    Snippet: Whether or not these CD34 Ï© cells are also the major target for SARS-CoV in the early phase of infection remains to be investigated. Our ex vivo infection model in part can be a complement to actual early infection. However, in vivo confi rmation of the identity of virus-targeted cells in the early phase is diffi cult because of unavailability of samples from patients who died within 3 d after illness onset or even before the onset. Extrapolatio.....
    Document: Whether or not these CD34 Ï© cells are also the major target for SARS-CoV in the early phase of infection remains to be investigated. Our ex vivo infection model in part can be a complement to actual early infection. However, in vivo confi rmation of the identity of virus-targeted cells in the early phase is diffi cult because of unavailability of samples from patients who died within 3 d after illness onset or even before the onset. Extrapolation of animal studies to humans for early infection also requires much caution because iatrogenic inoculation with large-volume viral droplets into animals is different from infection in a more natural aerosol form in human settings ( 30 ) . Moreover, the value and reproducibility of the nonhuman primate model for SARS infection are also highly disputable ( 31, 32 ) .
