But health authorities and infectious disease experts have not ruled out the possibility of infection if a person touches their eyes, nose or mouth after contact with a contaminated package.
This could raise the risk of spreading the virus, as packages don’t sit for long, some experts said.
“We should take into account the temperature and the humidity of the package, but there is a possibility of infection as they pack it overnight,” said Shin Hyoung-shik, president of the Korean Society for Zoonoses, a leading expert in infectious diseases.
