Actually, not zero but very, very little danger to black people… “The study—a preprint that has not yet been peer-reviewed—is entitled Single-cell RNA expression profiling of ACE2, the putative receptor of Wuhan 2019-nCov, By Yu Zhao et al., bioRxiv, 2020] and is authored by a group of medical scientists based at Tongji University in Shanghai
“The authors explain that “2019-nCov was reported to share the same receptor, Angiotensin-converting enzyme 2 (ACE2)” as the SARS disease, an outbreak of which in 2003 seemed almost exclusively to kill Northeast Asians”
“Based on “the public database and the state-of-the-art single-cell RNA-Seq technique” the Chinese scientists “analyzed the ACE2 RNA expression profile in the normal human lungs.” Crucially, they further found (in a comparison of eight individual samples) that the “Asian male one has an extremely large number of ACE2-expressing cells in the lung” in comparison to other races. (The database was based on analysis of eight normal human lung transplant donors of different races.)
“As they put it:
“We also noticed that the only Asian donor (male) has a much higher ACE2-expressing cell ratio than white and African American donors (2.50% vs. 0.47% of all cells). This might explain the observation that the new Coronavirus pandemic and previous SARS-Cov pandemic are concentrated in the Asian area.”
