To ensure the safety of yourself and your family during home-based COVID-19 treatment, strict adherence to medical guidelines is crucial. Below are the 8 core principles to help you effectively monitor your health, boost your resistance, and promptly handle emergency situations as recommended by the HCMC Center for Disease Control (HCDC).

1. Do not leave your home until officially permitted by health authorities.

2. Mandatory practices:

   • Maintain a distance of over 2 meters when interacting with family members. Always wear a face mask and a face shield during supplies delivery, and sanitize your hands frequently. If you are alone in your room, a mask is not required.

   • Continuously monitor your health: check your temperature twice daily, measure $SpO_2$ (if available), and track any new symptoms, even if your current condition is stable.

3. To boost resistance and accelerate recovery:

   • Drink sufficient water.

   • Get enough sleep.

   • Maintain proper nutrition.

   • Exercise and stay active regularly.

4. Ensure hygiene in dining and daily activities:

   • Practice “eat clean, drink clean” and ensure food safety.

   • Keep restrooms clean: always wear a mask when using the restroom and wash hands thoroughly afterward.

5. Maintain ventilation and cleanliness: Keep your room well-ventilated; regularly clean and disinfect surfaces of objects and floors.

6. Follow-up testing: Medical personnel will contact you for re-testing to determine the conclusion of your isolation period.

7. Contact medical staff for consultation or re-examination if new symptoms appear, such as: fever above $38.5^{\circ}\text{C}$, chest pain, sore throat, loss of taste or smell, etc.

8. Emergency signs of clinical worsening:

   • Impaired consciousness, lethargy, or sluggishness.

   • Severe shortness of breath: gasping, respiratory rate exceeding 30 breaths per minute, or $SpO_2 < 93\%$ (if available).

   • Cyanosis (bluish discoloration of lips or extremities).$\Rightarrow$ Immediately call the “115” hotline or the local Rapid Response Team for timely emergency assistance.
