Old Vaccines May Stop the Coronavirus, Study Hints. Scientists Are Skeptical.

Thu, 2020-07-30 13:16 — mike kraft

Billions of dollars are being invested in the development of vaccines against the coronavirus. Until one arrives, many scientists have turned to tried-and-true vaccines to see whether they may confer broad protection, and may reduce the risk of coronavirus infection, as well.

Old standbys like the Bacille Calmette-Guerin tuberculosis vaccine and the polio vaccine appear to help train the immune system to respond to a broad variety of infections, including from bacteria, viruses and parasites, experts say.

The Devastating Impact of Infectious Disease Outbreaks - ISSA The impact of having a simple conversation with another person is enough to spread diseases. Eleni Sakas ISSA

By Dr. Gavin Macgregor-Skinner | July 29, 2020

As an epidemiologist or “disease detective,” a question I am frequently asked regarding SARS-CoV-2 (the virus that causes COVID-19 disease) is: “How does someone become infected?”

U.S. researchers identify evolutioary orgins of SARS-CoV-2

Tue, 2020-07-28 21:28 — mike kraft

Researchers identify evolutionary origins of SARS-CoV-2 | Penn State University By reconstructing the evolutionary history of SARS-CoV-2, the virus that is responsible for the COVID-19 pandemic, an international research team of Chinese, European and U.S. scientists has discovered that the lineage that gave rise to the virus has been circulating in bats for decades and likely includes other viruses with the ability to infect humans. The findings have implications for the prevention of future pandemics stemming from this lineage.

Hoping to Understand the Virus, Everyone Is Parsing a Mountain of Data

Tue, 2020-07-28 09:25 — mike kraft

CHICAGO — The latest count of new coronavirus cases was jarring: Some 1,500 virus cases were identified three consecutive days last week in Illinois, and fears of a resurgence in the state even led the mayor of Chicago to shut down bars all over town on Friday.

But at the same moment, there were other, hopeful data points that seemed to tell a different story entirely. Deaths from the virus statewide are one-tenth what they were at their peak in May. And the positivity rate of new coronavirus tests in Illinois is about half that of neighboring states.

“There are so many numbers flying around,” said Dr. Allison Arwady, the commissioner of the Chicago health department. “It’s hard for people to know what’s the most important thing to follow.”...
