Question:
How long does it take to get whooping cough (pertussis) test results? My child has a severe cough and is currently being treated for sinusitis. Right before coughing, they take a deep, gasping breath, almost like asthma. The doctor prescribed a bronchodilator patch, and when I apply it, the coughing stops. Can a patch suppress whooping cough symptoms? Also, what medication is typically used to treat whooping cough?
Answer:
I understand you are worried about your child's severe coughing. Here is some information regarding whooping cough (pertussis) testing, symptoms, and treatments.
Whooping Cough Testing
PCR Test (Nasal/Throat Swab): Results usually take 1 to 3 days to come back.
Antibody Test: This can take several days to a week.
If a doctor strongly suspects whooping cough based on clinical symptoms, they may start treatment without a test or before the test results are available.
Whooping Cough vs. Asthma/Cough Patch
Characteristics of Whooping Cough: It typically involves severe, rapid coughing fits followed by a high-pitched "whoop" sound as the child gasps for breath. It can also be accompanied by vomiting.
Effect of the Patch: If the cough significantly improves with a bronchodilator patch (asthma patch), it is actually much more likely that the symptoms are related to asthma or bronchiolitis.
Whooping cough requires antibiotic treatment; a bronchodilator patch alone will not resolve the underlying bacterial infection.
Whooping Cough Treatment
Antibiotics: Typically, antibiotics like Azithromycin (for 5 days) or Clarithromycin (for 7 days) are prescribed.
Early treatment helps reduce contagiousness and may shorten the duration of the symptoms.
Preventative antibiotics may also be considered for family members who have been in close contact.
What You Should Do Now
Explain your child's exact coughing pattern (the gasping sound, the nature of the coughing fits, and whether there is any vomiting) to the pediatrician who is treating their sinusitis.
Discuss with your doctor whether a whooping cough test is necessary.
Seek immediate emergency medical care if your child shows any of the following red flag signs:
Blue or pale lips (cyanosis) or severe difficulty breathing.
Pauses in breathing (apnea) or changes in consciousness after a coughing fit.
Inability to stay hydrated due to frequent vomiting.
Since the patch is effectively controlling the symptoms, it indicates that an asthma-related treatment is working well for your child's current condition. A definitive diagnosis of whooping cough can only be made by a doctor through an in-person evaluation and testing. Continue to observe your child's symptom changes today and make sure to discuss these details at your next pediatric appointment.
