From the UK Independent:
Virus that 'makes humans more stupid' discovered
A virus that infects human brains and makes us more stupid has been discovered, according to scientists in the US.
The algae virus, never before observed in healthy people, was found to affect cognitive functions including visual processing and spatial awareness.
Scientists at Johns Hopkins Medical School and the University of Nebraska stumbled upon the discovery when they were undertaking an unrelated study into throat microbes.
A bit more:
Of the 90 participants in the study, 40 tested positive for the algae virus. Those who tested positive performed worse on tests designed to measure the speed and accuracy of visual processing. They also achieved lower scores in tasks designed to measure attention.
Like I said, this could explain a lot.
Major outbreaks soon to be detected in New York City, Los Angeles and Washington D.C.???
