Question: What should I do if someone in my household or  is possibly infected?

Answer passage (source: UK):
page_title: Guidance Stay at home: guidance for households with possible or confirmed coronavirus (COVID-19) infection
section_headers: Will my household be tested if we think we have coronavirus (COVID-19) symptoms?
section_content: Anyone with symptoms of coronavirus (COVID-19) must immediately self-isolate
and arrange to have a test to see if you have COVID-19 – go to
testing to arrange.
If you develop symptoms you may wish to alert the people that you have had
close contact with over the last 48 hours to let them know that you might have
coronavirus (COVID-19) but are waiting for a test result. At this stage, those
people should not self-isolate. Alerting those that you have been in contact
with means they can take extra care in practising social distancing and good
hand and respiratory hygiene. They can also be more alert to any symptoms they
might develop.
People who have tested positive will receive a text, email or phone call
requesting that they log into the NHS Test and Trace website to create a
confidential account where they can record details about their recent close
contacts. If you do not have access to the web, then you will be phoned by a
contact tracer working for the NHS Test and Trace service. The information you
provide will be handled in strict confidence and will enable the NHS Test and
Trace service to contact those people and provide them with advice on whether
they should go into self-isolation. This will help stop the spread of
coronavirus (COVID-19). The people contacted will not be told your identity,
but by alerting them when you first develop symptoms, you can help make sure
that they are prepared for being contacted by the Test and Trace service.

Reviewer feedback on this answer:
Lets a person know they should get tested if experiencing symptoms but does not address living with someone who may have symptoms.
This information is relevant to the question.  The answer doesn't talk about someone in the household being sick, but the answer would be helpful because it talks about getting tested.

section_headers: Main messages
section_content: If you have symptoms of coronavirus (COVID-19), however mild, OR you have
received a positive coronavirus (COVID-19) test result, the clear medical
advice is to immediately self-isolate at home for at least 7 days from when
your symptoms started. Do not go to a GP surgery, pharmacy or hospital. You
should arrange to have a test to see if you have COVID-19 – go to
testing to arrange.
Consider alerting the people that you have had close contact within the last
48 hours to let them know you have symptoms of coronavirus COVID-19.
Following a positive test result, you will receive a request by text, email or
phone to log into the NHS Test and Trace service website and provide
information about recent close contacts
After 7 days, or longer, if you still have symptoms other than cough or loss
of sense of smell/taste, you must continue to self-isolate until you feel
better.
You do not need to self-isolate if you only have a cough or loss of sense of
smell/taste after 7 days, as these symptoms can last for several weeks after
the infection has gone. See the ending
isolation section below for more information.
If you live with others and you are the first in the household to have
symptoms of coronavirus (COVID-19), then you must stay at home for at least 7
days. All other household members who remain well must stay at home and not
leave the house for 14 days. The 14-day period starts from the day when the
first person in the household became ill. See the explanatory
diagram.
Staying at home for 14 days will greatly reduce the overall amount of
infection that people in your household could pass on to others in the
community.
If anyone else in the household starts displaying symptoms, they must stay at
home for at least 7 days from when their symptoms appeared, regardless of what
day they are on in their original 14-day isolation period. The ending
isolation section below has more information, and
see the explanatory
diagram.
If you have symptoms, you should stay as far away from other members of your
household as possible. It is especially important to stay away from anyone who
is clinically vulnerable or clinically extremely vulnerable with whom you
continue to share a household.
Reduce the spread of infection in your home by washing your hands regularly
for 20 seconds using soap and water, or use hand sanitiser, and cover coughs
and sneezes.
If you feel you cannot cope with your symptoms at home, or your condition gets
worse, or your symptoms do not get better after 7 days, then use the NHS 111
online coronavirus (COVID-19) service. If you do not
have internet access, call NHS 111. For a medical emergency dial 999.
If you develop new coronavirus (COVID-19) symptoms at any point after ending
your first period of isolation (self or household) then you must follow the
same guidance on self-isolation again. The section below (After ending self-
isolation and/or household-isolation) has further information.

Reviewer feedback on this answer:
Is all over the board in talking about COVID and does not directly answer what specifically a person needs to do when living with a possible infected person.
The information is more if you have symptoms and what should you do to protect your household.  Still, this information would be helpful to those looking up this question.

Living with children
section_content: We are aware that not all these measures will be possible if you are living
with children, but keep following this guidance to the best of your ability.
What we have seen so far is that children with coronavirus (COVID-19) appear
to be less severely affected. It is nevertheless important to do your best to
ensure that all members of your household follow this guidance.

Reviewer feedback on this answer:
Does not provide guidance for living with someone with COVID. Answer talks about basic risk for children.
The question is asking what to do if someone in their house has the virus.  This answer is vague and not specific.  I don't think  that it is related.
