It’s too late as there is person to person transfer all over the UK and as testing is only happening sporadically tracking individual cases and who they have been in contact with is now all but abandoned.
The only solution is to ‘squash the sombrero’ as the PM said (oh dear) to keep the casualties down.
This came from the North East PHE (Public Health England) Director, an area that has not been hit too badly so far:
‘We are approaching a critical phase and make no mistake, the North East cannot avoid the very real consequences of this disease. We need to protect ourselves, our families, our key workers and every community across the North East. To do so we must act now. Every single one of us in our region must take responsibility’.
