Doctors Dismiss False Claims of Emerging ‘COVID-25’ Strain

Recent rumors regarding a new strain of the virus causing COVID-19, dubbed “COVID-25,” have been circulating since fall 2025. Claims suggest that this new variant exhibits unique symptoms, prompting widespread concern among social media users.

Debunking the ‘COVID-25’ Claims

Despite the panic, medical experts confirm that there is no verified strain called “COVID-25.” Instead, two notable variants of the SARS-COV-2 virus are being observed, both falling under the Omicron subvariants.

Influential Social Media Claims

The misinformation originated from a TikTok video by an individual identifying himself as “Dr. Tony.” This video amassed over 3.1 million views and presented a list of supposed new symptoms. Some of these symptoms included:

• Extreme fatigue resembling a lack of sleep
• Sore throat and persistent dry cough
• Mild fever fluctuating between 100-101°F (37.8-38°C)
• Intense headaches similar to migraines
• Loss of appetite and occasional stomach pain

Though engaging, these claims do not align with current medical understanding. Trusted health organizations, including the Centers for Disease Control and Prevention (CDC), detail common symptoms of existing COVID-19 strains that encompass some of the items from the viral video.

Current COVID-19 Strains in 2025

Experts have identified two new SARS-COV-2 variants circulating: the “Nimbus” strain (NB.1.8.1) and the “Stratus” strain (XFG). Each possesses distinctive features and symptoms.

1. Nimbus Strain (NB.1.8.1)

This variant is noted for its characteristic “razor blade throat,” with common symptoms including:

• Severe sore throat, particularly painful when swallowing
• Persistent fatigue
• Mild cough
• Nasal congestion or runny nose
• Fever and muscle aches
• Sneezing
• Less common digestive symptoms, such as nausea or diarrhea

2. Stratus Strain (XFG)

The Stratus strain has gained prominence due to its ability to evade the immune response. Symptoms associated with Stratus include:

• Persistent dry cough
• Tiredness or fatigue
• Fever
• Shortness of breath and chest tightness
• Loss of taste and smell
• Brain fog

Conclusion

The claims about “COVID-25” are unfounded and stem from misinterpretation of symptoms associated with circulating variants. Public health officials emphasize the importance of staying informed through reputable sources to avoid unnecessary panic and misinformation.
