Pertussis Information

What is Pertussis Disease (Whooping Cough)?

Pertussis, also known as whooping cough, is a highly contagious bacteria respiratory disease.
Pertussis is known for uncontrollable, violent coughing which often makes it hard to breathe.
After coughing fits, someone with pertussis often needs to take deep breaths, which results in a "whooping" sound.
Pertussis can affect people of all ages but can be very serious, even deadly, for babies less than a year old.
Pertussis is a highly contagious disease and can affect up to 80% of household contacts.

Symptoms of pertussis usually develop within 5 to 10 days after you are exposed, but may not develop for as long as 3 weeks.
First week or two, early symptoms may include:
--Subtle onset of runny nose.
--Low-grade fever.
--Sneezing.
--Mild, occasional cough.
--Apnea or stop breathing when asleep.
After 1 to 2 weeks, symptoms may include:
--Fits of many, rapid coughs followed by a high-pitched "whoop" sound.
--Throwing up during or after coughing fits.
--Very tired after coughing fits.

Pertussis is spread from person-to-person.
--Coughing and sneezing.
--Spend a lot of time near one another and share breathing space.
--Some babies get pertussis from older siblings, parents, or caregivers who might not even know they have the disease.
The best prevention for pertussis is the vaccine, but no vaccine is 100% effective.
