Contact confirmation app "COCOA" again trouble Cause investigation by MHLW August 6 21:23

The Ministry of Health, Labor and Welfare is investigating the cause of the problem found in the "contact confirmation app" that allows you to be notified if you suspect you have made a heavy contact with a person infected with the new coronavirus.

In the contact confirmation application "COCOA", the data of users who have stayed for more than 15 minutes within 1 meter is recorded, and when a user who is found to be infected enters the processing number issued by the public health center, it notifies the other person.

However, according to the Ministry of Health, Labor and Welfare, since the last week, people who received the notification have received multiple contacts saying "When opening the application, "No contact was confirmed" was displayed."

Initially, the Ministry of Health, Labor and Welfare explained to the inquiry that the notification was incorrect, but this week it was notified that "the content displayed in the application may be incorrect". We encourage people to contact us by e-mail on our website.

Regarding this app, malfunctions have been frequently confirmed since the Ministry of Health, Labor and Welfare started operation in June.

As of the 5th day, about 11.57 million items have been downloaded, so a person in charge of the Ministry of Health, Labor and Welfare said, "I want to immediately check the cause of the defect and correct it."
