Public health officials can identify the outbreak of disease by monitoring certain patterns of behavior through syndromic surveillance. Which of the following is one of the signs used to identify a disease outbreak using this system?

  • Sorry, that’s incorrect.

    In syndromic surveillance, all of the above are used in addition to other patterns that suggest an outbreak. Despite the emergence of this innovative surveillance method, most surveillance still depends on tracking reported infections.

Which deadly pathogen cannot be found naturally in the wild:

  • Sorry, that’s incorrect.

    Smallpox cannot be found naturally in the wild. Smallpox was officially declared eradicated from the globe in 1980, after an 11-year WHO vaccination campaign—the first human disease to be eliminated as a naturally spread contagion. Today, the virus remains only in laboratory stockpiles.
