Our second patient was a 29-year-old Caucasian woman who was admitted by our Obstetric team with a five-day history of pyrexia and vomiting. On admission she was 37 weeks' pregnant. She had no medical or surgical history of note. On examination, she had bronchial breathing in the entire left lung and the right mid and lower zones. Her CRP level was raised with a moderately raised white cell count. A chest radiograph at this point revealed dense multi-lobular shadowing and consolidation (Figures 2 and 3 ) and she was started on intravenous antibiotics and zanamivir. Osteltamivir was added at a later date. As in our first patient, she continued to deteriorate and developed severe type 1 respiratory failure requiring her transfer to our intensive care unit and invasive ventilation. In light of her deteriorating clinical condition, her baby was delivered by emergency caesarean section. She suffered no immediate post-operative complications and her child was healthy.
