Measures introduced to reduce transmission of COVID-19 infections during 2020-2021 suppressed transmission of group A streptococcal (GAS) infections, particularly in children. Following the lifting of public health restrictions in the UK in Feb-2022, Group A Streptococcus presentations – including scarlet fever and invasive Group A Strep – rose significantly in England, although iGAS still remained very rare.
After a period of very high incidence in December 2022, scarlet fever notifications are now in line with what is expected at this time of year.However, iGAS notifications remain slightly higher than normally seen at this point in the season.
New research by UKHSA presented at this year’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID 2023, Copenhagen, 15-18 April) shows that while no new strains emerged in 2022, emm1, which is more likely to cause severe disease, was more common than in previous years.
Analysis of the populations impacted by the increase in infections found that pre-pandemic, iGAS incidence was higher in the most deprived quintiles, but post-pandemic the highest was in the second most affluent quintile. Further research is needed to understand the reasons for this.

During the 2022-2023 winter season Denmark experienced a surge in infections caused by group A streptococci (GAS), including the more dangerous, invasive types of infections (iGAS). Incidence of iGAS is highest among the elderly, but the largest relative increase from previous seasons was seen among children. The study is being presented to the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID 2023, Copenhagen, ...
Strep A infections among children surged in France across 2022, after nearly two-years of COVID-related low case numbers

New research from France shows that infections cause by Group A Streptococcus (GAS) fell by 80% as the first COVID lockdown took effect in March 2020 and stayed at low levels until March 2022, from which point they increased by 18% a month to rise well above pre-COVID levels.

Antibiotics help to fight bacterial infections, but they can also harm the helpful microbes living in the gut, which can have long-lasting health consequences.
Now new research being presented at this year’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) in Copenhagen, Denmark (15-18 April) has identified ...
Disturbed sleep may partially explain post-COVID condition (long COVID) breathlessness
2023-04-16
*Note: this is a joint press release from the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) and The Lancet Respiratory Medicine. Please credit both the congress and the journal in your stories*
A major UK study has discovered that the disturbed sleep patterns in patients hospitalised with COVID-19 was likely to be a driver of breathlessness.
The study of patients in 38 institutions across the UK was led by University of Manchester and Leicester, presented at the European Congress of Clinical Microbiology & Infectious Diseases (Copenhagen, 15-18 April) and published in The Lancet ...
Bacterial consortium therapy for prevention of recurrent c difficile infection
2023-04-15
About The Study: Among adults with laboratory-confirmed Clostridioides difficile infection (CDI) with one or more prior CDI episodes in the last six months and those with primary CDI at high risk for recurrence, high-dose VE303 (a novel oral microbiome-directed therapy composed of nonpathogenic, nontoxigenic, commensal strains of Clostridia) prevented recurrent CDI compared with placebo. A larger, phase 3 study is needed to confirm these findings.
Authors: Jeffrey L. Silber, M.D., of Vedanta Biosciences Inc., in Cambridge, Massachusetts, is the corresponding author.

Filtering pollution: A microfluidic device for collecting microplastics via acoustic focusing
2023-04-15
Plastic debris particles smaller than 5 mm in size, known as microplastics (MPs), are a serious environmental concern. Formed by the breaking down of plastic waste due to wear and tear and sunlight or produced by fiber waste in laundry wastewater and as microbeads in beauty products, they adsorb and introduce harmful chemicals that pollute the environment. By 2050, MPs might outnumber the fish in the oceans. Under these circumstances, the collection and removal of MPs from water are crucial.
Conventionally, MPs are collected by filtering water through meshes. ...
