In simple linear regression a single independent variable is used to predict the value of a dependent variable. In multiple linear regression two or more independent variables are used to predict the value of a dependent variable. The difference between the two is the number of independent variables.
Watching for Systemic Symptoms. 1  1. Watch from swollen glands. Serious cases of cellulitis will spread beyond the initially infected region to become systemic and impact the rest of the body. 2  2. Notice if you experience fever and/or chills.
Cellulitis after an injury from a saltwater fish or shellfish - like a fish bite or a crab pinch - can be due to the Erysipelothrix rhusiopathiae bacteria. These same bacteria can also cause cellulitis after a skin injury on a farm, especially if working with pigs or poultry. Is cellulitis contagious? Cellulitis is not contagious because it is an infection of the skin's deeper layers, the dermis and subcutaneous tissue. The skin's top layer (the epidermis) provides a cover over the infection.
