MIT Researchers Develop AI Model that Accurately Identifies Asymptomatic COVID-19 Carriers

The COVID-19 Pandemic doesn’t seem to be going away anytime soon. The virus continues to spread drastically and have a devastating effect in areas where outbreaks have occurred. However, since the early days of the pandemic, there have been reports of asymptomatic carriers; these carriers are able to spread the virus without showing any outwardly recognisable signs of infection. This also makes them one of the largest unsolved problems of the current COVID-19 pandemic. This group of individuals are less likely to seek testing and, in turn, be diagnosed and treated.

However, that’s about to change. A group of researchers at the Massachusetts Institute of Technology (MIT) have developed an AI model that has been able to accurately identify asymptomatic carriers based on the way they cough. The AI model has been able to accurately discern and identify 98.5% of coughs from confirmed COVID-19 patients and 100% of asymptomatic carriers.

Using A.I. to Identify Unique Markers in Coughs

The team at MIT, consisting of Jodi Laguarta, Ferran Hueto, and Brian Subirana, developed the mode on a neural network called ResNet50. ResNet50 is a type of neural network that is able to discern and identify differences and similarities in data. Until now, ResNet50 was used primarily in visual discernment. However, the team at MIT has applied it in identifying markers when people cough.

Their model was initially developed to help detect early signs of Alzheimer’s which can present in the way people cough. This include the person’s emotional state, changes in lung and respiratory performance and vocal chord strength. These are known markers for someone who could be experiencing early onset Alzheimer’s.

Using the three criteria, three independent machine learning algorithms were train and then layered on each other. The team also included an algorithm for muscular degeneration on top of the model. In tandem, these machine learning layers made it possible for the team to detect and identify samples from Alzheimer’s patients.

Detecting the Indiscernible

In April, the team looked into applying the AI model to help identify COVID-19 patients. To do this, they established a website where people could record a series of coughs with their mobile phone or any other web enabled device. In addition to their submissions, participants had to fill up a survey of their symptoms, COVID-19 status, and if their method of diagnosis. Other factors such as their native language, geographical location and gender were also collected. They have, to date, collected over 70,000 recordings which amounts to about 200,000 forced cough samples. This is the largest known cough dataset that has been collected so far according to Brian Subirana.

The model proves a long known fact that COVID-19 does in fact affect respiratory function. However, it also draws similarities between the presentation of temporary respiratory degeneration to the neurodegeneration present in Alzheimer’s patients. That said, it also shows that there are sub-clinical presentations of the disease in asymptomatic individuals. The AI algorithm is able to detect and identify individuals with these presentations, providing a much needed boost to potential diagnoses of these individuals.

More significantly, the team has developed a method in which pre-screening can be done to help curb the spread of COVID-19. What’s more, their research could be the foundation of future diagnosis when it comes to sub-clinical presentations of diseases. That said, Brian Subirana highlights that the strengths of the tool lies in its ability to differentiate coughs from asymptomatic carriers from healthy individuals. He also stresses that it is not meant to be used as a definitive test for COVID-19.

techENT Interviews Nicole Tan of Facebook

This whole COVID-19 situation has been quite trying for plenty of people. For Malaysia, the country is in its third phase of a state sanctioned quarantine, or Movement Control Order (MCO) in their words. The MCO means that there are some imposed restrictions to how you can move about in the region. No one can come into or out of Malaysia at this time too. In other words, we are under a limited lock down.

This also means that most organisations in Malaysia are on a work-from-home policy, including us. Working from home is not a new concept though. Funnily enough, it is not tech-based firms that has gone big with work-from-home concepts. Still, this is the time when everyone just must start adopting the work-from-home culture. Not like they have a choice anyway in Malaysia.

Facebook has been one organisation at the forefront of business transformations in the region. They have also transformed how businesses work and sell their products in the modern world. They are more than just a Social Media app you have on your smartphones. Facebook is more than an app just to keep in touch with your friends.

