🚨BREAKING: Scientists analyzed genomic data to determine the origin of the deadly new #coronavirus:

“Our analyses clearly show that #SARSCoV2 is NOT a laboratory construct or a purposefully manipulated virus.”

@NatureMedicine @thespybrief #COVID19
nature.com/articles/s4159…
“It is improbable that #SARSCoV2 emerged through laboratory manipulation of a related #coronavirus...the genetic data irrefutably show that #SARSCoV2 is not derived from any previously used virus backbone.”

Instead, here’s how this nasty virus came into being, per this study...
The study provides 2 scenarios that can “plausibly explain” the origin of #SARSCoV2 (new #coronavirus):

1️⃣natural selection in an animal host before zoonotic transfer (transfer from animal to human)
2️⃣natural selection in humans after zoonotic transfer

⚠️In late January, officials in #SouthKorea told experts to quickly develop a test for #COVID19.

“We were very nervous. We believed that it could develop into a #pandemic. We acted like an army."

Just 1 week later, the 1st #coronavirus test was approved.
reuters.com/article/us-hea…
Just 7 weeks after the January meeting, #SouthKorea has tested >290,000 people, identifying >8,000 #COVID19 cases, and new cases are falling off.

The 1st case in the US was detected on the *same day* as South Korea’s, yet only 60,000 #coronavirus tests have been run.🤬
>9,000 U.S. #COVID19 cases have been confirmed, yet experts predict up to *96 million* could be infected in coming months, and 480,000 could die.

“You cannot fight what you cannot see."

Trump's TOTAL failure to quickly deploy #coronavirus testing WILL COST LIVES.🤬

🚨BREAKING: #China says a flu drug approved in #Japan was effective in a study of 340 #coronavirus patients.

Lung X-rays showed improvements in ~91% of patients treated with #favipiravir, compared to 62% of those not treated with drug.

@thespybrief
theguardian.com/world/2020/mar…
Favipiravir inhibits RNA-dependent RNA polymerase, an enzyme that makes copies of the virus’ RNA (not DNA) genome. RNA viruses need this enzyme to make new viral particles, so it’s quite plausible that this drug IS effective against #coronavirus.😃

I worked to develop a similar drug (galidesivir, BCX4430) with the same mechanism of action as #favipiravir, and both drugs show activity against a broad spectrum of different RNA viruses.

Entirely plausible that #favipiravir is active against #COVID19.😃

CORONAVIRUS (COVID-19)
This is a roundup of what I found to be the most interesting & helpful sources on my journey into the void. #Coronavirus #Pandemic #Misinformation #CDC #CPP #WHO
This is for friends & family, but also to raise concern over media censorship & begin a discussion of what are best practices for both traditional & decentralized media outlets. This is a collection of sources to tell a larger story and spark interest.
Very few sources peer reviewed. Some behind paywalls. Some mainstream news. Some International News. Some in other languages (Use chrome). Some Harvard medical Journals. Some unverified. Some factually incorrect. Have some salt with your rice & beans.

New #Coronavirus thread. Tagging someone in this tweet makes me paranoid I ruined it.

The old thread is here though
Here's what the #Coronavirus hospital looks like, 4 days of construction later. They're working as fast as they can but is it too late, regardless?

WHO is working with networks of specialists to analyze 2019-nCoV full genome sequences as they become available.
We have not received evidence that the virus has changed. We await further information from 🇨🇳 officials.

#coronavirus
Current estimates of the new #coronavirus (2019-nCoV) incubation period range from 2-10 days. These estimates will be refined as more data become available.

Understanding the time when infected patients may transmit the new #coronavirus (2019-nCoV) virus to others is critical for control efforts.

[THREAD] China Coronavirus Outbreak
A deadly virus is spreading from Asia, affecting hundreds of people and resulting in dozens of deaths, in what may become a gloabal health epidemic. This thread contains news about the outbreak.
#Coronavirus #WuhanOutbreak #ChinaVirus #WarWatch
On Dec 30, 2019, Chinese authorities confirmed cases of pneumonia of unknown cause in Wuhan, Hubei Province. A team of national experts was sent to carry out detection tests. Patients at a local seafood market were put in quarantine.
#Coronavirus #WuhanOutbreak #ChinaVirus
Liu Youning, a professor of epidemiology and respiratory medicine, told the Global Times that the #coronavirus found in #Wuhan appears to be far less serious than the virus that caused the severe acute respiratory syndrome (#SARS) or the Middle East respiratory syndrome (#MERS).
