Prevention and Control of Communicable Diseases


Parapertussis

Parapertussis is similar to pertussis but tends to be a milder disease than pertussis.

Cause

Bordetella parapertussis bacteria.

Symptoms

Parapertussis begins with a runny nose, sneezing, mild cough, and possibly a low- grade fever. The cough may occur in sudden, uncontrollable bursts, sometimes ending with high-pitched whooping sounds and/or vomiting.

Spread

When a person with parapertussis coughs tiny droplets with parapertussis bacteria into the air and another person breathes them in.

Incubation

It takes from 6 to 21 days, usually 7 to 10 days from the time a person is exposed until symptoms start.

Contagious Period

Unknown, but probably most infectious at the time of early cold-like symptoms.

Exclusion

Child Care and School: None, if the child is well enough to participate in routine activities.

Diagnosis

To confirm a diagnosis of parapertussis, laboratory tests are performed on material collected by placing a flexible swab through the nostril to the back of the nose and throat.

Treatment

Persons with parapertussis can be treated with antibiotics, but antibiotics may do little to lessen the symptoms. Treatment is most effective if started soon after cough begins.

Prevention/Control

  • Cover your nose and mouth with a tissue when coughing or sneezing, or cough/sneeze into your sleeve. Dispose of used tissues.
  • Regular and thorough handwashing is the best way to prevent spread of communicable diseases. Wash hands thoroughly with soap and warm running water after contact with secretions from the nose or mouth.
  • Preventive treatment is not generally recommended for contacts of people with parapertussis. Preventive treatment may be considered for close contacts who are at a higher risk for more severe disease, including infants and immuno- compromised persons. Vaccines for pertussis (DTaP and Tdap) are not effective against parapertussis.
  • Clean and sanitize mouthed objects, and surfaces at least daily and when soiled.
