Many-times exogenous infections are transmitted from one person to other person or from animals to man.They may occur through the healthcare workers, contaminated device, surface. There are two ways to close the wound, immediate primary closure and delayed primary closure. 2nd approach i.e. delayed primary closure of wounds is preferred for lacerations which are not clean enough to be closed (Craft, 2015).
