Streptococcus pyogenes (group A strep) and surge of infections

AI Thread Summary
Infection with Streptococcus pyogenes, commonly known as group A strep, has recently surged, presenting with atypical symptoms like skin rashes and unexplained swelling, alongside traditional signs like fever and sore throat. This rise has led to tragic pediatric fatalities, with confirmed deaths in the U.S. and Europe, raising concerns about the potential lethality of a new variant or diminished immunity due to pandemic-related social distancing. Health officials in Minnesota and Colorado report significant increases in invasive strep A cases, with Texas Children's Hospital noting a fourfold rise compared to the previous year. The discussion centers on whether this epidemic is due to a lack of exposure during the pandemic or the emergence of a more dangerous variant. The situation highlights the complex interactions of pathogens as society transitions from pandemic restrictions.

Infection with Streptococcus pyogenes - or group A strep, for short - typically produces mild symptoms, such as rash, fever or swollen tonsils leading to the eponymous strep throat. But in recent months, cases related to a rare invasive form of the common bacteria have been popping up across the United States, as well as Europe, often in connection with sometimes confusing symptoms, including skin rashes, fever, a racing heart and unexplained swelling.

The first confirmed pediatric deaths in this country, in two young children in the Denver area, were reported last week. At least 16 children have died of it in the United Kingdom, seven in the Netherlands and two in France.

The rise of invasive strep A is one of a number of unusual ways pathogens have been interacting with us - and each other - amid the end of coronavirus-era social distancing and masking this year.

Is the current surge (epidemic?) of infections a result of lack of exposure during the pandemic, and hence a lessening of folks' immune responses, or is this variant more lethal, or perhaps a combination?

Minnesota health officials said they had seen 46 cases of invasive strep A in all ages in November, more than double the average 20 cases in previous months. Colorado reported that it was investigating not only a rise in invasive strep A cases, but also a possible increase in other severe or invasive bacterial infections in children.

Texas Children's Hospital said it has seen more than 60 patients with invasive strep A in October and November - a fourfold increase from the same period the previous year. . . .

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
