Low counts of both CD4 + and CD8 + cells in the peripheral circulation do not always indicate that the immune system is impaired: redistribution of lymphocytes among peripheral and secondary lymphoid organs and migration of these cells to inflamed tissues caused by infections may also result in lymphopenia. We believe that Zhou and Chen [1] need more data to support their conclusion that the immune function of B cells in our patients appeared not to be impaired because specific anti-SARS-CoV could be detected as early as 10 days after the onset of illness.
