Experts say the recent spike in invasive strep cases in Canada could be due to the removal of COVID-19 pandemic restrictions and a lack of immunity in children. Invasive group A streptococcus (iGAS) is less common but more severe than other types of streptococcus, and it can cause serious conditions, including meningitis and toxic shock syndrome. While Canadians don't need to "lose sleep" over the recent spike, they should stay informed and use common sense, such as practicing good hygiene and staying home if sick. If diagnosed, starting antibiotics early is advised.
Strep infections have remained high in the US this spring, even compared to pre-pandemic years. The CDC reported that emergency department visits for regular strep infections reached a five-year high in February and March. Rates of invasive group A strep infections have also been higher than usual, particularly in children and older adults. Doctors have a few theories as to why strep infections have persisted at high levels, including a decline in cases during the pandemic due to Covid mitigation measures, which then left people more susceptible later. The high rate of strep infections has been extra difficult because of a shortage of the antibiotic amoxicillin.
Strep throat infections remain high even as the winter’s respiratory virus season fades, and in some cases, pediatric formulations of some antibiotics are in short supply. Invasive strep, a more severe form of strep that can infect the bloodstream, has also increased in children and adults. Infectious-disease experts answer common questions about strep, its symptoms, and the antibiotic shortages affecting some parts of the country. Symptoms of strep throat include sore throat, fever, and swollen lymph nodes, and it is typically treated with antibiotics.
Health officials nationwide have been concerned about a rise in strep throat cases, including an unusual nationwide rise in what is called "invasive strep throat." While invasive strep is rare, it can cause problems all over the body if left untreated. Cleveland public health official Dr. Dave Margolius warns not to ignore symptoms and to seek medical attention if you suspect you or your child has strep throat.
