911 Emergency; Can We Help?

Tracer contacts, for an infectious disease expert, is the day one task to determine the level of infectiousness, and once the secondary attack rate is validated, it is no longer required. 1800 teams of at least five epidemiologists were dispatched in China, and they found an attack rate of less than five percent, four times to low to validate a communicable disease being infected from person to person. You wonder why we blew off tracer contacts after being warned three times to ramp up capabilities in the WHO declaration of a PHEIC on January 31, 2020? Willful blindness.
