The convalescent stage often lasts 2 to 6 weeks but in some cases it may last up to 3 months. Pertussis infection may be detected via culture, direct fluorescent antibody testing, serologic testing, and molecular testing by PCR methods. 6-week disease divided into catarrhal, paroxysmal, and convalescent stages, each lasting from 1-2 weeks Stages of disease Stage 1 : The initial (catarrhal) phase is indistinguishable from common upper respiratory infections with nasal congestion, rhinorrhea, and sneezing, variably accompanied by low-grade fever, tearing, and conjunctival suffusion.
