The infection increased in the numbers of CD3<sup>+</sup> T cells, including CD4<sup>+</sup> and CD8<sup>+</sup> T, CD4<sup>+</sup> central memory T (Tcm), CD4<sup>+</sup> effector memory T (Tem), CD8<sup>+</sup> Tcm, CD8<sup>+</sup> Tem, CD8<sup>+</sup> virtual memory T (Tvm), CD8<sup>+</sup> short-lived effector cells (SLEC), and CD8<sup>+</sup> memory precursor effector cells (CD8<sup>+</sup> MPEC) in peripheral blood. This evidence concerns the gene CD4 and infection.
