Factors Associated with ARDS in COVID-19 Identified

 Patients with COVID-19 present primarily with fever, myalgia or fatigue, and dry cough. Although most patients are thought to have a favorable prognosis, older patients and those with chronic underlying conditions may have worse outcomes. More...

SARS-Cov-2 Specific Antibody Responses in COVID-19 Patients

 The rapid identification of the etiology and the sharing of the genetic sequence of the virus, followed by international collaborative efforts initiated due to the emergence of SARS-CoV-2 have led to the rapid availability of real-time PCR diagnostic assays that support the case ascertainment and tracking of the outbreak. More...

The COVID-19 Coronavirus Remains Viable for Hours or Days on Solid Surfaces

 A recently published paper sheds light on how coronavirus spreads through the air and how long it remains viable on various solid surfaces. More...

Plasma Virome of Brazilians with Unexplained Symptoms of Infection

 Deep sequencing of nucleic acids in clinical samples now allows the identification of any known infectious agents, resulting in improved diagnostic capabilities. Blood from healthy people with high exposure to viral infections has also been analyzed using metagenomics. More...

SARS-CoV-2 Detected in Multiple Sample Types

 An epidemic of respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began in China and has spread to other countries. Real-time reverse transcriptase–polymerase chain reaction (rRT-PCR) of nasopharyngeal swabs typically has been used to confirm the clinical diagnosis. More...

Featuring a short duration time of only 18 minutes, the Elecsys BRAHMS PCT assay can be easily added to any of the automated cobas immunoanalyzer platforms (Photo courtesy of Roche Diagnostics).

Serial Procalcitonin Measurements Utilized in Hospitalized Community-Acquired Pneumonia

 Community-acquired pneumonia (CAP) refers to pneumonia (any of several lung diseases) contracted by a person with little contact with the healthcare system. CAP, the most common type of pneumonia, is a leading cause of illness and death worldwide. Its causes include bacteria, viruses, fungi and parasites. More...

Microbiome Composition Predicts Outcome Among Stem Cell Transplant Patients

 Allogeneic hematopoietic stem cell transplants are common among patients with blood cancers, and while they may cure the disease, such transplants can also lead to complications such as graft-versus-host disease and infections. More...
