How is this news at all? The virus has been mutating and throwing off different strains all along. There are entire websites devoted to tracking these, e.g., [1]
Perhaps this is just the normal operation of American media to exaggerate the negative side of the situation? [2]
It's news if there's anything notable about the strain. More deadly, faster spreading, potentialy resistant to the vaccines.
So far UK and South Africa have two strains that are faster spreading (and hopefully that's the only difference). If there's nothing special about the one from Japan, I bet that this is just getting attention because the other two are in the news. Either news orgs jumping on a bandwagon or HN readers expecting that it's similar when it's not.
But maybe this one actually is notable too, I don't know.
The South African variant is almost certainly not spreading faster because of the variant but because there were super spreader events like recently 1000 people tested positive after going to a night club [1]. Indoor weddings, funerals, and other big events have contributed too. While people wear masks (badly) outdoors and in shops, I think the root cause is bars, clubs, shebeens, etc. The government is also reluctant to introduce a new lockdown for fear of the damage to the economy.
I’ve just come from the UK, and while rules were less strict for a while, and people weren’t wearing masks as much, I’m less certain if people were social distancing. We certainly were in preparation for travel, but I imagine schools, college holidays, etc contributed just as much as any variant.
The title requires context - although given recent events we can infer that it is referring to the specific mutation seen in the UK. This particular mutation is of note since it has postulated as being more transmissible than other variants.
