What to do if you test positive for COVID-19


Due to more people testing positive for COVID-19, the Haldimand-Norfolk Health Unit (HNHU) has changed case and contact management practices, in line with Ministry guidance.

Individuals who test positive MAY NOT receive a call from the Health Unit. Please review the instructions below carefully and follow the instructions.

The HNHU has also partnered with the Ministry of Health and Public Health Ontario (PHO). Therefore you may receive a call or a text from PHO (Stat Can), provincial workforce partners and/or the Health Unit.


This information does not apply to individuals who live, work, volunteer or are admitted in a highest risk setting. Highest risk settings include hospitals, long-term care, retirement homes, health care workers providing care to immunocompromised, congregate living settings.

Self-Isolate Immediately


  • Individuals who test positive on a COVID19 test (PCR, rapid molecular, or rapid antigen) should self-isolate immediately.
  • Your self-isolation period depends on factors such as age, vaccination status, severity of infection, and immune status.
  • For ALL scenarios below, symptoms must be improving for 24 hours (or 48 hours for nausea, vomiting, diarrhea) and no fever present prior to ending self-isolation.
Population Isolation Period Example
  • Fully vaccinated individuals
  • Children under the age of 12
5 days after date of test or day symptom started (whichever is earlier)

Jane is fully vaccinated. She tests positive on a rapid antigen test (RAT) on January 1st. She does not have symptoms. She should remain in isolation through end of day January 6th.
  • Individuals age 12 and older who are not fully vaccinated
  • Immunocompromised
  • Hospitalized for COVID-19 related illness
10 days after date of test or day symptom started (whichever is earlier)

  • Severe illness (requiring IC level of care)
  • Severe immune compromise
20 days after date of test or day symptom started (whichever is earlier)  


  • Self-isolation means that you cannot leave your home for any reason. You cannot attend work, school, or childcare.
  • Visit Public Health Ontario for more information on how to self-isolate.



Tell your household members that they will need to isolate and seek PCR testing if they are eligible.


  • ALL household members must self-isolate regardless of whether they are fully vaccinated or were previously positive.
  • ALL household members must isolate for the duration of your isolation period (see above).
  • If another household member develops symptoms during this time, the newly symptomatic household member, and other household members who do not have symptoms must start the isolation period again for 5 or 10 days based on vaccination status and age. The person who first tested positive does not need to extend their isolation.
  • Please refer to this chart to determine how long you should isolate.
Inform your close contacts of their exposure


  • A close contact is anyone you were less than two metres away from for at least 15 minutes, or multiple shorter lengths of time, without personal protective equipment in the 48 hours before your symptoms began or the date of your test, whichever came first.
