Pertussis Outbreak

Current Situation: South Zone

A pertussis (whooping cough) outbreak is ongoing in the South Zone of Alberta Health Services.

All South Zone residents are encouraged to ensure that they, and their children, are up-to-date on immunizations.

Important Notice:

Starting August 21, AHS will also be offering booster doses of pertussis immunization to children aged 10, 11 and 12, living in the South Zone of Alberta Health Services. The booster dose clinics are for children in this age range only, and only available for a limited time. Immunization will be offered by appointment, free of charge, regardless of the child’s routine immunization history. Book your child’s appointment today. Visit the online schedule for clinic schedules, or call your local public health office/community health centre.

For more information on these booster dose clinics, please visit our clinic schedule.

Protect yourself & your family: All Albertans

To reduce the risk to South Zone residents, and all Albertans, we need to ensure as many people as possible are up to date with their immunizations.

Please be sure that you and your children are up to date on all recommended immunizations, including those that protect against pertussis.

Find the routine childhood immunization schedule here, and see below for additional routine recommendations for adult protection from pertussis.

Routine Immunization Recommendations*:

  • In Alberta, vaccine that protects against pertussis is offered to children, free of charge, through Alberta’s Routine Childhood Immunization schedule.
  • All adults 18 years of age and older are advised to receive one adult dose of pertussis-containing vaccine.
  • Pregnant women in the third trimester (after 26 weeks), who have not received an adult dose of pertussis containing vaccine, are always offered pertussis-containing vaccine in Alberta.
  • In specific ares of the province where risk of pertussis is increased, all pregnant women in third trimester will be offered pertussis-containing vaccine, regardless of whether they have received an adult dose already, or not.
  • Offering vaccine to women in the third trimester of pregnancy is an important step in protecting both the mother and their infant, as infants are the most vulnerable to developing severe complications from pertussis.

*Children aged 10, 11 and 12 years, living in the South Zone of Alberta Health Services, will be offered a booster dose of pertussis immunization, for a limited period of time only, starting August 21. This is not part of the routine schedule. This is being offered as part of the outbreak control strategy, related to the ongoing South Zone pertussis outbreak. Please visit our Questions & Answers for more information, and see our clinic schedules.

Pertussis Quick Facts:

  • Pertussis (whooping cough) is a bacterial infection of the airways. It is easily spread (by sneezing or coughing) and by direct contact with someone who is infected.
  • The pertussis bacteria can live for two to five days on dry objects like clothes, glass or paper.
  • The infection can cause coughing so severe that children and adults can have difficulty breathing or eating, and the coughing can last for months.
  • Pertussis can lead to pneumonia, convulsions, brain injury and even death. Children with serious complications may require long-term hospitalization, and babies are particularly vulnerable, including to death.
  • Those who are unvaccinated or under-vaccinated are at risk.

What are the symptoms of pertussis?

Pertussis illness starts with a runny nose, sneezing, fever and mild cough.

Typically, over about 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.

Older children and adults may experience milder symptoms, such as a prolonged cough with or without fits or whooping sound; however, in anyone, the cough may last for two months or longer.

What should I do if I think I or a loved one has pertussis?

People who suspect they, or a family member, may be sick with pertussis should stay at home and call a family physician or Health Link at 811 before seeking medical care.

Individuals with a confirmed case of pertussis should stay home from work, school or childcare until five days of antibiotics have been completed.
