Dexamethasone, an inexpensive steroid, reduced death by one-third in ventilated COVID-19 patients, and by one fifth in patients receiving oxygen for severe coronavirus symptoms. Preliminary findings suggest one death per eight patients ventilated could be prevented by administering dexamethasone.
Study reveals up to 45% of people infected with COVID-19 were asymptomatic. The findings suggest asymptomatic infections likely played a significant role in the early and ongoing spread of coronavirus.
Roughly 50% of patients hospitalized for COVID-19 experience neurological symptoms including headaches, dizziness, smell and taste disorders, and stroke, a new study reports. Coronavirus may affect the entire nervous system, including the brain, spinal cord, and muscles. Neurological symptoms of COVID-19 may appear before the fever and cough commonly associated with infection.
New coronavirus model finds case spread is concave, meaning the impact of one more infected person diminishes as more people become infected.
New evidence confirms COVID-19 infection is the cause of the Kawasaki-like syndrome affecting children.
Famotidine (Pepcid AC), an over-the-counter medication used to treat indigestion, shows promise as a potential treatment for COVID-19.
Researchers have identified 27 protein biomarkers that can predict whether a patient with COVID-19 is likely to develop severe coronavirus symptoms.
A new study reveals COVID-19 infection rates may correlate with seasonality. Lower humidity is associated with an increase in locally acquired positive cases of coronavirus. The study reports a 1% decrease in humidity could increase the number of coronavirus cases by 6%.
Study reports SARS-CoV-2, the virus that causes COVID-19, was well suited to making the jump from animals to humans by shapeshifting as it gained the ability to infect human cells. The virus's ability to infect humans occurred via exchanging gene fragments from a coronavirus that infected pangolins. The species-to-species transmission was a result of the ability of SARS-CoV-2 to bind to host cells through alterations to its genetic material.
Researchers used data of active COVID-19 case rates from China to set the parameters for the model. Applying the formula to other counties, including the UK, France, and Brazil, they found a match in the evolution of active cases and fatality rates over time.
While the amount of antibodies generated varies widely in patients who have recovered from coronavirus, most people generate at least some antibodies which are intrinsically capable of neutralizing the SARS-CoV-2 virus.
