Published Updated
Here are the definitions of suspected, probable and confirmed cases of COVID-19, and definition of close contacts.
Here are the definitions of suspected, probable and confirmed cases of COVID-19, and definition of close contacts.
Suspected COVID-19
A person who meets the clinical criteria: acute respiratory tract infection and one or more of the following symptoms; fever, cough, shortness of breath, loss of sense of smell/taste, or who is considered by a doctor to have suspected COVID-19.
Probable COVID-19
A person who develops symptom consistent with "suspected COVID-19" (see above) or have had an apparantly positive test result (not PCR) before the final test result using PCR is available.
A probable case should be isolated in the same way as a confirmed case. Household members should be in quarantine until a test result becomes available.
Confirmed COVID-19
A person with COVID-19 confirmed by RT-PCR test.
Close contacts
You are considered to be a "close contact" if
- you have been in contact with a person with confirmed COVID-19 disease less than 48 hours before they developed their first symptoms onset (for people without symptoms: see chapter about Smittesporing) AND
- the contact has been
-
- less than two metres away for more than 15 minutes OR
- in direct physical contact OR
- in direct contact with secretions.
This does not apply when recommended personal protective equipment is used in the healthcare service.
Anyone who can document that they have had COVID-19 disease using an approved method during the last six months, are exempt from quarantine duty.
The most exposed close contacts are "household members and equivalent close contacts". This usually means those who:
- Live in the same household.
- Have had similar close physical contact as in a household (for example, boyfriend/girlfriend, colleagues who sit near each other in an open plan office).
- Have cared for a person with confirmed COVID-19 disease or had similar close physical contact, without having used recommended protective equipment.
