Across the United States this summer, restaurants and bars, reeling from mandatory lockdowns and steep financial declines, opened their doors to customers — but the short-term gains have led to broader losses.
As stressful as it always is for students applying to college, this year it’s all that — and then some — for the admissions officials trying to decide whether to admit them. Because of the pandemic, many students will be applying without standardized test scores and several other metrics admissions officers at selective schools have long relied on, leaving colleges scrambling to figure out what else they might consider instead.
President Vladimir Putin said Russia cleared the world’s first Covid-19 vaccine for use and hopes to begin mass inoculation soon, even before clinical testing has finished.
A recent modeling effort may help provide some clues. Led by Jose-Luis Jimenez at the University of Colorado Boulder, the charts below estimate the riskiness of different activities based on one potential route of coronavirus spread: itty-bitty particles known as aerosols.
Despite the continued spread of the coronavirus, many colleges around the country plan to welcome students back to campus over the coming weeks. Colleges want to reopen for good, nontrivial reasons. Administrators believe that most students learn better when they are physically assembled in the same place. And they know that the American college experience, at any rate, has long been about more than the classroom. It allows students to cut the umbilical cord, make friends with like-minded people, and pursue extracurricular activities—all of which are much harder to do if your freshman year consists of joining Zoom sessions from your parents’ basement. Many universities also face serious financial problems. If they are unable to reopen this fall, some may collapse.
For critics of aggressive stay-at-home orders, the solution seems clear: Reopen the economy and enough people will eventually become infected by the novel coronavirus to achieve “herd immunity” even before a vaccine is available. The idea is that eventually, a sufficient percentage of the population will have survived COVID-19 and become immune, which in turn protects the rest of the uninfected population by interrupting the spread of the virus.
Since December 2019, the novel COVID-19 outbreak has spread rapidly around the globe and infected millions of people. Although the major transmission route of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is considered to be airborne droplets and close contact, the ocular transmission route has been reported with great concern. The current work summarises the characteristics of SARS-CoV-2, the ocular distribution of the major SARS-CoV-2 binding protein, and the experimental and clinical evidence of the ocular transmission route. Although it seems that the likelihood of the ocular surface being an infection gateway is low, SARS-CoV-2 infection or transmission via the ocular surface may cause conjunctivitis and other ocular discomfort. Therefore, good eye protection is an essential safeguard procedure, especially for medical staff.
Cats can contract an almost always fatal disease that’s caused by a coronavirus that infects only felines. Now preliminary research suggests that two experimental drugs that can cure that disease in cats, called feline infectious peritonitis, might help treat people infected with SARS-CoV-2, the coronavirus behind the pandemic.
A Stanford study shows that in severely ill COVID-19 patients, “first-responder” immune cells, which should react immediately to signs of viruses or bacteria in the body, instead respond sluggishly.
Imagine being young and healthy, a nonsmoker with no preexisting health conditions, and then waking up one morning feeling like you were being suffocated by an unseen force. Back in March, this was my reality. I had just returned from Europe, and roughly 10 days later started having flu-like symptoms. I became weak overnight and had trouble breathing. It felt like jogging in the Rocky Mountains without being in condition, only I wasn’t moving. I went to the hospital, where I was tested for COVID-19. I was one of the first people in Texas given a non-FDA-approved test. My results came back negative. As a social epidemiologist who deals with big data, I was certain it was a false negative.
Eight months into the global pandemic, we’re still measuring its effects only in deaths. Non-hospitalized cases are loosely termed ‘mild’ and are not followed up. Recovery is implied by discharge from hospital or testing negative for the virus. Ill health in those classed as ‘recovered’ is going largely unmeasured. And, worldwide, millions of those still alive who got ill without being tested or hospitalized are simply not being counted.
