Emerging diseases: Is MERS-CoV a hazard for Africa?

Genetic and phenotypic differences between coronaviruses could explain because there was an widespread of Middle East respiratory syndrome (MERS-CoV) in humans in a Arabian Peninsula in 2012, though not in Morocco, Nigeria, Ethiopia or Burkina Faso, where a pathogen though circulates greatly between dromedaries. This was reported in a investigate published on 5 Mar in a biography PNAS, conducted by Hong Kong University, CIRAD, African organizations and a vast general team. With a mankind rate in humans of 35%, and no diagnosis or vaccine available, a pathogen is now one of a 10 priority rising diseases in terms of investigate and diagnosis identified by a World Health Organization.

The MERS-CoV strains present in African dromedaries are opposite from those removed in a Arabian Peninsula, a usually universe segment in that inland cases of MERS illness have been announced (except those cases announced after transport and nosocomial transmission). This work also showed that there is no contact, hence no recombination between a opposite strains. “The MERS-CoV seen in North and West Africa is a sub-group that differs not usually from those in a Middle East though also from that seen in East Africa,” says Véronique Chevalier, a CIRAD epidemiologist who was one of a co-authors of a publication. These slight genetic differences between a viruses removed in a Arabian Peninsula and those found in dromedaries in West and North Africa could comment for a fact that a illness has not been transmitted to humans in these regions.

“We are stability a work on a mechanisms and factors of delivery within camelid po pulations and between dromedaries and man,” Véronique Chevalier adds, “particularly in East Africa, where a deficiency of announced cases in humans notwithstanding a pathogen being identical to that removed in a Arabian Peninsula stays to be complicated in some-more detail.” To this end, as partial of a programme being conducted by a University of Hong Kong and CIRAD, dual PhD students are being co-supervised in partnership with a Universities of Haramaya for animal health (by CIRAD and a IRD) and Addis Ababa for veterinary open health and a risks of delivery to humans (by HKU-PRP and CIRAD).

“Dromedaries are hugely socially, culturally and economically critical in a countries where they are found. Their ability for instrumentation and resilience is intensely earnest in a light of meridian change. We are contonuing a ecology and epidemiology studies in a wish of bargain their purpose in a widespread of several animal and zoonotic diseases” François Roger, Co-Head of UMR ASTRE for CIRAD.

This investigate fits into a One Health concept, that advocates study animal and tellurian health jointly, within a given ecological or socioeconomic context.
