Infectious disease outbreaks are increasingly recognised as events that exacerbate impacts or prolong recovery following disasters. Yet, our understanding of the frequency, geography, characteristics and risk factors of post-disaster disease outbreaks globally is lacking. This limits the extent to which disease outbreak risks can be prepared for, monitored and responded to following disasters. Here, we conducted a global systematic review of post-disaster outbreaks and found that outbreaks linked to conflicts and hydrological events were most frequently reported, and most often caused by bacterial and water-borne agents. Lack of adequate WASH facilities and poor housing were commonly reported risk factors. Displacement, through infrastructure damage, can lead to risk cascades for disease outbreaks; however, displacement can also be an opportunity to remove people from danger and ultimately protect health. The results shed new light on post-disaster disease outbreaks and their risks. Understanding these risk factors and cascades, could help improve future region-specific disaster risk reduction.

IntroductionDisasters have many forms, including those related to natural hazards and armed conflict. Human-inducedglobal change, such as climate change, may alter hazard parameters of these disasters. These alterations canhave serious consequences for vulnerable populations, which often experience post-disaster infectiousdisease outbreaks, leading to morbidity and mortality. The risks and drivers for these outbreaks and theirability to form cascades, are somewhat contested. Despite evidence for post-disaster outbreaks, reviewsquantifying them have been on short time scales, specific geographic areas or specific hazards. This reviewaims to fill this gap and gain a greater understanding of the risk factors involved in these contextualoutbreaks on a global level.Methods and analysisUsing the PRISMA-P 2015 checklist and Khan’s methodological framework, a systematic search strategywill be created and carried out in August 2020. The strategy will search MEDLINE, Embase andGlobalHealth electronic databases and reference lists of selected literature will also be screened. Eligiblestudies will include any retrospective cross-sectional, case-control or cohort studies investigating aninfectious disease outbreak in a local disaster affected population. Studies will not be excluded based ongeographic area or publication date. Excluded papers will include non-English studies, reviews, single casestudies and research discussing general risk factors, international refugee camps, public health, mental healthand other non-communicable diseases, pathogen genetics or economics. Following selection, data will beextracted into a data charting form, that will be reviewed by other members of the team. The data will thenbe analysed both numerically and narratively.Ethics and disseminationOnly secondary data will be used and there will be no public or patient involvement; therefore, no ethicalapproval is needed. Our findings will aim to be disseminated through a peer-reviewed journal.
