Infants most at risk when whooping cough spreads, public health doctor says

Whooping cough spreads easily and is especially dangerous for infants, so getting an outbreak under control is important, says Dr. Yves Lger, the medical health officer in eastern New Brunswick.

Whooping cough spreads easily and is especially dangerous for infants, so getting an outbreak under control is important, says Dr. YvesLger, the medical health officer in eastern New Brunswick.

An outbreak of whooping cough, a respiratory infection also known as pertussis,was recently declared atMonctonHigh School after five cases were diagnosed.

Parents learned the news in a letter sent byLger,datedMarch 1, just before students went on March break.

He said the main reason to control thespread ofpertussisisto protect young infants, who can die from it.

"It's a bacteria that spreads quite easily from one person to another especially whenwe have symptoms," he said in an interview.

Don't ignore symptoms

Lger said the letter sent to parents of Moncton High School students conveyed the main message he wanted to get out.

"If you have symptoms ofpertussis, if you're coughing, get assessed."

The test for pertussis is simple, and the results come back fairly quickly, he said

Once treated with antibiotics, a person with whooping cough is no longer contagious.

Lgersaid symptoms in an adult include a cough that can linger for weeks or even months.

For younger children and teenagers,pertussisstarts out like a cold but after a week or two, the cough worsens.

"Then you start having fits of coughs," Lgersaid. "So you start coughing non-stop until you're out of breath. Then that is often followed by a whoop, or a high pitched noise that people make when they are catching their breath."

Lgersaid can occur over several weeks to a month.

March Break delays clinic

Because of the March Break, the Health Department delayed a clinic to give the booster dose to those who hadn't received theirs.

"That weekdefinitelyputs us back a little bit in terms of being able to hold that clinic."

But the break may help stop or slow down the spread of the disease, he said, "so that may be a positive in one sense."

Statistics from the Department of Heath show 25 to 30 per cent of the Moncton High School population didn't receive the booster shot for pertussis that's offered through a school-based program for Grade 7 students.

Those students can be immunized at a school clinic being held March 20, two weeks after students return from their break.

Bacteria follow cyclical pattern

While students in New Brunswick have to show proof of immunization before they enter school for kindergarten, no proof is required when students enter high school, he said.

Asked if this should be considered as a requirement, the medical officersaid it could be, but he also wants to encourage people to get their vaccines.

The disease appears to follow a cyclical pattern,Lgersaid

"It tends to go up and down with times. Every three to five years, we tend to see increases inpertussisactivity."
