Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Cytomegalovirus (CMV) is a common herpesvirus infection with a wide range of presentations, from no symptoms to fever and fatigue resembling infectious mononucleosis. Step 2: Congenital CMV can cause hepatosplenomegaly, jaundice and a blood picture that mimics erythroblastosis (haemolytic disease of the newborn), which is why CMV is the best fit here. Step 3: Like EBV, CMV can produce an infectious mononucleosis-type illness in adolescents and young adults with fever and fatigue, but EBV additionally causes a severe sore throat whereas CMV does not. Step 4: HSV and Staphylococcus produce quite different clinical pictures (vesicular mucocutaneous disease and pyogenic infection respectively), so the answer is CMV.
