even just boil them in water every day.
Keep on minimizing contact with anyone as best as you can.
