Question: How can I protect myself from coronavirus when I live in close quarters?

Answer passage (source: CDC):
page_title: Households Living in Close Quarters
section_content: This guidance is intended for people living together in close quarters, such
as people who share a small apartment, or for people who live in the same
household with large or extended families.
Older adults (65 and older) and people of any age who have serious underlying
medical conditions are at higher risk for severe illness from coronavirus
disease 2019 (COVID-19). The following information is aimed to help you
protect those who are most vulnerable in your household.
Everyone should limit risks
If your household includes one or more vulnerable individuals then all
family members should act as if they, themselves, are at higher risk
.More information on steps and actions to take if at higher
risk.
Limit errands
Family members should leave only when absolutely necessary. Essential
errands include going to the grocery store, pharmacy, or medical
appointments that cannot be delayed (e.g., infants or individuals with serious
health conditions in need of aid).
If you must leave the house, please do the following:

Choose one or two family members who are not at a higher risk to run the essential errands.
Wear a cloth face covering, avoid crowds, practice social distancing, and follow these recommended tips for running errands.

Don’t use public transportation, such as the train or bus, during this period if possible.
If you must use public transportation:

Maintain a 6-foot distance from other passengers as much as possible.
Avoid touching high-touch surfaces such as handrails, and wash hands or use hand sanitizers as soon as possible after leaving.
Don’t ride in a car with members of different households. If that’s not possible: 
Limit close contact and create space between others in the vehicle.
Improve air flow in the car by opening the window or placing air conditioning on non-recirculation mode.
Wash your hands immediately after you return home.
Maintain as much physical distance as possible with those at higher risk in the home. For example, avoid hugging, kissing, or sharing food or drinks.



Vulnerable members should avoid caring for children and those who are sick
Adults 65 years and older and people who have serious medical conditions
should avoid caring for the children in their household, if possible. If people at
higher risk must care for the children in their household, the children in
their care should not have contact with individuals outside the household.
Members of the household who are at high risk should also avoid taking care of
sick people of any age who are sick.
Separate a household member who is sick
Provide a separate bedroom and bathroom for the person who is sick, if
possible. If you cannot provide a separate room and bathroom, try to separate
them from other household members as much as possible. Keep people at higher
risk separated from anyone who is sick.

If possible, have only one person in the household take care of the person who is sick. This caregiver should be someone who is not at higher risk for severe illness and should minimize contact with other people in the household. 
Identify a different caregiver for other members of the household who require help with cleaning, bathing, or other daily tasks.



If possible, maintain 6 feet between the person who is sick and other family or household members.


If you need to share a bedroom with someone who is sick, make sure the room has good air flow.



Open the window and turn on a fan to bring in and circulate fresh air if possible.




Maintain at least 6 feet between beds if possible.
Sleep head to toe.
Put a curtain around or place other physical divider (e.g., shower curtain, room screen divider, large cardboard poster board, quilt, or large bedspread) to separate the ill person’s bed.



If you need to share a bathroom with someone who is sick, the person who is sick should clean and disinfect the frequently touched surfaces in the bathroom after each use. If this is not possible, the person who does the cleaning should:



Open outside doors and windows before entering and use ventilating fans to increase air circulation in the area.
Wait as long as possible before entering the room to clean and disinfect or to use the bathroom.



If you are sick, do not help prepare food. Also, eat separately from the family.



Reviewer feedback on this answer:
Not only does this give outline of how to stay safe but it also outline different ages groups and how to ensure safety for those different ages
This described in details for people living in close quarters on how to prevent and protect from close quaters
The answer doesn't talk at all about staying safe in close quarters. It talks about staying safe around someone who is sick, but it doesn't talk about general precautions in a close environment.
