2 cases of whooping cough reported in Yukon

Health officials are advising Yukon residentsto watch for signs and symptoms of pertussis better known as whooping cough after two unrelated cases were recently confirmed in the territory.

Dr. Brendan Hanley, the territory'sChief Medical Officer of Health, says that the last outbreak of whooping cough was three years ago, but more cases are being reported than usual.

"We're seeing pertussis a little bit more frequently in the last few years, and I don't know if that's understood why that should be the case," he says. "It seems that we have a relatively susceptible population."

Hanley notes there have been outbreaks in other parts of Canada in recent years.

Early symptoms of pertussis are similar to those of a common cold: a runny nose, sneezing, a lowfever;and a mild cough. The caugh can then become severe enough to cause breathing problems, or make people gag and throw up, and symptoms can persist for up to 12 weeks.

One to three people in Canada die from pertussis every year usually infants who are under-immunized.

Hanley says pertussis is a vaccine-preventable diseaseand getting immunized is the best way to protect yourself. In a press release, the Yukon government says that anyone unsure of their immunization status can contact the Whitehorse Health Centre, or their community health centre.

Vaccine effective, says doctor

Hanley says the vaccine is effective when widely used.

"There's definitely a protective effectfromvaccination but it's not 100 per cent. The more a community is immunizedthe more the community is protected," he says.

Whileimmunized individuals can stillget the infection, Hanley saysthis is far less likely.

"It's important that school children are up-to-date with theirimmunizationsand adults should alsoreceivea dose ofpertussisimmunization," he says.

Hanleysays Yukon does notrecommendrepeated immunizations as health authorities believe one dose provides enough protection.

"If we could justassurethat enough adults had just one dose, that would certainly help to protect the community.Especiallyin those households that have young infants or pregnant women. It's helpful for that whole family to be up to date with immunizations," he says.

He adds the typical adult or teenager who contracts whooping cough will have a "veryprolongedhacking cough" that can keep themawakeat night, while symptoms for younger children can include vomiting and a loudtype of raspy laboured breathingthat gives whoopingcough its name.
