    Dịch Covid-19 không thể tự trị như bệnh cảm cúm thông thường. Đơn giản là như vậy. Nhất là những người tri thiên mệnh. Rủi ro lớn quá. Tuy nhiên muốn tham gia vào con số tử vong thì dĩ nhiên không ai dám cản trở.

Đốc tờ nói rằng chính đốc tờ đã chứng kiến rất nhiều trường hợp hồn ma bóng quế giao cấu xé với người phàm, số này có lẽ cũng ngang cơ với số bệnh nhân bị nhiễm Covid-19 được đốc tờ chữa bằng HCQ.

    Impressive and… stable doctor!



    Note: There are quite a few evil spirits writing comments to express approval and confidence in the doctor upon watching the evidence of their existence presented by the graduate of Hogwarts School of Medical Witchcraft and Wizardry.

    Dr. Harvey Risch is a distinguished cancer epidemiologist who has opined on the topic of hydroxychloroquine (HCQ) and COVID-19 out-patient therapy. He has written a review article in the American Journal of Epidemiology that cites evidence that he believes supports HCQ use for out-patient infection with SARS-CoV-2. Studies that indicate no effect or harmful effects, Dr. Risch believes, enrolled patients too sick to benefit from HCQ.

    "....For the moment, aside from wearing masks, the team urged: "Keep social distancing, having as few people per room volume as possible....."




    Coronavirus: Humidity key to minimize virus transmission — study

    Dry rooms and air-conditioned indoor spaces hike Covid-viral infection, conclude Indian and German researchers in their meta-study. They're urging optimum humidity standards for building interiors and public transport.



    Relative humidity "strongly influences" the spread of viruses among people indoors, especially in dry rooms. That's the conclusion reached by an Indian-German research team which evaluated 10 mostly recent international studies.

    "The role of humidity seems to be extremely important to the airborne spread of COVID-19 in indoor environments," according to the report, which was also based on findings derived from past tests with similar viruses, H1NI for influenza and MERS-CoV.

    Public buildings should have at least 40% humidity indoors, capped at 60%, to reduce viral-spread risks for occupants, said analysts led by Sumit Kumar Mishra of India's CSIR National Physical Laboratory and Alfred Wiedensohler and Ajit Ahlawat of Germany's Leibniz Institute for Tropospheric Research (TROPOS).

    How humidity affects transmission

    Their report says humidity affects viral spread in three ways: droplet size, how viral-loaded aerosols float for "hours," and stay viral on landing surfaces.

    In humid places, the viral droplet — a solution of salts, water, organics and attached viruses — grows and it falls faster, "providing less chances for other people to breathe in infectious viral droplets."

    But in dry indoor air, micro-droplets shrunk by evaporation become lighter and stay adrift — an "optimal route" for viruses to be "inhaled by other residents, or finally settle on surfaces where they can survive for many days," warns the report.

    Maintaining relative room humidity at between 40% and 60%, "like opening of windows," they say, can also reduce absorption of viruses though a person's nasal passages.

    "Dry air also makes the mucous membranes in our noses dry and more permeable to viruses, said Ahlawat.

    Threat ahead

    The Northern Hemisphere's approaching winter meant higher risks for "millions of people" in heated rooms, warned Wiedensohler because colder outdoor air was typically sucked indoors via air-conditioning systems.

    Heating that inflowing air to a comfortable temperature would "significantly lower the indoor RH (relative humidity), which creates an extremely dangerous situation for indoor residents, particularly during the COVID-19 pandemic," says the paper.

    Citing Singapore and Malaysian studies, they also warned tropical residents to avoid "extreme cooling" systems because resulting dried indoor airflows would also "promote more COVID viability."

    In conclusion, the team said building supervisors and governments would play an "extremely important role" in updating standards.

    "Authorities should include the humidity factor in future indoor guidelines," said CSIR's Mishra.

