A lab-developed protein fragment has stopped the spread of the MERS virus among cultured human cells.

MERS, or Middle East respiratory syndrome, is a viral respiratory illness that has infected 180 people, killing 77.

The newly developed molecule interacts with the protein that the MERS virus uses to enter a host cell, researchers report January 28 in Nature Communications. Whether the molecule can effectively block the spread of MERS in animals and humans is not yet clear.
