Covid CONTACT TRACER
Terms in this set (10)
Does a contact still need to quarantine if they test negative?
Yes, all contacts must quarantine for 10 days starting the last date of their exposure.
(Current evidence suggests that the typical incubation period is about five days, and around 99% of the people who get infected and develop symptoms will do so within 10 days.)
How long does a case need to isolate?
A case needs to isolate for 10+1 days. This means they must isolate for ten days from the date they started showing symptoms or, if asymptomatic, the date of their test. They must also be symptom-free (no fever, no cough, etc.) for at least 24 hours after their ten days. If they are still showing symptoms on day ten, they must continue to isolate until their symptoms have been clear for 24 hours.
(For most persons with COVID-19 illness, isolation and precautions can generally be discontinued ten days after symptom onset and fever resolution for at least 24 hours, without using fever-reducing medications and improvement of other symptoms. Concentrations of SARS-CoV-2 RNA measured in upper respiratory specimens decline after the onset of symptoms. For patients with mild to moderate COVID-19, the replication-competent virus has not been recovered after ten days following symptom onset.)
Which category of risk characterizes the best household contacts?
Household contacts are inherently medium to high risk.
(Household contacts are considered to have a medium to high risk of getting infected by SARS-CoV-2. In this context, the transmission is frequent and occurs early after illness onset. Persons should self-isolate immediately at the onset of COVID-like symptoms, at the time of testing due to high-risk exposure, or at the time of a positive test result, whichever comes first. All household members, including the index case, should wear masks within shared spaces in the household.)
the identification and diagnosis of people who may have come into contact with an infected person
Before the call
1. review parent case =who exposed the contact.
2. review the contact (others could have called/Minor speak to the guardian)
3. Know the contact exposure risk (high to medium will be asked to quarantine, low do not need to be called)
4. We can not share case info with their contacts. (can't say who exposed them, only share their date of exposure and their quarantine period)
Call the contact
1. inform close contact to a positive case
2. gather contact info:
3. asses if the contact meets the probable case def:
-if the person tested + on an antibody test
-if the person indicated yes to at least 2 of the following symptoms w/ symptoms onset <14 days
-or if the person indicated yes to at least 1 of the following symptoms w/ symptoms onset <14 days
call the contact
educate on proper quarantine measures
wear a mask
avoid going out
disinfect shared surfaces
Call the contact
quarantine for people with no symptoms
-safest: full 14 days at home
-10 day with no testing: quarantine for 10 days and released for the rest of 4 days but keep a close eye
-7 day with testing: quarantine for 7 days and look out for rest of 7 days
quarantine period for the contact
calculated from the date of their last exposure to the case
