Influenza(flu) is an epidemic that occurs when the weather is cool and dry. It is a virus that attracts a great deal of attention every year, as it can be very virulent and has a huge impact on society. To prevent the spread of infection, it is important not only to reduce the number of sources of infection, but also to cut off new routes of infection, and Hitachi has developed an "infectious disease forecasting service" that uses AI to predict the degree of prevalence in each region in advance. If you know in advance where the flu is likely to spread, you can take action to prepare for it. The service was born out of the desire of Mr. Tandou, who has three children, to create a system that prevents children from getting the flu. Watch the video to find out how the service is helping to improve people's Quality of Life.
