An outbreak of pertussis in the south zone of Alberta Health Services has continued to grow.
There are now 146 identified cases of pertussis, or whooping cough as it is commonly known, including a small number in central zone.
The majority of cases are among children between one and nine years old, but some adults have also been affected.
Newborns and young children are most vulnerable for severe illness and complications.
Five children have required hospitalization during the course of this outbreak.
The newly-reported cases indicate the outbreak is now present in Medicine Hat and Lethbridge, as well as Coaldale, Taber, Vauxhall, Grassy Lake, Bow Island, County of Forty Mile, Seven Persons, and Fort Macleod.
Many of these communities have significantly low childhood immunization rates and there is evidence of transmission within households, community events and gatherings and at some schools.
Cases have been identified at schools and other community locations such as churches and sites where children gather to take lessons.
AHS is issuing a reminder to all people of the importance of immunization, particularly in small children, to prevent further illness.
Pertussis is a bacterial infection that causes severe and prolonged coughing that lasts for weeks.
It can impact people of all ages but infants one year and younger are at greatest risk of serious complications, including pneumonia, convulsions, brain damage and death.
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.
Immunization is the best method to protect against and limit the spread of pertussis, along with regular hand washing and remembering not to share drinks, food, or cutlery.
If an individual thinks they may be sick with pertussis, they should stay home and call a family physician or Health Link at 811, before seeking medical care.
People with confirmed pertussis should stay home until five days of treatment with appropriate antibiotics have been completed.
