6/29/2021 Dr. Quay and Dr. Muller: A natural zoonosis takes a year to 18 months to learn how to infect humans, but the Covid-19 was human to human transmissible from the get-go, which simply indicates a gain of function. China initially said the virus came from animals. But scientists found 0 out of 80,000 animals. The humanized mice in the Wuhan Institute of virology was never examined. Covid-19 could only be in the lab, not from nature.
