I am researching information on pertussis and sarcoid. I have been relatively symptom free for the last few months until I was plagued with a terrible cough that broke and separated ribs several times. I took several rounds of antibiotics and at 8 weeks am still coughing. I had the pertussis antibody test and it came back positive. I had all of my childhood immunizations but have not had an adult Dtap. (Which is now recommended) If any one has any information, studies, links I would be very grateful.
