Coronavirus updates: Fauci says temperature checks not reliable – ABC News

Over 20.7 million people across the globe have been diagnosed with COVID-19, the disease caused by the new respiratory virus, according to data compiled by the Center for Systems Science and Engineering at Johns Hopkins University. The actual numbers are believed to be much higher due to testing shortages, many unreported cases and suspicions that some national governments are hiding or downplaying the scope of their outbreaks.

WHO’s Next — The United States and the World Health Organization – NEJM

What’s the proper response to such a disaster? If you were the current U.S. government, you would shut down the Forest Service in the midst of the fire. At least that’s what’s happening now with the World Health Organization (WHO). On July 7, 2020, the President notified the United Nations that the United States plans to withdraw from the WHO (www.nytimes.com/2020/07/07/us/politics/coronavirus-trump-who.html. opens in new tab). The full implications of this decision are not yet clear. The United States is responsible for the largest amount of funding for the WHO, 22% of assessed dues, and provides the largest voluntary contributions — to polio eradication, nutrition, and vaccine programs, for example. Because of the Covid-19 pandemic, measles and polio campaigns have already been suspended in dozens of countries (www.sciencemag.org/news/2020/04/polio-measles-other-diseases-set-surge-covid-19-forces-suspension-vaccination-campaigns. opens in new tab), and these delays will be exacerbated by the withdrawal of U.S. financial support.

Mild COVID, Lingering Heart Effects for ICU Doc – MedPageToday

Despite a mild case, it took months for Janet Shapiro, MD, to fully recover heart function. Janet Shapiro, MD, an ICU physician at Mount Sinai Morningside Hospital in New York City, had just come back to work after a relatively mild course of COVID-19. She had lost her sense of smell and taste, and for a few days had a low-grade temperature and cough.

COVID-19 Tied to Large Vessel Strokes – MedPageToday

Adjusted LVO risk was more than twice that of patients who tested negative for SARS-CoV-2. As many as 36% of patients admitted to hospital with COVID-19 may exhibit neurologic symptoms, according to a study from China. Altered mental status, dysarthria, aphasia, and diffuse corticospinal tract signs are among some of the common manifestations of COVID-19, and can also be seen in patients with acute ischemic infarction.

Doctors Seeing Heart Inflammation In Young People With Coronavirus: ‘Are These People At Risk?’ – CBS News

Several otherwise healthy college athletes with COVID-19 have myocarditis – inflammation of the heart. “You don’t really see the virus molecule in the heart, you see the body’s response to the virus,” says Dr. Raghu Tadikamalla, a cardiologist at the Allegheny Health Network.

SARS-CoV-2 causes immune paralysis in severe cases of COVID-19 – Science Advisory Board

The SARS-CoV-2 virus can cause the paralysis of key immune cells as the COVID-19 disease progresses, and this immune paralysis can be the difference between severe and mild cases of COVID-19, according to a study published in Science on August 11.

Science and Tech

The recent emergence of SARS coronavirus 2 (SARS-CoV-2) has resulted in the alarming spread of the highly infectious and contagious COVID-19 pandemic that is causing catastrophic damage and affecting health, life and death around the world [1,2]. SARS-CoV-2 has also created a COVID-19 ‘infodemic’ crisis with an overabundance of information and misinformation about the origin of the virus, potential therapies, and whether it was engineered in the laboratory. However, the global pace of SARS-CoV-2 and COVID-19 research is providing rapid and critical advances in comparison to that of the previous SARS-CoV, Middle East respiratory syndrome (MERS) and HIV [1,3,4]. COVID-19 has a protean manifestation, and the cryptic transmission of SARS-CoV-2 is characterized by multiple chains of transmission, unlike the SARS-CoV and MERS-CoV viruses that have been reported to occur mainly through nosocomial transmission [3,4]. There are still many unknowns regarding COVID-19, but there are also important lessons to be gleaned from AIDS that are applicable to the COVID-19 pandemic.
Aerosol experts, from engineers to doctors, weigh in on the ability of tiny droplets to transmit the virus that causes COVID-19. Over the past few months, an increasing number of scientists, clinicians, and engineers have called for greater recognition that aerosols, in addition to larger droplets can transmit the novel coronavirus that causes COVID-19. While the difference is literally miniscule, acknowledging this route of transmission would result in significant changes in how the public can bring an end to the global pandemic. In the near term, it would inform social distancing and mask wearing recommendations from local governments, and in the long term, engineers and architects will need to rethink ventilation and air filtration in the design of everything from schools to cruise ships.


