Covid-19 Update: 19 October

I took a holiday yesterday. To be honest, I’ll be taking a lot of short holidays as the year winds down on account of not taking any the first three quarters of the year. So expect quite a few quiet Mondays and Fridays in the next few months.

But back to Covid-19. I won’t have a lot to say in this weekly update, because I didn’t write anything last night when I made these. Suffice it to say that things are bad and getting worse. Although, things could also be much worse. And by that I mean, while we are seeing dramatic rises in new cases, we are not yet seeing the rises in deaths that accompanied similar rises in March and April.

Although it should be said that while still low, deaths have been rising. The easiest seen instance of that is in Illinois, below. You can see deaths are rising slowly upwards and the state is approaching 50 deaths per day. While that is still off from the peaks of 100+ earlier this year, that’s still too many people.

Covid-19 Update: 28 September

Apologies for the lack of posting, work is pretty busy as we wrap some projects up. But here’s a look at the latest Covid data for Pennsylvania, New Jersey, Delaware, and Illinois. Normally we look at Virginia as well, but their site was down for maintenance and so there was no data to report.

When it comes to new cases, we have on the one hand places like New Jersey and Illinois, where new cases continue to rise. The rate is nowhere near as fast as it was in March and April, but the inclines are clearly there. Delaware has been up and down, but largely hovering around just shy of 100 new cases per day. Pennsylvania is a bit harder to tell because of some dramatic swings that have knocked the average around, but it does appear to be trending upward, though I’m not quite as confident in that as I am with New Jersey and Illinois.

And then when we look at deaths, we generally have good news. Last week we were looking at Virginia and its working through a backlog of unreported deaths. That artificially inflated recent days, but also depressed deaths earlier in the pandemic. Beyond the old Dominion, however, deaths have remained fairly low. Only in Pennsylvania and Illinois do they hover around 20 deaths per day from the virus.

Covid-19 Update: 21 September

Apologies for the lack of posting yesterday, but I wasn’t feeling well. I had some other things planned for today, but then some other things happened this weekend and then I took ill. But it’s still important to look at what’s going on with the pandemic, especially in the United States where it’s been disastrously handled by the White House.

As we approach 200,000 dead Americans, we still look at what’s going on in the tristate region alongside Virginia and Illinois. Specifically we compare last week’s post to this week’s post. Note that normally we look at Sunday data on Monday morning and today we’ll be looking at Monday data on a Tuesday. Both Sunday and Monday are reports from their preceding days, and so we are still looking at weekend reporting of figures. So we can expect them to be lower than workweek data.

If we compare the above chart to last week’s, we can see that Pennsylvania has decidedly reversed course. Whereas things had been headed down in terms of averages, I was worried about the days of daily new cases exceeding the average. Sure enough the average has caught up to the new cases and we’re seeing a rise in the average to levels not really seen since the summer.

New Jersey remains on the path of slowly increasing its numbers of new cases. Delaware looks to be heading back down after a small bump. We might be seeing the beginning of a decline in cases in Virginia, down from its long-running plateau of nearly 1000 new cases per day. And finally in Illinois, it’s not quite clear where things are headed at present. But for the one-day spike that raised the average, it seemed as if new cases had been in decline, but the end of that otherwise decline might have been an inflection point as the average may be trending back upwards again.

Then when we look at deaths, well we see no real significant change in four of the states. But last week, we were saying Virginia was at a good spot with its latest surge cycle coming to an end. Well now look at that spike and deaths that are higher now than they were in the spring. If you follow my daily posts on social media, you’ll know that there’s a reason for this.

For the last week Virginia has been working through a backlog of deaths that were not entered into its electronic database. And so these deaths happened over the last several months. Consequently the rise, if there even is one, is not nearly as high as shown. But it also means that the earlier peaks may have been far higher than reported at the time.

Covid-19 Update: 13 September

Apologies for the lack of posting last week. I’m on deadline for, well, today. Plus I had some technical difficulties on the server side of the blog. But it’s a Monday, so we’re back with Covid updates for Pennsylvania, New Jersey, Delaware, Virginia, and Illinois.