It has become a live news channel, where you can view live updates on the most current news. You can set up watch parties (limited to Facebook Watch and videos) to a live event. It has become a live event space, if you might for the public. With Messenger and WhatsApp, it is a communication powerhouse; an all-in-one tool for your daily communication needs.

If you need to, Facebook can be your marketplace, or the place where you shop with marketplace. With Facebook Watch, it is your source of entertainment. It can even be your calendar if you really need it to be. It is truly a one-stop, go-to, solve-it-all platform where you can find anything and everything.

That is also why when we were given the chance to sit down with Nicole Tan of Facebook Malaysia, we took the offer up.

Nicole Tan is not just a random person in Facebook Malaysia. She is the Facebook Malaysia’s Country Director. When you say top brass, she is it for Facebook Malaysia. The buck stops with her. Of course, no one is better qualified to talk about Facebook’s presence and efforts in Malaysia than her.

We started the interview with a burning question of ‘how?’ Everyone is in this trying period that is the MCO and plenty are forced to bring work home. In that case, everyone has to adapt to a completely new working environment and culture. Every other person is of course looking toward the big tech names for guidance and inspiration.

Facebook has always had a very flexible approach toward this issue of course. Being a tech firm there are already measures in place for a work-from-home situation. In fact, Facebook Malaysia has adopted the work-from-home policy even before Malaysia’s MCO is implemented. According to Nicole Tan, the firm has adopted to the situation very quickly. Naturally, there has been a lot more web-conferencing that is needed for daily operations. For Nicole then, it is almost just like any other day in the office; just with more video conferencing than ever.

There is one big concern for consumers who are on Facebook though. The platform has become one of the biggest news channels in the world. In Malaysia at least, plenty rely on Facebook for the latest updates in the region. In these trying times, more so rely on Facebook and its services for information. With fears of cyber attacks and scams related to COVID-19 as well, fake news is another big concern. In that, Facebook has been working very closely with their partners which include health institutes and certain government departments to verify news sources. They are not just doing it on Facebook as a platform though. They are also doing it on Whatsapp, Messenger and even Instagram.

All this accumulates to Facebook’s very own COVID-19 specific information center. The section is also an accumulation for your benefit. Facebook, through the center is working to bring forward tips and resources from experts and other certified sources to keep you healthy and informed at this time. This is not something new for Facebook. At this time though, to verify all the news, they have spent quite a significant amount of money to work with fact-check networks just so that you get the correct information.

That is not all they have been doing in the fight for COVID-19 though. Being one of the largest tech firms in the world, they could contribute plenty to the efforts around the world. They join other multinationals in donating relief funds and even development of vaccines. In total, they probably has put forth about US$ 70 million in the efforts of not just fighting the disease, but also fighting the side-effects of the global pandemic.

In that also, Facebook is using their platform to help Small Medium Enterprises (SME) even here in Malaysia. Globally Facebook will be offering grants for SMEs or even guide businesses to survive this period of MCO. If you need more information on that, do visit their website.

Nicole also added that they are also working with certain Non-Government Organisations (NGO) and Non-Profit Organisations; one of them is Yellow House KL. Of course, there are more that they are doing in the global fight of COVID-19. You can keep yourselves updated on their efforts on their newsroom.

Nicole also gave us a lot of good insights on how Facebook has adapted to the global pandemic situation. For that you should refer to the interview video. Facebook is a free Social Media platform that is available for free on Google’s Play Store for Android and Apple’s Play Store for the iOS.

COVID-19 isn’t Just a Biological Pandemic, It’s A Cyber Security Pandemic

The COVID-19 pandemic is one of the most unprecedented events to have occurred in the past decade. In fact, the last time a major pandemic hit was in the 1910s. Since then, there have been milder pandemics which have occurred more recently in 2009 (Influenza A H1N1). The world has changed drastically since these pandemics. That said, the fact that the world is so interconnected and digitally dependent, makes the COVID-19 pandemic even more unique.

