This case report documents a fatal neonatal coxsackievirus B4 infection with confirmed myocardial involvement and viral quantification.
Answers are grounded in this paper and cite their sources.
Supports consideration of coxsackievirus B4 in neonatal myocarditis; extends prior reports with quantitative data but remains hypothesis-generating.
We reported a fatal coxsackievirus B4 infection in a neonate. The CSF WBC was elevated, with polymorphonuclear leukocytes predominating initially and lymphocytes predominating later in the illness. Autopsy findings included inflammation of the heart and liver. Coxsackievirus B4 was isolated from the heart and quantitated as 10(3) 50% tissue culture infectious doses (TCID50) per gram of myocardium.
