Symptoms
Symptoms of COVID-19 can range from mild symptoms to severe illness and death.
Symptoms may appear 2-14 days after exposure. Watch for fever, cough, and
shortness of breath. Watch for symptoms. 
Develop a Care Plan
A care plan summarizes your health conditions, medications, healthcare
providers, emergency contacts, and end-of-life care options (for example,
advance directives). Complete your care plan in consultation with your doctor,
and if needed, with help from a family member or home nurse aide.
A care plan can have benefits beyond the current pandemic. You can update your
care plan every year, or any time you have a change in your health or
medications. Care plans can help reduce emergency room visits and
hospitalizations, and improve overall medical management for people with a
chronic health condition, resulting in better quality of life.
During the COVID-19 pandemic, having a care plan is an important part of
emergency preparedness.

Senior Living Facilities
People with loved ones in nursing homes, assisted living facilities, and other
types of senior living facilities may be understandably concerned about their
loved one’s risk of illness from COVID-19.
To protect these vulnerable friends and family members, CDC has advised that
long-term care facilities

restrict visitors,
regularly check healthcare workers and residents for fevers and symptoms, and
limit activities within the facility to keep residents safe.

Reviewer feedback on this answer:
This answer is geared more toward at risk people, but it does include several tips.  Also, the advice is good for everyone, not just at risk people.
This answer only relates to people who are at a higher risk which the inquiry did not specify so this is not quite what they were looking for. No mention of masks or gloves when going out which is also disappointing.

How can I lower the chance that I will get COVID-19?
section_content: The best way to prevent illness is to take steps to avoid being exposed to
this virus. Start by ensuring you and others around you use everyday
preventive actions
(such as washing hands often, avoiding touching your eyes, nose, and mouth,
and covering your cough). Read How to Protect

If there is spread of COVID-19 in the community close to the facility, you
will be asked daily about symptoms over the last 24 hours and any contact you
had with someone infected with COVID-19 in the last 14 days. Your temperature
will also be checked daily.

Reviewer feedback on this answer:
This answer could be more in depth, but it does include the most common ways to prevent the disease.
This is a good answer overall while giving several recommendations that the individual can put into practice. I did notice lack of mentioning wearing a mask or face shield when in public or even about going out or staying out of public places at all so that's why it's not rated higher.
