62 Nations Back Australia’s Demand for Chinese Coronavirus Probe

Simon Kent

May 17, 2020

Australia’s demand for an investigation into the World Health Organization’s bungled response to the deadly Chinese coronavirus pandemic now has the backing of 62 nations, all willing to support a draft resolution addressing the issue Tuesday at a meeting of the World Health Assembly.

Australia’s motion includes more robust language than that contained in an earlier watered down European Union version. It is supported by key nations including India, Japan, the UK, Canada, New Zealand, Indonesia, Russia, Mexico and Brazil, and all 27 E.U. member states amongst others.

The Australians have also been among the most outspoken critics of China’s dangerous refusal to close the live animal “wet markets” seen as spawning grounds for the viral pandemic, and of the W.H.O.’s baffling endorsement of their reopening:


Our immune systems weaken with age. Researchers want to solve that.

The ebbing of resistance to infectious disease with age is particularly clear when looking at studies of vaccines. During 2018-2019, for example, the seasonal flu vaccine was effective for roughly 3 of 5 children 17 and younger, according to the Centers for Disease Control and Prevention. The same vaccine was effective for only about 1 of 4 adults 50 and older.

Scientists have rushed to start trials for a vaccine against coronavirus. But even when they succeed in developing an effective one, University of Pennsylvania immunologist Michael Cancro worries that any coronavirus vaccine may be less effective for older adults — just as current vaccines are for other diseases.



What happens if a coronavirus vaccine is never developed? It has happened before

By Rob Picheta, CNN

Updated 9:39 AM ET, Sun May 3, 2020

But there is another, worst-case possibility: that no vaccine is ever developed. In this outcome, the public's hopes are repeatedly raised and then dashed, as various proposed solutions fall before the final hurdle.

Instead of wiping out Covid-19, societies may instead learn to live with it. Cities would slowly open and some freedoms will be returned, but on a short leash, if experts' recommendations are followed. Testing and physical tracing will become part of our lives in the short term, but in many countries, an abrupt instruction to self-isolate could come at any time. Treatments may be developed -- but outbreaks of the disease could still occur each year, and the global death toll would continue to tick upwards.

"We've never accelerated a vaccine in a year to 18 months," Dr. Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine in Houston, tells CNN. "It doesn't mean it's impossible, but it will be quite a heroic achievement.

However, it is the testing process -- not the development -- that holds up and often scuppers the production of vaccines, adds Hotez, who worked on a vaccine to protect against SARS. "The hard part is showing you can prove that it works and it's safe."

Virus Likely to Keep Coming Back Each Year, Say Top Chinese Scientists Bloomberg News

April 27, 2020

Chinese scientists say the novel coronavirus will not be eradicated, adding to a growing consensus around the world that the pathogen will likely return in waves like the flu.

It’s unlikely the new virus will disappear the way its close cousin SARS did 17 years ago, as it infects some people without causing obvious symptoms like fever. This group of so-called asymptomatic carriers makes it hard to fully contain transmission as they can spread the virus undetected, a group of Chinese viral and medical researchers told reporters in Beijing at a briefing Monday.


1.  COVID-19 shares about 86% of its genome sequence with SARS. It is therefore designated SARS-CoV-2. This novel coronavirus is therefore likely to spread until a vaccine(s) are developed in about a year.

2.   COVID-19 has mutated genes of HIV which has no vaccine. This may imply no vaccine will be 100% effective.

3.   It is likely that COVID-19 will mutate in a year's time. There is debate among scientists whether or not a virus is living. Basically, life is defined as something that reproduces and evolves over a period of time. It may be said therefore, at this point, that COVID-19 is not alive, but once it evolves or mutates one might say that it is alive.


Report: Russian Doctor Falls Out Window During Tense Coronavirus Argument

Ben Kew

April 27, 2020

A top Russian doctor plunged 50 feet from her office window during a government conference call on Saturday after being told her hospital would have to take in Chinese coronavirus patients without the necessary personal protective equipment (PPE), according to local media reports.

Dr. Yelena Nepomnyashchaya, 47, reportedly objected to plans proposed by the regional Minister of Health Boris Nemik to give 80 beds to coronavirus patients because of an “acute shortage” of PPE for her hospital’s doctors and nurses.

The mother-of-two, who runs the Krasnoyarsk Regional Hospital for War Veterans in the Krasnoyarsk region of Siberia, fell from the building as the discussion ensued.

As in most countries, the issue of PPE shortages has caused conflict within Russia’s medical community, with several top doctors quitting their jobs in protest. This anger has been exacerbated by the fact that Moscow is preparing to send another 40-ton shipment of medicine to the Maduro regime in Venezuela, which relies heavily on the Putin regime for its survival.

This type of political assassination is called "defenestration".

Prof. Elena Musikhina was afraid she would either disappear or be killed in this region of Siberia.


