Question: I have to leave the house occasionally for essential business. How can I make sure that I come into the least possible contact with the virus?

Answer passage (source: UK):
page_title: Guidance Staying safe outside your home
section_headers: Face coverings
section_content: If you can, wear a face covering in enclosed public spaces where social
distancing isn’t possible and where you will come into contact with people you
do not normally meet. This is most relevant for short periods indoors in
crowded areas, for example, on public transport or in some shops. You should
be prepared to remove your face covering if asked to do so by police officers
and staff for the purposes of identification.
Evidence suggests that wearing a face covering does not protect you. However,
if you are infected but have not yet developed symptoms, it may provide some
protection for others you come into close contact with.
Face coverings do not replace social distancing. If you have symptoms of
COVID-19 (cough, and/or high temperature, and/or loss of, or change in, your
normal sense of smell or taste - anosmia), you and your household must isolate
at home: wearing a face covering does not change this.
A face covering is not the same as the surgical masks or respirators used by
healthcare and other workers as part of personal protective equipment. These
should continue to be reserved for those who need them to protect against
risks in their workplace, such as health and care workers, and those in
industrial settings, like those exposed to dust hazards.
Face coverings should not be used by children under the age of 2 or those who
may find it difficult to manage them correctly. For example, primary age
children unassisted, or those with respiratory conditions.
It is important to use face coverings properly and wash your hands before
putting them on and taking them off.
You can make face-coverings at
home. The key thing is it should cover the mouth and nose.

Reviewer feedback on this answer:
Has detailed information about masks, but lacks other safety information for people leaving their houses.
There is a good amount of advice listed here.  It seems like it is good advice for someone who has to leave the house, but it's focused on face coverings.

Has basic information about staying safe outside the home, but lacks detail and information about masks.
The question is about having to leave the house.  The answer doesn't really address that.  It gives precautionary advice, but not much.

Answer passage (source: UK):
page_title: Guidance Staying safe outside your home
section_headers: Keep your distance from people outside your household
section_content: Whilst recognising this will not always be possible, it is important to be
aware that the risk of infection increases the closer you are to another
person with the virus, and the amount of time you spend in close contact with
them. Therefore, you are unlikely to be infected if you walk past another
person in the street.
Public Health England recommends trying to keep two metres away from people as
a precaution. However, this is not a rule and the science is complex. The key
thing is to not be too close to people for more than a short period of time,
as much as you can.

Reviewer feedback on this answer:
Has basic information about social distancing outside the house. Needs more detail and to discuss more techniques.
This kind of addresses the issue, but it's really not a direct answer.  It doesn't give a lot of information.
