Corona Virus “Contact Confirmation App” Revised Version Released Ministry of Health, Labour and Welfare September 8, 21:01
About the “contact confirmation app” of the new coronavirus, the Ministry of Health, Labour and Welfare has released a modified version as there is a case that is not notified even if it is likely to have been in deep contact with the infected person.
The contact confirmation app “COCOA” for smartphones records data of users who were within 1 meter for more than 15 minutes, and when one infection is confirmed, it notifys the other party that there is a possibility of thick contact.
However, according to the Ministry of Health, Labour and Welfare, users have pointed out that “there is a high possibility that the family has been infected and in deep contact, but they are not notified.”
On the other hand, there are cases where notifications are received even if the possibility of thick contact such as not going out is low.
For this reason, the Ministry of Health, Labour and Welfare released a modified version of the OS “iOS” for iPhone on August 8 after improving the accuracy of detecting thick contacts.
Android is also scheduled to be released in the near future.
This is the third time that about 16 million COCOAs have been downloaded and fixed so far.
In addition, with regard to COCOA, even if you open the app even if it is displayed on the screen as “may have been in contact with a positive person”, “contact was not confirmed” has also been confirmed, and the Ministry of Health, Labour and Welfare is investigating the cause.
