Delayed immune responses may drive COVID-19 mortality rates among men and the elderly

(PLOS) COVID-19 (SARS-CoV-2) infections tend to be more severe among older adults and males, yet the mechanisms underlying increased mortality in these two demographics are unknown. A study published in the open access journal PLOS Biology on September 8, 2020 by Nicole Lieberman and Alexander Greninger at University of Washington and colleagues suggests that varying immune responses to SARS-CoV-2 due to age and sex may depend on viral load and the time-course of infection.
