Abstract
The purpose of this paper is to outline the features of combating emerging
infectious disease in occupational fields and the discussion about the Act on the
Prevention of Infectious Diseases (IfSG) in Germany, especially the duty to give
proof of having immunity to Covid-19 relevant to employees working at particular
facilities and companies. From the consideration of German law, the following
suggestions were obtained regarding the measures of preventing an emerging
infectious disease in Japan. First, vaccination duty can be justified according to the
risks if people have an infection. Second, public organizations are to be involved
in the measures of preventing an emerging infectious disease in occupational field.
Finally, we have to consider what effect the obligations under public law have on
the labor contract relationship.
