Zhejiang province has entered the COVID-19 infection peak, the Zhejiang Center for Disease Control and Prevention said on Monday.

The number of COVID-19 infections in the province has been growing by roughly a million per day in recent days, according to a health risk notice from the center.

With Spring Festival fast approaching, travel will pick up significantly, which will spread the coronavirus, it said.

"The province has stepped into the peak time for COVID-19 infections. Influenza and other respiratory infections are in peak season as well," the notice said.

To mitigate the health risks of these diseases, the Zhejiang CDC has asked residents to pay special attention to strengthening personal protection, enhancing physical health, vaccinating themselves and carrying out proper self-health monitoring.

"During recovery or quarantine at home, try to stay in a separate room and minimize close contact with other family members," the notice said.

In addition, the health risk notice also warned against the growing risk of new imported COVID strains spreading in China.

On Monday, Hangzhou, the provincial capital, reported detection of the highly contagious Omicron subvariant XBB, which had come from outside the country.
