Resumen
Objective The aim of this study was to present results of the postpandemic
phase of A(H1N1)pdm09 virus infection in pregnant
women in Cear a, Brazil, during the January–June 2012 influenza
season.
Results One hundred and fifty-four nasopharyngeal swab samples
were collected from pregnant women admitted to hospitals with
suspected severe acute respiratory infection (SARI). Fifty-three
(34 4%) had laboratory-confirmed A(H1N1)pdm09 virus infection
with 15 (28 3%) outpatients and 38 (71 7%) hospitalized. Five
(9 4%) women were in the first trimester of pregnancy, 20 (37 7%)
in the second trimester of pregnancy, and 24 (45 2%) in the third
trimester of pregnancy. Three had no information about the time of
pregnancy. Six samples from newborns were also analyzed, of which
three were nasopharyngeal swab positive for A(H1N1)pdm09. These
swabs were collected immediately after birth, with the exception of
one that was collected on the day after birth.
Conclusion Our findings suggest that transplacental transfer of
influenza viruses could occur as a result of severe illness in
pregnancy. It is therefore important to encourage women to be
vaccinated against influenza in order to avoid pregnancy
complications.
