Whooping cough outbreak worsening in southern Alberta

Feb 8, 2023 | 3:35 PM

LETHBRIDGE, AB – Alberta Health Services is asking the public to be careful as the number of cases of pertussis (whooping cough) in southern Alberta continues to grow.

An outbreak was declared on Jan. 26, in the communities of Lethbridge County, Coaldale, Taber, Vauxhall, Grassy Lake and Bow Island. According to AHS, these areas have particularly low rates of immunization.

As of Feb. 8, the number of cases has more than doubled from 16 to 39.

AHS says in a media release, “There is no evidence of spread outside the South Zone.”

Officials with AHS add that pertussis is a bacterial infection that causes severe and prolonged coughing that lasts for weeks.

While people of all ages can contract it, people under the age of one year are at the greatest risk of serious complications including pneumonia, convulsions, brain damage, and death.

AHS says, “Pertussis illness starts with a runny nose, sneezing, fever, and mild cough. Typically, over the duration of a week, the cough will become more severe with repetitive coughing spells. In younger children, these coughing spells are usually followed by a ‘whooping’ sound when inhaling. Vomiting following a coughing spell is also common.”

The health agency reminds the public that immunization is the best method to protect against and limit the spread of pertussis, along with regular hand washing and not sharing drinks, food, or cutlery.

Immunization information for pertussis can be found on the AHS website.
