The Idea behind this manga is innovative but it doesn't have any depth, this is not really reflecting on how a world with a permanent pandemic type virus would be, you can say that the current situation is a good indication but remember masks and social distancing are only a temporary preventive measure till the vaccine arrives, for permanent case of a pandemic type virus would be more serious, like makes can't be removed in streets due to locking features or like you have to wear a spacesuit outside and only homes will be completely sanitised where you can be outside your suits etc. This looks like the Godzilla movie, where ymthe dad of the protag goes to the danger zone in Japan and suddenly finds out the air is clean . Lazy writing.
