June 21, 2023 – Severe group A streptococcal infections are increasing in countries world wide. including the United Statesin line with latest data from the CDC.
Group A Streptococci normally cause mild illnesses comparable to strep throat and scarlet fever. But they may also cause more serious illnesses comparable to flesh-eating necrotizing fasciitis and streptococcal toxic shock syndrome, often known as invasive group A streptococcal infections.
These infections fell by 25% throughout the COVID-19 pandemic and were particularly low amongst children. The variety of milder infections also fell. But in 2022, severe infections fell sharply again, especially amongst children.
Infections increased earlier within the winter/spring period – September to November – than in a typical 12 months and reached higher levels than before the pandemic in lots of parts of the country, comparable to Colorado and Minnesota.
Now, in 2023, invasive infections remain high amongst children in some parts of the country, even after respiratory viruses comparable to influenza and respiratory syncytial virus (RSV) have declined in those areas. Some parts of the country have also seen high rates of invasive infections amongst older adults.
Less severe streptococcal A infections in children have returned to levels similar or higher than those in pre-pandemic years.
An identical resurgence of invasive infections after the pandemic has been observed in other countries, including Canada, the United Kingdom, France and Denmark.
While group A strep throat could be very common and causes only mild or no symptoms in most individuals, severe infections are frequently quite rare. They are inclined to affect essentially the most vulnerable people: those that are already infected with one other virus, have multiple chronic illnesses, or have an open wound.
If you will have a strep throat infection, you must look ahead to fever, headache, or confusion, as these may indicate a more serious illness.
