Source Limitation
I notice that you've requested a comprehensive summary incorporating multiple perspectives from different source types.
“There’s a virus you may have never heard of before that is estimated to infect up to 90 percent of people and lurks quietly in your cells for life—but if it becomes activated, it will destroy your brain”
But I only have one source article from Ars Technica provided.

To create the 4-6 paragraph summary you're requesting with the required 3-5 citations from different source types per paragraph, I would need additional source articles.
The Ars Technica article provides information about JC virus infecting up to 90% of people.
But I cannot create citations from sources that weren't provided in the article snippets.
