(2/22). ¿Qué es la Luz Ultravioleta?

Dentro del espectro electromagnético, en la
zona no visible, encontramos las longitudes de onda
comprendidas entre los 10 y los 400 nanómetros, donde encontramos la luz #UVA,
#UVB y la #UVC Image
(3/22) ¿Por qué la UVC es tan especial?

La #UVC se sitúa en el rango de longitudes de onda entre 100 nm y 280 nm. Dentro de este rango UVC, la región situada 220 nm–280 nm se considera #germicida o #GUV por sus siglas en inglés (Germicidal UV) Image

I fully agree with Dr. Krammer here. There are a few problems with human challenge trials for #SARSCoV2 #COVID19 #coronavirus vaccines that have not been adequately addressed.
1. SARS-CoV-2 is a deadly virus, and even though younger people are at a lower risk for severe disease, the risk is not zero. Young people can and do die from COVID-19.

2. We have very little information about the long-term impacts of COVID-19 or "long COVID," but it's clear that recovering from infection does not mean recovery. Dr. @Craig_A_Spencer and I discussed this with @ASlavitt earlier this month

1) Despite the fact that Quebec and Montreal have entered the second wave in the #pandemic, Premier François Legault has maintained that hospitalizations are tracking with optimistic projections made in June. In this thread, I will fact-check this.
2) Since Sept. 1, the province has witnessed a net increase of 69 #COVID hospitalizations, averaging three a day. Compared with scores of hospitalizations reported during the first wave, that number is relatively low. But how does it compare with the projections?
3) In the chart below, the optimistic scenario projected a median of just under 2.5 hospitalizations a day in September. Thus, the current average is at least 20% higher than the government's projections. There’s been a net increase of 40 hospitalizations in the past three days. Image

#coronavirus ES LA ESTRATEGIA

Para estas alturas ya hemos visto a docenas de países de todos los tamaños, colores y sabores, manejar la pandemia de forma buena, regular, mala, y pésima. También hemos visto que lo determinante es sus resultados no es el signo político...
de sus gobiernos, sino la reacción temprana y la aplicación de estrategias adecuadas. Las recomendaciones que han emitido la OMS y docenas de think tanks, centros de investigación y expertos individuales no hacen énfasis sino en las estrategias generales,
que se pueden aplicar en cualquier país. Pero además de las medidas higiénicas/médicas, todas mencionan la comunicación clara. Desafortunadamente ésta no se ha dado de manera uniforme, o bien se ha relajado después de un primer control.

🚨BREAKING: Massive study of more than 5,000 genetic sequences of the #coronavirus reveals continual viral mutations—one mutation in the gene encoding its spike protein may have made the virus MORE CONTAGIOUS.🧬

#COVID19 #SARSCoV2
washingtonpost.com/health/2020/09…
This mutation affects the #coronavirus spike protein—changes amino acid 614 from “D” (aspartic acid) to “G” (glycine)—and is associated with a higher viral load in #COVID19 patients on initial diagnosis.

A larger study in the UK had similar findings.

medrxiv.org/content/10.110…
All viruses accumulate genetic mutations, and most are insignificant. #SARSCoV2 is relatively stable as viruses go.
But every mutation is a roll of the dice, and with widespread transmission in the US, the virus has had abundant opportunities to change.🤬

Une centaine de #migrants dont des enfants sont réunis à #Paris19 ce soir. Sans rien pour dormir, ils comptent sur @Utopia_56 pour avoir des tentes. Hier ils ont été expulsés vers le 93 : actu.fr/?p=36296221

"Ce soir, l'inconnue est totale." À suivre ici pour @actufrparis ⤵️
Problème en plus, la pluie et les rafales de vent qui s'abattent sur le groupe. Il y a au moins 33 familles avec enfants. Les bénévoles d'@Utopia_56 savent que la police les attend sur un des lieux où ils voulaient les installer. "Sans lieu de repli, on ne sait pas quoi faire."
Trois familles dormiront chez des "hébergeurs solidaires", volontaires auprès d'@Utopia_56, ce soir : "Les familles sont prioritaires." Depuis le #coronavirus et le confinement, les hébergeurs se font rares. #Paris19 Image

‼️“It’s wild here.” Cases of #coronavirus explode at #Florida universities.

Some students say @GovRonDeSantis' message that 18–22 year olds have “an extremely low risk of getting sick or being hospitalized" prompted them not to heed #COVID19 guidelines.🤬
miamiherald.com/news/local/edu…
“No one seems to be taking it seriously.”

Although young people have lower risk, they still can get sick & die from #COVID19. And the surge in #coronavirus cases in college towns is a looming threat for older people living in the surrounding communities.
miamiherald.com/news/local/edu…
#Florida was a #coronavirus hot zone BEFORE DeSantis forced schools to reopen for in-person classes. Numerous high schools have already closed, due to #coronavirus outbreaks.

Within weeks, hospitalizations will surge, and the death toll will rise.🤬

1) Health Minister Christian Dubé admitted Tuesday Quebec is having a hard time retracing #COVID19 contacts as the province enters a second wave in the #pandemic. In this thread, I will appeal to the government to authorize the use of Health Canada's COVID Alert notification app.
2) An online consultation commissioned by the government found that 77% of Quebecers believed such an app would be useful, and 75% said they would install it on their smart phones. Yet despite the overwhelming public approval, the government won’t use it.
3) Ontario Health Minister Doug Ford has urged neighboring Quebec to authorize the app. Federal health minister Patty Hajdu has asked Quebec to use it. Quebecers want the app. Yet on Tuesday, even as Dubé declared Laval and the Outaouais to be orange zones, he ruled out using it.

