The confirmed diagnoses in JHU's dashboard are rising at 3-4k/day. It should be more exponential. The rate seems to be limited and I'd give high probability it's because of what the article describes. Link to comment Share on other sites More sharing options...

On Tuesday, 262 people left hospitals nationwide. The number of suspected cases has dropped for two days in a row. Officials said they were tracking 3,971 suspected cases, compared with 5,173 cases the day before. It may not be that clear. The increase in cured per day also relates to the lag time between admission and discharge. Today's cured rate will track the rapid increase in admissions roughly 2-3 weeks prior. The detailed paper on forcasting referenced by WaveHunter gives a better picture of how the whole process is modelled, particularity the sharp peak in April/May.

More specifically, is it a symptomatic assessment, or is it actually being confirmed that there is no viral load (i.e.: the virus is not in the body any longer). That is not being made clear at all from any sources I've seen. Does anyone else have any better information? 1 Link to comment Share on other sites More sharing options...

Now we've got this to possibly look forward to ???? Still though, some viruses do not do well at all in warmer more humid weather. Remember that right now in China it is very cold. SARS disappeared in the northern summer of 2003 and has not reappeared significantly since. The seasonality of influenza and other respiratory viruses in temperate countries is thought to be related to factors that affect infectiousness (person to person spread) such as the dryness of the air, ambient air temperature and possibly ultraviolet solar radiation. The Thai weather may end up being our saving grace ???? Edited February 5, 2020 by WaveHunter 2 Link to comment Share on other sites More sharing options...

This is for the UN as a whole not WHO specifically: https://qz.com/1396994/where-does-the-un-get-its-money-a-simple-explanation-of-a-complex-system/ (SEP 2019) That may be true but money is money, and China has a reputation for using money in this manner, and doing it in an extremely effective way. It is simply an extension of their "Belts and Roads" initiative, which, though it may sound noble and good on the surface, is really a very well-conceived and very effective way that China is influencing foreign governments and institutions all around the world to bend to their will. Irregardless of the monetary incentive, how can anyone rationally explain WHO's position of finally declaring this crisis as a global emergency, yet emphatically and specifically stating that travel and trade should not be restricted nor should any other actions be taken "against" China, and anyone who thinks it should is making a big mistake (The Director-General's words, not mine). Using the word "against" is intentionally implying that to do so would be to punish the Chinese (i.e.; to act in a racist manner towards China.) That statement by the Director-General has a highly charged political statement that had nothing whatsoever to do with health issues. The WHO's current position makes absolutely no sense at all, given the severity of the current situation. Their mission is to promote the safety and well being of the global community, NOT the economic well being of China, which right now, are diametrically opposed to one another. Yet that is exactly what the WHO is doing; placing greater concern with the economic well being of China, than the health and safety of the global community! Please explain, if you can, how my reasoning is incorrect. Edited February 5, 2020 by WaveHunter 3 Link to comment Share on other sites More sharing options...

WaveHunter Posted February 5, 2020 Share Posted February 5, 2020 (edited) 7 hours ago, TallGuyJohninBKK said: WH, was their projection of the April peak just for China alone, or for the world? If for China alone, then all the other places and countries, including Thailand, are going to have presumably sequentially longer times to peak and resolution, because they were later starters in the process, so to speak. Just for Wuhan City; Other seeded cities in China (and all provinces) would lag by about two weeks. The April date is assuming that containment efforts are not effective, and the peak is caused by "herd immunity effect". So far, it looks like containment efforts within China are not proving to be very effective considering that all provinces are now affected and there is a lot of city seeding in every major city. The containment is not expected to be very effective so April is probably the date for peak in Wuhan and a few weeks later for the rest of China, but if it proves effective to some degree, the peak dates could occur earlier. It is all in the reports at Lancet. As for international locations, there really are no uncontained outbreaks yet, but there are dozens of confirmed cases all over the world as we all know. Most seems to be well contained, so theoretically there could be no spread (and thus no peak to be concerned with), but then there is the problem of infected but unconfirmed cases. Over 5 million people were able to leave Wuhan before the city was locked down. Many were able to travel overseas before any sort of screening was in place, so they are the "wild card" right now in how the pandemic plays out over the next week I think. It is a wait-and see type of thing right now of whether or not this thing blows up globally, I guess. Hopefully it will not!

overherebc Posted February 5, 2020 Share Posted February 5, 2020 (edited) Mostly questions. The other day I'm sure I heard, uk news, the virus has not mutated. Later samples been exactly the same as initial samples. SARS and MERS, from memory did mutate and started to lose some of their impact. As I started by saying, questions, not statements by me, could this new virus not 'need' to mutate to ensure its own survival, ie it doesn't so far have any obvious weak points that can be attacked.

All I really know about methylprednisolone use for nCoV patients is from a Lancet article I read. It is a corticosteroid that was given as part of a combined regimen if severe community-acquired pneumonia was diagnosed. It was given in combination with antibiotic treatments. I may be wrong but I do not think the use of methylprednisolone or antibiotics is to address the virus directly but to address associated inflammation brought on by pneumonia. However, I recently read an article in Nature that discusses two drugs that may be proving to be effective at dealing with nCoV and I'll do a post on them shortly.

englishoak Posted February 6, 2020 Share Posted February 6, 2020 (edited) A Chinese newborn has been diagnosed with the new coronavirus just 30 hours after birth, the youngest case recorded so far, state media said. The baby's mother tested positive before she gave birth. It is unclear how the disease was transmitted. https://www.bbc.co.uk/news/world-asia-china-51395655 Medical experts say it could be a case of mother-to-child transmission - where the infection was contracted in the womb or it could have contracted it after birth in the usual close contact manner. This could be a BiG complication because babies cant contract the Flu virus from mother to child transmission, if it turns out the baby was born with it then we have just jumped the shark and in bigger doo doo than current assessments predict.

