Dysfunction of adaptive immunity is related to severity of COVID-19: a retrospective study

Abstract

COVID-19 might target adaptive immunity and cause a decrease in lymphocytes, especially T cells and subsets. Physicians should pay close attention to the adaptive immunity of patients upon admission. Monitoring NLR, T lymphocytes, and subsets would help physicians with the proper diagnosis and treatment of COVID-19.<i>The reviews of this paper are available via the supplemental material section.</i>