    "Based on research findings, for future scenarios, setting a minimum RH standard in public buildings" said the report, "will not only reduce the impact of COVID-19, but it will also reduce the impact of further viral outbreaks."

    For the moment, aside from wearing masks, the team urged: "Keep social distancing, having as few people per room volume as possible."

    Global race to buy coronavirus vaccine: What you need to know

    Nations around the world are pledging billions to buy COVID-19 vaccines even before they have proven to be successful. DW explains how advance-purchase deals work and why they are stoking vaccine nationalism concerns.



    Several nations have already agreed to buy millions of doses of vaccines even before they have been approved. Most of the countries, led by the US and the UK, are striking advance-purchase agreements with several drug companies to increase the odds that they have at least one successful vaccine as early as this year.

    The vaccine being developed by British-Swedish drugmaker AstraZeneca and the University of Oxford has so far managed to score the maximum deals.

    What are advance vaccine purchase agreements?

    Advance Vaccine Purchase Agreements (APA) or Advance Market Commitments (AMC) are deals that governments, international organizations, private companies, or public insurers strike with vaccine makers to procure a substantial number of doses of vaccines — even before they are ready. The idea is to incentivize vaccine companies to produce certain vaccines that they feel may not be profitable enough or may not have a big enough market. The agreements give drugmakers security to invest in R&D and scale up the production of vaccines.

    APAs are especially crucial for poorer nations, which often see pharmaceutical giants look the other way when it comes to spending on infectious disease outbreaks in low-middle income countries. Bulk vaccine purchases by governments and international organizations also help bring down their price.

    The terms of APAs vary from deal to deal. In many cases, the payments to vaccine companies are contingent on the success of their vaccine, as is the case in most of the recent government deals to procure coronavirus vaccines. There are also instances when the investments are not subject to the clinical success of the vaccine, so if a vaccine does not get regulatory approval, both the sponsor and the drugmaker lose money.

    Several countries and organizations, such as the United States and Geneva-based Gavi vaccine alliance, are investing in the so-called at-risk manufacturing of COVID-19 vaccines, which means they are funding vaccine makers to start mass-producing vaccines while they are still being evaluated in clinical trials.

    "If we don't undertake 'at risk manufacturing,' then when the vaccine is successful in clinical trials, there will be a long delay (estimated to be almost a year) from the time of that clinical success to the scaling-up of production," a Gavi spokesperson told DW.

    Vaccine development and manufacturing typically occur sequentially, and it can take an average of seven to 20 years for a vaccine to be developed and scaled up for widespread use. Gavi expects upfront payments to help compress the COVID-19 vaccine development time frame to 12-18 months by securing raw materials and kick-starting manufacturing scale-up and vaccine production during development.

    Which countries have struck agreements for COVID-19 vaccines?

    The US is by far the most aggressive when it comes to scoring deals for coronavirus vaccines. The country, the worst hit by the pandemic, has committed nearly $10 billion (€8.5 billion) to procure at least 700 million doses of vaccines.

    That sum includes $1.2 billion earmarked for at least 300 million doses from AstraZeneca, $1.5 billion for 100 million doses of Moderna's mRNA-1273 vaccine, $1.9 billion for 100 million doses from Pfizer and German startup BioNTech, $2.1 billion for 100 million doses from Sanofi and GlaxoSmithKline (GSK), as well as $1.6 billion to be spent on 100 million doses from Maryland biotechnology company Novavax.

    The United Kingdom is next in line. The country, which has the highest coronavirus death toll of any European country, has secured at least 250 million doses from various vaccine makers — nearly four times its population of 66 million and caused by uncertainty over which of the experimental vaccines may work. The UK has deals to procure vaccines from Sanofi and GSK, Pfizer and BioNTech, and AstraZeneca.

    The European Union, which came late to the party, has agreed to buy at least 300 million doses of AstraZeneca's vaccine in its first such advance-purchase deal. The bloc is in talks with Johnson & Johnson, Sanofi and GSK, Pfizer, and Moderna for their vaccines under development. The European Commission said on Thursday it was in advanced talks with Curevac, partly owned by the German government, regarding the purchase of 225 million doses of its vaccine.

