Australian Paediatric Surveillance Unit Annual Report, 2016

Abstract

This report summarises the cases reported to the Australian Paediatric Surveillance Unit (APSU) of rare infectious diseases or rare complications of more common infectious diseases in children. During the calendar year 2016, there were approximately 1500 paediatricians reporting to the APSU and the monthly report card return rate was 90%. APSU continued to provide unique national data on the perinatal exposure to HIV, congenital rubella, congenital cytomegalovirus, neonatal and infant herpes simplex virus, and congenital and neonatal varicella. APSU contributed 10 unique cases of Acute Flaccid Paralysis (a surrogate for polio) – these data are combined with cases ascertained through other surveillance systems including the Paediatric Active Disease Surveillance (PAEDS) to meet the World Health Organisation surveillance target. There was a decline in the number of cases of juvenile onset Recurrent Respiratory Papillomatosis which is likely to be associated with the introduction of the National HPV Vaccination Program. The number of cases of severe complications of influenza was significantly less in 2016 (N=32) than in 2015 (N=84) and for the first time in the last nine years no deaths due to severe influenza were reported to the APSU. In June 2016 surveillance for microcephaly commenced to assist with the detection of potential cases of congenital Zika virus infection and during that time there were 21 confirmed cases – none had a relevant history to suspect congenital Zika virus infection, however, these cases are being followed up to determine the cause of microcephaly.
