Spatio-temporal dynamics of cholera during the first year of the epidemic in Haiti.

BACKGROUND: In October 2010, cholera importation in Haiti triggered an epidemic that rapidly proved to be the world's largest epidemic of the seventh cholera pandemic. To establish effective control and elimination policies, strategies rely on the analysis of cholera dynamics. In this report, we describe the spatio-temporal dynamics of cholera and the associated environmental factors. METHODOLOGY/PRINCIPAL FINDINGS: Cholera-associated morbidity and mortality data were prospectively collected at the commune level according to the World Health Organization standard definition. Attack and mortality rates were estimated and mapped to assess epidemic clusters and trends. The relationships between environmental factors were assessed at the commune level using multivariate analysis. The global attack and mortality rates were 488.9 cases/10,000 inhabitants and 6.24 deaths/10,000 inhabitants, respectively. Attack rates displayed a significantly high level of spatial heterogeneity (varying from 64.7 to 3070.9 per 10,000 inhabitants), thereby suggesting disparate outbreak processes. The epidemic course exhibited two principal outbreaks. The first outbreak (October 16, 2010-January 30, 2011) displayed a centrifugal spread of a damping wave that suddenly emerged from Mirebalais. The second outbreak began at the end of May 2011, concomitant with the onset of the rainy season, and displayed a highly fragmented epidemic pattern. Environmental factors (river and rice fields: p<0.003) played a role in disease dynamics exclusively during the early phases of the epidemic. CONCLUSION: Our findings demonstrate that the epidemic is still evolving, with a changing transmission pattern as time passes. Such an evolution could have hardly been anticipated, especially in a country struck by cholera for the first time. These results argue for the need for control measures involving intense efforts in rapid and exhaustive case tracking.

Uptake to HIV post-exposure prophylaxis in Haiti: opportunities to align sexual violence, HIV PEP and mental health.

Sexual violence is a public health problem in Haiti, potentially augmenting HIV transmission. Reports from L'Hôpital de l'Université d'État d'Haiti (HUEH) suggest severe underutilization of antiretroviral post-exposure prophylaxis (ARV-PEP) among rape survivors. Cross-sectional design using mixed methods. Informational interviews were conducted with HUEH personnel to learn about post-rape service offerings. HUEH surveillance data were used to estimate the sexual assault reporting rate/100,000 and to examine the proportion of survivors receiving ARV-PEP within 72 hr, stratified by age (<18 years, ≥18 years). Informational interviews revealed that survivors were navigated through two hospital algorithms to receive post-rape care; however, <5% of victims sought mental health services. Surveillance data show that 2193 sexual assault survivors (adult and pediatric) reported a rape to HUEH personnel between 2004 through first quarter of 2010. Annual estimates suggest a twofold increase comparing cases in 2004 versus 2009. Between 2008 and 2009, uptake to ARV-PEP within 72 hr was lower for pediatric (38.4%; N = 131/341) compared with adult survivors (60.1%; N = 83/138) (χ(2)  = 18.8, P < 0.001). The prioritization of funding and comprehensive interventions that align sexual violence, HIV, and mental health is crucial to support the timely uptake to ARV-PEP.

Reporte final: uso de condones en República Dominicana y Haití-1990 / Final report: condons use in the Dominican Republic and Haiti, 1990

En interes de analizar las tendencias en las informaciones recogidas, así como determinar los patrones y perfiles de los usuarios, se realizó el estudio que incluyó encuestas de observación en hoteles y moteles, donde previamente se colocaron condones de diferentes marcas y fechas de manufactura y material impreso para el uso correcto del condón; cuando el cliente abandonaba la habitación el equipo encuestador entraba y observaba el uso dado a los condones. Los resultados indicaron que la prevalencia de uso de condón está disminuyendo en Santo Domingo; el uso de condón en los establecimientos encuestados en Haití está aumentando; los materiales educativos no influyen significativamente; las roturas del condón varían según fechas de manufacturas y presencia de información
