Test positivity rates are dramatically lower compared to mid-November. See charts below for more details.  

The graph below shows trends over time of COVID-19 cases and deaths in the Quad Cities. Note the difference in recent decreases in Rock Island County deaths (red line) and Scott County deaths (black line).  

The image below is a simple line graph of COVID-19 cumulative cases. 

This graph shows both daily and cumulative COVID-19 deaths.   

Above is a view of Rock Island County and Illinois Region 2 seven-day rolling average test positivity rates (percentage). And below is a more limited view of Scott County seven-day moving average individual test positivity rates.     

The following graph shows monthly Quad Cities cases and deaths.

The next one shows Rock Island County cases and deaths reported during the first halves of the past four months.

The latest statistics about COVID-19 in Rock Island County long term care centers is shown below. The number of "open" cases is 992 over the last month. That's 77% of the total since the pandemic began (1,296).

Iowa does not provide similar data for Scott County. The Iowa DPH COVID-19 website currently shows one facility, Ridgecrest Village, has had 22 cases with 14 recoveries in the last two weeks. That means eight cases are "active" (similar to "open" in Illinois).

As of Sunday, the total number of Quad Cities COVID-19 cases is 26,302 (11,341 in Rock Island Co., 14,961 in Scott Co.) with 431 deaths (276 in Rock Island Co., 155 in Scott Co.).

(Case fatality is useful to track trends but is a poor measure of infection mortality, according to the CDC.)

Quad Cities monthly cases and deaths during the pandemic so far are shown in the graph below. 

The next graph shows case and death trendlines for both counties since March.

Here's a look at the case recovery rate in the Quad Cities.  

Illinois Region 2 and Rock Island County 7-day rolling average test positivity rates are shown below.

The next graph features Scott County recent test positivity rates.  

In Rock Island County, 60% of COVID-19 deaths have been long term care residents, but only 11% of the county's confirmed cases have been at those facilities.

As the number of confirmed COVID-19 cases decreases, the number of Quad Cities residents dying of the disease is rising. This trend began in November with a dramatically increase in the monthly case count  (10,013, Rock Island and Scott counties combined) followed in December by a 50% drop (5,008).

For November, the case fatality rate (CFR) was 0.88%. (CFR is the proportion of the number of deaths divided by the number of confirmed patients.) For December, the case fatality rate increased to 3.47%, or nearly four times higher than November.

The bar graph below shows the Quad Cities recovery rate since March. 

The recovery rate only includes Quad Cities residents who had a positive COVID-19 test result and survived. It does not include the unknown number people living in Rock Island and Scott counties who were infected with the coronavirus disease (with or without symptoms) who did not get tested. Researchers say in a few years, serology (or blood) tests for COVID-19 antibodies may be able to reveal the true infection rate of the population.

The Rock Island County Health Department reports 12 more residents have died, bringing the total to 243.

It's the highest number of COVID-19 deaths reported on one day, but it's also probably because of delayed reporting over Christmas and the weekend. Rock Island County's case count is now 10,653. 

The Scott County Health Department reports a total of 147 COVID-19. Scott County's case count has reached 13,824. 

The total number of COVID-19 deaths in the Quad Cities (both counties) is now 390, and the case count is 24,477. To put those number is context, so far in December, 156 Quad Cities residents have died of COVID-19. That's nearly twice as many as November when 88 died. But the number of positive cases reported this month has dropped to 4,565, less than half the 10,013 cases reported in November.    

Here are some updated graphics showing the data and trends.

The number of COVID-19 cases and deaths continues to rise in the US, Illinois, Iowa, and the Quad Cities. To give more context, the second slide in the slide show above features a line graph with two axes plotted over the same timeframe. Keep in mind they are not to scale or equalized by using figures per 100,000 population. (In other words, the numbers should not be compared by how high they are in relation to one another.)

You may compare cases vs. deaths by increases and decreases. For example, did an increase in case numbers over the Fourth of July result in an similar increase in deaths a few weeks later? 

The third slide also features a secondary axis, so the same caution applies. It's monthly cases and deaths reported in the Quad Cities.

In the graph below, the light green line shows the number of Scott County COVID-19 cases is slightly higher at 3,477 compared to the number in Rock Island County, 3,415.

Since the pandemic began, Scott County's numbers have trended slightly lower than Rock Island County's.

But for the past eight days, it's reversed. 

Over several months, Scott County's overall positive test rate has been slowly rising  compared to Rock Island County's which has been flat to increasing slightly (see graph below).
