A three-year study has found robust evidence that one vaccine for respiratory syncytial virus offers older adults long-term protection, even if efficacy wanes. Despite this, just one dose cut serious illness by nearly two thirds across three seasons.

A decade-long study of 35 million Americans in 10 states has found that group A streptococcus infections have more than doubled. What's more, "strep" – which can cause a bizarre flesh-eating disease – has become increasingly resistant to antibiotics.

The US has recorded its first death due to avian influenza. The man had been infected by a H5N1 variant with a genetic mutation, helping it target upper respiratory tract receptors – one also seen in the Canadian teen who fell critically ill last year.

In a much-needed update to 2003 data on attention-deficit/hyperactivity disorder in the US, a new report has found that 15.5 million American adults have been diagnosed with the condition – and many have been let down by poor access to treatment.

A striking new case study illustrates just how pervasive SARS-CoV-2 aerosol transmission can be, describing a trio of infections in a Taiwan quarantine hotel with the virus likely traveling through walls and floors in a poorly ventilated building.

New modeling from the CDC estimates Omicron subvariants BQ.1 and BQ.1.1 now account for over 10% of all infections in the US. Scientists predict these rapidly spreading variants will drive a new wave of infections in the country over the coming months.

Estimates from the CDC indicate a new Omicron subvariant is becoming prevalent in the US. Dubbed BA.2.12.1, it is likely to be the most infectious version of SARS-CoV-2 to date and experts warn it could be triggering a new wave of cases in the country.

A report from the CDC has found COVID-19 was the third leading cause of death in the US in 2021, after heart disease and cancer. Another new CDC report estimates nearly 60 percent of the US population had been infected with SARS-CoV-2 by February 2022.

New CDC modeling estimates the BA.2 Omicron variant is now dominant in the United States. In related news the FDA has withdrawn its emergency authorization for the COVID-19 antibody treatment sotrovimab as research has found it ineffective against BA.2.

Delta-8 THC is similar to its commonly known psychoactive cousin, delta-9 THC, and new studies are offering the first large-scale insights into what kinds of effects people are experiencing with this unique and under-researched drug.

A report from the CDC has found children who have recovered from COVID-19 infection are more likely to develop diabetes than those with no history of infection. The researchers call for more study into the association between COVID-19 and diabetes.

New data from the Centers for Disease Control and Prevention (CDC) indicate the Omicron variant is rapidly increasing in prevalence in the United States, accounting for nearly three percent of all cases sequenced in the country over the past week.