Yayoi Kusama orders coronavirus to 'Disappear from this earth' in a new poem

April 16, 2020

Though it glistens just out of reach, I continue to pray for hope to shine through Its glimmer lighting our way

This long awaited great cosmic glow Now that we find ourselves on the dark side of the world The gods will be there to strengthen the hope we have spread throughout the universe

For those left behind, each person's story and that of their loved ones It is time to seek a hymn of love for our souls In the midst of this historic menace, a brief burst of light points to the future Let us joyfully sing this song of a splendid future Let's go

Embraced in deep love and the efforts of people all over the world Now is the time to overcome, to bring peace We gathered for love and I hope to fulfil that desire The time has come to fight and overcome our unhappiness

To COVID-19 that stands in our way I say Disappear from this earth We shall fight We shall fight this terrible monster

Now is the time for people all over the world to stand up My deep gratitude goes to all those who are already fighting.

MPs summon China-owned firm execs over security concerns

Simon Jack

April 14, 2020

Speaking to the BBC, Tom Tugendhat, the chair of the Foreign Affairs Select Committee said he was concerned that technology developed by Imagination Technologies, based in Hertfordshire, could be used to fine tune the design of so-called "backdoors" into strategically important digital infrastructure.

Imagination Technologies was acquired by a US-based but Chinese state-owned investment firm called Canyon Bridge in September 2017, which is in turn owned by a Chinese state-owned investment fund called China Reform. Mr Tugendhat said Theresa May's government approved the acquisition on the basis that Canyon Bridge was licensed and regulated by US law. Since then it has moved its headquarters to the Cayman Islands and as such is no longer a US-controlled entity.

The Coronavirus Trade-Off That Won’t Go Away


Clive Crook

March 25, 2020

Amid this extreme uncertainty, a crucial trade-off persists – between the steps you take now to save lives and the damage those steps will do to the economy. At first sight, in the spirit of “just do everything,” one longs to deny this trade-off: Governments should move instantly to save as many lives as possible, while reducing the economic damage as far as they can. This thinking sustains the view that hesitating to adopt “lockdowns” in many Western countries – the initial preference for “mitigation” over “suppression” – was a grave mistake. The truth is more complicated.


Complete Story



David Da-i Ho (Chinese: 何大一; born November 3, 1952) is a Taiwanese-American doctor and HIV/AIDS researcher who has made many scientific contributions to the understanding and treatment of HIV infection.

His group was the first to demonstrate protective efficacy of a long-acting antiretroviral drug as pre-exposure prophylaxis in rhesus macaques. In fact, one such agent, cabotegravir, has been advanced into Phase-3 efficacy trials in high-risk populations, in collaboration with GlaxoSmithKline. In parallel, Dr. Ho's group has also engineered exquisitely potent antibodies that neutralize divergent strains of HIV. The most promising neutralizing agent is a bispecific monoclonal antibody that entered a first-in-human clinical trial in 2019 with the support of the Bill & Melinda Gates Foundation. The Ho Lab is funded by two NIH grants to pursue the use of engineered antibodies to purge the viral latent reservoir as a part of the international HIV cure effort. Currently, the Ho lab is funded by the Jack Ma Foundation to work on coronavirus projects.

Farage: Coronavirus Exposes Western Supply Chain’s Dependence on China

Nigel Farage has said that the Chinese coronavirus has exposed the West’s dependence on China in its supply chains, and he hopes the pandemic inspires Prime Minister Boris Johnson to reconsider his decision to allow Huawei to help build Britain’s 5G network.

Criticising those who benefit from ties with China, the Brexiteer added: “I have pointed out before that many members of our big business class, of the civil service, and indeed of our political class are increasingly in the pay of China.

“I think what it is showing us is that while the ‘just in time’ supply chain in the global economy may provide us with efficiency in the global economy, it doesn’t provide us with resilience in the global economy. I think that’s something we will need to look at after because it’s clear that now the concept of ‘over there’ does not exist in a global economy, and a disruption in one part will very quickly become a disruption elsewhere,” Former international trade secretary Dr Liam Fox said earlier this month.

The Conservative MP added that the outbreak should prompt the UK to look at making more ourselves — “import substitution” — as well as to reevaluate “the trend to run down stocks and run down warehousing” in order to “increase resilience should we face something like this in the future, which is likely, because pandemics are the norm in human history, not the exception”.


It is much easier to associate the word "china" with the word "chain". China chains.

Infected people without symptoms might be driving the spread of coronavirus more than we realized

Elizabeth Cohen, Senior Medical Correspondent

Updated 3:32 PM ET, Sat March 14, 2020

The role of asymptomatic transmission

Several experts interviewed by CNN said while it's unclear exactly what percentage of the transmission in the outbreak is fueled by people who are obviously sick versus those who have no symptoms or very mild symptoms, it's become clear that transmission by people who are asymptomatic or mildly symptomatic is responsible for more transmission than previously thought.

"We now know that asymptomatic transmission likely [plays] an important role in spreading this virus," said Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota.

Bill Gates, co-chair of the Bill and Melinda Gates Foundation, expressed concern about the spread of the disease by people who haven't yet developed symptoms, or who are only a bit sick. "There is also strong evidence that it can be transmitted by people who are just mildly ill or even presymptomatic. That means COVID-19 will be much harder to contain than the Middle East respiratory syndrome or severe acute respiratory syndrome (SARS), which were spread much less efficiently and only by symptomatic people," he wrote, using the scientific word for the disease caused by the virus.

