Chloe is a five-week-old infant whose mother, Jenny, brings her to see her GP with a two day history of coryzal symptoms, including rhinorrhoea and occasional cough. A COVID-19 swab performed yesterday was negative. Jenny reports Chloe was unsettled after feeding the previous night.

There are no reported sick contacts, and Chloe’s parents are otherwise well. Chloe is the first child of the family, born at term by normal vaginal delivery. Pre-natal and maternal history are unremarkable.

Chloe’s baby check was reported as normal and she was discharged from hospital on day two. She is solely breastfed and has otherwise been thriving until now.

The GP observes that Chloe is vigorous and alert with no signs of dehydration. She is afebrile. Respiratory rate is 30, heart rate 110bpm and O2 saturation of 95%. There is very mild intercostal recession and occasional scattered wheeze on auscultation. Her examination is otherwise normal.
