Study highlights a rapidly increasing patient population with long COVID and lack of treatments

A new UK study of more than 2,000 patients after hospitalization with COVID-19 presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID 2022, Lisbon 23-26), and published in The Lancet Respiratory Medicine shows that, one year after having COVID-19, only around one in four patients feel fully well again.

Heterologous booster dose leads to better SARS-CoV-2 vaccine performance, study shows

A new study on Chile's national COVID-19 vaccination program, to be presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID 2022, Lisbon 23-26), and published in The Lancet Global Health, shows that giving a different type of vaccine (heterologous) for the third or 'booster' dose than was received for the first two doses, leads to better vaccine performance than using the same (homologous) inactivated SARS-CoV-2 vaccine for all three doses.

Research identifies inadequate PPE management in COVID-19 testing centers as source of major cross-contamination

Lack of glove changes at COVID-19 testing centers in Belgium led to major cross-contamination of samples and a high rate of false positive results, research being presented at this year's European Congress of Clinical Microbiology & Infectious Diseases in Lisbon, Portugal, (23-26 April) has found.

C. difficile study finds the sharing of multiple antibiotic-resistance genes between pigs and humans

A study investigating samples of the superbug Clostridioides difficile across 14 pig farms in Denmark finds the sharing of multiple antibiotic-resistance genes between pigs and human patients, providing evidence that that animal to human (zoonotic) transmission is possible.

Research identifies the third day of hospitalization as a tipping point in progression of COVID-19 pneumonia

New research being presented at this year's European Congress of Clinical Microbiology & Infectious Diseases in Lisbon, Portugal, (23-26 April), has identified the third day of hospitalization as a tipping point in the progression of disease among symptomatic patients admitted for COVID-19 pneumonia.

Disease-causing amoebas that live on organic leafy vegetables could be a threat to public health

New research to be presented at this year's European Congress of Clinical Microbiology & Infectious Diseases in Lisbon, Portugal (23-26 April), suggests that disease-causing amoebas that live on organic leafy vegetables can shelter human pathogens like Pseudomonas, Salmonella, and Helicobacter and are a potential risk to public health.
