title: [Influenza and pregnancy].
abstract: Influenza is a respiratory disease caused by influenza viruses. The virus is responsible for pandemics by emergence of new viral strains, then for seasonal flu by antigenic drift. Seasonal flu is more frequent and severe in pregnant women, with increased risk of pneumonia and increased risk of hospitalization (but no increased death reported). Pandemic flu is more severe in pregnant women, with increased risk of pneumonia and increased mortality. Influenza vaccination is recommended for all women who are or will be pregnant (in any trimester) during influenza season. After closed contact with a flu case or in case of symptoms compatible with flu, early oseltamivir-based treatment (prophylactic in the first situation, curative in the latter one) is recommended, at any term of pregnancy. The occurrence of flu symptoms in a pregnant woman requires medical evaluation to confirm the diagnosis or identify any alternative infection requiring appropriate therapy like listeriosis, chorioamniotitis, pyelonephritis or viral primo-infection.
