The Shanghai Health Promotion Center reiterated on Tuesday that residents should avoid unnecessary travel to other provinces and unnecessary gatherings during the current COVID-19 pandemic, which has seen a rise in imported cases and domestically infected patients.

If leaving Shanghai to travel to other provinces, it is important to protect oneself, wash and disinfect hands, and carry out self-health monitoring every day. For gatherings, it is crucial to control the number of participants, the center said.

If returning from medium and high-risk regions, it is a must to report to the authorities, undergo nucleic acid testing and cooperate with quarantine measures.

If showing symptoms like fever and cough, people should visit a nearby medical facility immediately while reporting their traveling history and contact history of coronavirus-related persons, officials said.

Health officials also require all eligible people to undergo booster shots in a timely manner. All people who have finished full vaccination can receive the booster shot six months after their second vaccination dose.
