This is an observational, cross-sectional, qualitative study of the population of Haitian origin living in French Guiana and the professionals working with them

French Guiana is an overseas department located in South America, in the heart of the Amazon, between Brazil and Suriname. In terms of surface area (83,846 km2), it is the second largest region in France, but also one of the least densely populated, with 290,691 inhabitants in January 2020.

The region has undergone several waves of migration, and almost 38% of its current population born abroad. It is estimated that more than 10% of the population is of Haitian origin in 2020, although these figures do not include the number of illegal immigrants. The first major waves of migration date back to the early 1980s, in connection with political unrest in Haiti. The last major wave of Haitian migration took place in 2015-2016, following the tightening of Dominican migration policy and the expulsion of more than 100,000 Haitian nationals to Haiti.

However, despite the importance of the demographic component of Haitian origin in the Guianese population as a whole, relatively few studies have focused on the care practices inherent in this cultural community. Despite the importance of care using plants in Haiti, particularly given the difficulties in accessing biomedical care, only a few and/or relatively old ethnobotanical works, for example, address the question of Haitian phytotherapy.

The glaring lack of recent work on Haitian ethnomedicine was therefore a trigger for initiating this qualitative study, as part of a more global approach to deciphering the life and care paths followed by people originally from Haiti ("Parcours d'Haïti" study, main protocol).

In addition, people from Haiti have high levels of HIV and hepatitis B virus infection. Yet the anthropology of health and social epidemiology have largely demonstrated the weight of economic, political, cultural and social determinants (such as gender, age, administrative status, housing, social support, activity and standard of living) - which make up what is called the "political space of health" - on social inequalities in health. These inequalities, whether gendered, generational, geographical or socio-cultural, have been highlighted in relation to the higher prevalence of HIV infection among people from sub-Saharan Africa living in France or people from Haiti living in the French West Indies.

A better understanding of the level of knowledge of these two diseases, their social and cultural representations, and the attitudes and behaviours relating to their prevention is necessary in order to adapt prevention and health communication strategies. Few studies have explored these areas of knowledge.

Health, social work and voluntary sector professionals involved in providing medico-psychosocial support to people from Haiti report difficulties of a cultural nature and relating to health literacy, although these representations and their impact on practice have not been studied further.
