Study finds COVID-19 coronavirus can survive 28 days on some surfaces

It’s extremely robust on banknotes, glass, steel, plastic and mobile phones


These results highlight the need to wash hands as well as touchscreens regularly



The coronavirus that causes COVID-19 can survive on items such as banknotes and phones for up to 28 days in cool, dark conditions, according to a study by Australia's national science agency. Researchers at CSIRO's disease preparedness centre tested the longevity of SARS-CoV-2 in the dark at three temperatures, showing survival rates decreased as conditions became hotter, the agency said Monday.

The scientists found that at 68 degrees Fahrenheit, SARS-CoV-2 was "extremely robust" on smooth surfaces — like cell phone and other touch screens — surviving for 28 days on glass, steel and plastic banknotes.

At 86 degrees Fahrenheit, the survival rate dropped to seven days and plunged to just 24 hours at 104 degrees Fahrenheit.

The virus survived for shorter periods on porous surfaces such as cotton — up to 14 days at the lowest temperatures and less than 16 hours at the highest — the researchers said.

This was "significantly longer" than previous studies which found the disease could survive for up to four days on non-porous surfaces, according to the paper published in the peer-reviewed Virology Journal.

Trevor Drew, director of the Australian Centre for Disease Preparedness, said the study involved drying samples of the virus on different materials before testing them, using an "extremely sensitive" method that found traces of live virus able to infect cell cultures.

"This doesn't mean to say that that amount of virus would be capable of infecting someone," he told public broadcaster ABC.

He added that if a person was "careless with these materials and touched them and then licked your hands or touched your eyes or your nose, you might well get infected upwards of two weeks after they had been contaminated."

Critical for "risk mitigation"


Drew said there were several caveats including that the study was conducted with fixed levels of virus that likely represented the peak of a typical infection, and there was an absence of exposure to ultraviolet light, which can rapidly degrade the virus.

Humidity was kept steady at 50 percent, the study said, as increases in humidity have also been found as detrimental to the virus.

According to the CSIRO, the virus appears to primarily spread through the air but more research was needed to provide further insights into the transmission of the virus via surfaces.

"While the precise role of surface transmission, the degree of surface contact and the amount of virus required for infection is yet to be determined, establishing how long this virus remains viable on surfaces is critical for developing risk mitigation strategies in high contact areas," CSIRO's Debbie Eagles said.

The main message remains that "infectious people are far, far more infectious than surfaces", Drew told the ABC.

"But nevertheless, it may help to explain why even when we got rid of the infectious people, we do occasionally get these breakouts again, sometimes even in a country which is considered to be free," he said.

China's Covid-19 vaccine will be available for all, could be ready for public use early next year

China will make its Covid-19 vaccine a global public good when it is ready for application after successful research and clinical trials, a senior Chinese official said.

.


Wang Zhigang, minister of science and technology, said at a press conference in Beijing yesterday that international cooperation should be strengthened in vaccine development, clinical trials and application.

Vaccine development should focus on ensuring safety, effectiveness and accessibility, he added.


To date, four inactivated vaccines and one adenovirus vaccine had been approved for clinical trials, said a white paper titled “Fighting Covid-19: China in Action”, which was released by the State Council Information Office yesterday.

While scientists in China and abroad had kept up with mutual developments, China led the world in the development of certain types of vaccines, the white paper said.

A great deal of international cooperation had been carried out so far in terms of vaccine development, according to Wang.

Highlighting the significant role that vaccines had played in human history, Wang said both Chinese scientists and those in other countries were trying to make contributions to building a global community of health for all.

He, however, noted that the development of vaccines is a rigorous and complex procedure, which faces many uncertainties and may take a long period of time.

Wang also said drug research and development had been a priority in the efforts of fighting the pandemic in China since the very start, with more than 160 research institutes and enterprises taking part in various programmes.

Meanwhile, Ma Xiaowei, minister of the National Health Commission, said at the press conference that China would strengthen the building of public health emergency response system as the Covid-19 pandemic had exposed flaws in the country’s medical and public health system.

The country would improve the investment mechanism on public health system so that it would be in a better situation to handle disease prevention and control, he said.

