Influenza infection during pregnancy

Influenza is the acute viral infection of respiratory system which is seen commonly and usually self-limiting. In some specific cases such as pregnancy, the complications of the disease tend to be seen more common compared to the general population. During influenza season, the admission to the hospital, hospitalization requirement and intensive care need due to acute respiratory distress in pregnant women because of influenza infection is significantly higher than the women who are not pregnant. Seasonally, the first cases with influenza infection are reported in October, with an increase in the reports during January and February, and the cases are reported until May. During the period between October and May, known as the influenza season, inactive influenza vaccination is recommended for pregnant women. Inactive influenza vaccination can be done at any period of pregnancy. Although live attenuated influenza vaccines can be used during postpartum period, it should not be used during pregnancy. The diagnosis of influenza infection is usually established clinically. Empiric treatment is recommended for pregnant women in case of clinical suspicion, without waiting for the results of diagnostic tests particularly in pandemic conditions. The pregnant women with hospitalization indication, who are suspected or confirmed for influenza infection, should be hospitalized and appropriate antiretroviral treatment should be initiated as soon as possible without waiting for the results of diagnostic tests. During pregnancy, the use of neuroaminidase inhibitor antiviral medications is indicated for the treatment and prophylaxis after influenza exposure for patients who have suspected or confirmed influenza infection. Oseltamivir is an outstanding neuroaminidase inhibitor to use in the treatment and prophylaxis of influenza infection during pregnancy as the resistance rate of influenza strains is low, its systemic absorption is well and clinical experience regarding this medication is high.