A study posted Sunday by Belgian and Dutch researchers shows that between 48% and 66% of the 91 people in the Singapore cluster contracted the infection from someone who was pre-symptomatic. Of the 135 people in the Tianjin cluster, between 62% and 77% caught it from someone was pre-symptomatic.


People who are infected but asymptomatic can spread disease efficiently. They are hardy and mobile. They have no reason to avoid crowds or kissing. They don't know they are sick, and no one else does.    NY Times

This article and comment provide one answer as to how COVID-19 spreads. Young people are generally strong and healthy. This means that if they are infected that they might either be asymptomatic or have mild symptoms. However, if they were to infect older people then the situation changes. Generally, the immune system of older people is not as strong. This means that they are easily infected. They are particularly susceptible if they have weakened immune systems. When infected they take much longer to recover. While recovering, of course, they can infect other people. One suspects also that older people retain the virus in their respiratory tract between 20 and 37 days after they have shown signs of recovery. This period is probably much longer than with young people. Therefore, they can infect caregivers and family. All of this means that the fatality rate for older people is higher than young people.

We Predicted a Coronavirus Pandemic. Here’s What Policymakers Could Have Seen Coming.

Last year we ran a disaster scenario shockingly similar to the news now. Here’s what experts realized the world is getting wrong, and how they can fix it.

The news of a highly contagious new virus jumping from China to the U.S. has caught many Americans by surprise. For us, the outbreak was more like déjà vu: Last October, we convened a group of experts to work through what would happen if a global pandemic suddenly hit the world’s population. The disease at the heart of our scenario was a novel and highly transmissible coronavirus.

For our fictional pandemic, we assembled about 20 experts in global health, the biosciences, national security, emergency response and economics at our Washington, D.C., headquarters. The session was designed to stress-test U.S. approaches to global health challenges that could affect national security. As specialists in national security strategic planning, we’ve advised U.S. Cabinet officials, members of Congress, CEOs and other leaders on how to plan for crises before they strike, using realistic but fictional scenarios like this one.

The principal conclusion of our scenario was that leaders simply don’t take health seriously enough as a U.S. national security issue. Congress holds few hearings on the topic, especially in the defense committees, and the White House last year eliminated a top National Security Council position focused on the issue.

Clade X is a day-long pandemic tabletop exercise that simulated a series of National Security Council–convened meetings of 10 US government leaders, played by individuals prominent in the fields of national security or epidemic response.

Drawing from actual events, Clade X identified important policy issues and preparedness challenges that could be solved with sufficient political will and attention. These issues were designed in a narrative to engage and educate the participants and the audience.

UK has plans to deal with pandemic causing up to 315,000 deaths

2013 paper outlines response to flu outbreak, long considered a more deadly risk than terrorism

Dan Sabbagh Defence and Security editor

March 6, 2020

Emergency planners have drawn up proposals to deal with “excess deaths” of between 210,000 and 315,000 over a 15-week period as part of longstanding measures to ensure the UK can cope with a deadly pandemic.

The “reasonable worst-case scenario” was first established a decade ago and still forms part of the underlying planning, supporting the coronavirus action plan announced by Boris Johnson at an emergency Cobra meeting on Monday.

Excess deaths at this level would amount to about 0.4% to 0.5% of the British population and are based in part on a 2.5% mortality rate, although this week Chris Whitty, England’s chief medical officer, said he anticipated a mortality rate of no higher than 1%.

Coronavirus news: Can you get coronavirus twice?

Person reinfected in Japan

CORONAVIRUS could remain dormant in those who have recovered, health officials have warned as a person in Japan has become reinfected by the disease.

By Sean Martin

UPDATED: 14:08, Thu, Feb 27, 2020

A tour bus operator who is in her 40s in Osaka has tested positive for the coronavirus strain for the second time, with 189 confirmed cases in Japan and at least three dead.

The woman was first diagnosed with coronavirus in late January and was discharged from hospital on February 1.

However, she has been reinfected leading to fears many of those who have recovered could be struck down once again.

Philip Tierno Jr, professor of microbiology and pathology at New York University, said: “Once you have the infection, it could remain dormant and with minimal symptoms.


Seasonality, explained: What warm weather could mean for the novel coronavirus

Wall Street Journal

March 04, 2020

President Trump has repeatedly suggested warm weather could slow the spread of the novel coronavirus. It appears he is referencing seasonality, which describes how active a virus is depending on the climate. In other words, the idea that people get sick more often in the winter.

Health experts say that for this strain of the coronavirus, which continues to spread across the globe, it’s too early to know if seasonality will have an impact. There are still too many unknowns to predict what will happen to the virus in warmer months.

Even if the novel coronavirus does dissipate in the currently impacted areas, it may find new life in the tropics and southern hemisphere. And that migration between hemispheres can actually prolong the lifespan of the disease. Experts say this means the virus could exist year round.
