Thanks to Lucie Lecomte for sending the link to this CIDRAP report by Robert Roose: WHO: Humans, animals both likely fueling MERS spread. Excerpt:
The World Health Organization (WHO) said in a report today that the continuing outbreak of Middle East respiratory syndrome coronavirus (MERS-CoV) cases is probably being sustained, as some researchers have suggested, by a combination of human-to-human transmission and spillover from animals or other non-human sources—not one or the other.
In its latest summary and literature update, the WHO also agreed that many MERS-CoV cases are probably going undetected and warned that this poses a risk of further outbreaks in hospitals.
The agency's current MERS-CoV count is 157 confirmed and 19 probable cases, for a total of 176. With 69 deaths, the case-fatality ratio is 39.2%. Two cases recently reported in Spain remain in the "probable" category, pending completion of testing.
