Studies on health networks have mostly been conducted on groups which typically suffer the most from extreme forms of diseases, for example cancer patients, HIV patients, or patients with other life-threatening diseases. It is general knowledge that one participates in online communities to interact with society and develop relationships. Individuals who suffer from rare or severe illnesses are unable to meet physically because of distance or because it could be a risk to their health to leave a secure environment. Thus, they have turned to the internet. A study conducted by Haven B. Battles and Lori S. Wiener on the effects of networks on children suffering from incurable diseases reveal a positive correlation in enhancing children's behaviors and overall moods. Their behavior and mood not only changed, but they were more willing to go to treatment after having these interactions.
