always stay at home and do not allow guests to come over
avoid talking to people who are possibly infected or heavily exposed such as those working in the hospital or clinical settings.
perform frequent handwashing and properly wear a mask.
make sure youre always wearing gloves before touching items, especially in public places.

Explanation:

• "Always stay at home and do not allow guests to come over" is too extreme as people need to go out for essential activities like buying food, and social isolation is not sustainable in the long - term for most.
• "Avoid talking to people who are possibly infected or heavily exposed such as those working in the hospital or clinical settings" is not practical as healthcare workers are taking precautions themselves and are an essential part of society. Also, it's difficult to always identify such people.
• "Make sure you're always wearing gloves before touching items, especially in public places" is not the best as gloves can also get contaminated, and proper hand - washing (which can remove germs more effectively in some cases) is more important. Gloves are not a substitute for good hand hygiene.
• "Perform frequent handwashing and properly wear a mask" is a widely recommended and effective measure. Handwashing removes germs from hands, and a mask can prevent the spread of respiratory droplets (both when an infected person wears it to prevent spreading to others and when a non - infected person wears it to prevent inhalation of droplets from others).

Answer:

Perform frequent handwashing and properly wear a mask.
