GeoSentinel Network Members are requested to contact GeoSentinel for any Alarming Clinical Event.  In addition to the listed specific diagnoses, GeoSentinel is interested in hearing of anything that a Network Member thinks is unusual or worthy of comparing notes with the experience of other Network Members.

Eligibility Criteria:

Any traveler, immigrant, or refugee, who has crossed international borders in the previous 1 year and where in the best clinical judgment of the GeoSentinel Network Member, the current illness was acquired as a function of that travel.

How to Contact GeoSentinel:

	Send an informal e-mail with a very brief description of the diagnosis and circumstances to a specified e-mail address.
	OR
	Fill out an On-line form and submit a very brief description of the diagnosis and circumstances.  Provide as much information as is readily available and convenient.  Submit the form even if not totally complete.

The e-mail may be as brief as "42 year old returned from Mexico last week with encephalitis" but preferably should contain at least age, countries of likely acquisition of illness, pertinent clinical and lab findings.  Long pieces pasted from existing patient records are acceptable as long as specific patient identifiers are removed.
