No significant difference was observed among these groups (p > 0.1) (Figure 6C), demonstrating that the CCHFV-LISA did not detect IgG antibodies from the sera of patients with Chikungunya, dengue fever, or hepatitis C. Taken together, the NP-C2 fragment corresponding to the stalk structure exhibited good specificity. The gene discussed is C2; the disease is dengue disease.
