I suspect we have some measurement bias in this chart, as liver cirrhosis takes more than 2 years to present, but...we can also note that science indicates that sugar is a significant cause of liver damage. We can theorize that "lock down" has increased both alcohol and sugar consumption. Also dramatic increases in watching Netflix and Prime Video as well as conventional "news" media - and there is a definite link between watching a lot of news media and accelerated brain death ;-).
