The difference between the third wave and the second wave is the Corona Virus November 17 at 7:32 p.m.
Since this month, the rate of infection of the new coronavirus has been rapidly spreading not only in large urban areas such as Tokyo, but also in areas where temperatures have dropped, such as Hokkaido, and it is said that it is the third wave of infection.
The number of new and severe cases exceeded the peak of the second wave of infection that spread in the summer. Compared to the second wave of infection, there is a tendency to increase the proportion of elderly people at high risk of becoming severe, and as clusters are diversifying and it is becoming more difficult for the government to respond, experts are calling for thorough basic infection measures once again.
[New infected persons nationwide]above the peak of the second wave
In the second wave of infection, which has spread from Tokyo since the beginning of July, the number of new infections nationwide peaked at 1605 on August 7 and above 1300 on average per week at that time.
On the other hand, the spread of the infection earlier this month has already exceeded the peak of the second wave, with more than 500 people infected until late October, 1736 on the 14th of this month in about half a month, and about 1,400 on average per week.
Percentage by age: Over 60s more than double the second wave
In addition, the proportion of people in their 60s and those in their 60s who are said to be more likely to become severe in the proportion of infected people by age tends to be higher than that of the second wave.
For example, in Tokyo, in July, when the number of infected people increased rapidly in the second wave,
4.6% of teens and below
43.1% of people in their 20s
24.0% in their 30s and 70% or more in their 30s and below.
12.7% in their 40s
7.5% in their 50s
The number of people in their 60s and older was 8.2%, and the number of elderly people was relatively small.
On the other hand, this month is up to the 16th.
7.7% of teens and below
25.3% of people in their 20s
The number of people in their 30s decreased to 19.8%, and the number of people in their 30s and below decreased by about half.
16.5% in their 40s
13.6% in their 50s
The proportion of people in their 60s and above is 17.1%, more than double that of the second wave, especially 60s and above.
A similar trend in Osaka Prefecture is that the proportion of people in their 60s and eries was 9.5% in July, whereas this month it was 25.8%.
[Hospital and recuperation]12,358 people on the 15th of this month
On the other hand, the number of people hospitalized and recuperating increased sharply in the second wave from about 700 in late June to 13,724 on August 10, nearly 20 times in a little over a month.
After that, the number gradually decreased to about 5,000 in late October, but the infection spread without decreasing enough, to 12,358 on the 15th of this month.
[Severe person]exceeds the peak of the second wave
In the second wave, the number of severe patients decreased to 131 on October 5, less than two weeks after the peak of infected people, to 259 on August 24, but the infection spread and reached 272 on the 17th, exceeding the peak of the second wave.
[Death toll]a lot more than 10 people this month
In addition, the number of deaths was less than 10 after 16 people were reported on August 18 and 20 on August 28 in the second wave, but since the start of this month, there have been more than 10 people, such as 15 on the 10th.
Expert “Cluster diversification: Continuation of basic measures”
In addition, according to the expert meeting of the Ministry of Health, Labour and Welfare, the group of infected people in the second wave, while there were many restaurants with entertainment in metropolitan areas and meetings in the workplace, from this month onward, in addition to dinners and workplaces, local entertainment districts and foreign communities, as well as medical institutions and welfare facilities, it is said that spread to the region.
Professor Ihiro Shibata of Toho University, president of the Infectious Diseases Society of Japan, said, “In the second wave, the spread of infection was limited to specific areas, and we were able to respond by targeting, but in the third wave, clusters are diversifying and it is becoming difficult to respond. In the future, there is a possibility that it will develop into a larger cluster by involving medical institutions and facilities for the elderly.”
On top of that, he said, “It seems that some people have been tired or relaxed as the infection continues, but it is necessary for each person to take action to avoid the risk of infection again. 3 Avoid tightness and continue basic measures such as wearing, disinfecting, and ventilating masks.”
