Fever in an Immunocompromised Child

A fever in an immunocompromised child is a possible invasive infection until assessed. Neutrophils normally help contain bacteria and fungi; when their number or function is reduced, infection can progress before redness, pus, or swelling becomes visible. Chemotherapy may also injure the oral and gastrointestinal mucosa, creating entry points for organisms, while a central line provides direct access to the bloodstream. A child who is smiling, playing, or only mildly febrile can still be seriously ill. The experienced nurse therefore responds to the combination of fever and host risk before searching for a reassuring explanation. The immediate questions are: Is the child physiologically stable? Could the child be neutropenic? Can cultures and empiric treatment be started without delay?
