Contact transmission

Contact transmission is one of the major forms of transmission for many viruses and diseases.It is of two types

1.Direct contact transmission-means when a healthy person directly get in physical contact with the infected person and the disease is transmitted.

2.Indirect contact transmission-means disease causing organism is trasmitted on to any other things or surfaces and later transmitted to any other person who comes in contact or touches the surface.