It wouldn’t be too far-fetched to say that with the COVID-19 pandemic, we’ve learnt that pandemics aren’t just about being biologically compromised anymore. In fact, Flavo Aggio, the Chief Information Security Officer at the World Health Organisation (WHO) attributes more than 15,000 deaths worldwide in this pandemic alone to the cyber attacks that healthcare agencies such as WHO face on daily basis. What’s more apparent is the number of cyber attacks related to COVID-19 have increased substantially since the pandemic began. Great Horn, a cloud-based security platform, reports that currently about 2% of email traffic related to COVID-19 comes from malicious players looking to get access to pertinent, personal information. Other security companies have reported that the number of cyber attacks linked to the COVID-19 pandemic have more than doubled since its emergence.

Proof is in the Pudding – Increased Cyber Attacks are putting Patients& People at risk

In the most recent attack against the WHO, a malicious hacker group known as DarkHotel setup a site to mimic WHO’s internal email page in an effort to get login information of WHO employees to access sensitive information. The group’s activities were first detected by Alexander Urbleis, a cyber security expert and attorney at Blackstone Law Group in New York. Urbelis mentions that he detected the site’s activation on 13 March.

This attack comes from the group after it vowed not to attack healthcare agencies and research centers during the pandemic. That said, the WHO was able to fend off the attack without getting compromised.

However, this hasn’t been the only COVID-19 based attack. During the same time, Brno University Hospital was forced to shutdown their technological services. This was due to a breach in cybersecurity which forced the hospital to take preventative measures. The attack compromised the health of all of the patients who required advanced testing. It forced doctors and nurses to chart manually which caused delays in care.

Perhaps more alarming is how hacker groups have also been targeting research centers and pharmaceuticals. Hammersmith Medicines Research (HMR), one of the companies involved in developing a vaccine for SARS-CoV-2, the virus causing COVID-19, reported that it was part of a ransomware attack. This attack compromised the information of about 2,300 patients involved in trials. The group behind the attack demanded money after gaining access to the files. These patient files have since found their way to the dark web, making them vulnerable to further compromise.

It’s becoming increasingly obvious that while malefactors are targeting healthcare institutions and companies, the ones who truly pay the price are the patients. With their data at risk and treatments being delayed or interrupted, we are seeing a larger, more worrying pool of victims.

Compromised Cyber Security Could have Lasting Effects

That is only the tip of the iceberg. With pertinent patient information in the wild, these patients have been exposed to a larger cyber threat; one that could be even more devastating to them after the pandemic. Information such as their addresses, social security and passport details are now available online – if you know where to find it. Another question remains: “Were these patients informed of such a data breach?”.

With the compromised information, malicious players will be able to gain access to a number of things including bank accounts and other important accounts. In fact, hackers will able to social engineer this information to gain access to emails, social media and more by simply connecting the dots. The fact of the matter is, most passwords and logins are linked to a person’s social history or items like their social security numbers.

These breaches have potential psychological and physical repercussions that not many are aware of. Being the subject of a data breach or having an email or bank account compromised as a result will result in lost time and psychological stress. Keep in mind, that some of these attacks hold your vital information ransom and demand for money. This would definitely lead to increased anxiety.

Personal Hygiene Must Include Your Digital Footprint

It can’t be any more obvious that we are in an age where our digital lives are increasing intertwined with our daily lives. Even in an epidemic, we are seeing the effects of cyber attacks on our daily lives Hence, with attacks on the rise, users like you and me must also take precautions to protect our digital footprint. It is as essential as washing our hands and avoiding touching our face in this pandemic.

We can start with one simple step – pay attention to the details. Kaspersky has reported that there has been an uptick in look-a-like domains since the onset of the COVID-19. In particular, when it comes to authoritative domains. In particular, they’ve highlighted an email supposedly from the CDC (Center for Disease Control) in America. The official domain for the CDC is cdc.gov; however, emails have been sent from an email from cdc-gov.org. The small difference when it comes to this domain could be the difference between getting compromised or getting official information.

The next step you can take is, like washing hands, spend a little time refreshing your passwords. Good password hygiene is essential to keeping your information secured. Look at changing your passwords on a bi-monthly, if not monthly basis. If you’re working in an industry that requires heightened security and privacy, you know that they have policies that require you to change your password every 3 months, at the very least. So, why are you worth any less?

