Mr F Oliver (Letters, last week) may have been studying this Covid virus, but he has obviously not studied wider history. Indeed his claims of “diseases that breed in the heat” hardly applies to the cold-loving Covid virus or many other infectious diseases.

Yes, people moving around obviously is an issue, but people who live in a country ruled by the British state, should remember that its Imperialist expansion took many diseases such as measles, chicken pox and whooping cough to the countries it invaded, as other imperialist powers did.

Not having immunity to these diseases, that had bred in the cool, those countries suffered devastating epidemics.

The lesson of Covid and other infectious diseases is not that countries can hide behind their borders. It is that the unit of human society is the planet. None of us will be safe until such diseases are wiped from everywhere on earth. We have done it with smallpox, polio and other diseases. We now have to do it with Covid, and may well have to do it in the future with other diseases, wherever they arise. Human mobility may be an issue, but the answers are solutions that cross all borders.
