“…Of the 36 samples, we found 18 with detectable neutralizing antibodies to CHIKV (2/17 from the IgM+IgG− subgroup and 16/19 from the IgM+IgG+ subgroup) ( Table 1 , Figure 2a ). The lack of neutralizing antibodies in participants from the CHIKV IgM+IgG− subgroup (15/17) was unexpected, but was in agreement with the observation of five distinct antibody patterns and the presence of an IgM+IgG− period in some individuals based on the study of 133 samples following acute CHIKV infection [ 23 ].…”

“…After CHIKV infection, individuals develop an IgM response starting from 3 to 8 days post-symptom onset, followed by an IgG response at 7 to 14 days [ 25 ]. A recent study reported five distinct antibody patterns (IgM−IgG−/NT−, IgM+IgG−/NT−, IgM+IgG−/NT+, IgM+IgG+/NT− and IgM+IgG+/NT+) during acute febrile phase and the presence of NT or IgG antibody was associated with protection against developing chronic arthritis in the future, which was supported by two studies of outbreaks in India (2010–3 and 2014–6) [ 23 , 26 ]. Although most individuals of the IgM−IgG− and IgM+ IgG− subgroups developed IgG and NT antibodies at the convalescent-phase, this may explain some IgM+IgG− and NT− samples observed in our study.…”

“…8 On the contrary, induction of IgG1 and IgG2 in acute-phase plasma samples with negligible IgG3 and no IgG4 was found when screened with CHIKV. 9 Taken together, when CHIKV was used for ELISA, both Indian studies identified IgG1 (Nayak et al 9 and present study), although IgG2 and IgG4 subtype detection rates did vary; IgG3 was the predominant serotype with envelope protein peptides. 8 The possibility of unavailability of IgG3 reactive peptide epitopes on the surface of the virus cannot be ruled out.…”

“…8 Contrary to these finding, IgG1 and IgG2 antibodies were detected in acutephase serum samples with negligible IgG3 and no IgG4. 9 It is well reported that antiviral activity (virus neutralization and clearance) is associated with IgG1 and IgG3 subtypes that bind to all human Fc-gamma receptors (FcγR) classes and target antigen to phagocytosis. 10 Both these antibodies are elicited against protein antigens and are outcome of Th1 response.…”

“…The antibody response patterns might vary between mono-infected and co-infected patients. Hence, it is very important to determine the mono-infection and coinfection status of the patients as the antibodies patterns generated in response to the infection might serve as biomarkers for disease progression (Nayak et al, 2020).…”
