Unrecognised underlying condition for COVID-19: perspective study of meridian and M-shaped male baldness

Male androgenetic alopecia (MAA) is observed as a high severity risk factor but not listed within underlying COVID-19 conditionsdue to scanty available evidence. From a Chinese medicine (CM) perspective, the pathogenesis of MAA is overlapping with many recognised underlying conditions. This article compares CM meridian theory with MAA pattern progression to illustrate 1) the morphological and topographical superposition between the MAA progressing pattern and CM meridians, 2) damp-heat dominated body constitution presences among MAA patients as well as some underlying COVID-19 conditions, 3) vulnerable body type should be alerted and recognised to avoid an increase in infectious severity rate. The fundamental acupuncture points of treatment are provided for a concrete clarification of MAA.
