Pertussis (Whooping cough)
What is pertussis?
Pertussis (whooping cough) causes violent coughing that may last for months. During
coughing episodes, people may make a “whooping” sound when they try to inhale. Most people recover from whooping cough with no problems, but it can be dangerous in young
children, especially babies, and the elderly.
Cause:
Bordetella pertussis bacteria
Transmission:
Direct contact with fluids or airborne droplets that are inhaled.
Symptoms:
Symptoms can range from mild to severe. Hear what it sounds like in a child and in an adult. Symptoms usually appear 7-14 days after infection. Symptoms usually last 6-10 weeks but may last longer. Symptoms may occur in three stages, especially in young children. Others may not follow this pattern of symptoms.
In stage 1, symptoms are cold-like:
- Sneezing, runny nose, a mild cough, watery eyes, and sometimes a mild fever
- Symptoms last from several days to 2 weeks
- This is when the disease is most easily transmitted
In stage 2, cold symptoms get better but coughing gets worse.
- The cough goes from a mild, dry, hacking cough to a severe cough.
- People may cough so long and hard that they can’t breathe, and make a whooping noise when trying to inhale.
- After a coughing fit, people may vomit and feel very tired. Between coughing fits, people feel normal.
- Symptoms are most severe in this stage, and usually last 2-4 weeks or longer.
In stage 3, symptoms continue, but people feel better and grow stronger.
- The cough may get louder.
- Coughing fits may happen off and on for weeks.
- Coughing fits may flare up if people get a cold or have a similar illness.
- This stage may last longer if people have never had the vaccine.
Diagnosis:
Diagnosis may be difficult, because people may seem healthy between coughing episodes. Health care providers can perform a variety of tests to properly diagnose.
Treatment:
Pertussis is usually treated with antibiotics, which reduces duration of illness and
transmission to others.
Adults or teens with pertussis need to take antibiotics for at least 5 days before returning to work or school to prevent transmission to others.
To help reduce coughing:
- Create a quiet, calm and restful environment
- Control triggers of coughing such as smoke, dust and temperature changes.
- Drink plenty of water and other hydrating fluids.
- Over-the-counter medicines such as cough syrups don’t help,
Prevention:
- Get vaccinated. Vaccination reduces risk of infection, make it less severe, and prevents transmission.
- People with close contact with someone with pertussis may be prescribed antibiotics to prevent infection.
- Wash your hands often.
- Cover coughs and sneezes with a tissue or your arm. Don’t cough into your hand because that can spread germs.
- Avoid contact with people who have a bad cough.