    Some other rich countries, such as Japan and Australia, have also signed advance-purchasing deals. Tokyo has secured 120 million doses from Pfizer and BioNTech, while Canberra has agreed to procure AstraZeneca's vaccine. China, so far, seems to be betting on homegrown vaccines, at least three of which are in late-stage clinical trials.

    Russia has approved its locally developed COVID-19 vaccine, Sputnik V, even before the completion of its phase-three trial that involves testing on thousands of people. But that's not deterring governments from signing up for it. Vietnam is reported to have registered to buy 50 million to 150 million doses of the vaccine. Kirill Dmitriev, head of the investment fund that financed the development of the vaccine has said that there are already preorders for 1 billion doses of the vaccine from some 20 countries.

    Why are these deals stoking vaccine nationalism concerns?

    The aggressive deal-making by rich countries to secure vaccines for their people has led to concerns that the poorer nations may be left behind. The World Health Organization has warned against this "my nation first" approach.

    "Vaccine nationalism is not good, it will not help us," WHO chief Tedros Adhanom Ghebreyesus said earlier this month. "For the world to recover faster, it has to recover together, because it's a globalized world: the economies are intertwined. Part of the world or a few countries cannot be a safe haven and recover."

    Gavi has created the COVID-19 Vaccine Global Access (COVAX) facility to ensure fair global access to coronavirus vaccines. The facility would enter into advance-purchase agreements with pharmaceutical companies to secure vaccines. More than 150 countries — 75 of which would finance the vaccines from their own public finance budgets while the rest would be supported by donations — have signed up so far. Less than half of the OECD countries have joined the facility and they don't include the US, Germany, or France.

    The European Commission has urged EU states not to join the WHO-backed facility, Reuters reported. The Commission has however said vaccines bought from AstraZeneca, and from other vaccine makers, could be donated to poorer countries, the news agency said.

    The facility has struck a deal to procure 300 million doses from AstraZeneca. It is also providing upfront capital to India's Serum Institute, the world's largest vaccine maker by volume, to accelerate the manufacture and delivery of up to 100 million doses.

    "Both fully self-financing and AMC-eligible [COVAX Advance Market Commitment] countries will receive an equal dedicated proportion of vaccine supply, in tranches, as soon as doses become available to the Facility — in order to protect high priority groups within their populations," the Gavi spokesperson said.

    Hong Kong reports 'first case' of virus reinfection


    Hong Kong scientists are reporting the case of a healthy man in his 30s who became reinfected with coronavirus four and a half months after his first bout.

    They say genome sequencing shows the two strains of the virus are "clearly different", making it the world's first proven case of reinfection.

    The World Health Organization warns it is important not to jump to conclusions based on the case of one patient.

    And experts say reinfections may be rare and not necessarily serious.

    There have been more than 23 million cases of coronavirus infection around the world.

    Those infected develop an immune response as their bodies fight off the virus which helps to protect them against it returning.

    The strongest immune response has been found in the most seriously ill patients.

    But it is still not clear how strong this protection or immunity is - or how long it lasts.

    And the World Health Organization said larger studies over time of people who had previously had coronavirus were needed to find out more.

    This report, by the University of Hong Kong, due to be published in Clinical Infectious Diseases, says the man spent 14 days in hospital before recovering from the virus but then, despite having no further symptoms, tested positive for the virus a second time, following a saliva test during airport screening.

    "This is a very rare example of reinfection," said Brendan Wren, professor of microbial pathogenesis, at London School of Hygiene and Tropical Medicine.

    "And it should not negate the global drive to develop Covid-19 vaccines.

    "It is to be expected that the virus will naturally mutate over time."

