I created this post to track COVID-19 in the US, starting on March 2, 2020, through September 23, 2020. As time progressed, I developed some tracking fatigue and stopped adding daily stats and links to related stories that I thought were interesting.

Rt is a key measure of how fast the virus is growing. It’s the average number of people who become infected by an infectious person. If Rt is above 1.0, the virus will spread quickly. When Rt is below 1.0, the virus will stop spreading.

Illinois is currently measuring R 0.89 - which makes me very happy as a Chicago resident:

More information on Rt can be found at rt.live.

When Congress passed legislation mandating paid sick leave during the pandemic, it exempted 80% of American workers (the requirement does not apply to any business with more than 500 employees). Some lawmakers say their top priority in the next relief bill will be a liability shield for companies as states reopen, while others focus on worker protections.

10K Americans reach 65 each day, and many are getting caught in the country’s broken retirement system. Notes:

  • Over 30M Americans have applied for unemployment benefits since the pandemic struck - many will lose their jobs permanently and retire earlier than planned.
  • 50% of Americans between the ages of 56-61 had less than $21,000 in retirement savings in 2016 - and not much has changed since (source).
  • 40% of Americans over the age of 60 who are no longer working full-time rely solely on Social Security for their income — with a median annual benefit of ~$17,000 (source).

A Congressional oversight committee released a report on the CARES Act’s s $500 Billion Emergency Economic Stabilization Funds. Highlights:

  • More than one quarter of the U.S. economy has been idled — a fall in output equivalent to what occurred between 1929 and 1933 during the Great Depression.
  • Over the eight weeks ending on May 9, 36.5 million Americans filed unemployment claims. When combined with the 7.1 million Americans already unemployed as of March 13, the total equals more than 40 million. Between people who are unemployed and underemployed, some experts estimate that the real unemployment rate is actually 22.8% or as high as 25%.
  • A Federal Reserve survey found that among people who were working in February, almost 40% of those in households making less than $40,000 a year had lost a job in March.
  • Of the $500 billion allocated, the Treasury Department has dispersed $37.5 billion to the Federal Reserve.

All 50 states have begun to reopen to some degree - many states require masks and for folks to social distance when gathering.

A prototype vaccine has protected monkeys from the virus. Small numbers (8 monkeys), but a great development nonetheless.

CDC releases guidance for reopening. A 60-page document that is similar to the draft version that was shelved by the White House, but with toned down guidance and section on ‘communities of faith’ removed.

Digging a bit deeper, I thought I’d look at aggregate stats in Cook County (home of Chicago, where I live):

  • Total population: 5.15M
  • Total cases: 88,650 (1.72%, or 1 in 58)
  • Total deaths: 4,500 (0.087%, or 1 in 1,145)

In my neighborhood, Lincoln Square, or zip code 60625:

  • Total population: 78,651
  • Total tested: 9,198 (11.6% of the population)
  • Total cases: 1,496 (1.9%, or 1 in 52)
  • Total deaths: N/A

I’m not sure why the deaths are not being reported on a zip code level. If we use the COVID-19 mortality rate of Cook County (0.087%) above, we can infer roughly 68 deaths in the neighborhood.

A helpful tool to view and filter on time series data for the city of Chicago. For example, my neighborhood:

2020-06-30 60625 COVID-19 Dashboard

How Much Testing Do We Need? Great analysis from NPR on state by state testing. Two thirds of states are not doing enough testing, a big reason (coupled with reopening too early) as to why we’re seeing a resurgence in large parts of the country.

I thought it was helpful to see a case study view of a mitigation strategy in Tennesse:

2020-06-30 Mitigation Case Study

Contrast this with a supression strategy in Italy:

2020-06-30 Suppression Case Study

The key difference is that cases are detected and isolated before they lead to outbreaks. Extremely logical.

Scrolling up, I notice we crossed the 2M case mark roughly 30 days ago. It’s hard to see where this ends. Everyone needs to listen to medical experts and do the part. We are all in this together.

July study from the Center on Budget and Policy Priorities shows 29 million adults (or 1 in 8) in the US report not having enough food to eat. 1 in 5 renters behind on rent. Data shows that families are being hit particularly hard. Thank goodness for programs like this in Chicago.

The US hit 200K deaths in the past few days – a grim figure.
