Carriage among Healthy Children in Portugal, 2015-2019.

is an important cause of mucosal and invasive infections and a common colonizer of the upper respiratory tract. As there are no recent data on carriage in Portugal, we aimed to characterize carriage samples and investigate possible parallelisms with disease isolates. Between 2016-2019, 1524 nasopharyngeal samples were obtained from children (0-6 years) attending day-care.
