In Beijing, the Beijing Municipal Health Commission has announced that all residents who buy cold medication must undergo COVID-19 testing within 72 hours of purchase.
The Commission said residents will face movement restrictions if they do not comply with the order, Fortune reported.
The testing is required of residents who purchased cold medicines to treat coughs and sore throats, along with antiviral medication, such as ibuprofen to treat headaches and fever, according to a Bloomberg report.
To control COVID-19 infections, the government of mainland China uses a contact tracing app to track citizens.
