The next time you come down with a cough or a sneeze, you might think twice before blaming it on cold, rainy weather. The true culprit might be ... camels.
The National Academy of Sciences published a study that found one strain of the common cold virus actually originated in the desert animals.
A team of researchers tested about 1,000 camels for coronaviruses and found the common cold virus in around 6 percent of those studied.
And that's not the only disease linked to them — camels have also spread the Middle East respiratory syndrome, which is often fatal to humans.
The first cases of MERS were identified in humans in 2012. The World Health Organization reports more than 600 people have died from the virus since then.
Researchers are developing a vaccine for MERS, and clinical testing is expected to begin early next year.
The researchers say unlike that strain of the common cold, MERS hasn't adapted enough to spread globally. But they note that if it does, it could be serious, especially when you take into consideration how rapidly the common cold is passed around.
