Epidemiology of Haemophilus influenzae in children on Lombok Island, Indonesia

Abstract

The Haemophilus influenzae serotype b (Hib) conjugate vaccine routine immunization programme has been implemented for almost a decade; however, there is limited surveillance of H. influenzae carriage rates in the Indonesian population. H. influenzae was isolated from nasopharyngeal (NP) swab specimens of healthy children on Lombok Island, West Nusa Tenggara Province, Indonesia from 2018 to 2019. Serotyping was performed using quantitative polymerase chain reaction. We identified H. influenzae in 40 of the 96 (41.6 %) NP swab specimens. We identified 39 non-typeable H. influenzae (NTHi) isolates and 1 Hib isolate.
