摘要To the Editor:Following H7N9 infection,the host lymphocyte immunity plays an antiviml role.[1] Furthermore,low frequencies of T-cells correlate with disease severity.[2] Herein,we present a H7N9-infected patient with life-threatening lymphopenia (only 0.06 × 109/L in the peripheral blood),which we have barely ever seen before.We also measured the proportions of T-cell subpopulations in the blood and bronchoalveolar lavage fluid (BALF).
