TORONTO \u2014 The number of emergency department visits for pneumonia more than doubled last fall over the previous year, the Canadian Institute for Health Information says.<\/p>\n
The new data released Thursday said young people between five and 19 years old were the hardest hit. <\/p>\n
\u201cThis is actually the largest increase in pneumonia-related emergency department visits that we\u2019ve seen post-COVID,\u201d said Tanya Khan, CIHI\u2019s manager of hospital data advancement and engagement, in an interview. <\/p>\n
Pneumonia didn\u2019t make the top 10 list of reasons for visiting the ER in 2023-24 but shot up to No. 3 \u2014 after abdominal and pelvic pain and throat and chest pain \u2014 in 2024-25, Khan said. <\/p>\n
Dr. Anna Banerji, a pediatric infectious diseases specialist in Toronto, said the CIHI numbers likely reflect an influx of patients with atypical pneumonia \u2014 known as walking pneumonia \u2014 during last year\u2019s respiratory illness season. <\/p>\n
Walking pneumonia usually causes milder symptoms than other types of pneumonia, including cough, fever and fatigue.<\/p>\n
\u201cA lot of people with this kind of pneumonia can get better on their own,\u201d Banerji said. <\/p>\n
But in some cases, walking pneumonia can be severe and lead to neurological symptoms and rashes, she said. <\/p>\n
Parents should seek medical attention for their kids if their cough, fever or fatigue persist. <\/p>\n
Walking pneumonia is usually caused by a bacteria called mycoplasma pneumoniae. If treatment is required, an antibiotic from the macrolides class of medications \u2014 which includes azithromycin, clarithromycin and erythromycin \u2014 is needed instead of the amoxicillin commonly used against pneumonia. <\/p>\n
Mycoplasma bacteria \u201cdoesn\u2019t have the cell wall that antibiotics like amoxicillin attack, so that\u2019s why amoxicillin and the penicillins don\u2019t work for this kind of pneumonia,\u201d Banerji said. <\/p>\n
Banerji said it\u2019s not known if walking pneumonia will make a significant reappearance this fall, but noted various viruses and bacterial infections increased after COVID-19 precautions \u2014 such as masking \u2014 stopped.<\/p>\n
That includes an especially bad season for respiratory syncytial virus that hospitalized many children a couple of years ago, she said. <\/p>\n
Shirley Quach, director of person-centred care and programs for the Lung Health Foundation, said epidemiological data shows walking pneumonia cases follow a cycle where the number of infections peaks every three to seven years. <\/p>\n
\u201cWhile last year could be the apex of the cycle, we should still be watching out for walking pneumonia this fall … irrespective of the cycle,\u201d Quach said in an email. <\/p>\n
Quach said this is the time of year when respiratory illnesses start appearing in greater numbers as people spend more time indoors and children go back to school. <\/p>\n
\u201cThat kind of proximity makes it easier for bacteria and viruses to easily spread through respiratory droplets, such as coughing, and sneezing. People can be infected without symptoms and pass on the infection to people they interact with closely,\u201d she said. <\/p>\n
The CIHI data recorded 7,542 emergency department visits for pneumonia across Canada in September 2023 and 16,489 in September 2024 \u2014 a 119 per cent increase. <\/p>\n
In October 2023 there were 10,432 visits, rising to 24,242 visits in October 2024 \u2014 a 132 per cent increase. <\/p>\n
In November 2023 there were 12,774 pneumonia visits and in November 2024 there were 28,308 \u2014 a 122 per cent rise. <\/p>\n
CIHI estimates it has data from at least 89 per cent of emergency departments in Canada. <\/p>\n
