RESUMO

In October 2010, the Haitian Ministry of Public Health and Population (MSPP; Port au Prince, Haiti) reported a cholera epidemic caused by contamination of the Artibonite River by a United Nation Stabilization Mission camp. Interventional studies of the subsequent responses, including a descriptive Methods section and systematic approach, may be useful in facilitating comparisons and applying lessons learned to future outbreaks. The purpose of this study was to examine publicly available documents relating to the 2010 cholera outbreak to answer: (1) What information is publicly available on interventional studies conducted during the epidemic, and what was/were the impact(s)? and (2) Can the interventions be compared, and what lessons can be learned from their comparison? A PubMed (National Center for Biotechnology Information, National Institutes of Health; Bethesda, Maryland USA) search was conducted using the parameters "Haiti" and "cholera." Studies were categorized as "interventional research," "epidemiological research," or "other." A distinction was made between studies and narrative reports. The PubMed search yielded 171 papers, 59 (34.0%) of which were epidemiological and 12 (7.0%) were interventional studies. The remaining 100 papers (59.0%) comprised largely of narrative, anecdotal descriptions. An expanded examination of publications by the World Health Organization (WHO; Geneva, Switzerland), the Center for Research in the Epidemiology of Disasters (CRED; Brussels, Belgium), United States Agency for International Development (USAID; Washington, DC USA)-Development Experience Clearinghouse (DEC), and US National Library of Medicine's (NLM; Bethesda, Maryland USA) Disaster Literature databases yielded no additional interventional studies. The unstructured formats and differing levels of detail prohibited comparisons between interventions, even between those with a similar approach. Only two (17.0%) interventional studies included any impact data, although neither commented whether the intervention improved health or reduced incidence or mortality related to cholera. Agreed frameworks for guiding responses and subsequent reporting are needed to ensure reports contain sufficient detail to draw conclusions for the definition of best practices and for the design of future interventions.

RESUMO

Damage to the inferior and fragile water and sanitation infrastructure of Haiti after Hurricane Matthew has created an urgent public health emergency in terms of likelihood of cholera occurring in the human population. Using satellite-derived data on precipitation, gridded air temperature, and hurricane path and with information on water and sanitation (WASH) infrastructure, we tracked changing environmental conditions conducive for growth of pathogenic vibrios. Based on these data, we predicted and validated the likelihood of cholera cases occurring past hurricane. The risk of cholera in the southwestern part of Haiti remained relatively high since November 2016 to the present. Findings of this study provide a contemporary process for monitoring ground conditions that can guide public health intervention to control cholera in human population by providing access to vaccines, safe WASH facilities. Assuming current social and behavioral patterns remain constant, it is recommended that WASH infrastructure should be improved and considered a priority especially before 2017 rainy season.

RESUMO

In 2010, the nation of Haiti was leveled by a shattering earthquake that killed thousands and devastated its already fragile infrastructure. During relief efforts to aid Haiti's suffering population, the United Nations sent troops to Haiti to assist the rebuilding of country's most basic services. But those troops unknowingly carried with them the bacteria that cause cholera, and through the UN's negligent actions, it triggered a horrifying cholera epidemic that continues to harm the Haitian people. Those injured by the cholera epidemic have sought relief in the US federal court system to obtain justice for those killed or sickened by the cholera outbreak. The UN has declared legal immunity for causing the epidemic, yet the litigation on this matter is ongoing.

RESUMO

US cholera surveillance offers insight into global and domestic trends. Between 2001 and 2011, 111 cases were reported to the Centers for Disease Control and Prevention. Cholera was associated with international travel in 90 (81%) patients and was domestically acquired in 20 (18%) patients; for one patient, information was not available. From January 2001 to October 2010, the 42 (47%) travel-associated cases were associated with travel to Asia. In October 2010, a cholera epidemic started in Haiti, soon spreading to the Dominican Republic (Hispaniola). From then to December 2011, 40 (83%) of the 48 travel-associated cases were associated with travel to Hispaniola. Of 20 patients who acquired cholera domestically, 17 (85%) reported seafood consumption; 10 (59%) ate seafood from the US Gulf Coast. In summary, an increase in travel-associated US cholera cases was associated with epidemic cholera in Hispaniola in 2010-2011. Travel to Asia and consumption of Gulf Coast seafood remained important sources of US cholera cases.

RESUMO

In the Americas, the only two cholera epidemics of the past century have occurred in the past 25 years. Lessons from the 1991 Peruvian cholera epidemic can help to focus and refine the response to the current Haitian epidemic. After three years of acute epidemic response, we have an opportunity to refocus on the chronic conditions that make societies vulnerable to cholera. More importantly, even as international attention wanes in the aftermath of the earthquake and acute epidemic, we are faced with a need for continued and coordinated investment in improving Haiti's structural defenses against cholera, in particular access to improved water and sanitation.

RESUMO

Aborda as mudanças ocorridas nas práticas da profilaxia marítima brasileira. Por meio de dois casos de navios de imigrantes, que chegaram ao porto do Rio de Janeiro com epidemias a bordo, são analisados a compreensão sobre a etiologia, a forma de prevenção e o combate às três doenças com regulamentação portuária internacional: febre amarela, peste bubônica e cólera. Até o final do século XIX, uma das principais práticas de profilaxia era a quarentena. No início do XX, identificamos a emergência do ideário da microbiologia e dos vetores no serviço sanitário dos portos. A quarentena, que já vinha sendo criticada como antiquada e ineficaz, é limitada a alguns casos, e novos métodos e tecnologias da higiene passam a ser aplicados na defesa sanitária dos portos.

We address the changes in Brazilian maritime prophylaxis by studying two cases of immigrant ships arriving at the port of Rio de Janeiro with epidemics onboard. The objective is to understand the etiology, means of prevention and methods used to combat the three diseases subject to international port regulations: yellow fever, bubonic plague and cholera. Until the late nineteenth century, quarantines were one of the main disease prevention practices. In the early twentieth century, microbiology and the concept of vectors in ports sanitation services emerged. Quarantines, which were already being criticized as antiquated and ineffective, were limited to a few cases, and new hygiene methods and technologies began to be applied in port sanitary defense.

RESUMO

We conducted a case­control study of a cholera outbreak after a wedding in the Dominican Republic, January 22, 2011. Ill persons were more likely to report having consumed shrimp on ice (odds ratio 8.50) and ice cubes in beverages (odds ratio 3.62). Travelers to cholera affected areas should avoid consuming uncooked seafood and untreated water.