    Dr Jeffrey Barrett, senior scientific consultant for the Covid-19 genome project at the Wellcome Sanger Institute, said: "Given the number of global infections to date, seeing one case of reinfection is not that surprising even if it is a very rare occurrence.

    "It may be that second infections, when they do occur, are not serious - though we don't know whether this person was infectious during their second episode."

    Prof Paul Hunter, from the University of East Anglia, said more information about this and other cases of reinfection was needed "before we can really understand the implications".

    Man who believed virus was hoax loses wife to Covid-19

    By Marianna Spring Specialist disinformation reporter, BBC News


    Brian with his wife Erin, who passed away this month

    A Florida taxi driver, who believed false claims that coronavirus was a hoax, has lost his wife to Covid-19.

    Brian Lee Hitchens and his wife, Erin, had read claims online that the virus was fabricated, linked to 5G or similar to the flu.

    The couple didn't follow health guidance or seek help when they fell ill in early May. Brian recovered but his 46-year-old wife became critically ill and died this month from heart problems linked to the virus.

    Brian spoke to the BBC in July as part of an investigation into the human cost of coronavirus misinformation. At the time, his wife was on a ventilator in hospital.

    Deadly conspiracy theories

    Erin, a pastor in Florida, had existing health problems - she suffered from asthma and a sleeping disorder.

    Her husband explained that the couple did not follow health guidance at the start of the pandemic because of the false claims they had seen online.

    Brian continued to work as a taxi driver and to collect his wife's medicine without observing social distancing rules or wearing a mask.

    They had also failed to seek help as soon as poBrian told BBC News that he "wished [he'd] listened from the beginning" and hoped his wife would forgive him.

    "This is a real virus that affects people differently. I can't change the past. I can only live in today and make better choices for the future," Brian explained.

    "She's no longer suffering, but in peace. I go through times missing her, but I know she's in a better place."

    'This thing is real'

    Brian said he and his wife didn't have one firm belief about Covid-19. Instead, they switched between thinking the virus was a hoax, linked to 5G technology, or a real, but mild ailment. They came across these theories on Facebook.

    "We thought the government was using it to distract us," Brian explained, "or it was to do with 5G."

    But after the couple fell ill with the virus in May, Brian took to Facebook in a viral post to explain that he'd been misled by what he'd seen online about the virus.

    "If you have to go out please use wisdom and don't be foolish like I was so the same thing won't happen to you like it happened to me and my wife," he wrote. ssible when they fell ill in May and were both subsequently diagnosed with Covid-19.

    In May, a BBC team tracking coronavirus misinformation found links to assaults, arson and deaths.

    Doctors and experts have warned that the potential for indirect harm caused by rumours, conspiracy theories and bad health information online remains huge - especially as anti-vaccination conspiracies are being spread on social media.

    While social media companies have made attempts to tackle misinformation about coronavirus on their platforms, critics argue that more needs to be done in the coming months.

    A Facebook spokesperson told the BBC: "We don't allow harmful misinformation on our platforms and between April and June we removed more than seven million pieces of harmful Covid-19 misinformation, including claims relating to false cures or suggestions that social distancing is ineffective."

    Oxford University vaccine trial paused after participant falls ill



    Final clinical trials for a coronavirus vaccine, developed by AstraZeneca and Oxford University, have been put on hold after a participant had an adverse reaction in the UK.



    AstraZeneca described it as a "routine" pause in the case of "an unexplained illness".

    The outcome of vaccine trials is being closely watched around the world.

    The AstraZeneca-Oxford University vaccine is seen as a strong contender among dozens being developed globally.

    Hopes have been high that the vaccine might be one of the first to come on the market, following successful phase 1 and 2 testing.

    Its move to Phase 3 testing in recent weeks has involved some 30,000 participants in the US as well as in the UK, Brazil and South Africa. Phase 3 trials in vaccines often involve thousands of participants and can last several years.

    What have the developers said?


    All international trial sites have now been put on pause while an independent investigation reviews the safety data before regulators decide whether the trial can restart, the BBC's Medical Editor Fergus Walsh reports.

