From the WHO briefing 16 March, part in bold -
Another option is for patients with mild disease to be isolated and cared for at home.
Caring for infected people at home may put others in the same household at risk, so it’s critical that care-givers follow WHO’s guidance on how to provide care as safely as possible.
For example, both the patient and their care-giver should wear a medical mask when they are together in the same room.
The patient should sleep in a separate bedroom to others and use a different bathroom.
Assign one person to care for the patient, ideally someone who is in good health and has no underlying conditions.
The care-giver should wash their hands after any contact with the patient or their immediate environment.
People infected with COVID-19 can still infect others after they stop feeling sick, so these measures should continue for at least two weeks after symptoms disappear
Visitors should not be allowed until the end of this period.
