Last case of the Andes virus confirmed to be caused by a sequence of human-to-human transmission from the MV Hondius outbreak. 

An explicit chain of infections need not be established for the case to be considered linked to the outbreak, as long as there is consensus among epidemiologists that the case is most likely linked.

Options will resolve NO whenever a new case is confirmed after the threshold date. Remaining options will resolve YES once no new cases are reported for 10 weeks.

I will take the date the case is confirmed by relevant health authorities, using their local time zone, even if the case is considered "suspected" or "symptomatic" earlier.

I will not trade on this market. I reserve the option to modify the details of the question based on comments here in the first 24 hurs.
