Social isolation refers to a sense of disconnection and lack of interactions with others in the community [2]. Many people use the terms social isolation and loneliness interchangeably, but they are slightly different. Basically social isolation is the objective state of having fewer contacts or networks in your  community. On the other hand, loneliness is a subjective and negative emotional experience that comes when we realize that we have fewer connections [3]. Yet, they are so close to each other that most literature and policy use these terms together.
