Is cellulitus contagious? what is cellulitus?

Infectious: Cellulitis is an infection of the skin and soft tissue which can streak and grow if not treated with antibiotics. It can be spread within oneself but not to other people. It requires treatment. See your physician.

inflamed/infectd ? : Cellulitis is simply an inflammation (itis) of the skin. It can be due to an infectious cause such as bacteria but he basically is when the skin gets red, hot, swollen, and tender. Unless there is an open draining wound, it is very unlikely to be contagious since it is otherwise contained by the skin. It is important to identify the cause since antibiotics do not help with no infection.
