Data tables for ONS Neighbourhood COVID-19 Maps (Historical)

<p>Cumulative and monthly counts and rates of confirmed COVID-19 in Ottawa neighbourhoods, excluding cases linked to outbreaks in long-term care homes (LTCH) and retirement homes (RH). Based on the most up to date information available at 2pm from the COVID-19 Ottawa Database (The COD) on the day the data is pulled to provide the monthly update.&nbsp;<br /><br /><strong>Accuracy</strong>: Points of consideration for interpretation of the data:&nbsp;<br />&nbsp;</p><ul><li>Data extracted by Ottawa Public Health at 2pm from the COVID-19 Ottawa Database (The COD) the day prior to publication. The COD is a dynamic disease reporting system that allow for continuous updates of case information. These data are a snapshot in time, reflect the most accurate information that OPH has at the time of reporting, and the numbers may differ from other sources.&nbsp;</li><li>A case (an individual with laboratory-confirmed COVID-19 infection) is assigned to an Ottawa Neighbourhood Study (ONS) geography based on the individual’s residential postal code and the ONS’s postal code conversion file. As the area served by a given postal code may cross multiple neighbourhoods, the ONS postal code conversion file identifies the proportion of each postal code that falls within a neighbourhood. Thus, for cases with postal codes falling within multiple neighbourhoods, a fraction of those cases will be assigned to each neighbourhood.&nbsp;</li><li>Rates calculated from very low case numbers or for neighbourhoods with very small populations are unstable and should be interpreted with caution. Low case counts have very wide 95% confidence intervals, which are the lower and upper limit within which the true rate lies 95% of the time. A narrow confidence interval leads to a more precise estimate and a wider confidence interval leads to a less precise estimate. In other words, rates calculated from very low case numbers fluctuate so much that we cannot use them to compare different areas or make predictions over time.&nbsp;</li></ul><p>&nbsp;</p><p><strong>Update Frequency</strong>: Monthly&nbsp;<br /><br /><strong>Attributes</strong>: Data fields&nbsp;</p><ul><li>ONS Neighbourhood – text<br />&nbsp;</li><li>Cumulative rate (per 100 000 population), excluding cases linked to outbreaks in LTCH and RH – cumulative number of residents with confirmed COVID-19 in a neighbourhood, excluding those linked to outbreaks in LTCH and RH, divided by the total population of that neighbourhood<br />&nbsp;</li><li>Cumulative number of cases, excluding cases linked to outbreaks in LTCH and RH - cumulative number of residents with confirmed COVID-19 in a neighbourhood, excluding cases linked to outbreaks in LTCH and RH<br />&nbsp;</li><li>Monthly rates (per 100 000 population), excluding cases linked to outbreaks in LTCH and RH –number of residents with confirmed COVID-19 in a neighbourhood reported to OPH during the month of interest, excluding those linked to outbreaks in LTCH and RH, divided by the total population of that neighbourhood.&nbsp;</li><li>Monthly number of cases reported, excluding cases linked to outbreaks in LTCH and RH - number of residents with confirmed COVID-19 in a neighbourhood reported to OPH during the month of interest, excluding cases linked to outbreaks in LTCH and RH.&nbsp;</li></ul><p><br /><strong>Contact</strong>: <a href='mailto:[e-mail]' rel='nofollow ugc'>OPH Epidemiology Team &amp; Ottawa Neighbourhood Study Team | Epidemiology &amp; Evidence, Ottawa Public Health</a></p>
