Why esr is decreased in whooping cough?

Answer 1

Erythrocyte sedimentation rate (ESR) is often decreased in whooping cough (caused by Bordetella pertussis) due to the nature of the immune response and inflammation associated with the infection. In whooping cough, the body primarily produces a specific immune response characterized by lymphocytic infiltration rather than the more generalized inflammation that typically raises ESR. Additionally, the presence of specific antibodies and the nature of the infection can lead to a lower ESR reading. Thus, while ESR can be a marker of inflammation, its decrease in this context reflects the unique immunological response to whooping cough.
