Is the Home Office betraying us?

Hmmm.. I can sort of see where the OP is coming from on this in regards to COVID19 possibly being brought in by migrants especially in view of the article in The Guardian on the 9th April:

“Now we know the virus is in the camps we urgently need the authorities to take action, and faster. The refugees can’t use the mitigation methods the rest of society are practising, like social distancing. Without these, the spread of the disease could be exponential and we estimate that half the population could be infected within four weeks.”

In April, 500+ migrants arrived on our shores and I have no idea whether they are taken to be quarantined or tested on their arrival but maybe someone else has more information regarding that? In any event, we still have open borders in regards to our airports and sail ports, with passengers arriving daily, albeit in reduced numbers than before the COVID19 epidemic. If we're not checking every single person who enters the UK, by whatever means of travel, we're not going to see the back of the virus for a very long time.

Germany took in many refugees and many of those refugees were doctors they have thousands more doctors than they would have had without Good on them miserable us trying to send all our overseas NHS workers home

We keep being told one of the reasons the numbers of deaths due to covid are high compared to Europe is the density of people. Honestly we are full up and going to have major financial hardship after this. The migrants will continue to come as they know they will not be sent back to the safe country they just left.

I was rather hoping we'd left that sort of inflammatory language behind with the Brexit debate.

Just how is the Home Office betraying us?
