In March 2017 I commenced the Master of Applied Epidemiology program, hosted in the Communicable Diseases Branch at Health Protection New South Wales (NSW). Presented in this bound volume are four research projects: an epidemiological study, data analysis study, outbreak response, and an evaluation of a public health surveillance system. I was also heavily involved in routine public health work including on-call, outbreak investigations and follow-up of laboratory notifications. The

The epidemiological study was an audit that estimated true immunisation coverage of NSW children at one year of age on the Australian Immunisation Register (AIR), and explored reasons associated with under-reporting. Our estimate of true coverage was 96.2% with a 95% Confidence Interval 95.9%-96.4%; 2.1% higher than AIR reported coverage of 94.1%. The under-reporting was mainly due to data errors at the provider level and duplicate records. Included is a peer-reviewed article that I wrote and published on the subject in the Australian and New Zealand Journal of Public Health. The data analysis project investigated the over-representation of Aboriginal people diagnosed with Q fever in NSW, particularly in Western NSW. Following indirect standardisation, we found that Aboriginal people across Western NSW were notified with Q fever almost 35% more often as non-Indigenous people living in the same area. Aboriginal people reported working in occupations such as shearing at a much younger age than non-Indigenous people. Aboriginal community governance over the public health actions that arose from this analysis is provided in detail. I led an investigation into a large protracted outbreak of Salmonella Typhimurium with a novel multi-locus variable number tandem repeat analysis type profile that affected 235 people in the Australian Capital Territory, NSW and Queensland from 10 October 2018 to 31 May 2019. The chapter describes the outbreak investigation including epidemiological, environmental and laboratory components, and control actions take [...]
