On Monday [26 Jun 2023], Manitoba Health announced that since January
it has received 154 reports of confirmed or probable cases of whooping
cough — 152 of these cases were in the Southern Health region.

These cases include 30 infants aged one or younger; 80 kids aged one
to 9 [years]; 24 kids aged 10 to 19 [years]; and 20 cases in adults.
The province noted that the outbreak includes 78 females and 76 males,
and has resulted in 55 visits to emergency departments, as well as two
admissions to pediatric intensive care. No one has died.

Whooping cough is a contagious illness that can be prevented by a
vaccine. It is caused by a bacterium [Bordetella pertussis] that is
often spread through respiratory droplets in the air from coughing or
sneezing. The illness is most contagious at the beginning stages.
Initially, whooping cough has similar symptoms to the common cold. It
starts with a mild fever, runny nose, and cough, but can end up with
coughing fits that can last for one to 10 weeks. These symptoms
usually appear 7 to 10 days after exposure.

Whooping cough affects people of all ages, but infants and pregnant
people in their 3rd trimester are at highest risk. Some of the most
severe complications include pneumonia, seizures, brain swelling, and

Manitobans are reminded that the vaccine is safe and effective. It’s
also the best way to prevent infection and severe symptoms and limit
the spread. Children should be vaccinated against whooping cough at 2,
4, 6, and 18 months; between the ages of 4 and 6; and in Grades 8 or
9. The vaccine is also recommended for those who are pregnant.

Manitoba Health has sent a follow-up letter to parents and caregivers
with children born in 2019, 2020, and 2021 who may be missing routine

Anyone who has questions or concerns about immunizations is encouraged
to speak to their healthcare provider, public health office or by
calling Health Links at 204-788-8200. Manitobans with whooping cough
symptoms should see their healthcare provider.
