Without A Vaccine, Researchers Say, Herd Immunity May Never Be Achieved

Mon, 2020-07-27 19:27 — mike kraft

As the coronavirus continues to spread rapidly throughout the U.S. and beyond, many are wondering: How on earth will this end? In an interview televised this week, President Trump reiterated his belief that sooner or later the virus will burn itself out. "I will be right eventually," the president told Fox News host Chris Wallace. "It's going to disappear, and I'll be right."

But scientists are increasingly of the view that this virus will not disappear. In interviews and correspondence with more than a dozen researchers around the world, NPR found that the vast majority believes the virus will persist at some level for a long time in places like the U.S. and Europe.

Multiple vaccine doses could be necessary to protect from coronavirus, Bill Gates says

Thu, 2020-07-23 20:38 — mike kraft

Microsoft co-founder Bill Gates said Wednesday that people could need multiple doses of a potential coronavirus vaccine to immunize themselves from the coronavirus. If necessary, the multiple doses could require more than 7 billion vaccinations to be administered worldwide.

"None of the vaccines at this point appear like they'll work with a single dose," Gates said. "That was the hope at the very beginning."

The billionaire philanthropist, who has donated $300 million towards the global effort to combat COVID-19 through the Bill & Melinda Gates Foundation, told "CBS Evening News" anchor and managing editor Norah O'Donnell that deploying a coronavirus vaccine will require a global effort.

Rigorous wildlife disease surveillence needed

Sat, 2020-07-11 05:25 — mike kraft

Rigorous wildlife disease surveillance Evidence suggests that zoonotic (animal origin) coronaviruses have caused three recent emerging infectious disease (EID) outbreaks: severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and the current coronavirus disease 2019 (COVID-19) pandemic. In the search for an intermediate host for SARS coronavirus 2 (SARS-CoV-2, which causes COVID-19), studies have identified SARS-CoV-2–like strains in bats ([ 1 ][1]) and pangolins ([ 2 ][2]), but these do not contain the same polybasic cleavage site that is present in SARS-CoV-2 ([ 3 ][3]).

The Case for Improved Diagnostic Tools to Control Ebola Virus Disease in West Africa and How to Get There

Sat, 2015-06-13 03:12 — mike kraft

PLOS by Arlene C. Chua,Jane Cunningham,Francis Moussy, Mark D. Perkins,and Pierre Formenty June 11 2015

...Since the identification of Ebola in Guinea in March 2013, rapid deployment of international mobile laboratories through WHO networks—Global Outbreak Alert and Response Network (GOARN) [2] and Emerging and Dangerous Pathogens Laboratory Network (EDPLN) [3]—has been vital to outbreak control operations. Deployable laboratories from multiple international organizations have been established near Ebola treatment centers (ETC) in Guinea, Liberia, and Sierra Leone....

However, several technical and social factors conspire to delay diagnosis, starting with weak surveillance systems and slow patient access to centralized ETCs. While the mean processing time is 5 hours (time difference from when samples are received in the laboratory to when they are tested), there is a marked difference in the time from when the samples are collected from suspected patients to the time they are received by the laboratory
