A computer virus that makes you sick

If you suffer from photosensitive epilepsy, migraines or the wonk go read about pies or something.
What if a computer virus could make you sick. The idea was described in the novel “snow Crash” where one character becomes a "just a jittering cloud of bad digital karma"

Pickover describes patterns that can induce migraines in people. I am stupic enough to test them and they do work. Still you have to look at them for a while so not a particularly effective attack.

Photo sensitive epilepsy occurs in about 2 in 10,000 people. Pokemon caused attacks in about 700 children in Japan by flashing lights during the program.
Yeah that links to the video so be careful.

This video is not on a full screen is slightly changed, looking at it in a darkened room, being a child and having a really good screen would all make it more dangerous. Flashes at 4 hertz or some multiple of that seem to cause these effects but less then !% effectiveness hardly makes a successful weapon,

Darren Brown did something similar in the most terrifying piece of television I have ever seen

He puts the figure on how many people you can cause to go into a trance at about 1/3.

Sound does not seem much use as a weapon. You can prevent people talking by replaying their speech with a delay. But that hardly will incapacitate people.

Sea sickness could be induced by out of focus screen or slightly shifting text. Any other ideas on how to catch a computer virus?
