Approximately two million people carry a strain of drug-resistant bacteria in their noses, according to new research in the Journal of Infectious Diseases. The Centers for Disease Control conducted the research, which is the first reliable nationwide estimate of colonization with staphylococcus aureus, including methicillin-resistant staphylococcus aureus (MRSA).

Researchers collected samples from nearly 10,000 participants in the 2001-2002 National Health and Nutritional Examination Survey, making a representative sample of the U.S. population. Staph colonized nearly one-third of the samples. Males and children between six and 11 years old had the highest prevalence of the bacteria. MRSA prevalence was 0.8% across the entire sample.
