According to the Ministry of Health, Labor and Welfare, the rate of death and case fatality rate of people infected with the new coronavirus was actually high when there were risk factors that were likely to become severe, such as nearly 14% for people with chronic kidney disease. I summarized it.
The case fatality rate was higher as there were more factors.
The Ministry of Health, Labor and Welfare has been known for kidney disease and diabetes among the 320,000 infected people registered in the three months from April on the system "HER-SYS" that aggregates information on infected people. We analyzed the case fatality rates of more than 100,000 people who were noted to have nine risk factors for aggravation.
As a result, the case fatality rate was 0.41% for those who did not have a risk factor for aggravation, but it was 2.28% for those who did, which was more than five times higher.
By factor, ▽ chronic kidney disease 13.95%, ▽ COPD = chronic obstructive pulmonary disease 10.19%, ▽ cancer 8.35%, ▽ immunosuppression 7.54%, ▽ diabetes 4.76%, ▽ hypertension Was 4.32%, ▽ dyslipidemia was 3.30%, ▽ obesity was 1.55%, and ▽ smoking was 0.99%.
The case fatality rate was 1.38% for those who had one factor, 3.80% for two, 5.20% for three, and 9.69% for four or more.
On the other hand, the percentage of elderly people aged 65 and over was 4.62% even if there was no one.
The Ministry of Health, Labor and Welfare wants the data to be used for who is treated in the intensive care unit and for operation in the medical field.
