Rapid ethnographic assessment for potential anti-malarial mass drug administration in an outbreak area of Santo Domingo, Dominican Republic.

BACKGROUND: In the Dominican Republic, a recent outbreak of malaria in the capital, Santo Domingo, threatens efforts to eliminate the disease. Mass drug administration (MDA) has been proposed as one strategy to reduce transmission. The success of MDA is contingent upon high levels of acceptance among the target population. To inform the design of future MDA campaigns, this rapid ethnographic assessment examined malaria-related knowledge and attitudes toward malaria MDA among residents of a transmission focus in Santo Domingo. METHODS: In October 2019, a rapid ethnographic assessment was conducted in the Los Tres Brazos transmission focus, which had not previously received MDA. National malaria programme staff conducted 61 structured interviews with key informants, recorded observations, and held 72 informal conversations. Using a grounded theory approach, data were analysed during three workshop sessions with research team members. RESULTS: Among those who had heard of malaria in the structured interviews (n = 39/61; 64%), understanding of the disease was largely based on personal experience from past outbreaks or through word-of-mouth. Community health workers (promotores) were trusted for health information and malaria diagnosis more so than professional clinicians. No participant (0%) was familiar with malaria MDA. After learning about MDA, almost all study participants (92%) said that they would participate, seeing it as a way to care for their community. Reasons for not participating in future MDA included not trusting drug administrators, feeling reluctant to take unprescribed medicine, and fear of missing work. Additional identified challenges to MDA included reaching specific demographic groups, disseminating effective MDA campaign messages, and managing misinformation and political influence. CONCLUSION: Residents appear accepting of MDA despite a lack of prior familiarity. Successful MDA will depend on several factors: fostering relationships among community-based health workers, clinicians, community leaders, and others; developing clear health messages that use local terms and spreading them through a variety of media and social networks; and contextualizing MDA as part of a broader effort to promote community health.

Malaria outbreak response in urban Santo Domingo, Dominican Republic: lessons learned for community engagement.

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.

La participación de la comunidad es crucial para las iniciativas de salud pública, pero sigue siendo un proceso poco estudiado dentro de los programas nacionales de eliminación de enfermedades. En este informe se presentan las principales lecciones aprendidas respecto de las prácticas de participación comunitaria durante la respuesta al brote de malaria en el barrio Los Tres Brazos de la zona urbana de Santo Domingo, República Dominicana, de 2015 a 2016. En este período de dos años se notificaron 233 casos de malaria, más de siete veces el número de casos (31) notificados en los dos años anteriores. La respuesta inicial al brote por parte del programa nacional de malaria hizo hincapié en intervenciones "de arriba abajo" como la vigilancia activa, el control de vectores y las charlas educativas dentro de la comunidad. A pesar de la reducción transitoria de los casos notificados hacia mediados de 2015, la transmisión resurgió a finales de ese año. El programa respondió introduciendo funciones activas para miembros de la comunidad capacitados que incluían la detección de fiebre de casa en casa, pruebas de diagnóstico rápido y tratamiento. Los casos de malaria disminuyeron significativamente durante 2016 y la infraestructura de vigilancia activa basada en la comunidad ayudó a detectar y contener un episodio pequeño de transmisión en 2017. Los resultados de la investigación cualitativa entre los miembros de la comunidad revelaron dos factores clave que facilitaron su cooperación con las actividades de vigilancia basadas en la comunidad: la motivación para ayudar a la propia comunidad y la confianza entre las partes interesadas (los trabajadores sanitarios de la comunidad, los vecinos y otros actores clave de la comunidad, y el personal y la dirección del programa de lucha contra la malaria). Esta experiencia indica que las intervenciones dirigidas por la comunidad y la voluntad del programa de aprender y adaptarse a las circunstancias cambiantes pueden ayudar a controlar la transmisión de la malaria y facilitar el camino para su eliminación.

Results from a Knowledge, Attitudes, and Practices Survey in Two Malaria Transmission Foci of Santo Domingo, Dominican Republic.

Metropolitan Santo Domingo has accounted for a majority of reported malaria cases in the Dominican Republic in recent years. To inform malaria control and elimination efforts, a cross-sectional survey of malaria knowledge, attitudes, and practices collected 489 adult household-level questionnaires across 20 neighborhoods in the city's two main transmission foci, Los Tres Brazos (n = 286) and La Ciénaga (n = 203), in December 2020. Overall, most residents (69%) were aware of the problem of malaria in Santo Domingo, but less than half knew that mosquitos transmit the disease (46%) or took any correct preventative measure (45%). More residents of Los Tres Brazos, where malaria incidence is higher than in La Ciénaga, said that they had never been visited by active surveillance teams (80% versus 66%, respectively; P = 0.001), did not link mosquitos with malaria transmission (59% versus 48%, P = 0.013), and did not know medication can cure malaria (42% versus 27%, P = 0.005). Fewer residents of Los Tres Brazos said that malaria was a problem in their neighborhoods (43% versus 49%, P = 0.021) and fewer had mosquito bed nets in their homes (42% versus 60%, P < 0.001). The majority (75%) of questionnaire respondents in both foci did not have enough mosquito nets for all household residents. These findings demonstrate gaps in malaria knowledge and community-based interventions and highlight the need to improve community engagement for malaria elimination in affected areas of Santo Domingo.
