Inactivation of ZIKV by gamma irradiation of three virus titers: 1 × 105 PFU/mL, 1 × 106 PFU/mL and 1 × 107 PFU/mL was screened at gamma irradiation doses between 1 Mrad and 6 Mrad. Y: inactivation was successful (no CPE and no plaques); N: inactivation failed (positive for CPE or plaque formation).
