Following up, Albert Osterhaus and his colleagues at Erasmus University in Rotterdam, the Netherlands, inoculated six ferrets and six domestic cats in their tracheas with a SARS coronavirus strain derived from a deceased Hong Kong patient. Three of the six ferrets got sick, and one died; the cats appeared to remain healthy. But pharynx swabs showed that all of the animals shed the virus 2 days after inoculation, Osterhaus reports in the 30 October issue of Nature. They spread the disease too: When noninoculated cats or ferrets were put together in a cage with infected ones, they, too, became infected. … [Read more...] about Two Species Join Club SARS
So in the end, will COVID-19 be good for the environment or bad? The last US Energy Information Administration’s last Short Term Energy Outlook was released on March 18—so basically a lifetime ago—and is therefore moot. Their next outlook, due out April 7, will contain their first estimate of the pandemic’s impact on emissions and oil prices. But like much else about the virus—the death toll, for instance—we can’t know its ultimate effect on the climate until the pandemic has run its course. And just as with the virus’ effect on human health, its ultimate effect on the climate depends largely on how governments deal with it. … [Read more...] about Will SARS-CoV-2 have a long-term impact on the climate?
To stay safe, we recommend sanitizing your smartphone after every time you use it in public. When you return home, wash your hands properly and sanitize your smartphone at the same time. If you wash your hands without sanitizing your smartphone, you could then touch your smartphone, get the SARS-CoV-2 virus on your fingers, and then spread it to other surfaces—or your face, which could result in infection. … [Read more...] about How Long Can Coronavirus Live on a Smartphone?
Data on whether pregnant women have more severe cases of COVID-19 or less are unclear. Reports from China involving more than a dozen women infected with COVID-19 late in pregnancy suggest their symptoms, if any, are similar to those of other adults. But Denise Jamieson, an expert on emerging infectious diseases and pregnancy at Emory University, says it is too soon to understand the full impact of the disease during pregnancy. “I’ve stopped saying the data we have are reassuring,” she says. “We don’t have nearly enough information to draw conclusions.” … [Read more...] about New coronavirus leaves pregnant women with wrenching choices—but little data to guide them
The very first vaccine was developed by a scientist named Edward Jenner in the late 18th century. In a famous experiment, Jenner scraped pus from a milkmaid with cowpox -- a type of virus that causes disease mostly in cows and is very similar to the smallpox virus -- and introduced the pus into a young boy. The young boy became a little ill and had a mild case of cowpox. Later, Jenner inoculated the boy with smallpox, but he didn't get sick. Jenner's first injection of cowpox pus trained the boy's body to recognize the cowpox virus and, because it's so similar to smallpox, the young man was able to fight it off and not get sick. … [Read more...] about Coronavirus treatments: Chloroquine, vaccines and the drugs fighting COVID-19
