This was similar to the 172 cases confirmed in the fourth quarter of 2014. There were 113 cases in the third quarter of 2015. Of the samples which underwent serotyping (n=156), 86% were non-capsulated Haemophilus influenzae (ncHi), a further 13% were serotype a, e, or f, and 1% were serotype b (Hib). This was similar to the fourth quarter of 2014 where: 86% of serotyped samples were ncHi, 13% were serotype a, e, or f and 1% were Hib. Age-group was well reported (see table). Of the laboratory confirmed cases during the fourth quarter of 2015: 86% were aged 15 years and over; 7% were under one year of age, 4% were 1-4 years old, and 3% were among 5-14 year olds. In the fourth quarter of 2014: 81% were aged 15 years and over; 8% were 1-4 years, 7% were under one year, and 2% were 5-14 year olds. During this quarter, 86% of cases in children under 15 years were ncHi (n=18/21). There were no cases of Hib in this age-group during the fourth quarter of 2015. In comparison, there were two cases in unimmunised children during the fourth quarter of 2014.
