PROVINCIAL UPDATE 20 JULY

• Changes from yesterday highlighted
• Cumulative cases graph
• Comorbid diseases table

Cases from WC have been reallocated so numbers have gone down there, as a result I can't work out what the actual increase for cases and recoveries were today. Cumulatve cases graph

FS curve the one that stands out on this graph by the way it's been bending up.
Here's a quick comparison of number of days to go from 1000 to 10 000 cases to give you an idea of the growth in FS:

FS - 24
WC - 28
EC - 37
NW - 37
GP - 59
KZN - 62

PROVINCIAL UPDATE 20 JUNE

• Changes from yesterday highlighted
• No hospital update given today

Since, according to the official numbers, GP now has more active cases than WC... today I'm going discuss why maybe that's not actually the case.

#Covid19SA #COVID19inSA I know there's going to be a lot of talk about GP now having more active cases than WC, but in theory, I don't feel it's true.
Since WC changed it's testing strategy, the dip in the 7 day average was very noticeable - and not consistent with I expected from the curve.

PROVINCIAL UPDATE 20 MAY

• Changes from yesterday highlighted
• 7 day average graph

Today saw the most recoveries recorded in one day (990), and more recoveries than new cases for once.
Media always seem to report the negatives, so just trying to look on the bright side :) 7 Day rolling Ave graph (As of 20 May):

• WC growth rate slowed in the last few days
• KZN and GP meandering along the same path for a while now
• Still too early, I feel, to say if the smaller provinces are experiencing any serious growth
