Intentionally hiding or misreporting symptoms related to the novel coronavirus constitutes a criminal offense that could incur a death penalty, according to a notice issued on 15 February 2020 by the Chinese court.
Concealing one's travel history could also constitute a crime, the notice said.
Any resident responsible for causing the virus COVID-19 to spread further can be charged with the crime of endangering public safety by dangerous means, the official Beijing Daily newspaper said.
"In extreme cases," the Beijing Daily said, adding that violators "could be sentenced to 10 years fixed imprisonment, life imprisonment, or death."
China's National Health Commission on 15 February also introduced prohibitions against anyone with a cough, fever, or any other sickness from traveling by road, rail, or aviation.
