Covid-19 Key Indicators
The truth is like a lizard; it leaves its tail in your hand and runs away; it knows that it will shortly grow a new one. – Ivan Turgenev
I acquire coronavirus data daily for certain California county websites, like Sonoma County, that display it [1]. Then I calculate some key indicators for the virus that might be useful to understand and control it. You can find out more about them at Coronavirus Key Indicators Description. According to official California statistics, the population of Sonoma County is 509,142. [1] I use my PHP program CoronavirusScrape.php.
Marin County, adjacent to Sonoma County, has similar data available, and its results are shown at Marin County Coronavirus Key Indicators.
| County | doubling.rate | start.day | end.day | Date | mean R | Infections per day |
|---|---|---|---|---|---|---|
| Sonoma | 55.81 | 8 | 364 | 2021-03-09 | 0.86 | 14.61 |
Data may be newer than comment below, as I do not comment every day.
Current Comment and KPIs
3/10/21- Mean R is now at 0.86. Infections per day are over 14, down for the first time in a while. Doubling rate is over 55 days.
I will occasionally refer to a mobility graph, which uses the Google Mobility Report data to show where the county stands on social isolation and social distancing practices. Mobility data appears to be one of the best ways to predict the trend of the virus. Mobility information is at Coronavirus Mobility Indicators.
