What is invatago and treatment and contageesness towards other people?
Invatago is not a recognized medical term or condition, so it's possible you meant "invaginate," which refers to a process where a part of a structure folds inward. If you meant "invagination" in a medical context, such as intussusception, it's a serious condition where a part of the intestine folds into itself, requiring immediate treatment, often surgical. This condition is not contagious; it results from structural issues within the body rather than an infectious agent. If you meant something else, please clarify for a more accurate response.