Gilead Plans to Make 2 Million Remdesivir Doses This Year – Bloomberg

In May, the antiviral therapy received an emergency-use authorization to treat Covid-19, the disease caused by the novel coronavirus, after a major trial found it sped recovery by about four days in hospitalized patients. It is already being used in clinical practice.


HHS Invests in Diagnostic Labs to Expand COVID-19 Testing Capacity in the United States – HHS

Today, the U.S. Department of Health and Human Services announced combined investments of $6.5 million in two commercial diagnostic laboratories to expand capacity to conduct up to 4 million additional SARS-CoV-2 per month. SARS-CoV-2 is the virus that causes COVID-19. The investments in Aegis Sciences Corporation and in Sonic Healthcare USA will provide critical laboratory equipment supplied by Beckman Coulter Life Sciences and Thermo Fisher Scientific and increase staffing and infrastructure to allow the U.S. to perform an additional 1 million tests each week by early October.


DNA vaccine protection against SARS-CoV-2 in rhesus macaques – Science Magazine

The development of a vaccine to protect against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an urgent biomedical need. Yu et al. designed a series of prototype DNA vaccines against the SARS-CoV-2 spike protein, which is used by the virus to bind and invade human cells. Analysis of the vaccine candidates in rhesus macaques showed that animals developed protective humoral and cellular immune responses when challenged with the virus. Neutralizing antibody titers were also observed at levels similar to those seen in humans who have recovered from SARS-CoV-2 infection.

These are the top coronavirus vaccines to watch – Washington Post

The worldwide effort to create a vaccine for the novel coronavirus kicked off in January, soon after scientists in China posted online the genome of a virus causing a mysterious pneumonia. Vaccine development usually takes years and unfolds step by step. Experimental vaccine candidates are created in the laboratory and tested in animals before moving into progressively larger human clinical trials.

Every country wants a covid-19 vaccine. Who will get it first? – MIT Technology Review

The Chinese company Sinovac Biotech developed an experimental vaccine for SARS back in 2004. That disease went away after killing just 800 people, and the project was shelved. But it meant that when the new coronavirus, SARS-CoV-2, exploded in China last January, the company had a road map for what to do next. Four months later, it published evidence that it could protect monkeys against the disease using a simple vaccine made from killed virus.

Experimental COVID-19 Vaccine – Made From a Genetically Modified Virus – Prevents Severe Disease – Science Daily

An experimental vaccine is effective at preventing pneumonia in mice infected with the COVID-19 virus, according to a study from Washington University School of Medicine in St. Louis. The vaccine, which is made from a mild virus genetically modified to carry a key gene from the COVID-19 virus. [Related study in Cell Host & Microbe)

Who Will Benefit from a Successful Chinese COVID-19 Vaccine? – Rand Corporation

The COVID-19 pandemic has impacted the lives of millions of people and brought the global economy to the brink of a deep depression in merely a few months. This crisis has also spurred an unprecedented race to develop a vaccine. Currently, 30 vaccines are already in human clinical trials, eight of which were sponsored by Chinese labs. Multiple countries have also agreed to partner with Chinese labs for the last stage of human trials given that China doesn’t have large scale COVID-19 infections. There seems to be little doubt, then, that China could be among the countries that first produces a successful vaccine for COVID-19. There are several issues before large-scale benefits will accrue globally. Can China produce sufficient doses for its domestic use and for other countries? Which countries are likely to benefit?

The Science of Sourdough: How Microbes Enabled a Pandemic Pastime – Scientific American

The Covid-19 pandemic has tightened our social circles and narrowed the scope of our lives in ways no one imagined just a year ago. But the lockdown also brought an unexpected solace: Everyone, it seems, turned to baking sourdough bread. Social media has been overflowing with photos of frothy sourdough starters — many of them named, like a family pet — and the fresh-baked loaves that result. And though peak sourdough may have passed, many a fridge still contains that jar of starter.
