text: The**COVID-19 pandemic**made the public aware of the powerful impact of these risks, and also of the 
  high risks of infections in some occupations. During the pandemic, the above-mentioned list of 
  workplaces with well-known risks from biological agents was significantly extended; practically all 
  workplaces with direct human–human communication were included, for example, workers in education, 
  workers in public transport, sales and restaurant personnel and so on. 
  
  During the pandemic preventive measures for workplaces were introduced that**might change future**
  **prevention**practices towards biological agents, for example, the obligation to wear PPE might be 
  applied for**many more worker groups and for more circumstances**, more rules for the organisation 
  of personal contacts and communication at work have been developed and tested in practice, stronger 
  ventilation might be implemented, and the measures might include a significantly higher use of 
  disinfecting chemicals. The future development — be it regional or national outbreaks or worldwide 
  pandemics — is unforeseeable. The connections between global societies due to international supply 
  and transport chains and tourism will definitely increase the risk of future worldwide pandemics.
