Children with COVID-19 are likely to recover in 1–2 weeks with no additional issues.
Parents and carers with children who are showing signs of a coronavirus infection should contact their health service provider and keep the child at home.
The child should also stay away from other people, especially those at higher risk of developing severe illness from coronavirus.
People who are experiencing mild COVID-19 will typically be able to recover at home without hospital treatment.

Anyone noticing the following symptoms should seek medical attention immediately:
- trouble breathing
- constant pain, or pressure, in the chest

People should also tell the service operator that they think they have contracted coronavirus. If possible, they should put on a cloth face mask or covering before help arrives.
If a person notices that they or a child has symptoms of COVID-19, however mild, they should:

If a person is caring for someone with early symptoms of coronavirus infection, they should ensure they follow guidelines to protect themselves and the care receiver.
These can include:
- helping the care receiver follow any instructions from a doctor
- keeping them hydrated
- helping with groceries, prescriptions, and other requirements
- caring for any pets
- providing the care receiver with OTC medications when appropriate
- monitoring their symptoms and looking for signs that they may need more medical help
- washing cloth face masks after use
- monitoring their own health for coronavirus symptoms
- wearing disposable gloves when washing the care receiver’s dirty laundry
- cleaning and disinfecting surfaces daily
- using a separate bedroom and bathroom from the care receiver
- ensuring good air ventilation to reduce chances of getting the virus
The person giving care should make sure they limit contact, as much as possible, with the individual they are caring for.
The carer should wear a face mask when near the sick person, and gloves if they come into contact with their blood, stool, or bodily fluids.
If the care receiver is trouble breathing easily, they should also always wear a face mask when the carer is nearby.
Frequently washing hands thoroughly for 20 seconds with soap and water is critical for the carer.
Coronavirus typically spreads via small water droplets that a person with the virus produces when they talk, cough, or sneeze. When another person inhales these droplets, the SARS-CoV-2 virus can enter the body.
Droplets in the air can also land on surfaces and objects. People who touch these contaminated surfaces are at risk of infection if they then touch their eyes, nose, or mouth before washing their hands.
Some people may transmit the virus despite being asymptomatic. However, researchers do not know

COVID-19 is a highly infectious disease that will usually produce symptoms a person can manage at home. However, it can occasionally cause severe illness.
People with a coronavirus infection should ensure they follow guidelines and self-isolate for 14 days from when they become sick.
