The infectious period for a COVID patient is thought to be 10-20 days, based on the severity of the disease. One patient, however, was shedding virus for 105 days and was infectious for 70 of them.
Pfizer and Moderna are producing fewer but more effective (and pricier) vaccines, while AstraZeneca is making a greater number of less effective (and cheaper) vaccines.
From greasy menus to double-dipping, the COVID pandemic will help us say goodbye to some nasty cultural practices.
A new paper attempts to create the best estimate for the COVID infection-fatality rate (IFR), which answers the question, "If I get sick, what is the chance that I will die?" Beware: The virus discriminates.
Opposition to the use of biotechnology to enhance agriculture was always based on junk science. But now these anti-GMO activists look downright silly as cutting-edge biomedical science rescues us from COVID.
Washington State Governor Jay Inslee has canceled Thanksgiving as part of a new COVID lockdown. The Grinch of Whoville couldn't have created a better policy.
New York Governor Andrew Cuomo would rather allow more Americans to become infected with and die from coronavirus than to allow an imperfect vaccine distribution plan to proceed.
Pfizer's vaccine is based on RNA, which is a very unstable molecule that is prone to breaking down. Storing it at -94° F prevents this, but it creates the logistical difficulty of transporting the vaccine.
The value of hydroxychloroquine in treating COVID-19 patients continues to rise from the ashes of refutation in the medical literature. The latest iteration is a meta-analysis of utilizing the drug early in ambulatory patients' care to lessen the undesirable outcomes of infection, hospitalization, and death. Several of our readers and members of our Board of Scientific Advisors believe that this study is important and that we disregard it at our risk. We are letting a proponent of each side make their case. 
People with Type A blood are more susceptible to a particular kind of lung disease, which happens to be triggered by the novel coronavirus that causes COVID-19.
The American media focuses on the failures to control the coronavirus in this country, but a larger perspective shows that the virus is out of control in much of the world, especially in Europe. Some other countries are doing worse than the U.S., at least for the time being.
We don't have an unlimited supply of diagnostic tests for COVID. So, researchers have developed nine simple questions that can predict whether someone is likely to have the disease.
