Cellulitis is a skin condition where there is inflammation of the deeper layers of the skin such as the subcutaneous fat and dermal layer. While it can affect any part of the body, it usually affects the legs or face. It is caused by a bacterial infection and affects individuals of all ages, race, and gender. Cellulitis is most commonly seen in the elderly and middle age individuals. If untreated, it can spread further and involve the lymph nodes. If the infection reaches your blood stream, it can cause septicemia (or you may know it better as blood infection) leading to a life-threatening situation.

Many cases of cellulitis can be treated on an outpatient basis with no long-lasting effects. However, in some cases, admission may be needed in advanced or severe cases. If you suspect that you or someone you know have cellulitis, it is important to seek medical attention to avoid complications.

Cause #1: Bacteria

The most common bacteria types that cause cellulitis are Streptococcus and Staphylococcus. These strains are responsible for many other conditions such as strep throat, impetigo, folliculitis, abscess, and more. Both these strains are commonly found on humans and do not cause any issue until it manages to invade the deeper layers of the skin or blood stream.

Coming into contact with those who carry the bacteria can increase the risk of infection. Bacterium such as the staphylococcus strain is very hardy and can survive in the harshest environments. It can be found on surfaces such as tables, clothing, and more. Some of the other bacteria that can also cause cellulitis are methicillin resistant staphylococcus aureus (MRSA), haemophilus influenzae, clostridium, and pneumococcus species.
