Nasal spray prevention shifts pandemic defense from treatment to respiratory intervention

Ewaisha argues that viral pandemic prevention is shifting from systemic treatments and vaccines toward targeted, non-invasive respiratory interventions—specifically nasal sprays that block viral entry points in the respiratory system. This represents a fundamental change in public health strategy: preventing infection at the anatomical site of viral transmission rather than managing disease after systemic exposure.
