A scrape can easily become infected as the tissues are open and allow bacteria to enter the body, according to Drugs.com. The bacteria leads to slowed healing and many other symptoms. Depending on the germ that entered the skin, the symptoms can range from mild to moderate and even cause severe complications. Keeping the scrape covered will reduce the chances of infection.
Wound Changes
An infected scrape will ooze fluid, blood or pus, explains Drugs.com. Seattle Children's Hospital points out that the infected scrape may pimple or form a yellow crust over the area. There may be an odd color or bad smell associated with the discharge. Swelling at the site of the scrape that does not go away after five days is another symptoms reported by Drugs.com. Infection may be suspected if the swollen area is red, feels painful or warm to the touch. Other signs to look for, according to the Seattle Children's Hospital, include an increase in scab size, the development of a red streak that spreads from the wound to the heart and/or the scrape has not healed after 10 days.
Other Symptoms
Fever, chills, lowered body temperature, swelling of the lymph node near the scrape, reduced blood pressure or an irregular heartbeat may accompany the infection, states the Seattle Children's Hospital.
Lasting Effects
Drugs.com suggests that the scrape will not heal at a normal rate. They also point out that the wound may bleed easily even after time has passed. Infection should also be suspected if the scrape is painful even after it appears to be healed.
