Although we are now experiencing the post pandemic phase, the A H1N1 virus has emerged as the predominant virus in the current seasonal influenza season affecting Europe and the UK, with significant morbidity and mortality rates affecting the younger population and pregnant women. Most people who catch swine flu experience mild symptoms and make a full recovery. However, pregnant women are more likely to develop life-threatening complications should they catch the flu. It is important for pregnant women seek medical advice early and are started on antiviral treatment, ideally within 48 h, but they can also be effective up to 7 days. If, in spite of treatment, they do not get better, they must contact their doctor or midwife. It is vitally important to treat any fever in pregnancy with paracetamol and drinking plenty of fluids.
