Besides bioterrorism, what is the most likely cause of infection?

Bioterrorism is rare. Please send your question to healthtap again, but add some details to help us answer you concerns. Thanks!
Not Bioterrorism. Bioterrorism is a very rare cause of infection. Most infections are caused by microorganisms naturally invading the body through a break in the skin, inhalation into the throat or lungs or through ingestion into the intestinal tract. These pathogenic organisms frequently colonize prior to infecting.
