Cellulitis is a bacterial skin infection, it is frequent and potentially serious. Cellulitis appears as a swollen and red area of the skin that feels very hot and soft to touch. It can spread rapidly to other parts of the body. Cellulite, in general, is not contagious.
Other skin infections trigger a reaction by the immune system, cause inflammation and tissue damage and also slow the healing process. Most infections remain confined to a small area, such as a scratch or hair follicle, and usually resolve on their own. Many types of bacteria can infect the skin. Skin infections caused by less common bacteria can be contracted by people admitted to hospitals or residences, as well as those who work in gardening, or simply those who swim in a pond, a lake or in the sea.
