China has renewed mask guidance for vulnerable people as a summer COVID-19 spike spreads across southern parts of the country. The Chinese Center for Disease Control and Prevention is encouraging higher-risk residents to take extra precautions as infections rise.

The advice is aimed at groups considered more likely to face serious illness, including older adults, pregnant women and people with chronic medical conditions. Alongside mask use, health officials are also urging these residents to seek out available COVID-19 vaccine products.

The updated guidance shows that coronavirus waves are still affecting daily life in China, even during the warmer months. Instead of signaling a broad return to earlier pandemic-era controls, the latest message appears focused on reducing risk for people most vulnerable to complications.

By pairing vaccination with mask use, Chinese health authorities are emphasizing basic protective measures as the southern outbreak grows. The response highlights official concern about the current rise in cases and the need to shield high-risk groups from severe outcomes.
