GB0-371 information search - H3C Certified Senior Engineer for H3CRouting & Switching Updated: 2024

In the age of “Dr. Google,” it can be tempting to click your way to self-diagnosis — but an overload of health information can cause its own set of symptoms.

“Cyberchondria,” a subset of health anxiety, is described as a condition in which an individual excessively searches for health information online. 

While cyberchondria may not start as a physical disease, it can cause intense levels of anxiety and fear that can negatively impact a person’s health, according to Dr. Maggie Williams, a family physician in Scottsdale, Arizona, and medical director for MDLIVE Virtual Primary Care.

Dr. Marc Siegel, clinical professor of medicine at NYU Langone Medical Center and a Fox News medical contributor, said he and his colleagues used to call the condition “medical students’ disease.”

“When you know a little, but not enough, you imagine you have everything and constantly worry,” he told Fox News Digital.

Although cyberchondria is not listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a formal diagnosis, it’s thought to be closely related to hypochondria, a more general heightened anxiety about one’s health.

In 2014, two U.K. researchers, Eoin McElroy, and Mark Shevlin, created a “cyberchrondria severity scale” that measures a person’s score across eight areas: compulsion, distress, excessiveness, reassurance seeking, and mistrust of medical professionals.

Growing prevalence of cyberchondria

As Siegel pointed out, the condition is becoming more common over time.

“The invention of the internet and then the perfection of search engines created a global hypochondria, where patients searched to find possible explanations for their symptoms,” he said.

“It especially increased during the pandemic, when dogma abounded and everyone was suddenly an expert,” Siegel added.

A study published in JIMR Formative Research last year found that COVID-19 caused a spike in the condition in spring 2020, as people experienced higher levels of “cyberchondria-related distress and compulsion during the pandemic.”

One user shared experiences with cyberchondria on Reddit: “I thought that I might see something that will ease my mind, but … it makes it all worse and worse. Out of the 100 times I checked a symptom online, only 10 of them kinda made me feel safe.”

Another user wrote, “I’m pretty sure I have this. The pandemic definitely made my health anxiety worse. Unfortunately, the pandemic also made it harder to get in to see a doctor in a timely manner and so the internet is the next logical place to look for answers.”

In a small study by MDLIVE Virtual Primary Care, more than half of respondents said they searched online instead of going to the doctor, and more than two in five (42%) turned to social media to ask about their symptoms.

Another 22% said they rely on artificial intelligence for medical answers.

Nearly half of the 518 respondents, who provided data in August 2023, said they had misdiagnosed or mistreated an issue based on information they found online.

As Siegel warned, online medical information “isn’t often accurate, and it isn’t filtered, and it lacks clinical judgment.”

Telltale signs of cyberchondria

Several signs may indicate that people are experiencing cyberchondria, Williams said.

“Most people may not recognize the symptoms before it’s too late after they’ve invested hours, delayed access to the doctor, and worsened their overall anxiety,” she told Fox News Digital.

One warning sign is spending one to three hours or more at a time searching for symptoms online.

A quarter of the survey respondents said that when experiencing a health issue, they spend more than one hour searching for their symptoms online.

Obsessive medical searches may also get in the way of day-to-day activities, Williams noted.

In the MDLIVE study, 41% of respondents said that compulsively searching for symptoms has gotten in the way of their daily tasks.

“You may feel a compulsion to search online constantly, often rechecking symptoms multiple times, despite having completed an exhaustive search,” Williams said.

Another symptom of cyberchondria is high levels of distress and anxiety when searching for symptoms online — rather than easing concerns.

Fifty-eight percent of the participants in MDLIVE’s study said that searching online for their symptoms made them more anxious. 

“You may also have a heightened fixation on a particularly serious disease or condition, despite any evidence that you are suffering from it,” Williams added.

Addressing or preventing cyberchondria

If you think you may be experiencing symptoms of cyberchondria, Williams said it’s important to set boundaries on the time spent searching for health information online. 

“Resist the urge to check and recheck symptoms,” she advised.

She also recommends avoiding “deep diving” into online forums or threads where people share “worst-case scenarios.” 

“These tend to be exceptions rather than the rule, which can unnecessarily increase your anxiety,” she said.

It’s best to consult with a health care professional at the onset of any symptoms, Williams advised. 

“They can provide accurate information about your health concerns, potentially helping you to sidestep the slippery slope of cyberchondria,” she said.

Siegel noted that as a physician, one of his jobs is to help patients sort through their fears and worries and put them in perspective of real risk and disease. 

