Pertussis is actually increasing in frequency of occurance again. I always thought I was protected because I was vaccinated when I was younger. They have now found that that isn't the case. That is why they now have second vaccines for children and the adult vaccines.
I got Pertussis (Whooping Cough) a couple years ago. Ironically I was treated with the antibiotics for a chronic sinus infection before the Pertussis was diangosed so there wasn't really anything more they could do for me after I was diagnosed.
Whooping cough is call the 100 days cough. It takes a long time to run its course. It wore my body down so much that I actually picked up a couple other things at the same time. It was a loooong 4 months.
My experience with Whooping Cough involved a chronic dry cough that was constant. I would cough so hard that I couldn't catch my breath, my stomach muscles and ribs hurt and sometimes I actually vomited. It didn't have a 'whooping' sound. It isn't usually present in adults. It is just a constant horrible experience. It is awful when you can't breathe. When I first got it, they thought my sinus infection had flared my asthma. I was treated for those until they realized that in addition to the sinus infection and asthma flare-up, I had also developed the Pertussis. They did a blood test first. It came back inconclusive which sometimes happens because of previous vaccines. I then had a special nasal swab test (with a very long swab). This test came back positive. As I said before, I had already received the antibiotics so additional treatment wasn't needed. Cough medicines really didn't work. I did take some codeine meds at one time just because I couldn't get much sleep due to the coughing. Towards the end of the 4 months, the coughing started to taper and it eventually died away.
After being diagnosed, I received a call from the Health Department. This is one of the diseases that they are required to track.
By the way, I had this when I was 36. I've had no reprecutions from having had this.
