Access and coverage of malaria services in Haiti in the context of elimination: a scoping review of the literature.

Introduction: Haiti is on the verge of possibly eliminating malaria, an endemic parasitic infection primarily caused by Plasmodium falciparum on the island of Hispaniola. Owing to its associated morbidity and mortality, malaria is a leading public health priority in Haiti. This scoping review aims to identify the scope of research on access and coverage of malaria surveillance, diagnosis, and treatment in Haiti in the elimination setting.

Community end user perceptions of hessian fabric transfluthrin vapour emanators for protecting against mosquitoes under conditions of routine use in Port-au-Prince, Haiti.

Background: A treated fabric device for emanating the volatile pyrethroid transfluthrin was recently developed in Tanzania that protected against night-biting Anopheles and Culex mosquitoes for several months. Here perceptions of community end users provided with such transfluthrin emanators, primarily intended to protect them against day-active Aedes vectors of human arboviruses that often attack people outdoors, were assessed in Port-au-Prince, Haiti.

Methods: Following the distribution of transfluthrin emanators to participating households in poor-to-middle class urban neighbourhoods, questionnaire surveys and in-depth interviews of end-user households were supplemented with conventional and Photovoice-based focus group discussions.

Entomological assessment of hessian fabric transfluthrin vapour emanators as a means to protect against outdoor-biting Aedes after providing them to households for routine use in Port-au-Prince, Haiti.

Background: A simple treated fabric device for passively emanating the volatile pyrethroid transfluthrin was recently developed in Tanzania that protected against nocturnal Anopheles and Culex mosquitoes for several months. Here these transfluthrin emanators were assessed in Port-au-Prince, Haiti against outdoor-biting Aedes.

Methods: Transfluthrin emanators were distributed to participating households in poor-to-middle class urban neighbourhoods and evaluated once every two months in terms of their effects on human landing rates of wild Aedes populations.

Attitudes of medical students towards men who have sex with men living with HIV: implications for social accountability.

Objectives: To explore the attitudes that medical students in Haiti harbour toward Men who have Sex with Men living with HIV in order to better understand how stigma and other factors may impair healthcare, and to explore suggestions of opportunities in line with the values of social accountability.

Methods: This study employed a qualitative design by using a grounded theory approach regarding the context of Haiti. We used purposive sampling to select the 22 research participants.

Impact of patron saint festivities on cholera in three communes in Haiti.

Background: Religious pilgrimages are among the anthropogenic factors known to be associated with the transmission of diarrheal diseases, such as cholera. This ecological study aimed to describe the evolution of cholera and assess the relationship between the implementation of the 'coup de poing' strategy during the patron saint festivities and the incidence of cholera in the three communes of Cabaret, Carrefour, and Croix-des-Bouquets in Haiti in 2017.

Methods: An epidemiological curve was produced to illustrate the evolution of cholera at the communal level.

A realist systematic review of stigma reduction interventions for HIV prevention and care continuum outcomes among men who have sex with men.

While stigma associated with human immunodeficiency virus (HIV) infection among men who have sex with men (MSM) is well recognized, there remains relatively limited intervention data on effective stigma reduction strategies. This systematic review was conducted to highlight the mechanisms through which sexual and HIV stigma is reduced in relation to HIV prevention and care engagement. Search of PubMed and Scopus resulted in 11 tested interventions to include in our preliminary model constructed from programme frameworks and recommendations.

[Simplified Protocols for Cholera Diagnosis in the National Public Health Laboratory, Port-au-Prince, Haiti].

While the incidence of cholera is decreasing in Haiti, the time required to render stool culture results with antibiogram using the standard method practiced at the National Public Health Laboratory (LNSP) remains at an average of 80 hours. This delay can be further lengthened by the process of rendering the analysis reports to the sites of care which significantly delays the community responses to cholera. Through this study, we have aimed to assess the reliability of partial results.

[Update of knowledge on Neglected Diseases in Haiti: Mansonelliasis, Tungiasis, Leprosy, and Anthrax].

Haiti, like most limited-resources countries in the world, faces numerous neglected infectious diseases. They represent a real public health issue with lethal consequences especially in children. We are reviewing here the available literature on four neglected infectious diseases, mansonelliasis, tungiasis, leprosy and anthrax.

Mansonella ozzardi and its vectors in the New World: an update with emphasis on the current situation in Haiti.

Mansonella ozzardi (Nematoda: Onchocercidae) is a little studied filarial nematode. This human parasite, transmitted by two families of dipteran vectors, biting midges (most of them members of the genus Culicoides) and blackflies (genus Simulium), is endemic to the Neotropical regions of the New World. With a patchy geographical distribution from southern Mexico to north-western Argentina, human infection with M.

In vivo study of Plasmodium falciparum chloroquine susceptibility in three departments of Haiti.

Background: Malaria is considered a public health priority in Haiti, with a goal to eliminate by year 2020. Chloroquine is the first-line treatment recommended by the Ministry of Public Health and Population. In order to verify the suitability of chloroquine for uncomplicated malaria treatment, an in vivo study of susceptibility of Plasmodium falciparum to chloroquine was conducted from January 2013 to March 2015 in six localities in the south of Haiti.

Submicroscopic malaria infections in pregnant women from six departments in Haiti.

Objectives: To describe the epidemiology of malaria in pregnancy in Haiti.

