BharatBiotech,which is into developing Covaxin, a vaccine candidate for COVID-19,on Friday said it has successfully completed interim analysis of Phase I and II trials and is initiating Phase-III trials in 26,000 participants.
You can't go by daily testing values, those dip significantly during weekends and rise to catch up during the week. There was a week when they went to nearly 1.5 million, catching up from a low of 750,000 during the weekend. The 7-day average is currently 1.06 million. Divide the 7-day avg. of case counts by 7-day avg. of testing for a more accurate figure - currently slightly higher than 5%.saip wrote:...
...or use masks and social distancing. This has proven to be effective in drawing down the numbers of infection in many states including the worst-hit NY state, which was in a terrible abyss in Apr/MAy and there were able to pull out of it without a vaccine. The question would be: can we do anything to prevent its spread while we wait for a vaccine. The answer is 'yes'.chola wrote:Well, we just hit a third peak in the US. Over 81K new cases on Friday.
It looks we will not have things under control over here until a vaccine.
I know. That is why some people doubting the team is so perplexing to me. In any case, whether their predictions turn out to be correct or not depends on how people on the ground are implementing measures. Both the officials and more importantly citizens themselves are responsible to make the prediction becomes a reality.Amber G. wrote:Prof M.

Prof. Manindra Agrawal was attacked on Twitter a few weeks back. I didn't realize that he is on this team along with Prof. M. Vidyasagar. Maybe that was the reason why he was attacked. The attack originated from a Twitter handle whose DP claims some NGO or some such "common good" worker.hnair wrote:I fully expect scare mongering around Deepavali super-clusters, “PM Modi believes in pseudo-science offered by right wing professors” etc by pharma/media

Original is reported here.Sensor Rapidly Detects COVID-19 Infection Status, Severity, Immunity (OCTOBER 26, 2020)
A new type of multiplexed test with a low-cost sensor may enable the at-home diagnosis of a COVID infection through rapid analysis of small volumes of saliva or blood, without the involvement of a medical professional, in less than 10 minutes.
The sensors are made of graphene, a sheet-like form of carbon. A plastic sheet etched with a laser generates a 3D graphene structure with tiny pores. Those pores create a large amount of surface area on the sensor, which makes it sensitive enough to detect, with high accuracy, compounds that are only present in very small amounts. In this sensor, the graphene structures are coupled with antibodies, immune system molecules that are sensitive to specific proteins, like those on the surface of a COVID virus, for example.

Now, Caltech researchers have developed a new type of multiplexed test (a test that combines multiple kinds of data) with a low-cost sensor that may enable the at-home diagnosis of a COVID infection through rapid analysis of small volumes of saliva or blood, without the involvement of a medical professional, in less than 10 minutes.
The research was conducted in the lab of Wei Gao, assistant professor in the Andrew and Peggy Cherng department of medical engineering. Previously, Gao and his team have developed wireless sensors that can monitor conditions such as gout, as well as stress levels, through the detection of extremely low levels of specific compounds in blood, saliva, or sweat.

@Cain Marko - that correlation seems to exist for all the countries I tried. Where the data are clean, like USA, Japan, etc., it is easy to estimate the lag factor just by looking at the peak of that "Corr. Coef. vs. lag factor" plot. By "clean," I mean - distinct peaks in the death counts and positivity fractions. The USA has three waves, which makes for good confidence in that correlation.sudarshan wrote:I'll have to think of what correlates with case numbers.

NEW DELHI: The Centre expressed concern over five states — Kerala, West Bengal, Maharashtra, Karnataka and Delhi — accounting for almost 50% of fresh cases of Covid detected on Monday even as active cases now stand at 6.25 lakh. Of this, 35% are from only 18 districts.
In the continuing fight against the novel Coronavirus, researchers have now identified a drug with the potential to provide treatment for Covid-19 close to a year after it turned into a pandemic.
The study, published in the journal Cells, found that the approved protease inhibitor aprotinin displayed activity against SARS-CoV-2, the coronavirus that causes Covid-19, in concentrations that are achieved in patients.
According to the researchers, aprotinin aerosols are approved in Russia for the treatment of influenza and could be readily tested for the treatment of Covid-19.
An approved aprotinin aerosol may have the potential for the early local control of SARS-CoV-2 replication and the prevention of Covid-19 progression to a severe, systemic disease," the study authors noted.
While one can argue endlessly if US could've/should've handled the crisis better truth be told most of the world-class, free-for-all social medicine European countries too are seeing a dramatic rise in cases. Adjusted to per capita the cases are within 10% to 15% of US either higher or lower. Take France for ex : ~5k cases/day during the peak months of Mar and Apr, today it is close to 40k cases/day ! Spain ~10k/day in Mar and around 25k now, Belgium ~1500/day in March and a whooping ~20k+/day now ! You'll see that the cases per day in Europe is exponentially higher compared to their Mar/Apr peak, comparatively US has done a far better job containing the rise in cases in 2nd (or is it the 3rd ?) wave. Also, just cases alone don't mean much if majority are mildly symptomatic or asymptomatic , as in Eur, in US too its the young people who are driving the cases higher, so the CFR compared to the peak months is dramatically low. For ex: In Belgium where cases are around 15 times higher compared to their March peak, the deaths are half of what it was in March, you'll see similar trends in Italy, Spain, France, UK etc.chola wrote:@Amber, it is unbelievable how quickly we have lost control again in the states.