    "In large trials, illnesses will happen by chance but must be independently reviewed to check this carefully", an Oxford University spokesperson said.

    This is the second time the Oxford coronavirus vaccine trial has been put on hold, our correspondent notes. Such events are routine in major trials, and happen any time a volunteer is admitted to hospital when the cause of their illness is not immediately apparent.

    It is thought the trials could resume in a matter of days.

    Stat News, the health website which first broke the story, said details of the UK participant's adverse reaction were not immediately known, but quoted a source as saying they were expected to recover.

    Where are we in the search for a vaccine?

    US President Donald Trump has said he wants a vaccine available in the US before 3 November's election, but his comments have raised fears that politics may be prioritised over safety in the rush for a vaccine.

    On Tuesday, a group of nine Covid-19 vaccine developers sought to reassure the public by announcing a "historic pledge" to uphold scientific and ethical standards in the search for a vaccine.

    AstraZeneca is among the nine firms who signed up to the pledge to only apply for regulatory approval after vaccines have gone through three phases of clinical study.

    Industry giants Johnson & Johnson, BioNTech, GlaxoSmithKline, Pfizer, Merk, Moderna, Sanofi and Novavax are the other signatories.

    They pledged to "always make the safety and well-being of vaccinated individuals our top priority".

    The World Health Organization (WHO) says nearly 180 vaccine candidates are being tested around the world but none has yet completed clinical trials.

    The organisation has said it does not expect a vaccine to meet its efficacy and safety guidelines in order to be approved this year because of the time it takes to test them safely.

    Similar sentiments have been shared by Thomas Cueni, director-general of the International Federation of Pharmaceutical Manufacturers. The industry body represents the companies that signed the pledge.

    Despite this, China and Russia have begun inoculating some key workers with domestically developed vaccines. All of them are still listed by the WHO as being in clinical trials.

    Meanwhile, the US national regulator, the Food and Drug Administration (FDA), has suggested that coronavirus vaccines may be approved before completing a third phase of clinical trials.

    Last week it also emerged that the US Centers for Disease Control and Prevention had urged states to consider waiving certain requirements in order to be ready to distribute a potential vaccine by 1 November - two days before the 3 November presidential election.

    Although President Trump has hinted that a vaccine might be available before the election, his Democratic rival Joe Biden has expressed scepticism that Mr Trump will listen to scientists and implement a transparent process.

    Helsinki airport trials sniffer dogs as Covid-19 detectors



    Reuters - The dogs started working at the airport earlier this week

    Sniffer dogs are a familiar sight at airports all over the world, where border agents use them to detect illegal substances and contraband.
    Now some dogs are using their noses for a different purpose - coronavirus.


    Dogs specially trained to detect Covid-19 have this week started sniffing passengers as part of a trial at Finland's Helsinki-Vantaa airport.
    Volunteers are training a team of 15 dogs and 10 instructors for the research programme.

    The dogs can detect coronavirus in humans five days before they develop symptoms, Anna Hielm-Bjorkman, the University of Helsinki professor who is running the trial, told Reuters news agency.
    "They are very good [at detecting coronavirus]. We come close to 100% sensitivity," she said.


    EPA - Arriving passengers are asked to wipe their necks with cloths


    Reuters - The samples are then placed in cans and put in front of dogs to sniff


    Reuters - Canine coronavirus tests take minutes to complete

    Passengers wipe their necks with cloths, which are then placed in a can and put in front of dogs to sniff. A canine test can deliver a result within minutes.
    But while the trial has shown early promise, more research needs to be done to prove the efficiency of canine testing. At the moment, passengers who take part in the trial are also instructed to take a swab to confirm the result.


    Reuters - Sniffer dogs Miika (left) and Titta started their training more than three weeks ago

    Vantaa Deputy Mayor Timo Aronkyto said it was possible that the dogs could in future "go around passengers in a similar way to customs dogs".
