A viral trend labeled as the “mystery virus” is gaining momentum on TikTok, where numerous users report a range of symptoms like congestion, dizziness, and breathlessness. Yet, health specialists assure that this illness likely mirrors common respiratory ailments and doesn’t pose significant threats. Managing symptoms involves using over-the-counter remedies, getting ample rest, and staying hydrated. Emphasizing good hand hygiene is recommended to curb the spread of viral infections.

As the cold and flu season persists, chatter surrounding a purported “mystery virus” intensifies online. Speculations ignited in February after a viral video posted by TikTok user @thatgirlkanesha sparked curiosity.

The video captured her incredulity: “Everyone’s falling ill to some unknown virus, yet they can’t pinpoint its name?” She recounted her own recent experience with these symptoms, which left her feeling dizzy, nauseous, and on the verge of fainting, prompting questions about the coherence of these reported symptoms.

Subsequent videos flooded the platform, with creators alleging symptoms reminiscent of COVID-19, despite testing negative. Nevertheless, medical experts reassure the public that this purported “mystery virus” is unlikely to pose a significant threat.

What is the “mystery virus” everyone is talking about on TikTok?

While the precise illnesses depicted in the trending online videos remain unclear, health experts suggest there’s little mystery to unravel.

The symptoms described, including coughing, fever, fatigue, and muscle pain, are typical of various viral infections, such as colds, COVID-19, and influenza,” explains board-certified family physician Dr. Sarah Bonza.

Moreover, respiratory syncytial virus (RSV) is circulating and can manifest similar symptoms to other viral infections like colds, flu, or COVID-19.

“These diseases often share overlapping symptoms, leading to potential misidentification even without formal testing,” Dr. Bonza emphasizes.

General practitioner and Say GP founder, Dr. Semiya Aziz, highlights the possibility of common viral illnesses mutating over time, producing new strains.

“This doesn’t imply a new virus; it’s merely an evolution of the existing virus,” she clarifies. “Such changes may introduce new, previously unrecognized symptoms, possibly explaining the ‘mystery virus’ individuals are reporting.”

The dangers of misinformation on social media platforms like TikTok

Feeling apprehensive about experiencing unfamiliar symptoms is natural, but both experts concur that the “mystery virus” currently circulating on TikTok is likely a common respiratory illness.

Dr. Bonza notes that such trends can trigger undue health anxiety. “We’re in a post-pandemic era, and when combined with social media, health concerns can spread rapidly, even without substantial evidence,” she observes.

Moreover, Dr. Bonza emphasizes that the symptoms reported are nonspecific and akin to those of the flu, suggesting they could stem from common viral infections.

Considering the season, Dr. Bonza finds this unsurprising. The unknown often stirs concern, yet TikTok’s “mystery virus” is unlikely to be grave.

“As alarming as these new symptoms may seem, individuals affected haven’t deemed them life-threatening or requiring hospitalization,” Dr. Aziz notes. “While some symptoms may induce fear, most viral infections resolve within days, with or without over-the-counter treatment.”

Online assertions can instill unnecessary panic, and Dr. Bonza advises caution in trusting purported health information online. Waiting for official announcements from reputable sources like the CDC or local health authorities is prudent.

“There’s a meticulous protocol public authorities follow for swiftly managing infectious diseases, and in the absence of an official announcement, there’s no need for alarm,” Dr. Bonza reassures.

How to treat symptoms like those associated with TikTok’s “mystery virus”

Although the mystery virus likely isn’t a cause for alarm, coping with its symptoms can be unpleasant and debilitating. So, how can you manage them?

“Rest is paramount,” advises Dr. Aziz. “It allows the body to combat the virus effectively, so prioritize ample sleep and avoid overexertion.”

Staying hydrated by consuming plenty of fluids is also essential.

“This not only aids hydration but also thins mucus secretions, easing symptoms like sore throat and dry cough,” Dr. Aziz explains.

Since antibiotics are ineffective against viruses like colds and flu, opting for pain relief medication is advisable. Dr. Aziz suggests over-the-counter pain relievers to alleviate fever, headaches, and body aches.

However, Dr. Bonza advises seeking medical attention if the fever persists beyond a week or if respiratory distress symptoms emerge, such as difficulty breathing, shortness of breath, grunting, sweating, or wheezing.

How to protect yourself against respiratory illnesses

Bonza emphasizes the importance of practicing hand hygiene with soap and water to curb the spread of germs, serving as an excellent starting point.

She further suggests boosting your vitamin C intake and prioritizing rest to bolster your immune system’s resilience.

In addition, maintaining healthy lifestyle habits plays a crucial role.

Eating a balanced diet, staying physically active, getting sufficient sleep, managing stress, and avoiding tobacco smoke and excessive alcohol consumption can all contribute to supporting your immune system,” notes Aziz.

Incorporating these preventive measures into your daily routine can diminish the risk of viral infections and safeguard both yourself and others from illness, Aziz underscores.

Staying current with vaccinations, including annual flu shots and COVID-19 vaccines, is also advisable. These vaccinations lower the likelihood of contracting viral illnesses and mitigate the severity of infections if they occur.


Health professionals assert that the purported “mystery virus” gaining traction on social media platforms such as TikTok isn’t shrouded in much mystery.

The symptoms outlined in numerous online discussions align with those commonly associated with respiratory illnesses prevalent during the cold and flu season.

While health-related content circulating on social media has the potential to evoke anxiety, the so-called “mystery virus” is improbable to warrant significant alarm.
