which is also described in closed forum topic:

- [COVID-19 status by country](https://discourse.nodered.org/t/covid-19-status-by-country/28743)

**Extension:** Now it also reports for the US states the reproduction number up to 28 weeks ago.  
Take care it takes some time before the UI table is updated.

This has likely been asked already in the previous thread I avoided to check but what do the 9999 cells represent?

9999 is actually "infinity".

It just means that the respective week there were 1 or more confirmed cases, while the week before there were no cases.

FYI The reproduction numbers shown in the chart are calculate by following formula.

```auto
(number of confirmed cases in week X)/(number of confirmed cases in week before week X)

```