Methods: Cross-sectional study among pregnant women in six departments of Haiti. After obtaining informed consent, whole blood samples and demographic surveys were collected to investigate malaria prevalence, anaemia and socio-behavioural risk factors for infection, respectively.

T cell subtypes and reciprocal inflammatory mediator expression differentiate P. falciparum memory recall responses in asymptomatic and symptomatic malaria patients in southeastern Haiti.

Asymptomatic Plasmodium falciparum infection is responsible for maintaining malarial disease within human populations in low transmission countries such as Haiti. Investigating differential host immune responses to the parasite as a potential underlying mechanism could help provide insight into this highly complex phenomenon and possibly identify asymptomatic individuals. We performed a cross-sectional analysis of individuals who were diagnosed with malaria in Sud-Est, Haiti by comparing the cellular and humoral responses of both symptomatic and asymptomatic subjects.

High prevalence of asymptomatic malaria infections: a cross-sectional study in rural areas in six departments in Haiti.

Background: Public health measures are poised for transition from malaria control to malaria elimination on the island of Hispaniola. Assessment of the reservoir of asymptomatic infections from which acute malaria cases may derive is critical to plan and evaluate elimination efforts. Current field technology is ill suited for detecting sub-microscopic infections, thus highly sensitive survey methods capable of detecting virtually all infections are needed.

Shaking the Tree: Multi-locus Sequence Typing Usurps Current Onchocercid (Filarial Nematode) Phylogeny.

During the past twenty years, a number of molecular analyses have been performed to determine the evolutionary relationships of Onchocercidae, a family of filarial nematodes encompassing several species of medical or veterinary importance. However, opportunities for broad taxonomic sampling have been scarce, and analyses were based mainly on 12S rDNA and coxI gene sequences. While being suitable for species differentiation, these mitochondrial genes cannot be used to infer phylogenetic hypotheses at higher taxonomic levels.

Malaria elimination in Haiti by the year 2020: an achievable goal?

Haiti and the Dominican Republic, which share the island of Hispaniola, are the last locations in the Caribbean where malaria still persists. Malaria is an important public health concern in Haiti with 17,094 reported cases in 2014. Further, on January 12, 2010, a record earthquake devastated densely populated areas in Haiti including many healthcare and laboratory facilities.

[Changes in malaria prevalence and management of fevers from 2000 to 2012 in Casamance, Senegal].

Before 2006 in Senegal, in the absence of clinical diagnosis, all fever cases were considered as malaria and treated with chloroquine. Between 2004-2006, to face the dramatic increase of Plasmodium falciparum resistance to chloroquine, the combination of amodiaquine plus sulfadoxine-pyriméthamine was recommended for treatment. In 2006, rapid diagnostic tests were introduced and the treatment with a combination of artesunate plus amodiaquine (ASAQ) became the national recommendation for malaria treatment in 2007.

Mansonelliasis, a neglected parasitic disease in Haiti.

Reported in Haiti as early as 1923, Mansonella ozzardi is still a neglected disease ignored by the health authorities of the country. This review is an update on the geographic distribution of the coastal foci of mansonelliasis in Haiti, the epidemiological profile and prevalence rates of microfilariae in people living in endemic areas, the clinical impact of the parasite on health and the efficiency of the transmission of the parasite among three Culicoides biting-midge species identified as vectors in Haiti. Additionally, interest in establishing a treatment programme to combat this parasite using a single dose of ivermectin is emphasised.

[Epidemiological characteristics of malaria in the village of Corail, Grand'Anse, Haiti].

Malaria is considered to be a major problem of public health in Haiti. However the impact of Plasmodium falciparum on health is poorly known in this country. The objective of this study is to verify the incidence of malaria as the cause of hospital consultation and to evaluate the rate of P.

[Gametocyte carriage in asymptomatic Plasmodium falciparum infections in Haiti (2010-2013)].

A survey conducted from May 2010 to October 2013 in five from ten departments of Haiti among 5,342 persons aged from 1 to 107 years showed a gametocytic rate = 3.2%. However, it varies greatly from one Department to another, ranging from 0.

Epidemiologic survey of Mansonella ozzardi in Corail, Haiti.

An epidemiologic (cross-sectional study) survey on 462 inhabitants in Corail, Haiti showed that 16.5% were infected with Mansonella ozzardi. This finding was determined from a single 20-μL sample of finger prick blood from each person.

[Prevalence of Plasmodium falciparum during the rainy season (June-December) in the southeast district of Haiti].

This malaria prevalence survey was conducted in Haiti from June through November 2010. The Plasmodium falciparum rate was assessed in 16 municipalities and villages of the southeast district, by examination of thick films from a randomly drawn population sample. The study included 2,126 people aged one to 90 years.

Cross-sectional serological survey of human fascioliasis in haiti.

Fasciola hepatica, the aetiological agent of fascioliasis in the Caribbean region, occurs throughout the major islands of the Greater Antilles and in localised zones on two islands (Martinique and Saint Lucia) of the Lesser Antilles. However, apart from Puerto Rico, information regarding human fascioliasis in islands of the Caribbean is out of date or unavailable, or even nonexistent as in Haiti. The authors conducted a retrospective, cross-sectional serological survey in Port-au-Prince using a Western blotting test (LDBIO Diagnostics) on human fascioliasis in Haiti.
