Community engagement is crucial for public health initiatives, yet it remains an under-studied process within national disease elimination programs. This report shares key lessons learned for community engagement practices during a malaria outbreak response in the Los Tres Brazos neighborhood of urban Santo Domingo, Dominican Republic from 2015-2016. In this two-year period, 233 cases of malaria were reported—more than seven times the number of cases (31) reported in the previous two years. The initial outbreak response by the national malaria program emphasized “top-down” interventions such as active surveillance, vector control, and educative talks within the community. Despite a transient reduction in reported cases in mid-2015, transmission resurged at the end of 2015. The program responded by introducing active roles for trained community members that included door-to-door fever screening, testing with rapid diagnostic tests and treatment. Malaria cases declined significantly throughout 2016 and community-based active surveillance infrastructure helped to detect and limit a small episode of transmission in 2017. Results from qualitative research among community members revealed two key factors that facilitated their cooperation with community-based surveillance activities: motivation to help one’s community; and trust among stakeholders (community health workers, their neighbors and other key figures in the community, and malaria program staff and leadership). This experience suggests that community-led interventions and the program’s willingness to learn and adapt under changing circumstances can help control malaria transmission and pave the way for elimination.

Abstract Background In April 2017, the Thai Ministry of Public Health (MoPH) was alerted to a potential malaria outbreak among civilians and military personnel in Sisaket Province, a highly forested area bordering Cambodia. The objective of this study was to present findings from the joint civilian-military outbreak response. Methods A mixed-methods approach was used to assess risk factors among cases reported during the 2017 Sisaket malaria outbreak. Routine malaria surveillance data from January 2013 to March 2018 obtained from public and military medical reporting systems and key informant interviews (KIIs) (n = 72) were used to develop hypotheses about potential factors contributing to the outbreak. Joint civilian-military response activities included entomological surveys, mass screen and treat (MSAT) and vector control campaigns, and scale-up of the “1–3–7” reactive case detection approach among civilians alongside a pilot “1–3–7” study conducted by the Royal Thai Army (RTA). Results Between May–July 2017, the monthly number of MoPH-reported cases surpassed the epidemic threshold. Outbreak cases detected through the MoPH mainly consisted of Thai males (87%), working as rubber tappers (62%) or military/border police (15%), and Plasmodium vivax infections (73%). Compared to cases from the previous year (May–July 2016), outbreak cases were more likely to be rubber tappers (OR = 14.89 [95% CI: 5.79–38.29]; p < 0.001) and infected with P. vivax (OR=2.32 [1.27–4.22]; p = 0.006). Themes from KIIs were congruent with findings from routine surveillance data. Though limited risk factor information was available from military cases, findings from RTA’s “1–3–7” study indicated transmission was likely occurring outside military bases. Data from entomological surveys and MSAT campaigns support this hypothesis, as vectors were mostly exophagic and parasite prevalence from MSAT campaigns was very low (range: 0-0.7% by PCR/microscopy). Conclusions In 2017, an outbreak of mainly P. vivax occurred in Sisaket Province, affecting mainly military and rubber tappers. Vector control use was limited to the home/military barracks, indicating that additional interventions were needed during high-risk forest travel periods. Importantly, this outbreak catalyzed joint civilian-military collaborations and integration of the RTA into the national malaria elimination strategy (NMES). The Sisaket outbreak response serves as an example of how civilian and military public health systems can collaborate to advance national malaria elimination goals in Southeast Asia and beyond.

