Still, veterinarians want more information. Though human tests might work on animals, they are in short supply—and veterinarians prefer species-specific tests, anyway. Several labs have developed a SARS-CoV-2 test for pets, but none has begun to broadly administer it. The U.S. Department of Agriculture (USDA) has advised against it, and many experts are concerned about spreading unwarranted fear—especially amid reports that some owners have begun to abandon their pets. “Even though we have no evidence that pets can transmit the virus, we desperately need [more] evidence one way or the other,” says Timothy Baszler, executive director of the Washington Animal Disease Diagnostic Laboratory (WADDL), which announced 2 weeks ago that it had developed a COVID-19 test for pets. … [Read more...] about Should pets be tested for coronavirus?

Duggal and other advocates have criticized India’s large-scale closure, saying area-specific lockdowns are more humane and practical in India. But most experts agree a national lockdown was needed. Shahid Jameel, an Indian virologist and head of the Wellcome Trust/DBT India Alliance, notes that measures taken in previous weeks—including halting international arrivals—had not slowed the rate of increase in cases. “The experience from other countries has shown that if you lock down early, if you catch yourself early on the curve, there’s a better chance of limiting the spread,” he says. … [Read more...] about 1.3 billion people.

Micron Technology has opened its expanded chip plant in Singapore that now supports advanced 3D NAND technology and the Singapore government expects to see growth return to the semiconductor sector, as demand for smart devices increases and the deployment of new technologies such as 5G and autonomous vehicles takes shape. … [Read more...] about Fitbit and Singapore to team up on ‘smart nation’ health project
Some companies are working on rapid serological tests that can be delivered at the point of care. SureScreen Diagnostics, for example has developed a testing strip to detect antibodies to the coronavirus in the blood; it works a bit like an at-home pregnancy test, with a paper readout and a colored line to indicate infection. The company touts the test as a way to work around the shortage of the swabs needed for PCR-based tests. But rapid antibody testing likely won't help detect cases early, Pritt said, as it typically takes around 8 days for the body to mount an antibody response to the virus. Serological testing may be useful in some cases where someone has been sick for more than 8 days without access to a test for active infections, she said. … [Read more...] about Coronavirus testing is ramping up. Here are the new tests and how they work.
Myron Levine, a vaccine researcher at the University of Maryland School of Medicine who has conducted challenge experiments for more than 40 years, doubts traditional clinical trials for COVID-19 vaccine candidates will be as slow as some fear. “I think we’re going to move very, very fast,” he says. Because of the high levels of new infections occurring in many places, conventional trials will reveal a vaccine’s worth on the same timeline as a human challenge. “I cannot imagine that it would be ethical and would really speed up what we have to do.” … [Read more...] about Speed coronavirus vaccine testing by deliberately infecting volunteers?
