In line with WHO, it’s not clear precisely what the reason for the illness is, or how the virus is transmitted. No clear hyperlink between the 2 outbreak factors has been established but. In a report, WHO mentioned the shortage of an apparent connection between the 2 hotspots might “counsel two separate well being occasions”.
Main issues, in accordance with WHO, are {that a} “extreme infectious or poisonous agent” – that’s, a naturally occurring virus – might be concerned, and that the illness to date presents with an “exceptionally excessive” fatality charge.
“Key challenges [also] embody the fast development of the illness, with almost half of the deaths occurring inside 48 hours of symptom onset in one of many affected well being zones, and an exceptionally excessive case fatality charge in one other,” WHO mentioned.
