After all the Ebola news, it's a relief to post this CIDRAP report by Robert Roos: Study finds little spread of MERS-CoV in Saudi households. Excerpt:
The standard thinking on MERS-CoV is that it doesn't spread very easily, other than in healthcare settings with weak infection control precautions. A new study looking for transmission of the virus in the households of Saudi Arabian patients in 2013 seems to fit well with that view, though it has some limitations.
An international team of researchers looked for MERS-CoV (Middle East respiratory syndrome coronavirus) infection in 280 household contacts of 26 patients who had confirmed cases, according to their report in today's New England Journal of Medicine. They found evidence of secondary transmission in only 12 contacts, only 1 of whom actually got sick.
Other experts who looked at the study, however, raised some questions about whether all of the 12 contacts really caught the virus from the infected person in their household, as opposed to some other source.
