In industrialized societies, most survivors of traumatizing violence experience symptoms only transiently. In the Rwanda survey, symptom levels and rates of 'probable PTSD' were exceptionally elevated, suggesting that at the limits of catastrophic man-made violence, psychological resilience among youth is all but extinguished.
Mental health distress and disability are pervasive issues among the US Gulf Coast adults and children who experienced long-term displacement or other serious effects as a result of Hurricanes Katrina and Rita. As time progresses postdisaster, social and psychological factors may play greater roles in accelerating or impeding recovery among affected populations. Efforts to expand disaster recovery and preparedness policies to include long-term social re-engagement efforts postdisaster should be considered as a means of reducing mental health sequelae.
BackgroundDuring December 2014–February 2015, an Ebola outbreak in a village in Kono district, Sierra Leone, began following unsafe funeral practices after the death of a person later confirmed to be infected with Ebola virus. In response, disease surveillance officers and community health workers, in collaboration with local leadership and international partners, conducted 1 day of active surveillance and health education for all households in the village followed by ongoing outreach. This study investigated the impact of these interventions on the outbreak.MethodsFifty confirmed Ebola cases were identified in the village between December 1, 2014 and February 28, 2015. Data from case investigations, treatment facility and laboratory records were analyzed to characterize the outbreak. The reproduction number (R) was estimated by fitting to the observed distribution of secondary cases. The impact of the active surveillance and health education was evaluated by comparing two outcomes before and after the day of the interventions: 1) the number of days from symptom onset to case-patient isolation or death and 2) a reported epidemiologic link to a prior Ebola case.ResultsThe case fatality ratio among the 50 confirmed Ebola cases was 64.0 %. Twenty-three cases occurred among females (46.0 %); the mean age was 39 years (median: 37 years; range: 5 months to 75 years). Forty-three (87.8 %) cases were linked to the index case; 30 (61.2 %) were either at the funeral of Patient 1 or had contact with him while he was ill. R was 0.93 (95 % CI: 0.15–2.3); excluding the funeral, R was 0.29 (95 % CI: 0.11–0.53). The mean number of days in the community after onset of Ebola symptoms decreased from 4.0 days (median: 3 days; 95 % CI: 3.2–4.7) before the interventions to 2.9 days (median: 2 days; 95 % CI: 1.6–4.3) afterward. An epidemiologic link was reported in 47.6 % of case investigations prior to and 100 % after the interventions.ConclusionsInitial case investigation and contact tracing were hindered by delayed reporting and under-reporting of symptomatic individuals from the community. Active surveillance and health education contributed to quicker identification of suspected cases, interrupting further transmission.
The International Health Regulations (2005) dictate the need for states parties to establish capacity to respond promptly and effectively to public health risks. Public health rapid response teams (RRTs) can fulfill this need as a component of a larger public health emergency response infrastructure. However, lack of a standardized approach to establishing and managing RRTs can lead to substantial delays in effective response measures. As part of the Global Health Security Agenda, national governments have sought to develop and more formally institute their RRTs. RRT challenges were identified from 21 countries spanning 4 continents from 2016 to 2018 through direct observation of RRTs deployed during public health emergencies, discussions with RRT managers involved in outbreak response, and during formal RRT management training workshops. One major challenge identified is the development and maintenance of an RRT roster to ensure deployable surge staff identification, selection, and availability. Another challenge is ensuring that RRT members are trained and have the relevant competencies to be effective in the field. Finally, the lack of defined RRT standard operating procedures covering both nonemergency maintenance measures and the multistage emergency response processes required for RRT function can delay the RRT's response time and effectiveness. These findings highlight the importance of planning to preemptively address these challenges to ensure rapid and effective response measures, ultimately strengthening global health security.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
