Within weeks of exposure, virus levels peak and then decline to levels that may remain low for months or years. It...Dealing deadly cancers a knockout punch
...in about two-thirds of all human cancers. Reovirus enters a cancer cell, makes thousands of copies of itself, and then causes the cell to burst, which releases viruses that infect and kill adjacent cancer cells. Normal cells are not harmed.

A voltage is applied to the needle, generating ions around its tip that repel the oppositely charged ions close to it.
