Countries that have recently taken off masks are wearing them again, and they are poised to get more vaccines. This is because the delta mutation is spreading that fast, and this alone is daunting, but it has been confirmed that another mutant virus first identified in South America has already spread to 29 countries.



For more details, medical reporter Dong-chan Cho will tell you.

Among all mutations in Korea, the delta mutation was the largest at 63%.



Delta was the first to outperform alpha mutations from the UK that led the third pandemic.



The recent momentum is scary, but if you count just last week, 69% of the total mutations, which means that 3 of the total confirmed patients were infected with the delta mutation.

. People in their twenties are most active.



The countermeasure for delta mutations is vaccination.



In a previous UK government study, a two-dose dose had a 70-80% chance of not getting the delta mutation, and a severe prevention rate of over 94%.



However, a recent Canadian study showed that a single dose was more effective than expected, with AstraZeneca and Pfizer 67% and 56%, and severe prevention rates 88% and 78%, respectively.



Among these, a new lambda mutation that appeared in South America was designated as a mutation of interest by the World Health Organization.

last dwaetjiman August first discovered in Peru through a neighboring country Chile, the United States , Germany, UK, Australia, etc. It has already spread rapidly to 29 countries around the world.



What is more worrisome is that Peru, where the lambda mutation has spread, has the highest fatality rate of COVID-19 in the world at 9.3%.



However, although it is in the early stages of research, existing treatments and vaccines have been shown to be effective.
