New and active cases Vaccination rate Nova Scotia’s third and fourth waves Breakthrough infections Canada’s fourth wave
Saturday surprise!
Yesterday the province said there wouldn’t be any COVID reporting on the weekend. But here we are with a Saturday report, for the first time since Saturday, July 23. And it’s all thanks to the X-Ring outbreak. Way to go St. FX!
In what it’s calling “an abbreviated COVID-19 news release,” the province is reporting 129 new cases today. This update doesn’t say anything about recoveries, or what exactly the active caseload is. We are adding the 129 new cases to yesterday’s 301 active cases to arrive at an asterisk-enhanced figure of 430* active cases, because that’s technically what the province is reporting even though it’s likely there have been recoveries. With any luck the data overwhelm public health is experiencing will subside enough by Monday to give an updated caseload.
“There are 64 cases in Central Zone, 52 cases in Eastern Zone, 10 cases in Northern Zone, and three cases in Western Zone,” says the province’s report. “Public health notes that some cases associated with this outbreak are being counted in Central Zone because of the address on the student’s health card. That is why not all of these cases are reflected in the Eastern Zone numbers.”
Watch for another report tomorrow.
Comparing active cases in the third and fourth waves
In December, the town of Antigonish became ground zero for an inter-provincial COVID outbreak due to a weekend of superspreader events connected to the annual presentation of X-Rings at St. Francis Xavier University. But how bad is the outbreak, really? The following chart lets you compare Nova Scotia’s active cases, dating from the third wave in April through the fourth wave and its infection Xplosion, using case data from provincial pandemic reports. The chart will be updated when provincial reporting allows.

New and active cases visualized
Nova Scotia’s third wave of COVID grew in April, 2021, peaked in May (227 new cases in one day was the maximum) and subsided in June. On July 17, the province reached five active cases—its lowest level in more than eight months—and an election was called. So when it came time to reset The Coast’s chart comparing daily new cases with that day’s active caseload, in order to better reflect disease levels after the third wave, we started from July 17. Two months later, on September 14, the province formally announced the arrival of the fourth wave of COVID. The dark purple line tracks the rise and fall of daily new infections reported by the province; the green area is the province’s caseload. In mid-November, The Coast added a golden line to show the 7-day moving average of daily new cases, effectively a smoothed-out version of the purple line that puts the ups and downs into bigger context. Click or hover over any point on the graph and the detail for that moment will pop up. To focus on just some information, click the legend at the top left of the graph to hide or reveal that data set. Note: As of July 23, 2021, the province stopped updating case numbers on weekends. And you can click here for the version of this graph that includes the third wave and its May 10 crest of 1,655 active cases.

Vaccination in the population
How many Nova Scotians already have one dose of vaccine? How many are fully vaccinated with two doses? And how close are we to the herd immunity goal of 75 percent of the province fully vaxxed? These questions are answered in our chart of the vaccination rate in Nova Scotia since the province started reporting these numbers in January 2021, breaking out people who’ve had a single dose separate from those who’ve had the full complement of two doses. (Here’s more information about the 75 percent target and what it will take to get there.) Note: The province doesn’t update vaccination numbers on weekends.

Canadian cases in 2021
There was a point in July 2021, when the delta variant was causing an increase in COVID infections around the world, that Canada seemed safe from the fourth wave. By August, however, that point had passed, and case numbers around the country started to rise again. This graph charts the number of new infections every day in each province and territory, using the 7-day moving average to mitigate single-day anomalies (including a lack of weekend reporting in several jurisdictions including British Columbia and Nova Scotia).

Breakthrough infections in Nova Scotia
On Fridays, the province’s daily COVID report includes statistics about COVID breakthroughs—infections, hospitalizations and deaths among people who are fully or partially vaccinated. The province reports its numbers as a cumulative total: all the breakthrough cases dating from March 15, 2021 to the latest update. The Coast does an analysis to break the information about new cases down by each weekly reporting period, in order to offer our readers the following unique view of the same information, so you can better understand the fluctuations in breakthrough infections as they happen. Note: Our bar chart only dates back to June because the province didn’t start this reporting until summer 2021.
