COVID‐19 and primary wound healing: A new insights and advance.

With the outbreak and pandemic of coronavirus disease‐2019 (COVID‐19), a huge number of people died of it. Apart from lung injuries, multiple organs have been confirmed to be impaired. In COVID‐19 time, primary wound healing processes always prolong, however, its possible underlying mechanisms are still unclear. Therefore, to overcome this clinical problem, clarifying its underlying mechanisms clearly is necessary and urgently needed. In this review, we summarized that COVID‐19 can prolong primary wound healing by inducing excessive inflammation and oxidative stress, disturbing immune system and haematological system, as well as influencing the functions and viability of epidermal stem cells (ESCs). Otherwise, we summarized that the strict control measures of blocking up COVID‐19 pandemic can also have side effects on primary wound healing process. [ABSTRACT FROM AUTHOR]
