“…Genetic characterization of the index isolates in nearly all cVDPV outbreaks suggested transmission for many years, indicating imprecise AFP surveillance systems. Indonesia and Papua New Guinea had last reported polio cases more than a decade ago; in both countries, there has been low routine immunization coverage before the emergence and spread of independent cVDPV1 ( 10 ). The multiple cVDPV2 outbreaks in DRC and Nigeria reflect the risk for cVDPV2 transmission where the number of SIAs had been insufficient or the quality of SIAs had been inadequate to increase type 2 immunity before the 2016 global switch from tOPV to bOPV ( 9 ).…”

“…During January 2018–June 2019, cVDPV type 1 (cVDPV1) circulation was detected in three countries (Indonesia, Myanmar, and Papua New Guinea), compared with one country (Papua New Guinea) during the previous reporting period ( 3 ). cVDPV1 isolates from acute flaccid paralysis (AFP) cases and environmental surveillance (testing of sewage samples for poliovirus) continued to be detected from the previously reported Papua New Guinea outbreak ( 4 ) (Table); the AFP patient with the latest case had paralysis onset in October 2018. A new cVDPV1 outbreak was reported in Myanmar; the first patient had paralysis onset in May 2019, and the most recent case occurred in August 2019.…”

“…The recent detection of 26 circulating vaccine‐derived poliovirus type 1 cases in Papua New Guinea (PNG) [8] and a measles epidemic in Samoa that claimed 83 lives [9] highlights the vulnerability of PICTs to outbreaks. Given the maturity and resourcing of polio and measles surveillance compared to other epidemic detection systems, it is plausible that many other disease outbreaks go undetected [10].…”

Objective Due to their tropical location, development status and the limited capacity of health systems, Pacific island counties and territories are particularly susceptible to infectious disease outbreaks; but evidence as to the optimal way in which outbreaks are detected is scarce. In this review, we synthesise evidence from literature about how outbreaks are detected in Pacific island countries and territories and critique factors identified as inhibiting surveillance practice. Method For this systematic review, we searched electronic databases Embase, Global Health, MEDLINE and MEDLINE Epub from 1 January 2010 and 31 March 2019 for reports describing infectious disease outbreaks occurring in the Pacific islands. Reports were included if they reported the method by which an outbreak was detected or the time between an outbreak’s onset and its detection. We extracted information about the report type and authors, the outbreak and its method/s of detection, and pertinent issues inhibiting surveillance practice. Results Of 860 articles identified, 37 reports describing 39 outbreaks met the inclusion criteria. Most outbreaks (n = 30) were identified through formal event‐based surveillance; six through syndromic surveillance; and two by ad hoc notification from the community. Barriers to early outbreak detection included population isolation; lack of resources and infrastructure to support surveillance implementation and signal investigation; and broader health system factors such as preparedness planning and availability of laboratory services. Conclusion Most surveillance‐related gain in the Pacific islands may be made through building formal event‐based surveillance systems and streamlining reporting processes to facilitate outbreak notification. This observation is pertinent given the focus on establishing and expanding syndromic surveillance approaches for outbreak detection in the islands over the last decade.
