SHARE The Covid-19 pandemic raised new fears for counter-terrorism experts: a virus just as devastating could be deliberately unleashed on the world. There is a scenario in which they use a war-game drill as a basis for emergency planning. In the exercise, money is paid to rogue scientists to use a level three biosecurity laboratory to develop a synthetically manipulated pathogen that is highly contaminating but low in toxicity, similar to Covid-19. Using the equivalent of a suicide bomber, the terrorists inject the pathogen into three victims around the Easter holidays. One goes to a refugee camp where it is passed on to aid workers who later fly to their various home countries.
