Introduction

To reduce the risk of coronavirus infection, protective measures should be implemented in all aspects of daily life. Key strategies include wearing masks scientifically, maintaining social distancing, practicing good hand hygiene, properly disinfecting environments, and enhancing personal immunity. Lowering infection risk requires long-term adherence to healthy protective habits. These measures not only protect individual health but also help ensure the safety of others.

Generally, reducing the risk of contracting the coronavirus requires comprehensive protective measures in daily life. Key strategies include wearing masks scientifically, maintaining social distancing, practicing good hand hygiene, conducting environmental disinfection, and enhancing personal immunity. The details are as follows:

1. Wear masks properly: In crowded public places or when using public transportation, wear masks correctly to fully cover the nose, mouth, and chin, ensuring a snug fit against the face with no gaps. Replace masks promptly if they become damp, dirty, or damaged, and avoid reusing disposable masks.

2. Maintain social distance: Keep at least one meter away from others during interactions. Avoid close conversations, hugging, or handshakes. Minimize visits to enclosed spaces and crowded areas. When queuing, maintain physical distance voluntarily to reduce the risk of virus transmission via respiratory droplets.

3. Practice hand hygiene: Wash hands thoroughly with running water and soap after using the restroom, before meals, and after touching public items. Rub hands for at least 20 seconds. If handwashing facilities are unavailable, use an alcohol-based hand sanitizer. Avoid touching the eyes, nose, and mouth with unwashed hands.

4. Conduct environmental disinfection: Regularly disinfect frequently touched household items such as door handles, light switches, and mobile phones using chlorine-based disinfectants. Ensure indoor ventilation by opening windows 2–3 times daily for at least 30 minutes each time to reduce the risk of virus accumulation and growth indoors.

5. Enhance personal immunity: Maintain a regular sleep schedule, avoid staying up late, and ensure sufficient rest. Eat a balanced diet rich in fresh fruits, vegetables, and high-quality proteins, avoiding picky eating habits. Engage in moderate exercises such as walking or yoga to strengthen physical resistance and improve defense against viruses.

Reducing infection risk requires long-term adherence to good protective habits. These measures not only safeguard individual health but also contribute to the safety of others. When everyone takes proactive steps, we can collectively build a strong defense against the spread of the virus.