One of the most basic things you can do for increased security is to activate two factor authentication (2FA). When you activate 2FA, you will be prompted to give an additional item for authentication. This will help verify your identity. That said, activating 2FA is no excuse not to change your password on a regular basis.

With these steps as a starting point, you’ll have better security on the internet. That said, it’s just a start. Don’t get too comfortable with yourself when it comes to internet security. With more and more attacks focused on taking advantage of lapses of judgement, we need to be more alert. Even when we’re searching for information, it’s important we pay attention to the details, check website addresses and keep vigilant on the links in your email. While things may seem bleak, it’s no excuse to stay away from the internet. Just be more alert and vigilant and enjoy one of the best inventions since sliced bread.

Sprinting to Bring Tech to Emergency Hospitals in Wuhan, China

This article is contributed by Varinderjit Singh, General Manager, Lenovo Malaysia.

In a staggering feat of modern construction, crews in Wuhan, China built two emergency hospitals in 10 days shortly after the coronavirus outbreak began to relieve an overburdened hospital system for this unprecedented pandemic. For a small group of Lenovo employees, those days in late January will be forever remembered as a time of rapid and meaningful collaboration alongside colleagues and friends to meet a devastating technical challenge.

Emergency Construction Begins

As hospitals in Wuhan became instantly overcrowded with patients, construction began on January 23 of the Huoshenshan hospital and again on January 27 of the Leishenshan hospital. The day after emergency construction crews broke ground on the first hospital, Lenovo created an epidemic prevention and control team that decided to donate all the IT equipment needed by Huoshenshan.

Delivering hundreds of computers, tablets, printers, and more to the hospital in such a short time—and in a way that would be safe for everyone involved—posed an incredible challenge to the team. Still, the scale and operational experience of Lenovo made the team optimistic they could contribute all the necessary parts within the aggressive 10-day timeline.“We just want to do something, to help by providing whatever IT equipment the hospital needed,” said Lu Yuan, General Manager of Lenovo’s Commercial Customer Business of Hunan and Hubei provinces (Wuhan is located in Hubei province).

Round the Clock Coordination

Getting the products to the hospitals through a largely quarantined city was the first task, followed immediately by assembling IT and maintenance volunteers needed to make it all work on site. Lenovo’s after-sales service engineers from across the country, Xu Tan, Senior Manager of Lenovo Customers of Hubei and Wu Zhiyuan, Senior Sale Manager of Commercial Solutions volunteered and worked non stop to better equip the front-line medical staff for a better fight.

“The complex environment is far beyond imagination,” said Wu. “Under normal circumstances, with the speed of Lenovo, 15 people and 500 sets of equipment can be fully installed and commissioned in less than 24 hours. However, the 24-hour, non-stop construction requires coordination from multiple parts, such as communicating with the hospital’s organizer, establishing the on-site network, and syncing with tech experts at Lenovo headquarters.”

Wu continued, “In general circumstances, one PC is equipped with one printer, but for the hospital each medical PC needs to connect to three printers: a wristband printer, a case printer, and a receipt printer, which is a tough challenge for compatibility. Huoshenshan alone has 500 desktops, and if we install the equipment one by one, the workload is beyond imagination. But with the help of Lenovo IDV [a desktop solution that can quickly install thousands of PCs] we installed the desktops of 500 computer terminals at once, enabling doctors and staff to use them immediately. Also any problems can be handled remotely, which is not only extremely efficient but also reduces the frequency of entering any contaminated areas.”

A group of Lenovo engineers and hospital support completed the installation and commissioning of more than 1,400 pieces of equipment at both hospitals in only a few days to ensure that the hospitals would be able to provide services to patients on time.

By February 2, all IT equipment donated to Huoshenshan Hospital was delivered, updated, installed, and put into use—just one day before its doors opened to patients on February 3.

This was the beginning of Lenovo’s efforts to support employees, customers, and communities as COVID-19 spread. In China, Lenovo’s efforts continue, bolstered by the friends from Lenovo all around the world.
