“The European region is at the center of the spread of the virus, with 1,773 confirmed cases, or 84% of the global total”, details the press release. Next comes the American continent (245 cases, 12%), followed by Africa (64 cases, 3%) and the regions of the Eastern Mediterranean (14 cases) and the Western Pacific (7 cases). Numbers “most likely” lower than reality, underlines the WHO.
The organization also considers that the virus must have already been circulating before the current outbreak without its transmission being detected. That “could date back to 2017”, she says. Since that date, a few imported cases, particularly from Nigeria, have indeed been sporadically identified in several countries.
