To confirm the contribution of myelomonocytic cells to SFTSV tropism and viral dissemination, groups of C57BL/6 CCR2−/− mice that had their IFN response repressed with anti-IFN antibodies (24-hours prior to infection; PID −1) were inoculated with 105 FFU of wt SFTSV. Here, IFNA1 is linked to infection.
