Whooping Cough or Pertussis

April 4th, 2013

Dear TCA Families,

We have a suspected case of pertussis in our school. Please be aware of excessive coughing and take your children to a physician for confirmation. Anyone with a suspected or confirmed case of Pertuss (Whooping Cough) may not return to school until at least five (5) days after antibiotic treatment begins.

Symptoms

Pertussis (whooping cough) can cause serious illness in infants, children and adults. The disease usually starts with cold-like symptoms and maybe a mild cough or fever. After 1 to 2 weeks, severe coughing can begin. Unlike the common cold, pertussis can become a series of coughing fits that continues for weeks.

In infants, the cough can be minimal or not even there. Infants may have a symptom known as “apnea.” Apnea is a pause in the child’s breathing pattern. Pertussis is most dangerous for babies. More than half of infants younger than 1 year of age who get the disease must be hospitalized.

Pertussis can cause violent and rapid coughing, over and over, until the air is gone from the lungs and you are forced to inhale with a loud “whooping” sound. This extreme coughing can cause you to throw up and be very tired. The “whoop” is often not there and the infection is generally milder (less severe) in teens and adults, especially those who have been vaccinated.

Early symptoms can last for 1 to 2 weeks and usually include:

Runny nose
Low-grade fever (generally minimal throughout the course of the disease)
Mild, occasional cough
Apnea – a pause in breathing (in infants)
Because pertussis in its early stages appears to be nothing more than the common cold, it is often not suspected or diagnosed until the more severe symptoms appear. Infected people are most contagious during this time, up to about 2 weeks after the cough begins. Antibiotics may shorten the amount of time someone is contagious.

As the disease progresses, the traditional symptoms of pertussis appear and include:

Paroxysms (fits) of many, rapid coughs followed by a high-pitched “whoop”
Vomiting (throwing up)
Exhaustion (very tired) after coughing fits

The coughing fits can go on for up to 10 weeks or more. In China, pertussis is known as the “100 day cough.”

Although you are often exhausted after a coughing fit, you usually appear fairly well in-between. Coughing fits generally become more common and severe as the illness continues, and can occur more often at night. The illness can be milder (less severe) and the typical “whoop” absent in children, teens, and adults who have been vaccinated.

Recovery from pertussis can happen slowly. The cough becomes less severe and less common. However, coughing fits can return with other respiratory infections for many months after pertussis started.

School Exclusion

Children with suspected or confirmed pertussis should be kept out of school or childcare until they have completed five (5) days of antibiotic therapy. Rules for exclusion of sick children from school and childcare are outlined in the Texas Administrative Code, specifically Rule 97.7 for schools and Rule 746.3603 for childcare.
