How do you know if a burn is serious?
Infection will usually not be seen until at least three to four days after a burn injury. The wound could be infected if there is expanding redness around the wound (some redness on the edges of the wound is normal), yellow or green drainage, or if you develop a fever unrelated to other illness.
Is an infected burn yellow?
As a wound continues to heal, the red tissue will transition to a lighter pink color, which is a very good sign for your wound's progression. This pink tissue under and around a scab is known as epithelial tissue.
