Cases

Five months ago, I was wondering why Maryland remove COVID-19 cases from its count in congregate living facilities (nursing homes, prisons, …). I still don’t have any answer but I found a technical solution :-) The Python script (in src/ in the MD-coronavirus repo on Github) just fills in the latest data for days where data is missing. On a side note, it also fix some basic issues like a reporting date in year “0200” (instead of “2020”). You can play with the fixed data file here. ...

Every day, Governor Hogan and members of his team are communicating news on the COVID-19 situation in Maryland via Twitter (and other media): @GovLarryHogan, @riccimike, @katadhall, … (and of course: @MDHealthDept too!). A number of data enthusiasts are also parsing the MD Department of Health data: @TylerFogarty7, @MikeBReporter, @JauquetW, @PrayagGordy, … and of course: @jepoirrier) … And this is only on Twitter! But also every day, there is one thing that constantly changes: how everyone is calculating the COVID-19 positivity rate. Today (July 26), for instance, the different daily positivity rates announced are: 3.77% ( Hogan), 4.47% ( Hogan again in the same tweet, Hall, Ricci, MD Health Department, Fogarty) and ~6% (for me, the exact number behind the ~ is 6.14%). This doesn’t show the 7-days (or n-days) averages and other measures. And this is only on Twitter. ...

After my previous posts about age of COVID-19 cases and deaths in Maryland, it was logical that I write about the gender of these cases and deaths. Rest assured: this time, it will be much shorter ;-) Indeed, in a nutshell, in Maryland (like in the rest of the world), women are more impacted than men by the disease. But men are dying of the disease a little bit more than women. Note: this post was updated on July 15, 2020, to fix an error in my code! ...

We recently heard in the US media that, if COVID-19 affected more the older population, beginning of 2020, the younger population was now more affected, especially young adults (various reasons were mentioned: the various academic breaks, being more active or “forced” to work, the sentiment of invincibility …). I wanted to see if one could see a similar trend in Maryland. If you look at the section of the Maryland population by age (graph below), as of today (July 9, 2020), you see that cumulatively, people 30-39 have the majority of cases, followed by people aged 40-49, 50-59 and 20-29 years old. There are relatively few cases above 70 years old and fewer cases below 20 years old. ...

Since the beginning of the COVID-19 pandemic, we suspected and saw that nursing homes and other facilities where people are grouped together (prisons, …) could be at higher risk of transmission. The focus on nursing homes was because deaths seem to disproportionately affect the older population that also resides there. And nursing homes are also home for frail people with comorbidities. In its dashboard, the Maryland Department of Health quickly started to build a dedicated page with numbers from different “congregate facility settings”. As I did for other metrics from this dashboard, I made a chart of what seemed the cumulative total cases, differentiating staff (who are stuck working there) and residents (who stuck living in these facilities): ...

A publicly-available MD COVID-19 metrics that I didn’t investigate much is cases per ZIP code. I created a dashboard where you can highlight one zip code at a time. Tyler Fogarty built a cool Treemap Explorer. Silver Chips has a nice heatmap of all zip codes as part of their extensive dashboard (a bit like the MDH dashboard). How can we make sense of all this? A classical way to see it is to look at the daily number of positive cases, similarly to what I did for counties or the state. ...

Since May 14, 2020, Maryland is carefully reopening from an easy lock-down caused by coronavirus spreading thru the community (and all over the world). In this post, I’ll go through all the variables we have on the MD Health Department dashboard. But first, the official data comes from the MD dashboard and if you want scientific information about COVID-19, please consult the CDC website. If you are interested, you can read my previous posts on COVID-19 in Maryland from this page. ...

In my previous post, I was wondering if Maryland was ready to reopen, ready to enter Stage 1 of COVID-19 recovery. I also mentioned, in the end, that if Gov. Hogan announced the reopening of Maryland, he also gave counties the power to “fully” open, to be partially open or even to remain closed. You can see more info about Maryland Strong: Roadmap to Recovery: there is a map of what Counties decided. ...

Following up on my two previous posts ( here and here), I am writing a third post on COVID-19 in Maryland because I believe we enter a new phase. Before continuing, please note that the same disclaimer as in my previous post applies here (in short: read the CDC and MDH websites for official information). In the first phase, the importance was to detect and make sure COVID-19 patients were treated (also: make sure not to overwhelm the healthcare system, flatten the curve, lower the baseline, & stay at home!). My two previous posts were following these efforts, thanks to daily data released by the Maryland Department of Health (MDH) on its dashboard. My second post will still be updated with the latest data from there, go read it! ...

This post was last updated on April 26, 2020. A new post from April 27, 2020 is here. Following up on my previous post, here are updated trends in Coronavirus cases in Maryland (USA), the state I live in. I am writing a second post because the Maryland Department of Health (MDH) updated its dashboard with way more data than before (more on this below). Before continuing, please note that the same disclaimer as in my previous post applies here (in short: read the CDC and MDH websites for official information). ...