New cases curves for PA, NJ, DE, VA, & IL

The good news, such that it is during a global pandemic, is that in Pennsylvania, Delaware, and Illinois, the seven-day average appears to be lower than this time last week or, especially in Delaware’s situation, about to break. For the First State, I’m looking at those days prior to the weekend below the average line that, in combination with the weekend, will likely begin to push that trend downward, especially if we keep seeing fewer and fewer cases this week.

Unfortunately, some states like Virginia and New Jersey appear to be, not surging, but experiencing low and slow growth. Low and slow, while great for barbecue, is less than ideal during a pandemic. Granted, it’s better than the rapid infections we saw in March, April, and May, but it still means the virus is spreading in those communities.

Death curves in PA, NJ, DE, VA, & IL.

When we look at deaths from Covid-19 in these five states, the news is better. The only real significant level of deaths was in Virginia, but we can see that the latest little surge, which was at peak last week, has now all but abated, almost to a level not seen since the spring.

The other states remain low with, at most, deaths average about 20 per day. Again, not good, but better than hundreds per day.

Covid-19 Update: 7 September

Yesterday was a holiday in the States, and so let’s begin this shortened week with a look at the Covid situation in Pennsylvania, New Jersey, Delaware, Virginia, and Illinois.

If we compare this morning’s charts of yesterday’s data to last Monday’s, we can see some concerning trends.

New case curves in PA, NJ, DE, VA, & IL.

In Pennsylvania, that includes a rising trend. Anecdotally, that might be tied to the outbreaks in and around universities. We see rising trends in Delaware and Virginia as well, though some of Delaware’s new numbers might be tied to some cases that failed to initially make into the state’s digital database. And so as the state begins to enter them now, it artificially inflates the new case numbers.

Illinois had an enormous spike of cases from a backlog that the state entered, over 5,000 new case in that one day. That’s going to mess with the average trend given the size of the anomaly. So we’ll need to wait until later this week to see where the trend really is.

Then in terms of deaths, the most worrying state was Virginia which last week was mid-peak. But that appears to maybe be trending back down. Though the data we have does include two day’s of weekend numbers and Tuesday’s numbers, instead of the usual “rebound” will be more of the usual weekend depressed numbers.

Pretty Much My Life These Days

It’s another Friday. Which means another work week come and gone. Most of my days now consist of Covid-related work. A couple of months ago, Memorial Day began the surge in Covid-19 cases. Hopefully people take it more seriously now, and everyone masks up and stays distant so that Labour Day does not become a new big inflection point. Consequently, this piece from xkcd feels most appropriate.

For my American audience, since it is a holiday weekend, again, enjoy Labour Day. For my British audience, you already had your summer bank holiday. For everyone, have a good weekend.

Wear a Mask

It sounds so easy, but too many don’t do it.

Yesterday, Agence France-Presse published an article about a recent study in the Journal of the American Medical Association that examined the efficacy of the coronavirus’ airborne spread potential.

The study centred on a bus trip in eastern China from January, before the widespread adoption of masks as common courtesy let alone mandated safety equipment. Nobody on the bus of 68 travellers wore a mask and the bus’ air conditioning system recycled the air inside the vehicle. (Remember the importance of cycling and filtering air inside subway cars?)

Researchers then mapped the location of patient zero, conveniently from my point of view in the centre of the bus. It should also be noted that patient zero was also asymptomatic at the time of the bus trip. Then researchers mapped the seats of those infected on the bus and this is what they found.

One of the key findings is these conditions, recirculated air amongst people not wearing masks, the virus was able to infect people outside the 2-metre safety radius (6-feet in the non-metric States).

Now from a design standpoint, I really like this graphic. It shows people’s seats and their condition to show the physical spread of the virus from patient zero. (Eerily, people far away were infected whilst one person sitting next to patient zero remained uninfected.) Not only that, but from a chain of transmission standpoint, the designer also included how many people these newly infected victims infected. Some infected nobody further whilst others infected up to four additional people.

