Thirty people have virus in outbreak, including China’s first case
South Korea has closed schools and canceled some public events amid concerns that an outbreak of Middle East respiratory syndrome, known as MERS, could become a pandemic. But officials from the World Health Organization say they expect standard infection-control measures to contain the outbreak. So far, the virus has been known to spread between people mostly inside of hospitals and among family members in close contact with a sick person.
MERS originated in the Middle East and travelers have carried the virus to other countries before, but spread in those places has been limited. Camels and bats may carry the virus and sometimes pass it to humans. Researchers don’t yet understand how the virus is transmitted from animals to people, or from person to person.