Different levels of disease prevention and control centres would have a clearer definition of their functions, with the Chinese Centre for Disease Control and Prevention making the final decision on scientific research, testing, guidance and pathogenic analysis on epidemic diseases, Ma added.

“Moreover, we will further improve the reporting and warning system of major public health incidents by building public opinion monitoring system, reporting system by medical workers and reporting system on scientific findings,” he said.

There would also be new policies in cultivating more talents in public health and improving their treatment, especially talents in pathogenic detection, epidemiological investigation, laboratory testing and analysis on epidemic situation, he added.

China could have Covid-19 vaccine ‘ready for public use early next year’

  China may have a vaccine against the  deadly Covid-19 for emergency use by September and for the general public early next year, a top Chinese public health expert has said..

This is the first time a Chinese official has put an estimate on the timescale for development of a coronavirus vaccine, believed to be the key to containing the global pandemic. The US Food and Drug Administration believes a vaccine in the United States could be at least a year away, and the World Health Organisation (WHO) has said that it could take 12 to 18 months..

Gao Fu, head of the Chinese Centre for Disease Control and Prevention, on Thursday told China Global Television Network, the overseas arm of the state broadcaster, that vaccines currently at phase two or three of clinical trials could be available by the time of a potential second wave of outbreaks. Three Chinese vaccines have completed the first phase of trials.

“We are in the frontline for the vaccine development, and we may have a vaccine ready for emergency use by September,” Gao said. “These newly developed vaccines, which are still under phase two or phase three clinical trials, could be used for some special groups of people, for example health care workers.”.

Gao added that “we may have a vaccine for the healthy population early next year”, but stressed that its feasibility would depend on “progress of our development”..

Unlike influenza – whose frequent mutations must be anticipated by vaccine makers preparing for seasonal outbreaks – Sars-Cov-2, the virus that causes the disease Covid-19, is believed not to mutate as often and is unlikely to become a “new norm” such as seasonal flu, according to virologist Shi Yi, of the Institute of Microbiology, Chinese Academy of Sciences..

“Some experts believe the epidemical new coronavirus will become a norm and spread like the influenza virus... but [we believe] such probability would be relatively low,” Shi told reporters at a regular briefing in Beijing on Thursday. “At present, there is no evidence that the new coronavirus has the same variability as influenza virus.”.

https://youtu.be/8oQM48rToSc

Shi also rejected the possibility of Covid-19 becoming a chronic illness, given that the virus multiplies mainly in patients’ respiratory tracts and no continuous virus carrying has been observed. He added that the same was true of the century’s two other known coronavirus-induced diseases, severe acute respiratory syndrome (Sars) and Middle East respiratory syndrome (Mers)..

As the coronavirus has swept the globe and infected more than 2.7 million people, causing nearly 200,000 deaths, scientists have raced to develop a vaccine to combat the pandemic. By Thursday, six candidates had entered into clinical trials and 77 others were in preclinical studies, according to the WHO..

Newly added to the group being trialled was a viral vector vaccine developed by a team of researchers from the University of Oxford, which was injected into its first two volunteers on Thursday and was based on a technology used to develop a vaccine for Mers..

The team’s leader, Dr Sarah Gilbert, reportedly expressed hope that 1 million doses would be ready for use by September.

Trump adviser claims China may be keeping data to win virus vaccine race


US biotech start-up Moderna started the world’s first coronavirus clinical trial in March, on its mRNA vaccine. Another US company, Inovio Pharmaceuticals, kicked off its first human trial of a DNA vaccine last month..

Three vaccines developed by Chinese companies and researchers have passed their first phase of trials for safety and earlier this month started the second phase, involving hundreds to more than 1,000 volunteers testing their effectiveness and researchers assessing vaccination doses..

https://youtu.be/UEzZ6sZegso

The trio included the Adenovirus-vector vaccine, by Tianjin-based Cansino Biological I and Beijing Institute of Biotechnology, and two inactivated vaccines developed by the Wuhan Institute of Biological Products and Sinovac Research & Development in Beijing..

