Over the last decades there have been about thirty newly
          
        
        
          
            emerging diseases that had the potential to be pandemics.
          
        
        
          
            It’s not a matter of if there will be a global pandemic, it’s
          
        
        
          
            just a matter of when and which virus and how bad.

            We’re more vulnerable [to infectious diseases] because
          
        
        
          
            of our mobility. We’re also living more and more in
          
        
        
          
            crowded cities. That’s fantastic from the perspective
          
        
        
          
            of a virus because in no time it can infect hundreds of
          
        
        
          
            thousands of people.