Bhutan experienced its largest and first nation-wide dengue epidemic in 2019. The cases in 2019 were greater than the total number of cases in all the previous years. This study aimed to characterize the spatiotemporal patterns and effective reproduction number of this explosive epidemic. Weekly notified dengue cases were extracted from the National Early Warning, Alert, Response and Surveillance (NEWARS) database to describe the spatial and temporal patterns of the epidemic. The time-varying, temperature-adjusted cohort effective reproduction number was estimated over the course of the epidemic. The dengue epidemic occurred between 29 April and 8 December 2019 over 32 weeks, and included 5935 cases. During the epidemic, dengue expanded from six to 44 subdistricts. The effective reproduction number was <3 for most of the epidemic period, except for a ≈1 month period of explosive growth, coinciding with the monsoon season and school vacations, when the effective reproduction number peaked >30 and after which the effective reproduction number declined steadily. Interventions were only initiated 6 weeks after the end of the period of explosive growth. This finding highlights the need to reinforce the national preparedness plan for outbreak response, and to enable the early detection of cases and timely response.

Abstract Background This study aimed to assess the level of trust in the COVID-19 risk communication efforts in Nigeria. Methods We conducted a descriptive cross-sectional study among community members aged 15 years and above in Ondo state in October, 2020. Data were collected using an interviewer-administered questionnaire. Data were analyzed using SPSS version 22. Descriptive statistics were summarized using frequencies. Trust was ranked from “1” implying “Low level of trust” to “7” denoting “High level of trust”. We conducted bivariate Chi-square test on respondents’ level of trust in the Nigeria Centre for Disease Control (NCDC) and socio-demographic characteristics. The level of significance was set at p<0.05. Results Among the 691 respondents, 244 (35.3%) were aged 21 to 29 years, and 304 (51.4%) used the NCDC to obtain COVID-19 knowledge. Overall, 205 (41.8%) had high level of trust in the NCDC. Furthermore, 51 (51.5%) individuals aged 30-39 years had high level of trust in the NCDC (ᵡ2=17.455, p= 0.001). Also, 114 (48.5%) persons who lived with children below 18 years had high level of trust in the NCDC (ᵡ2= 8.266, p= 0.004). Conclusion Policy makers should prioritize the involvement of young and educated persons in COVID-19 risk communication strategies.

Abstract Background: From January to May 2019, large measles outbreaks affected Nigeria. Borno state was the most affected, recording 15,237 suspected cases with the state capital of Maiduguri having 1,125 cases investigated and line-listed by March 2019. In Borno state, 22 of the 27 Local Government Areas (LGAs or Districts), including 37 internally displaced persons (IDPs) camps were affected. In response to the situation, an outbreak response immunization (ORI) campaign was conducted in the 13 most affected LGAs. In addition to conventional vaccination teams, special teams were deployed in security compromised areas, areas with migrants, and for nomadic and IDPs. Here we describe the outbreak and the ORI campaign. We also assess the measles-containing vaccine (MCV) coverage and vaccine effectiveness (VE) in order to quantify the population-level impactMethods: We reviewed the ORI activities, and conducted an analysis of the surveillance and the outbreak investigation reports. We assessed VE of MCV by applying the screening-method. Sensitivity analyses were also conducted to assess the effect of final classification of cases on the VE of MCV. The MCV coverage was assessed by a post-campaign coverage survey (PCCS) after completion of the ORI through a quantitative survey in the 12 LGAs that were accessible. . Results: Of the total 15,237 reported measles cases, 2,002 cases were line-listed and investigated, and 737 were confirmed for measles by week 9 of 2019. Of the investigated cases 67.3% (n = 1,348) were between 9 and 59 months of age. Among the 737 confirmed cases, only 9% (n = 64) stated being vaccinated with at least 1 dose of MCV. The overall VE for MCV was 98.4 (95%CI: 97.8 – 98.8). No significant differences were observed in the VE estimates of lab-confirmed and epi-linked cases when compared to the original estimates. The aggregated weighted vaccination coverage was 85.7% (95% CI: 79.6 – 90.1).Conclusion: The experience in Borno demonstrates that adequate VE can be obtained in conflict-affected areas. In complex emergency affected by measles outbreaks, health authorities may consider integration with other health strategies and the engagement of security personnel as part of the ORI activities.
