A father brings his 9-month-old to the pediatrician with concerns about a rash. The infant has been experiencing a fever and cold symptoms for a few days, and the rash appeared last night. It’s worth noting that the baby started daycare two weeks ago. During the examination, the child is alert and responsive with good muscle tone. The baby has no fever, and all vital signs are normal. There is some nasal congestion, and a papular rash is present on the trunk, which disappears when pressed. What is the most probable cause of the rash?
