Nasal Swab Doesn't Cause Inflammation

Social media users claimed that the area sampled during a COVID-19 nasal swab is a part of the body called the blood-brain barrier. Users attached an image to the post that associates the blood-brain barrier with the target site for the sample collection.



The claims state that if the blood-brain barrier is compromised by contaminated test, a condition called “leaky blood-brain barrier,” or inflamed brain, results. This can lead to bacterial infection, toxin exposure, a whole host of syndromes and diseases, and ultimately death.
