I'm afraid that may not be true (mild illness for most). RNA viruses are susceptible to mutation and there are indications that this virus has already mutated from a less virulent form. In the States the virus which caused the Spanish Flu is currently being recreated. They discovered an Inuit woman in Alaska who died of it but whose body was preserved in Permafrost. The Genome was then sequenced and the 8 viral genes were individually and synthesised packed in 8 seperate plasmids. There is currently plans to recreate this flu by reconsituting the 8 viral genes. This flu killed 100 million people.In a previous working life (related to the pharma industries and medicines research) we were warning (20 years ago) that
a) As a Society we are becoming more and more resistant to anti-biotics and anti-virals due to an over-reliance on these drugs and DEMANDING they be supplied via the NHS. In other words we are preventing the human race from evolving naturally as a species to deal with this sort of stuff; AND
b) We are TOO CLEAN (which impacts a)) driven by commercial marketing to over use disinfectants, hand gels, anti-bacterial soaps, cleaning all surfaces, etc. etc. in our homes and personal lives
We were predicting THEN that we were overdue a global pandemic of some form (Spanish flu after WW1 being the last really big one). Driven increasingly by the volume of travel (specifically flying) that rapidly spreads anything GLOBALLY.
Imagine if we'd only 'discovered' covid-19 AFTER the Olympics and all spectators, participants, athletes had contracted it and already flown home??
Who remembers the plagues in Europe these days and the impact they had...…..
Covid-19 is actually serious for those particularly susceptible......but for the majority of the population mainly a mild illness. BUT - this should be seen as a wake-up call before a truly big and nasty one arrives.....and it will.