“This is even more the case with social media, where you end up searching through videos — especially TikTok — and become convinced you have a disease,” he said. “This all increases anxiety and is bad for health.”

For those who might have trouble physically getting to a doctor’s office, Williams suggested setting up a telehealth visit to address concerns in a timely manner, which will reduce the temptation to dive into online searching.

It’s important to address cyberchondria seriously, just as you would with any other health issue, she said.

“If you’re experiencing anxiety related to your health, you may find it helpful to speak with a mental health professional.”

While there are some reputable sources of health information on the internet, not all online information is factual or trustworthy.

“I still rely on the Centers for Disease Control and Prevention (CDC), National Institutes for Health, Mayo Clinic, NYU Langone, and CIDRAP (Center for Infectious Disease Research and Policy),” said Siegel.

That said, he warned that even vetted medical websites can still sometimes be wrong.

For those suffering from cyberchondria, Siegel advised them to find a doctor they can trust who can help guide them, while at the same time pulling back from online sources.

BEIJING, Dec. 1, 2023 /PRNewswire/ -- H3C, in collaboration with Spirent Communications, the industry leader in Ethernet test and measurement, completed the industry's first ever large-scale 800GE test with a high density of up to 64 800G ports. The test results demonstrate that H3C's 800G CPO silicon photonic switch series, H3C S9827, has excellent reliability and stability in key performance indicators such as overall switch capacity, full-port 100%-line speed forwarding, and transmission latency. This provides a powerful network core for accelerating the release of massive computing power and enhancing the application experience of computing power.

With AIGC driving a new wave of industrial intelligent transformation, AI large-scale models require data exchange among tens of thousands of servers and billions of parallel computations for massive data training. The growing demand for computing power puts forward stricter requirements for high-quality network connection technology. In the future, high-speed bandwidths such as 800G and 1.6T may become the main demand for large-scale training, and the performance of the switch is key to the overall network efficiency and response speed.

The test leveraged Spirent TestCenter 800G B2 Appliance. As the industry's first 800G test platform, the B2 provides strong L1-L2 feature set combined with broad L3 protocol support over multi-rate 800G/400G/200G/100G/50G speeds, and enables testing of network switches and routers for benchmark performance and scale standards required by today's AI/ML datacenter operators. 

The B2 supports multi-rate interconnection with the switches via cables, optical fibers and other methods, and supports performance testing based on benchmark performance and routing switch protocol standards. The test data shows that the H3C S9827 series, a new generation of 800G data center switches based on CPO silicon photonics technology, has a total switching capacity of up to 51.2T, and all 64 ports achieve 100%-line speed forwarding under different traffic. Each port transmission rate can reach 800Gbps. The product integrates CPO silicon photonics technology, fully meets the high throughput demand of intelligent computing network, and is suitable for AIGC cluster or data center high-performance core switching and other business scenarios, helping to unleash optimal computing power in the AIGC era.

The performance, stability, and latency of the network are crucial for intelligent applications, such as cloud computing and remote desktops, high-frequency financial transactions, remote medical scenes, etc., which have extremely high requirements for network latency. In actual operation, a 1% packet loss rate in Ethernet will lead to a 50% performance loss in the computing cluster, so how to design a low-latency, high-throughput networking solution and improve GPU computing efficiency is crucial. After testing, the single-port transmission average delay of H3C 800G CPO silicon photonic switch is 1.085 microseconds, 20% lower than the previous generation product, reaching the industry-leading level. The product uses CPO opto-electronic encapsulation technology to significantly shorten the high-frequency electrical signal interconnection distance from the switch chip to the optical module, helping to increase GPU computing efficiency by 25% within a single AIGC cluster.

"We were pleased to support H3C in verifying multiple breakthrough technology solutions for 800G Ethernet," said Andrew Liu, VP of Sales for Spirent in Greater China. "We have developed a comprehensive, end-to-end 800G testing suite that leverages decades of experience in Ethernet testing. This latest positive 800G test validating the reliability and high performance of H3C S9827, H3C's 800G CPO silicon photonic switch series, will help ensure successful deployments of this complex new technology and reliable high-speed networks to meet future demand."

Yutao Li, Vice President of Network Product Line of H3C and General Manager of Switch Product Line, said that "The 800G high-performance switch, bolstered by CPO technology, will provide higher network capacity for cutting-edge applications such as AIGC and large-scale model training, paving the way for further improvement in the scale and computing power of computing clusters. This joint test fully reflects H3C's leading technical strength in the field of digital infrastructure. In the future, H3C will also help customers from various industries to comprehensively boost Ethernet performance, fully unleashing the value of computing power."
