Enhancing Preparedness against Rubella at the Workplace: Proactive Prevention Efforts by the Tokyo Metropolitan Government.

In the 2012-2013 rubella epidemic in Japan, most transmissions in Tokyo occurred at workplaces, especially among men aged 20-49 years. This tendency was likely related to previous rubella immunization policies that prioritized female adolescents. Since 2015, the Tokyo Metropolitan Government has been promoting a project to prevent rubella and other infectious diseases in workplaces. Companies participate by choosing one or more of three options: (i) acquire fundamental understanding of infectious diseases, (ii) develop a Business Continuity Plan (BCP) for infectious diseases in the workplace, and (iii) increase rubella antibody prevalence in employees.Criteria for accomplishment are (i) at least 80% of employees complete the infectious disease training modules or (ii) produce a BCP and (iii) at least 90% of employees demonstrate the presence of antibodies at levels sufficient for preventing rubella. As of July 2018, 39.8% (n ＝ 90) of the 226 companies that began participating in 2015-2017 had met at least one accomplishment criteria (Option I, 42.7% of 192 companies; Option II, 19.3% of 140; and Option III, 17.0% of 53). The main project challenges were recruiting companies and following participating companies. Although early in its implementation, this project has made considerable contributions toward rubella elimination in Japan.
