Amy is 2 years old and is seen with her mother who is concerned about a pink macular rash which has developed on her trunk today. Amy has been complaining of a sore throat and also had a fever for the last 3 days. Her temperature 2 days ago was 39.3°C but has been normal today.
On examination today, she is apyrexial with normal observations. Her throat examination is normal, and a rose-pink macular rash is observed on the trunk and thighs.
Based on her likely diagnosis, which virus is usually implicated?
