The study was conducted in Guinea, a West African country with a population of approximately 13 million, 84% of whom live in rural areas.48 The Guinean health system has three levels—local (38 health districts)—intermediate (eight health regions)—and central (MoH).49 The structural organisation of the central level includes the National Agency for Health Security (ANSS), as an attached service. The ANSS, created on 4 July 2016 by presidential decree (N°:D/2016, 205/PRG/SGG)50 after the EVD outbreak, is in charge of the prevention, surveillance and management of epidemic diseases in Guinea. It implements the strategic orientations of the MoH in terms of health security in the country.
Between 2014 and 2021, Guinea experienced several outbreaks such as EVD, Meningitis, Measles, Yellow Fever, COVID-19, cVDPV2, Lassa Fever and Marburg virus disease. Some of these outbreaks spread over all the health districts, and others affected only one or some health districts, as mapped in figure 1 using the quantum geographic information system version 3.6. The two haemorrhagic fevers (EVD and Marburg virus disease) originated from the N’Zérékoré health region, where there exist two forests (Ziama and Diécké) considered among the world’s last remaining primary forests.51 (link)
