Debunking the ‘Well played China’ conspiracy theory

Daily dose, Science, , ,

Along with the SARS-CoV-2 or coronavirus that has spread throughout the world causing a pandemic, conspiracy theories abound. One of the most recent ones being spread through social media can be summarized as follows:

China created the coronavirus to cause global economic collapse – people are told to stay at home to prevent the virus from spreading, businesses temporarily closed & work stoppage has been implemented.
This has sent stock prices dropping then China comes in to buy those low-priced stocks until we end up with a ‘world owned by China’.

Mind-blowing isn’t it? However this conspiracy theory is wrong on several points.

First, SARS-CoV-2 which causes COVID-19 is not a man-made or engineered virus. This has already been proven by scientific studies in the journal Nature Medicine and the New England Journal of Medicine.

Second, while it’s true that the US stock market has seen some decline as COVID-19 has spread in the US, the market has made a rebound after the federal government announced an economic stimulus package.

Third, Chinese investors did buy shares but the shares they bought are those of Chinese companies.

In addition, the Chinese government rolled out an economic stimulus package and spent more than 1.2 trillion yuan ($170 billion) buying shares to shore up prices.

Lastly, Peter Nolan, a professor of Chinese Development at Cambridge University, debunks the notion that China is ‘buying the world’ in his latest book entitled “Is China Buying the World?“

‘China has not bought the world and shows little sign of doing so in the near future,’ Nolan writes. ‘Their presence in high-income countries is negligible. This is a remarkable situation for a country that is the world’s largest exporter and its second largest economy and manufacturer. In other words, ‘we’ are inside ‘them’ but ‘they’ are not inside ‘us’.

Final words

Stop spreading conspiracy theories. Verify, look for sources or references that are credible. Since most of us are staying at home these days, use the time to search on Google and do some basic research.

If a message is forwarded to you and it has no references or citations, think twice before forwarding it to others or sharing it on social media. Verify. Google. Research. Or ask first from persons you trust to be experts or have knowledge about these things. Don’t be a sheep. Think! If there’s something more dangerous than the coronavirus is it ignorance and being too gullible.

And remember, stay at home. Stay healthy and be safe.

How long does SARS-CoV-2 survive in the environment?

Science, , ,

In a new report on the New England Journal of Medicine, investigators tested how long the SARS-CoV-2, the coronavirus that causes COVID-19, lasts in the air and on surfaces:

Viable in aerosols or mixed in air for 3 hours

Viable and detectable on the following surfaces:

Stainless steel and plastic – up to 72 hours

Cardboard – 24 hours

Copper – 4 hours

So frequent hand washing is still a very effective preventive measure as well as cleaning surfaces. Especially our mobile phones, tablets & keyboards.

Stay safe and as much as possible, stay indoors.

How hand washing with soap & water kills the SARS-CoV-2

Science, , , ,

The inevitable has happened, there are now 24 confirmed cases of COVID-19 in the Philippines and as I write this, the World Health Organization is on the brink of calling the outbreak a pandemic.

You may have doubts or misgivings about our own Department of Health, but they are still the best source of information about COVID-19 cases in the Philippines. Sharing unverified information via social media only helps to fuel panic and paranoia which could worsen the outbreak for all of us.

With the virus spreading locally, it’s important that we do our share to help contain or minimize its spread. You’ve often heard from medical professionals, government officials, your HR folk, the World Health Organization and media that one of the most effective ways to fight the spread of the SARS-CoV-2 is by frequent hand washing with soap and water. How so? It’s all rooted in the morphology or physical characteristics of the coronavirus. See the illustration below:

Coronavirus is a type of “enveloped” virus which means its core genetic material is surrounded by a membrane. That membrane, encircled in the image above, is called a lipid bilayer or two layers of phospholipids.

Lipid is a molecule that is like fat. Since soaps dissolve fat, washing your hands with soap and water for a sufficient amount of time, experts say singing “Happy birthday” twice does the trick, dissolves that lipid bilayer envelope of the coronavirus which in turn destroys the virus itself. This simple practice is very effective against germs, that’s why you often see surgeons spending a great deal of time thoroughly scrubbing their hands with soap and water before and after a surgery as shown in popular TV shows like Grey’s Anatomy or The Good Doctor.

So let’s do our part, frequently wash our hands with soap and water to keep it clean and fight off nasty germs like the coronavirus. Remember, before and after eating, wash your hands. After using the toiltet, wash your hands. Just got home from work or outside, wash your hands before touching anything else or your loved ones.

It cannot be overstated: wash your hands with soap and water.

New coronavirus in China similar to those found in bats – just like in the movie Contagion

Daily dose, , , ,

Have you seen the movie Contagion? Released in back in 2011, it showed how a deadly disease could easily spread throughout the world thanks to the convenience of air travel. How that deadly disease started was accurately shown in the film’s final scene:

Pathogens crossing from animals to humans has long been established by science. The recent outbreak of a pneumonia-like illness in China and the discovery that the virus closely resembles those found in bats just made the movie a lot more scarier. It just happened in real life, in our present times.

ScienceMag has details from a transcript of an interview with Xu Jianguo, head of an evaluation committee advising the Chinese government on what we know so far of this outbreak:

Q: The virus has been isolated from one patient, is that correct?

A: Correct. Two groups isolated the virus from samples from one patient. The viruses are nearly identical in morphology under electron microscopy. Researchers did laboratory investigations of 34 patients. A total of 15 were positive for the novel virus, [based on] sequencing samples of [fluid injected into the lung and collected for examination]. The teams got complete genome sequence data from about 10 patients. They are now attempting to isolate the virus from those samples as well. There are 19 cases with no evidence of the virus. There is no information available for the results of the remaining 25 cases.

Q: How close is this new virus to the SARS coronavirus?

A: The virus is similar to some of the published viruses collected from bats. But it is not close to SARS and not close to MERS.

Q: Is there any progress in tracing the original source of the virus?

A: I have no information. Personally, I’m interested, too. The virus looks like viruses isolated from bats, but how it was transmitted from bats to people is still a question. Several groups in China have been working on bat coronaviruses for years. I imagine they’re working on this but so far there is no information.

Q: Are other live animal markets being checked?

A: The Wuhan market has been closed. I have no information about other [markets]. Wild animals carry the risk of exposing people to new viruses. I think we should have more strict regulations and inspections of markets that sell wild animals, especially since the source of the new coronavirus has not been identified and eliminated.

One fatality has already been linked to the outbreak. Airports in Hong Kong, Singapore and the Philippines has imposed screenings of travelers from mainland China. Hopefully the disease is contained and there won’t be a repeat of the SARS or MERS epidemic a few years ago.