My only real quibble here is with the colours used for the status of the infected. I think the light grey works well for those who were not diagnosed with Covid-19. But the green, yellow, blue, and red don’t quite work for me here. The value of the yellow is too close to the grey and consequently almost the mildly symptomatic people fall almost into the background. Compare that to the asymptomatic victims in green, who appear far more prominently.

I understand the desire to progress from mild to moderate vs. asymptomatic. So I wonder if those with mild symptoms were given a light blue and those with moderate a dark blue to contrast with the asymptomatic green. Of course, we still run into the red-green issue, but the dotted circle around patient zero mitigates that concern.

Remember, this was all among people not wearing masks. This piece strongly shows how important it is to wear a maskā€”not just to reduce the risk of receiving the virus, but to reduce your risk of spreading the virus if you are an asymptomatic case. (To be fair to the people on the bus, we knew very little about the virus in January and who knows what they knew as China was still attempting to downplay the virus.)

The point? Wear a mask.

Covid-19 Update: 30 August

After dealing with hurricane forecast plots last Monday, we’re back to the nature-made, man-intensified disaster of Covid-19 in the United States. So in the five states we review, where are we with the pandemic?

Compared to the charts from two weeks, looking at daily new cases, in some places we are in a better spot, and in others not much has changed. In fact Illinois is the only place worse off with its seven-day average higher than it was two weeks ago, but not by dramatically much.

New cases curve in PA, NJ, DE, VA, & IL.

In fact we see in Pennsylvania, New Jersey, and Delaware that the average number of daily new cases is lower than it was two weeks ago. Virginia dipped lower, but has recently returned to approximately the same level and in that sense is in no different a place. Of course the key factor is how those trends all change over the coming week.

But what about in terms of deaths?

Deaths curve in PA, NJ, DE, VA, & IL.

Well here there is bad news in Virginia. Two weeks ago a spike in deaths there had largely subsided. Two weeks hence? We are in the middle of a third spike of deaths, reaching nearly 20 deaths per day.

Fortunately, the other four states remain largely the same, and that means few deaths per day. Indeed, for Pennsylvania and New Jersey that means deaths in the low double-digits or often in the single digits. Delaware has not reported a new death in four days. And Illinois, while up a little bit, is in the low single-digits, but generally just a few more deaths per day than Pennsylvania and New Jersey.

Is Covid-19 Surging in New Zealand?

Yesterday, President Trump claimed that Covid-19 was “surging” in New Zealand, a country widely lauded as having successfully contained and suppressed their outbreak. That has allowed Wellington to reopen large swathes of their economy without incident.

Until this surge.

And by surge we mean something like 30 cases in 3 days. So, let’s compare that surge to the numbers of new cases in the United States.

Now, to be fair, New Zealand has a population of nearly 5 million, the United States has nearly 335 million. So a direct number-to-number comparison of the number of new cases per day isn’t fair.

So let’s look at the number of new cases per million people, which equalises the data for population.

So yeah, New Zealand is not “surging”. The data shows that even with the more limited testing per capita conducted in the United States, we are nowhere near the point of bending the curve anywhere close to zero.

Covid-19 Update: 16 August

So here are the charts from the last week of Covid data in Pennsylvania, New Jersey, Delaware, Virginia, and Illinois.

When we compare last week’s update to today’s, we can see that Pennsylvania did indeed bottom out and is back on the rise and the same can probably be said for Delaware. Although a fair amount of the one-day spikes in those numbers we see today are from an outbreak in a correctional system.

Whilst Virginia did go up, by week’s end, it had settled back down to a point not dissimilar to last week. So nothing really changed and time stood still in Virginia. The same can also be loosely said for New Jersey, where it was more about fluctuations than determined rises or falls.

In Illinois, however, we finally saw a plateauing of the new cases numbers and with the slightest of declines .

Then in deaths we have not much to say as they remain low in New Jersey and Delaware and stable and moderate in Illinois.

Virginia’s recent spike appears to have subsided, as it’s back to nearly 10 deaths per day from the virus.

But most concerning is Pennsylvania. Here, while the numbers are still relatively low, they are on a slow and gradual rise. At this point the seven-day average is beginning to rise above 20 deaths per day.
