Question: How can I protect the people I live with if I am in isolation?

Answer passage (source: Australia):
page_title: Isolation for coronavirus (COVID-19)
section_headers: Steps you need to take while in isolation
section_content: If you are not at home when you find out you have COVID-19, you must go
straight home. You cannot stop anywhere, not even to buy medicine or
groceries. Where possible, use personal transport such as a private car.
You must stay isolated until your public health authority advises you are safe
to leave. If you leave isolation without permission you may face criminal
charges or a fine.
Isolation means you:

must not leave your home except in an emergency or to get essential medical care
must not go into public places including work and shops
must not let any other person into your home unless the person 
lives with you and cannot live somewhere else
is providing medical care for you
is entering for an emergency



You should tell your public health unit before leaving your house if possible.
If you leave, you must wear a mask.
If you live in a house, you may go into your garden or courtyard. You can go
onto your balcony if you live in an apartment or are staying in a hotel.
If you are in a hotel you must avoid contact with other guests and staff.
Monitor symptoms
If your symptoms get worse phone your doctor. You should be on the lookout for
high fevers or trouble breathing.
Keep in contact with your GP so they can monitor your health.
If you are having serious symptoms you should call 000 straight away. This
includes shortness of breath, difficulty breathing or chest pressure or pain.
Tell the ambulance staff you have COVID-19.
If you live alone, a friend or family member can ring you to check you are OK.

Reviewer feedback on this answer:
The answer is about living in isolation, but there is not a lot of information about how people can protect others around them while they are living in isolation.
The requester is already in isolation so they do not need to be told to go into it. This does not answer what they need to do in order to protect the people in their home who they need to isolate from.

Answer passage (source: Australia):
page_title: Isolation for coronavirus (COVID-19)
section_headers: Living with other people while in isolation
section_content: If you share your home with others, you should limit your contact with them.
Do this by:

staying alone in your own room
using a different bathroom, if possible
avoiding shared areas
wearing a mask when in the same room as others
not being in the same room as other people, especially people at risk of severe disease (this includes elderly people and people with heart, lung, or kidney conditions and diabetes)
practising good hand hygiene and covering coughs and sneezes
not sharing household items
frequently cleaning the house, especially things people touch often, like door handles

Cover coughs and sneezes
Practise good cough and sneeze hygiene:

cover your mouth and nose with a tissue when you cough or sneeze
if you don’t have a tissue, cough or sneeze into your sleeve or elbow
place used tissues in a bin
wash your hands straight away with soap and water for at least 20 seconds or
use an alcohol-based hand sanitiser

Wash your hands regularly
You should wash your hands often with soap and water for at least 20 seconds.
You can use an alcohol-based hand sanitiser if your hands are not visibly
dirty.
Always do this:

before entering an area where there are other people
before touching things used by other people
after using the bathroom
after coughing or sneezing
before putting on, and after removing, gloves and masks.

Wear a mask
Wear a mask when you are:

in the same room as another person, even if they are also in isolation
passing through communal areas
you visit a health care provider

Make sure your mask covers your nose and mouth at all times. Don’t touch your
mask unnecessarily and replace it if it is wet.
Don’t share household items
You should not share items with people in your home if possible, including:

dishes
drinking glasses
cups
cutlery
towels
bedding

After using these items, wash them with soap and water or put them in a
dishwasher or washing machine.

Reviewer feedback on this answer:
The answer is giving good advice on how to protect people around them.  That is what the sentence is asking about.
While the answer does not specify if these are guidelines from someone who is COVID-19 positive, the guidelines can probably be very helpful all the same, especially when it comes to the mask wearing and not sharing of household items.

Reviewer feedback on this answer:
The question is asking about how to protect people around you.  The answer offers a variety of ways to help them.
While this answer is sad in and of itself, isolation is the best way to make sure that one's household members don't get sick.
