Technology Chinese researchers find batch of new coronaviruses in bats
Early Chinese Americans were blamed for diseases and denied health care. So they built their own hospital
Their response is one of countless historical examples of Asian American resistance in the face of anti-Asian racism -- and its legacy lives on today. © Underwood Archives/Getty Images A Chinese apothecary in San Francisco's Chinatown is shown in the mid-1880s. It started with anti-Chinese sentiment in the 1800'sChinese immigrants began making their way to American shores in the mid-1800s, among thousands of people hoping to improve their economic fortunes during the California Gold Rush.
Chinese researchers said Thursday they had found a batch of new coronaviruses in bats including one that may be the second-closest yet, genetically, to thevirus.
According to the researchers, their discoveries in a single, small region of Yunnan province, southwestern China show just how many coronaviruses there are in bats and how many have the potential to spread to people.
Weifeng Shi of the University of Shandong and colleagues collected samples from small, forest-dwelling bats between May, 2019 and November, 2020. They tested urine and feces as well as taking swabs from the bats' mouths.

The only player that provided help over the last week was Mike Zunino (3-for-11 with one home run and four RBI). His profile is well known in the fantasy market (high-strikeout power hitter with plenty of batting average risk).
"In total, we assembled 24 novel coronavirus genomes from different bat species, including four SARS-CoV-2 like coronaviruses," the researchers wrote in a
One was very similar, genetically to the SARS-CoV-2 virus that's causing the current pandemic, they said -- a viral sample called RpYN06 taken from a horseshoe bat species called Rhinolophus pusillus.
It would be the closest strain to SARS-CoV-2 except for genetic differences on the spike protein, the knob-like structure that the virus uses when attaching to cells, they said.
"Together with the SARS-CoV-2 related virus collected from Thailand in June 2020, these results clearly demonstrate that viruses closely related to SARS-CoV-2 continue to circulate in bat populations, and in some regions might occur at a relatively high frequency," they wrote.
Cardinals place Adam Wainwright on COVID-19 injured list
The Cardinals are placing right-hander Adam Wainwright on the COVID-19 injured list, a precautionary move after one of his family members tested positive for the virus, per Woo. In other moves, the Cardinals have activated outfielder Harrison Bader, placed left-hander Andrew Miller on the 10-day IL with a right foot blister, and recalled righty Kodi Whitley, according to Jeff Jones of the Belleville News-Democrat. © Jeff Curry-USA TODAY Sports Wainwright will miss his scheduled start Sunday in Pittsburgh as a result of this IL placement.
Researchers are trying to find where SARS-CoV-2 came from. Although a bat is a likely source, it's possible the virus infected an intermediary animal. The SARS virus that caused an outbreak in 2002-2004 was tracked to an animal called a civet cat.
"Bats are well known reservoirthat cause severe diseases in humans and have been associated with the spillovers of Hendra virus, Marburg virus, Ebola virus and, most notably, coronaviruses. Aside from bats and humans, coronaviruses can infect a wide range of domestic and wild animals, including pigs, cattle, mice, cats, dogs, chickens, deer and hedgehogs," they wrote.
Most of the samples came from species of horseshoe bats. In 2017, researchers sampling a cave in Yunnan found viruses very close genetically to the SARS virus in horseshoe bats.
Three of the samples described in Thursday's report were also close to SARS genetically.
"Our study highlights the remarkable diversity of bat coronaviruses at the local scale, including close relatives of both SARS-CoV-2 and SARS-CoV," they wrote. The bat species they sampled are common across Southeast Asia, including southwest China, Vietnam, Laos and elsewhere.
Although there's some controversy about the origin of the coronavirus pandemic, a World Health Organization report said the most likely source is an animal -- probably a bat.
People hunt and eat bats, and bats can infect other animals that are also hunted and eaten by people. Viruses can infect people when they handle or slaughter the animals.
