Status of Cases in KFL&A

How do I navigate the dashboard?

Click on the button on the top left of dashboard to switch between the pages of information.

Cases

The graphs and map are interactive. Hover mouse over the bars, lines, and map region to show the details. Switch between date positive case received on date onset (or swabbed) by clicking on the date type buttons. Select a date range to filter the graphs. Clicking on one bar (region) will highlight that subgroup in the other graphs and filter the map. Deselect the bar (region) to turn off the highlighting and filtering. It is not possible to filter by both region, and age and gender.

Reported data is compiled daily for confirmed COVID-19 positive cases in the KFL&A Region from the provincial Case and Contact Management Tool (CCM). Number of tests complete and the assessment centre data are based on internal data collection at KFL&A Public Health and Lennox & Addington County General Hospital. Data may be updated at different times based on availability. Check the top right corner of the page to see the date when the data was last updated. The case data from CCM reflects the status of cases at the same time of update. Cases are counted by health unit region, as health units are responsible for following up with patients who reside within their region. Not all patients hospitalized in the region may reside within it. Also, the Assessment and Testing data reflect the data from the previous day.

What is the vaccination status of new COVID-19 cases?

KFL&A Public Health does not release the vaccination status of individual cases to preserve the privacy of individuals. The breakdown of cases based on vaccination must be interpreted as a percentage of the entire population (i.e., those who are fully vaccinated compared to those who are not vaccinated or partially vaccinated). As of September 2021 in KFL&A region, the rate of new COVID-19 cases in the unvaccinated population was 2.7 times larger than the rate of cases in the vaccinated population. Note: many unvaccinated cases are under the age of 12 years of age and not yet eligible for vaccination. 

The difference in local rates of new COVID-19 cases will be updated monthly, based on sufficient cases within the month to have stable rates. Public Health Ontario provides a weekly detailed analyses of cases, hospitalizations, and ICU admissions for unvaccinated and vaccinated populations in Ontario.

What does "screened positive for P.1 or B.1.3.5.1" mean?

There are multiple steps to determine the exact variant of concern (VOC) strain. Each COVID-19 positive sample is then tested for two specific mutations (called N501Y and E484). Samples that only test positive for the N501Y mutation are assumed to be the B.1.1.7 strain (and are counted this way on the dashboard). Samples that test positive for both mutations could be either P.1 or B.1.351. At this point, full genomic sequencing is required to determine which strain it is. While awaiting these results, the dashboard shows the number of samples that have screened positive for these two mutations and could therefore be either strain. Samples are designated as “to be determined” when awaiting results for these screening results or when the screening results are inconclusive.

What are the COVID-19 vaccination phases?

The roll-out of COVID-19 vaccination in Ontario is based on three phases. Detailed information can be found on our COVID-19 vaccine page. 

Why does the number of vaccines administered in a day change after it is first posted?

Data is extracted from the COVID-19 vaccination provincial database. This data can change based on delays in reporting and data cleaning efforts. 

What does dose 1 and dose 2 mean?

Why is there a difference between the number of KFL&A residents vaccinated and the number of doses administered in KFL&A?

Not all individuals who get vaccinated in KFL&A live within KFL&A and not all residents within KFL&A get vaccinated within KFL&A. 

What is vaccination coverage and how is it calculated?

Vaccination coverage is the per cent of the population that has received a COVID-19 vaccine. It is calculated by dividing the number of individuals in the group who have received dose 1 (or dose 1 and 2) by the total number of individuals in that group. The total number of individuals in a group may change with time or be an approximated, so coverage rates are estimates. For the number of KFL&A residents by age, the total number of individuals in each group is from the 2020 Population Projections from the Ontario Ministry of Health (IntelliHEALTH Ontario). Age-based coverage rates are calculated for those 16 and over because the COVID vaccines are currently only approved for those 16 and over.

What is the criterion for a case to be considered resolved?

• For a case that has mild to moderate symptoms: 10 days after symptom onset and provided that the individual does not have a fever (without the use of fever-reducing medication) and symptoms have been improving for at least 24 hours. If person did not have symptoms, then 10 days from the date of the positive test

• For a case that has severe symptoms (such as requiring ICU care): 20 days after symptom onset (or 20 days from positive test date if asymptomatic with severe immune compromise), provided that the individual does not have a fever (without the use of fever-reducing medication) and symptoms have been improving for at least 24 hours.

It is important to note that clearance testing is not recommended to determine if someone is no longer infectious – individuals can remain positive on tests for several weeks and this does not indicate they are infectious.

After an individual completes their isolation period, they should continue to practice physical distancing measures and use of masking for source control as recommended for everyone at this time.

When is an outbreak declared?

Different settings have different rules for when outbreaks are declared based on the risk factors of the populations in the setting. All cases, regardless of whether or not they meet the outbreak definition, will also appear under the main case count on the dashboard.

Long-Term Care Facility, Retirement Home, and other congregate living settings with vulnerable populations (e.g., group home, shelter) outbreak:

• At least two or more lab-confirmed COVID-19 cases in residents or staff (or other visitors) in a home with an epidemiological link, within a 14-day period, where at least one case could have reasonably acquired their infection in the home.

Acute care facility (e.g., hospital) outbreak: 

• At least 2 lab-confirmed cases of COVID-19 in staff or patients within a specified area (e.g., unit, floor or service) within a 14 day period. 
• At least 2 of those cases have a clear link of being acquired within the hospital (e.g., admitted for 5 or more days before symptom onset or no obvious source of infection outside the hospital).

Post-secondary residence (e.g., university residence):

• At least 2 lab-confirmed cases of COVID-19 in students or staff within a 14 day period.
• At least 2 of those cases have a clear link of being acquired in the residence (e.g., a known exposure in the residence or no obvious source of infection outside of the residence)

Child care centre (licensed child care or home daycare) outbreak: 

• At least 1 symptomatic, lab-confirmed case in a child, staff member or home child care provider, in consultation with the Medical Officer of Health.

School outbreak:

• At least 2 lab-confirmed cases of COVID-19 in staff or students reported within a 14 day period
• At least 1 of those cases has a clear link to being acquired within the school (e.g., a known exposure in the school setting or no obvious source of infection outside of the school setting).

Workplace outbreak:

• At least 2 lab-confirmed cases of COVID-19 in the same workplace (e.g. same work area, same shift) within a 14 day period. At least 2 of those cases have a clear link of being acquired in the workplace (e.g., a known exposure in the workplace or no obvious source of infection outside of the workplace).

What does community-spread mean?

Community-spread happens when individuals in the community are confirmed positive for COVID-19 but have no known contact with another confirmed case or have not travelled to an area with documented cases.

In order to slow or stop community-spread infections, everyone in our community must continue to practice infection prevention measures including hand washing, mandatory self-isolation for 14 days after returning from travel outside of Canada, and physical distancing.

What does no known epi-link mean?

KFL&A Public Health investigates all confirmed cases to determine how the individual contracted COVID-19. If an individual has no known contact with another positive case, and has not travelled to an area with confirmed positive cases, they have no known epidemiological link. If multiple cases within the KFL&A region have no known epidemiological link, this may indicate that there is community spread of COVID-19.

In order to slow or stop community spread, everyone in our community must continue to practice public health prevention measures including; hand washing, monitoring for symptoms, physical distancing from others outside your social circle of 10, and staying home when feeling sick.
