Kinetics of antibody response to Coxiella burnetii infection (Q fever): Estimation of the seroresponse onset from antibody levels

Highlights • The study provides insight into the dynamics of a Coxiella burnetii infection. • Analysing antibody response kinetics enables estimation of the seroresponse onset. • The time to onset seroresponse is extremely variable among individuals. • Acute and past-resolved Q fever can be distinguished in post-epidemic/endemic areas. • The tool can estimate the Q fever outbreak/epidemic onset based on serologic data.
