A therapeutic model for the expedient treatment of deadly pathogens involved in pandemics and bioterrorism related events. The immune pathogenesis of deadly pathogens is redefined in the light of Recent advances in the Fundamentals of Immunology by developing three dimensional understandings of deadly pathogens and its interactions with host and its immune system. The immune pathogenesis of deadly pathogens can be treated expediently and globally with NSPS to mitigate the threat of bioterrorism and pandemics. According to a method for treating deadly pathogens having an immune regulatory molecule, the first step is providing a nano-engineered formulation of sodium polystyrene sulfonate (NSPS) having particle size less than 100 nm. A pharmaceutically effective dose of the NSPS is administered to a patient infected with the pathogen. The immune regulatory molecule is targeted with the NSPS for inhibiting serine protease activation. The therapeutic model is further extended for quarantine purposes to facilitate decontamination measures for patients, hospitals and laboratories.