Harvard Global Health Institute say “how could the CDC make this mistake? This is a mess."

‼️A case of #coronavirus reinfection reported in a healthy young US military healthcare provider, who was first infected in March and fully recovered within 10 days. 51 days later, he was reinfected with a DIFFERENT strain by a household member.

#COVID19
reuters.com/article/us-hea…
The man was SICKER the 2nd time, perhaps because the 2nd strain was more potent, or the household contact infected him with a higher load of virus, or antibodies from the 1st infection may have triggered his immune system to respond more strongly to the virus the 2nd time.🧐
Only a very small number of #coronavirus reinfection cases have been documented. The vast majority of suspected reinfection cases were deemed due to reactivation of the virus, rather than true reinfection.

Abbiamo ormai imparato in molti che il #coronavirus si lega a un particolare recettore chiamato #ACE2. Lo fa con una proteina detta #spike. Una interessante novità è che c’è un altro recettore che gioca un ruolo importante e che è diffuso sulle cellule anche più di ACE2 Image
È una proteina chiamata Neuropilina-1. (NRP1) Nelle cellule delle vie respiratorie sono presenti entrambi i recettori e per questo il virus di lega molto bene.
Attraverso le cellule progenitrici dei neuroni dell’olfatto, che hanno molta neuropilina -1, il virus riuscirebbe poi ad arrivare al cervello coi danni neurologici che sempre più si stanno documentando.

1/ Those who follow me know that I think too much and ask too many questions. In my curiosity, I recently stumbled upon a story of a bat cave of coronaviruses, sudden unexplained death, and mysterious poison mushrooms🍄 Buckle up it’s a weird one #medhistory #SARS #Covid_19 🧵👇
2/ It all started with that foolish preprint that was again claiming that SARS-CoV-2 was made in a lab. A claim that no respected scientist or clinician supports, given the lack of evidence, including: @K_G_Andersen @angierasmussen @CT_Bergstrom #COVID19

3/ So, I go back to what evidence we actually have. Because #science is awesome, we have a ridiculous amount of viral genomes that have continued to be tracked from early on in the pandemic:
- 4,678 @nextstrain @trevorbedford
- 84,932 @CovidGenomicsUK

EL PELIGRO DEL LÍDER CARISMÁTICO

Hemos visto el ascenso de líderes carismáticos en el mundo y no, no es bueno en absoluto. Este tipo de persona crea en sus seguidores una fe ciega y aberrante que una vez instaurada es prácticamente imposible de vencer.
Con un conteo de 200 mil muertes, el presidente de EEUU dice que el coronavirus “casi no le afecta a los menores de 18” y que de hecho “no le afecta a casi nadie” (virtually nobody):
Para ponerlo en perspectiva, 200 mil muertes es 30 VECES PEOR que el conteo de la Guerra de Vietnam (60 mil en 10 años), pero sus seguidores le aplauden mientras le escuchan decir que “abran sus escuelas” en medio de un descontrol de contagios.

#Feluda: All You Need to Know about India’s Newly-Approved #COVID19 Test

#covid19 #coronavirus
#Feluda, a low-cost, indigenously developed testing method that can detect the novel coronavirus accurately in less than 30 minutes, has been approved for commercial use by the Drugs Controller General of India.
#COVID19 tests that are currently being used take longer time for diagnosis, leading to delays. However, Feluda significantly reduces the diagnostic time, which will come in handy considering the nationwide COVID-19 case tally has been consistently rising at an exponential rate.

I’m old enough to remember when Senators attempted, at least in public, to avoid breaking their word. The #SCOTUS confirmation process is broken. #ACB is the jurisprudential inverse of #RBG. But a singular focus on the #SCOTUSnominee is a trap for Dems. twitter.com/i/events/13082…
2. Yes, Dems are angry and engaged, supposedly donating >$161 million through @actblue since #RBG’s passing on Rosh Hashanah.
3. But Dems attacks on #ACB’s faith galvanize the Christian Right and signal contempt for their spiritual identities and aspirations. No word from @WINRED on their donors.

While the risk of in-flight transmission of #coronavirus is relatively less, it seems now proven in studies that it can spread.

Thread :
On a 10-hour London to Hanoi, flight :

A cluster of COVID-19 cases among passengers were detected, affected persons were passengers, crew, and their close contacts.

Traced 217 passengers and crew to their final destinations and interviewed, tested, and quarantined them. 2/n
Among the 16 persons in whom SARS-CoV-2 infection was detected, 12 (75%) were passengers seated in business class along with the only symptomatic person (attack rate 62%).

Seating proximity was strongly associated with increased infection risk. 3/n

1) Authorities confirmed Monday what many suspected: Montreal is now in a second wave with 53 #COVID19 outbreaks. In this thread, I’ll call for more restrictions to lower viral transmission in a city that appears to again have become the epicenter of the #pandemic in Canada.
2) The rapidity of the spread of the #coronavirus in Montreal cannot be overstated. In a just week, the number of #COVID19 outbreaks in city schools has doubled to 14, including at Herzliah High, which has closed until Oct. 5. Outbreaks have also hit 28 workplaces.
3) What’s more, clusters of #COVID19 cases have been observed in two daycares and six eldercare homes. Young workers appear to be driving the transmission of the highly contagious pathogen, a much different situation than during the first wave.
