Cellulitis is an acute spreading skin infection that may go deep, involving the subcutaneous tissues.
It typically occurs in areas where the skin integrity has been compromised.
May result from blood-borne spread of infection to the skin and subcutaneous tissues.
It is commonly caused by beta-hemolytic streptococci and Staphylococcus aureus in adults and Haemophilus influenzae type B in patients <3 year of age.
Parenteral antibiotic therapy duration for bacteraemic urinary tract infection (UTI) in young infants may be safely shortened, according to a recent study showing that recurrence and readmission or emergency department revisitation rates are comparable between a ≤7-day and a longer therapy course.
