Without infecting people, this bug, or at least its DNA footprint, appears to make trouble, although not so much that the 40 healthy people who turned out to be harboring it noticed anything amiss. It took a test to find an effect in humans, then to corroborate the results in mice, ultimately linking the algae virus traces to slightly diminished mental functions, including attention, spatial orientation...
