Closing borders may be an effective way of preventing the spread of Covid-19, argues Steve Watson of Summit News. A study from Brazil found that countries that permitted unrestricted travel during the beginning of the pandemic ended up being hit hardest. Countries like Austria, Denmark and New Zealand that closed down their frontiers early on ended up with much fewer fatalities. The UK chose to keep its borders open and saw many more of its citizens perish from the virus; the US did the same and saw a similar outcome with many Covid-19 deaths. Keeping tighter control of borders can protect communities against the danger of Covid-19.
Closing borders appears to be an intuitive way of limiting new variants from spreading, but it is ineffective, asserts Susan Matthews of Slate. More often than not it is too late to make any difference. Many countries panicked at the discovery of the Omicron variant by closing their frontiers, but the fact of the matter is that we don't know whether this mutation makes the virus more dangerous or not. Nations should be less concerned with closing their doors, which harms economic growth and breeds alienation, and understand that this is a global virus that humanity needs to tackle together, for example by sharing vaccines with poorer countries.
