Re: Strains, Strains, Strains, Strains.
Australia is also highly connected and had a lot of early cases due to the many Chinese contacts in Australia. IIRC there were actually more known cases in the first couple of weeks in Oz than in the UK.
The UK might be in visual distance of Europe, but unless everyone decides to swim over you can still close borders. You have to stop importing new cases so that you can deal with the ones already there.
Taiwan and Vietnam are both in visual distance of China, a land border in Vietnam's case. They still stopped the virus dead in its tracks with early, hard action.
