My son had a fever (100F) which subsided in 2 to 3 days. After 4 days, he developed red rashes all over his body. On the doctor advice, we got a CBC test along with IgM and IgG tests, IgM was positive. Within 3 days, the rashes disappeared. The CBC report showed some variations (low PCV, MCV, neutrophils), though platelets were near normal. The doctor advised hydration and close monitoring, mentioning it is a mild infection that can become severe. He has been active and playing normally. After 2 days, repeat CBC showed hemoglobin and PCV were increasing. After another 3 days, hemoglobin was higher, PCV remained high, and IgM was still positive. We are worried about these rising trends, though he remains active. Should we hospitalize him or continue care at home?

Likely viral exanthem or Dengue with atypical features. Positive IgM suggests viral response. Monitor hydration and hematocrit closely. Hospitalize if platelet drops or dehydration occurs.
