Rickettsia conorii subsp. israelensis infection in a pediatric patient presenting skin rash and abdominal pain: a case report from Southeast Iran.

ABSTRACT

BACKGROUND: The healthcare system in Iran appears to overlook Mediterranean spotted fever (MSF) as an endemic disease, particularly in pediatric cases, indicating the need for greater attention and awareness. CASE PRESENTATION A six-year-old patient with fever, abdominal pain, headache, skin rashes, diarrhea, vomiting, and black eschar (tache noire) from southeast Iran was identified as a rickettsiosis caused by Rickettsia conorii subsp. israelensis through clinical and laboratory assessments, including IFA and real-time PCR. The patient was successfully treated with doxycycline. CONCLUSIONS: Symptoms like rash, edema, eschar, and abdominal pain may indicate the possibility of MSF during the assessment of acute febrile illness, IFA and real-time PCR are the primary diagnostic methods for this disease.