China has experienced an easing of the Covid-19 epidemic after nearly five months of the outbreak, which was first reported in the central city of Wuhan. It reported only four locally transmitted and two imported cases on Thursday, while the number of patients still under treatment has fallen to below 1,700..

Existing drugs ‘may prove effective on coronavirus before vaccine comes’

But vaccines under development will require an effective patient population for the third phase of trials, to allow their effectiveness to be tested in an environment where the virus is still prevalent..

Researchers must overcome difficulties such as “vaccine enhancement”, in which a disease is exacerbated in a vaccinated person infected with the actual virus..

Left vs right: intensified social confrontation in the US


Conflicts between the left-wing and right-wing activists in the US have intensified in recent years. Expert warned that the two ideologies could undoubtedly intensify social confrontation amid pandemic, riots the 2020 US presidential election.

Washington Post published an article on Wednesday titled "CIA veterans who monitored crackdowns abroad see troubling parallels in Trump's handling of protests", in which current and former US intelligence officials pointed out the similarity between the events in the US and the signs of decline or democratic regression they were trained to detect in other nations. Likewise, former CIA officer Marc Polymeropoulos tweeted on Tuesday that "It reminded me of what I reported on for years in the third world."

In many cases, the so-called democratic regression in other nations and the third world was caused by the US intervention. Again, the US has shot itself in the foot.

The spreading unrest in the US shows that the US political system is not immune to social instability. Many people are using the hashtag #AmericanSpring on Twitter, comparing the social movement Arab Spring with the violent protests triggered by the death of George Floyd.

Some have also raised the question: Is a color revolution taking place in the US?

The US government manipulated color revolutions in some Central Asian and Eastern European countries from the 1980s. It has also tried to provoke color revolutions in many more places, including China's Hong Kong Special Administrative Region. Washington has created instability in and around many countries it considers geopolitical opponents.

Under the disguise of protecting democracy, liberty and human rights, the US government aims at subverting opponents and shaping international environment in favor of US strategic interests. The subversion plots, often carried out by CIA, left many countries struggling in a chaotic situation for a long period of time.

And now, the US' wanton destruction of social order in other countries has backfired and put itself in a moral dilemma.

Facing unabated protests, American political elites are now debating how to put the spreading chaos to an end, whether the police should get tough and whether troops should be deployed to stabilize the situation.

The importance of maintaining order and stability is laid bare as Washington is struggling to deal with the angry masses. The chaos in the US shows that simply shouting slogans of democracy and freedom will never work.

By trying to manipulate other countries' affairs, Washington is harming others as well as itself. As the US still provokes instability worldwide, other countries need to insist that the US should not meddle in their internal affairs.

China has decided to donate additional $30 million in cash to WHO to support its global fight against , in particular strengthening developing countries' health systems. China already donated $20 million in cash to WHO on March 11.


He added that China’s contribution to the UN agency “reflects the support and trust of the Chinese government and people for the WHO”.

China to donate another 30 mln USD supporting WHO's fight against COVID-19 


China decided to donate another 30 million U.S. dollars to the World Health Organization (WHO) in support of global efforts to fight COVID-19 and the construction of public health systems in developing countries, a Foreign Ministry spokesperson said here Thursday.

Spokesperson Geng Shuang told a news briefing that the WHO, led by Director-General Tedros Adhanom Ghebreyesus, had actively fulfilled its duties with objective, science-based and fair position and played an important role in assisting countries in responding to the outbreak and boosting international cooperation on COVID-19.

Geng said to support the WHO is to defend the principles of multilateralism and safeguard the status and authority of the United Nations at a crucial time of the battle against the pandemic, adding that the virus is the common enemy of humankind, and the international community can only defeat it through unity and cooperation.

In March, China donated 20 million dollars to the WHO to support the global fight against COVID-19.

The spokesperson said China's donations to the WHO reflected the support and trust of the Chinese government and people in the organization, and China also made its own contributions to global public health and the fight against the pandemic.

"China will continue to stand in solidarity and render mutual assistance with other countries to jointly overcome the pandemic, safeguard regional and global public health and build a community with a shared future for mankind," he said.
