With the highly contagious Omicron variant driving infections, millions visit labs and pharmacies weekly for PCR or antigen tests to detect COVID-19. These tests have become routine amid packed schedules. Sud Ouest reported at least 1.6 million tests performed last week alone. But after multiple close contacts and repeated testing, is there a real health risk?
The Academy of Medicine has cautioned that repeated nasopharyngeal swabs aren't risk-free. In an April press release, they highlighted potential issues from repeated sampling. The test itself isn't the culprit—it's often improper technique. Common side effects include discomfort, pain, or minor nosebleeds. Rumors of meningitis have circulated, but Dr. Nicolas Boulanger, an ENT specialist and cervico-facial surgeon, told 20 Minutes this is extraordinarily rare. "I can't even imagine how it could occur with this swab type. Rest assured, meningitis risk is virtually nonexistent after PCR or antigen tests."
Poor or repeated sampling heightens risks. "This procedure, if mishandled or overdone, can indeed cause pain and bleeding," confirms Dr. Boulanger. Proper technique is essential for safety. "Many people have deviated septums causing obstruction. Repeated swabs lead to friction and minor mucosal bleeding," he adds.
