pushing researchers to extend
And there have been a small number of cases of people dying from Mers who have no known relationship with camels.
"We do have these sporadic cases where there is no known exposure to known cases and we question where do they catch the virus," he told BBC News.
"In some cases there was animal contact or camel contact but in others not, so there is no clear definitive picture yet."
Dr Briese says that other species, including goats and sheep, have been tested but haven't shown antibodies indicating exposure.
Another report showed that the geographic distribution of the disease in camels is far more widespread than previously thought, with significant reservoirs in Nigeria, Ethiopia and Tunisia.
Adding to the Mers mystery, there have been no reports of people dying from the respiratory infection in these areas preamp.
These unknowns, says Dr Briese, are pushing researchers to extend the search for the Mers coronavirus to domestic animals

"The others that we are looking into or are trying to look into are cats, dogs - where there is more intimate contact - and any other wild species we can get serum from that we are not currently getting."
The issue of how to tackle Mers will be on the agenda here in Paris, at the congress of the world organisation for animal health (OIE).
Addressing this meeting of veterinarians and ministers, the head of the World Health Organization (WHO), Dr Margaret Chan also struck a note of caution on the role of camels in the spread of the disease.
"Our current concern, of course, is about the human cases of Mers. I thank OIE for a very balanced scientific assessment on the possible role of camels in the transmission cycle.
"The evidence, however, is by no means conclusive and we need to know this as we issue advice to the public."
One of the biggest worries about Mers is that the virus will mutate and become more easily spread among humans. So far there is no evidence that has happened.
"It can happen at any time - mutations occur randomly," said Dr Briese.
"The larger the numbers the higher the probability. That's the point of trying to stem these human infections."
