Not ideal, but the fact they are spread out to roughly 1 case per club means they are not spreading it amongst each other.
The flip side of that is it means players have possibly not been following social distancing carefully enough in day-to-day life.
Some other points:
It doesn’t state if the players who previously tested positive were included in these results. With such a small number of cases, it would make a big difference. I suspect the EFL would state if that was the case, as it would improve the stats (though they might not be able to due to medical anonymity)
There was a slight increase in number of tests from the last round – 28 more tests
The PL had zero cases in the latest round of testing, so we are a little bit behind them. PL – 12 positives from three rounds of testing, EFL – 15 positives from 3 rounds. PL has actually done more tests despite fewer clubs.
