This note doesn't exist as an official issue. The People's Bank of China did not produce a "COVID-19" commemorative or emergency banknote. What did circulate widely — and generated significant collector interest — were existing 100 Yuan notes that hospitals and health authorities stamped with ultraviolet-reactive ink warnings urging recipients to sanitize contaminated cash, or that were quarantined and destroyed outright during early 2020 outbreak control measures in Wuhan and surrounding provinces.
If this entry refers to one of those stamped examples, the stamp itself, not the base note, is the collectible element.
