La primera semana de septiembre de 2013, el Sistema Nacional de Vigilancia Epidemiológica identificó dos casos de cólera en Ciudad de México. Los cultivos de ambas muestras se confirmaron como Vibrio cholerae serogrupo O1, serotipo Ogawa, biotipo El Tor. Los análisis iniciales por electroforesis por campos pulsados y por reacción en cadena de la polimerasa indicaron que ambas cepas eran similares, pero diferentes de las previamente reportadas en México. La semana siguiente se identificaron cuatro casos más en una comunidad del Estado de Hidalgo, ubicada a 121 kilómetros al noreste de Ciudad de México...

BACKGROUND: Rapid diagnostic tests (RDT) for cholera are promising tools for detecting cholera in areas with limited laboratory infrastructure. However, evidence on the characteristics of the many available RDTs is scarce, and their use has been limited by suboptimal performance. We evaluated the performance characteristics of three cholera RDTs from Span Diagnostics, Artron Laboratories, and Standard Diagnostics in a regional laboratory in Haiti. METHODOLOGY/PRINCIPAL FINDINGS: We retrospectively reviewed records from May 2014 to October 2015 of a laboratory-based surveillance program for Vibrio cholerae at Hôpital Saint-Nicolas in Saint-Marc, Haiti...

The devastating 2010 cholera epidemic in Haiti prompted the government to introduce oral cholera vaccine (OCV) in two high-risk areas of Haiti. We evaluated the direct costs associated with the government's first vaccine campaign implemented in August-September 2013. We analyzed data for major cost categories and assessed the efficiency of available campaign resources to vaccinate the target population. For a target population of 107,906 persons, campaign costs totaled $624,000 and 215,295 OCV doses were dispensed...

Haiti is committed to malaria elimination by 2020. Following a 2010 earthquake and cholera epidemic, Haiti capitalized on investments in its health system to refocus on malaria elimination. Efforts, including expanding diagnostics, ensuring efficacy of standard treatments, building institutional capacity, and strengthening surveillance were undertaken to complement the broad health system strengthening activities. These efforts led to the adoption and scale-up of malaria rapid diagnostic tests as a diagnostic modality...

Emergencies can often directly impact health systems of an affected region or country, especially in resource-constrained areas. Health system recovery following an emergency is a complex and dynamic process. Health system recovery efforts have often been structured around the World Health Organization's health systems building blocks as demonstrated by the Post-Disaster Needs Assessment. Although this structure is valuable and well known, it can overlook the intricacies of public health systems. We retrospectively examine public health systems recovery, a subset of the larger health system, following the 2010 Haiti earthquake and cholera outbreak, through the lens of the 10 essential public health services...

Before the 2010 devastating earthquake and cholera outbreak, Haiti's public health laboratory systems were weak and services were limited. There was no national laboratory strategic plan and only minimal coordination across the laboratory network. Laboratory capacity was further weakened by the destruction of over 25 laboratories and testing sites at the departmental and peripheral levels and the loss of life among the laboratory health-care workers. However, since 2010, tremendous progress has been made in building stronger laboratory infrastructure and training a qualified public health laboratory workforce across the country, allowing for decentralization of access to quality-assured services...

As cholera spread from Haiti to the Dominican Republic, Haitian migrants, a largely undocumented and stigmatized population in Dominican society, became a focus of public health concern. Concurrent to the epidemic, the Dominican legislature enacted new documentation requirements. This paper presents findings from an ethnographic study of anti-Haitian stigma in the Dominican Republic from June to August 2012. Eight focus group discussions (FGDs) were held with Haitian and Dominican community members. Five in-depth interviews were held with key informants in the migration policy sector...

BACKGROUND: Case-control studies to quantify oral cholera vaccine effectiveness (VE) often rely on neighbors without diarrhea as community controls. Test-negative controls can be easily recruited and may minimize bias due to differential health-seeking behavior and recall. We compared VE estimates derived from community and test-negative controls and conducted bias-indicator analyses to assess potential bias with community controls. METHODS: From October 2012 through November 2016, patients with acute watery diarrhea were recruited from cholera treatment centers in rural Haiti...

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...

