WHY THE WINDOW OF OPPORTUNITY?
  • Soviet Program ended before the introduction of
    high end molecular biology
  • Islam has viewed Biological Science as low
    science
  • It is harder than you think the devil is in the
    details

Two Options to Solve HC Crisis
  • REDUCE CARE PROVIDED
  • or
  • TRANSITION TO PRE-SYMPTOMATIC DIAGNOSIS AND
    PREVENTATIVE MEDICINE

The Lack of Effort in Host-Based, Pre-Symptomatic
Detection of Infection is the most CRITICAL
INVESTMENT NEED in our Biodefence Strategy

Medicine Art to Science
Sir William Osler 1892 If it were not for
the great variability among individuals,
medicine might be a science, not an art
Because of our new ability to measure variability
among individuals, medicine now can become a
science rather than an art.
