A new study from China has explained why the Delta variant has spread so quickly throughout the world. Put simply, it’s because the Covid variant makes copies of itself more quickly in the body and causes symptoms to appear sooner than previous mutant strains.
In the US, the variant took COVID cases from 10% in June to 83.2% of all new infections by mid-July.
As well, patients infected with the Delta mutation had a ‘viral load that was 1,000 times higher,’ meaning they had 1,000 times as many copies in their respiratory tracts as, people infected with the original strain.
Scary.