Oral cholera vaccination was used as part of cholera control in Haiti, but the vaccine does not provide complete protection. We conducted secondary data analyses of a vaccine effectiveness study in Haiti to evaluate risk factors for cholera among cholera vaccine recipients. Individuals vaccinated against cholera that presented with acute watery diarrhea and had a stool sample positive for Vibrio cholerae O1 were included as cases. Up to four vaccinated individuals who did not present for treatment of diarrhea were included as controls for each case, and matched by location of residence, enrollment time, and age...

The large outbreak of cholera reported during July to September 2014 in the Narla block of Kalahandi district, India, was investigated to determine the causative organism. Rectal swabs collected from patients with diarrhea and environmental water samples were cultured following standard techniques. The causative organism was identified as Vibrio cholerae O1 Ogawa biotype El Tor, and analysis by double mismatch mutation assay PCR confirmed that all strains were the ctxB7 variant of Haitian V. cholerae O1. The environmental water samples were negative for V...

Vibrio cholerae O1 is the etiological agent of the severe diarrheal disease cholera. The bacterium has recently been causing outbreaks in Haiti with catastrophic effects. Numerous mutations have been reported in V. cholerae O1 strains associated with the Haitian outbreak. These mutations encompass among other the genes encoding virulence factors such as the pilin subunit of the toxin-co-regulated pilus (tcpA), cholera toxin B subunit (ctxB), repeat in toxins (rtxA), and other genes such as the quinolone resistance-determining region (QRDR) of gyrase A (gyrA), rstB of RS element along with the alteration in the number of repeat sequences at the promoter region of ctxAB...

BACKGROUND: Haiti has the worst malnutrition rate in the Western hemisphere. In October 2010, a cholera epidemic erupted and spread rapidly throughout the country, straining Haiti's already fragile health infrastructure across all levels of care. This study reviews data from an outpatient therapeutic feeding program (OTP) for acute childhood malnutrition at a clinic in rural Haiti with a focus on the effect of the 2010 cholera epidemic on program operations. METHODS: A retrospective chart review was conducted for the complete set of patients who were enrolled in the OTP from its inception in March 2009 through January 2014...

More than 5 years after a United Nations peacekeeping battalion introduced cholera to Haiti, over 150,000 peacekeepers continue to be deployed annually from countries where cholera is endemic. The United Nations has thus far declined to provide antimicrobial chemoprophylaxis to peacekeepers, a policy based largely on concerns that the risks of drug resistance generation and spread would outweigh the potential benefits of preventing future cholera importations. In this study, we sought to better understand the relative benefits and risks of cholera chemoprophylaxis for peacekeepers in terms of antibiotic resistance...

Cholera, caused by infection with toxigenic Vibrio cholerae bacteria of serogroup O1 (>99% of global cases) or O139, is characterized by watery diarrhea that can be severe and rapidly fatal without prompt rehydration. Cholera is endemic in approximately 60 countries and causes epidemics as well. Globally, cholera results in an estimated 2.9 million cases of disease and 95,000 deaths annually (1). Cholera is rare in the United States, and most U.S. cases occur among travelers to countries where cholera is endemic or epidemic...

Following the 2010 cholera outbreak in Haiti, a plan was initiated to provide massive improvements to the sanitation and drinking water infrastructure in order to eliminate cholera from the island of Hispaniola by 2023. Six years and a half billion dollars later, there is little evidence that any substantial improvements have been implemented; with increasing evidence that cholera has become endemic. Thus, it is time to explore strategies to control cholera in Haiti using oral cholera vaccines (OCVs). The potential effects of mass administration of OCVs on cholera transmission were assessed using dynamic compartment models fit to cholera incidence data from the Ouest Department of Haiti...

Cholera, present in Haiti since October 2010, persisted in early 2014 in several places, each with its own particular epidemiological characteristics. The scarcity of fresh water probably contributed to the spread of the disease in some rural areas. Population gatherings in places without an access to either safe water or sanitation infrastructure were another factor. Outreach activities of hygiene promotion and improving access to chlorinated water had positive results. The disappearance of choléra in areas where effective preventive actions were conducted supports the conclusion that its transmission is predominantly interhuman, without the sustainable installation of the pathogenic Vibrio in the Haitian environment...

On 19 October 2010, ten months after a devastating earthquake hit Haiti, the Haitian Ministry of Public Health and Population (MSPP) was notified of a sudden surge in patients suffering from watery diarrhea and dehydration. Two days later, the Haiti National Public Health Laboratory identified the culprit: Vibrio cholerae. On 22 October, officials announced the first cholera outbreak in Haiti in more than a century.
