Survival analysis and clinical score of WNV NY99 and WNV Eg101 infected mice. a Eight-week-old C57BL/6J mice were inoculated subcutaneously with 100 PFU of WNV NY99 or WNV Eg101. All mice were observed for 21 days. Data are combined of three independent studies (n = 24 mice per group). b Animals were monitored for clinical scores twice a day. The designation for the clinical scores is as follows: 1, ruffled fur/hunched back; 2, paresis/difficulty walking; 3, paralysis; 4, moribund/euthanized; and 5, dead. Error bars represent SEM. *p < 0.001, **p < 0.0001
