Pathogens

A smaller, but still dangerous, concentration of pathogens won't necessarily be detectable by smell.

The exact location of the trees is a secret because of fears that visitors could bring in pathogens that might cause disease.

New studies by the Global Virome Project, a worldwide effort to increase preparedness for pandemics, indicate the world can expect about five new animal-borne pathogens to infect humans each year, creating a sense of urgency to curb the wild animal trade.

Antibiotic resistance, in which microbes no longer respond to drugs, is quickly becoming a global health emergency. Of particular concern are so-called “superbugs,” a handful of pathogens that patients acquire in hospitals and other health care settings. Patients recovering from surgery are particularly vulnerable to the resistant, hospital-borne infections, which put them at high risk of death.
