A gram stain is a way of staining cells to determine what category the bacteria falls into (gram positive or gram negative). This is a very important test used to determine what type of bacteria is causing the problem. Gram positive bacteria are types such as Staphylococcus (Staph infections) and Streptococcus (Strep). Gram negative organisms are ones such as Escherichia Coli (E.Coli) and Salmonella. They have defining characteristics that can help the doctor pin point which bacteria is causing the infection, thus being able to give you the proper antibiotic that will take care of the infection.
Impetigo is caused by Staph and Strep infections making it a Gram Positive Bacteria.
Gram-positive and gram-negative refer to the Gram stain used to prepare slides of bacteria for viewing under a light microscope. Viruses are too small to see under a light microscope and have to be prepared differently for viewing under an electron microscope. So the answer to your question is neither.
Chicken pox is caused by a virus called varicella-zoster. Gram stains are used on bacteria not viruses.

The Gram stain is used for bacteria and not for viruses.
Bacteria stain either gram-positive or gram-negative based on the presence or absence of a cell wall. Viruses do not pick up a gram stain.
