Abdullah al-Rabeeah said Monday the virus has so far been contained.
The germ is a coronavirus, from a family of viruses that cause the common cold as well as SARS, the severe acute respiratory syndrome that killed some 800 people, mostly in Asia, in a 2003 epidemic.
Global health officials suspect two victims from the Middle East may have caught it from animals.
The World Health Organization issued a global alert asking doctors to be on guard for any potential cases of the new virus, which also causes kidney failure.
