The report on the total number of people infected with the new corona will be reviewed, and from the 26th, the subjects that require detailed reports from medical institutions will be limited nationwide to those who are at high risk of becoming seriously ill.


In order to continue detailed analysis of the speed at which the infection spreads, even as information on infected people with a low risk of developing severe symptoms decreases, we will create a website that asks infected people to enter their symptoms and contact status with other people. , launched by epidemiological researchers.

The website was launched by a group led by Professor Hiroshi Nishiura of Kyoto University for the purpose of analyzing data on the new corona in detail.



Until now, information such as the place of residence, date of onset, and route of infection of all infected people has been reported to the government, and the analysis results have been presented at an expert meeting of the Ministry of Health, Labor and Welfare. It has been pointed out that it will be difficult to analyze in detail, such as the speed at which the infection spreads and the status of the infection in society as a whole, if it is limited to high-risk individuals.



For this reason, the group asks infected people to enter the duration of symptoms such as fever, vaccinations, presence or absence of aftereffects, etc., as well as contact status with other people, and combine it with reports from local governments. , we still want to be able to do further analysis.



In the United States, about 35,000 people registered on a similar website, and it was possible to estimate the infection situation nationwide almost accurately.

Professor Nishiura says, "By inputting each person's data, we will be able to estimate something close to the total number of data, so we would like to ask for your cooperation."
