⚠️ A deadly new COVID-linked disease has just emerged.
A rare but potentially fatal autoimmune disease is surging in the UK—and researchers believe COVID-19 may be to blame.
Known as anti-MDA5 positive dermatomyositis, the condition causes the immune system to attack lung tissue, leading to progressive scarring (interstitial lung disease) and, in many cases, death. Once mainly observed in Asian populations, the disease has now emerged in northern England, with doctors in Yorkshire reporting 60 new cases between 2020 and 2022, including eight fatalities. What’s alarming is that most patients had no known prior COVID-19 infection, suggesting even mild or asymptomatic cases could trigger this life-threatening immune response.
The newly identified condition, now called MIP-C (MDA5-autoimmunity and Interstitial Pneumonitis Contemporaneous with COVID-19), may represent a distinct post-COVID phenomenon.
Researchers found that affected individuals had elevated levels of interleukin-15 (IL-15)—an inflammatory molecule linked to severe lung damage.
Though only a fraction of patients had confirmed COVID-19 tests, the rise in cases closely followed pandemic waves and coincided with mass vaccinations, prompting scientists to suspect a link between SARS-CoV-2 exposure and the onset of MIP-C. With similar reports now emerging worldwide, experts warn this could be a global public health concern.
