Coronavirus FAQ

What is a coronavirus? Coronaviruses are a group of viruses that cause diseases in mammals, including humans, and birds. Why are they called coronaviruses? The name derives from the fact that the viral capsule has a “halo” or “crown” surrounding it. What do coronaviruses do? In humans, the virus infects the airways giving rise to flu-like symptoms, a runny nose, cough, sore throat and fever, these are usually mild, but in rare cases can be lethal. Is there a vaccine against coronaviruses? No. Are there any drugs to block or treat infection? No. When were coronaviruses first discovered? In the 1960s Any details? The first one discovered was an infectious bronchitis virus in chickens. At about the same time two viruses from the nasal cavities of human patients with the common cold were identified and dubbed human coronavirus 229E and human coronavirus OC43. So coronaviruses cause the common cold? They are usually present when someone has a cold, so yes, pretty much. Why are we so worried about them? Some coronaviruses cause serious respiratory tract infection that is far worse than the usual symptoms of the common cold. In the elderly, infants, people with compromised lung function (such as asthma patients, COPD sufferers, people with lung cancer), an infection can ultimately be fatal, often through the development of pneumonia. Is the Wuhan coronavirus a dangerous form? It has infected several hundred people that we know about so far...

CONCLUSIONS: Despite the significant variability in frequency and duration of prone positioning and respiratory supports applied, prone positioning was associated with improvement in oxygenation variables without any reported serious adverse events. The results are limited by a lack of controls and adjustments for confounders. Whether this improvement in oxygenation results in meaningful patient-centered outcomes such as reduced intubation or mortality rates requires testing in well-designed randomized clinical trials.

OBJECTIVES: To determine if a restrictive visitor policy inadvertently lengthened the decision-making process for dying inpatients without coronavirus disease 2019. DESIGN: Regression discontinuity and time-to-event analysis. SETTING: Two large academic hospitals in a unified health system. PATIENTS OR SUBJECTS: Adult decedents who received greater than or equal to 1 day of ICU care during their terminal admission over a 12-month period. INTERVENTIONS: Implementation of a visit restriction policy. MEASUREMENTS AND MAIN RESULTS: We identified 940 adult decedents without coronavirus dis...

OBJECTIVES: To determine the diagnostic and clinical utility of trio-rapid genome sequencing in critically ill infants. DESIGN: In this prospective study, samples from critically ill infants were analyzed using both proband-only clinical exome sequencing and trio-rapid genome sequencing (proband and biological parents). The study occurred between April 2019 and December 2019. SETTING: Thirteen member hospitals of the China Neonatal Genomes Project spanning 10 provinces were involved. PARTICIPANTS: Critically ill infants (n = 202), from birth up until 13 months of life were enrolled based on eligibi...

CONCLUSIONS: Circulating immune cells profile differs between mild and severe coronavirus disease 2019 patients. Severe coronavirus disease 2019 is associated with a unique immune profile as compared with sepsis. Several immune features are associated with outcome. Thus, immune monitoring of coronavirus disease 2019 might be of help for patient management.

OBJECTIVES: We performed a comprehensive health assessment in mechanically ventilated coronavirus disease 2019 survivors to assess the impact of respiratory and skeletal muscle injury sustained during ICU stay on physical performance at 3 months following hospital discharge. DESIGN: Preregistered prospective observational cohort study. SETTING: University hospital ICU. PATIENTS: All mechanically ventilated coronavirus disease 2019 patients admitted to our ICU during the first European pandemic wave. MEASUREMENTS AND MAIN RESULTS: At 3 months after hospital discharge, 46 survivors underwent a...

In this study, we sought to retrospectively validate this protocol to cohorts of critically ill patients from our hospital. DESIGN: We applied our hospital-adopted guidelines, which defined severe and major chronic conditions as those associated with a greater than 50% likelihood of 1- and 5-year mortality, respectively, to a critically ill patient population. We investigated mortality for the same intervals. SETTING: An urban safety-net hospital ICU. PATIENTS: All adults hospitalized during April of 2015 and April 2019 identified through a clinical database search. INTERVENTIONS: None. MEASU...
