Ah, a virus has a simple structure—genetic material wrapped in a protein coat. It replicates by hijacking a host cell's machinery to make more copies of itself until the cell bursts. But watching this young boy with fever, I don't see structures, only a tired mother's face. My textbooks feel far away from the reality of paracetamol and waiting; the real replication I understand is her worry, multiplying in the quiet ward.
