A group of parents in Gainesville, FL, concerned about potential harms from masks, submitted six face masks to a lab for analysis.

The analysis detected the following 11 alarmingly dangerous pathogens on the masks:

• Streptococcus pneumoniae (pneumonia)

• Mycobacterium tuberculosis (tuberculosis)

• Neisseria meningitidis (meningitis, sepsis)

• Acanthamoeba polyphaga (keratitis and granulomatous amebic encephalitis)

• Acinetobacter baumanni (pneumonia, blood stream infections, meningitis, UTIs— resistant to antibiotics)

• Escherichia coli (food poisoning)

• Borrelia burgdorferi (causes Lyme disease)

• Corynebacterium diphtheriae (diphtheria)

• Legionella pneumophila (Legionnaires' disease)

• Staphylococcus pyogenes serotype M3 (severe infections—high morbidity rates)

• Staphylococcus aureus (meningitis, sepsis)

Half of the masks were contaminated with one or more strains of pneumonia-causing bacteria. One-third were contaminated with one or more strains of meningitis-causing bacteria. One-third were contaminated with dangerous, antibiotic-resistant bacterial pathogens. In addition, less dangerous pathogens were identified, including pathogens that can cause fever, ulcers, acne, yeast infections, strep throat, periodontal disease, Rocky Mountain Spotted Fever, and more.