WaveHunter Posted February 6, 2020 Share Posted February 6, 2020 (edited) I read a fascinating letter to the editor on the Nature.com website published 04 February concerning two antiviral drugs that may prove to inhibit the novel coronavirus (2019-nCoV), so I thought I'd share here. The link is https://www.nature.com/articles/s41422-020-0282-0 The drugs are Remdesivir and Chloroquine. The findings reveal that remdesivir and chloroquine are highly effective in the control of 2019-nCoV infection in vitro (in a petri dish), and seem to have actually worked in-vivo (in human)...in the man in Washington State who has recovered. Remdesivir was seriously looked at during the SARS, MERS, and Ebola outbreak, and while it worked in-vitro, it did not work in-vivo. They now have tried it In-Vivo with the man in Washington State in critical condition with nCoV, and it appears that it may have worked since he felt better within a day, and seems to have fully recovered after a few more days (no viral load detected). Of course without controlled random trials that can't yet say it actually works so formal trials are now about to begin. The way it works is that once the virus enters a healthy cell, Remdesivir prevents the virus from replicating itself. Science-Speak: The way nCov works is that once the virus is able to enter a healthy cell, the virus tries to use the healthy cell's replication machinery to replicate itself by changing the RNA sequence of the healthy cell from ATGCTT to AUGCUU, let's say. What Remdesivir does is puts an artificial "A" in the healthy cell so when the virus polymerization begins and hits the Remdesivir's "A", the virus' replication process can not go beyond the "A" and the replication process is halted. I'm grossly simplifying this just to make it clear (and probably doing a poor job of it) but I think you get the idea. Remdesivir has already been tested on humans and its' safety is known. Even though it is not FDA approved, scientist felt it was proper to use it anyway under the new "compassionate use" laws passed by the Trump Administration. Even though it worked, it is still not "proven" to work in-vivo. Effectiveness must be determined by randomized, placebo controlled trials which will now be conducted in China, and it should be known by April if it works. Chloroquine has been around for years and used effectively in Malaria. It has also been found to be promising in treating nCoV. The way it works is in raising the pH of lysosomes thus preventing the virus from merging to the healthy cell. There are many other drugs being tested as well. In Thailand for instance, researchers are exploring the use of AIDS drugs (lopinavir and ritonavir) in human cases of nCoV with apparent success. Of course all of these drugs, as promising as they sound, they must go through randomized, placebo controlled trials to determine true effectiveness, but that seems to be what is now about to happen in China, so this is incredibly encouraging!

I'm in no way a medical person, just someone asking questions. It would seem that mutations could be either a good or bad thing; which I guess goes without saying really. As for 'weak" points, over time, as more and more people get the virus and recover, they will be more immune to a second infection so this "herd immunity" effect will naturally lower the infectiousness of nCoV. It's estimated this will lower infectiousness by about 50%, giving it an R0 (R-naught) of 1.3, which means 1 index case will only infect one healthy person instead of what it is now which is 1 index case infecting 3 persons, each of which then goes on to infect three more people, and so on. It is estimated that even if containment efforts have a minimal impact on the additional outbreaks within China right now (which appears to be the case since it has spread to all provinces and major cities), the herd-immunity effect will cause the outbreak to peak by April, in Wuhan, and a couple of weeks later in other parts of China. Also, there are anti-viral drugs (I posted about this earliest this morning) that appear to be effective and are going to be in clinical trials in China shortly that do in fact exploit the "weak" points and curtail the virus's ability to replicate. These are drugs that have already been developed, safe for use in humans, and proved successful in-vitro (in petri dishes) for SARS, MERS, and Ebola, though they did not work in-vivo (in humans), but in the case of n-CoV, they appear to work in humans. BTW, I'm not a doctor or scientist either but I read The Lancet (probably the most well respected peer-reviewed medical journal in the world) and Nature.com, another science-based and highly regarded source of information on this virus, and this is where all of what I am relaying comes from. These are very trustworthy sources, unlike a lot of garbage floating around in the mass media, on the internet, and in social media right now.

rabas Posted February 6, 2020 Share Posted February 6, 2020 (edited) There will likely be many announcements of cures based on various mixtures of known drugs. This was also true during the SARS epidemic. These were later reviewed in the medical literature and while a few looked promising, none were found to be cures. HIV drugs came to light at that time. Here are a couple more for the new nCoV2019. Another thread was bashing Thailand for claiming a cocktail of anti virals cured the first Thai patient, a severely ill woman. Later the Chinese announced similar findings, but note the Thai used a live patient, the Chinese did it in a beaker. China, Reuters:Oil-jumps-3-on-reports-of-effective-coronavirus-drug China’s Changjiang Daily newspaper reported on Tuesday (Feb 4) that a team of researchers led by Zhejiang University Professor Li Lanjuan had found that drugs Arbidol and Darunavir can inhibit the virus in vitro cell experiments. What are these drugs? 1. Arbidol is a Russian anti-viral drug similar in use to Tamiflu (Oseltamivir) it can prevent the virus from entering cells, Tamiflu stops it from exiting. 2. Darunavir is a well known HIV drug, often used in combo with others. The Thai used a mixture of HIV drugs and Tamiflu to cure the lady. So these trials were both HIV drugs + flu antivirals. Expect more but good luck buying anything announced as a cure. Edited February 6, 2020 by rabas Link to comment Share on other sites More sharing options...
