EMH: I hope to unleash an army of modified Borg nanoprobes into his bloodstream, designed to target and eradicate the infection. As you know, I've been analysing the nanoprobes. They're efficient little assimilators, one can't help but admire the workmanship, but they're no match for the alien cells. So I successfully dissected a nanoprobe and managed to access its re-coding mechanism. I reprogrammed the probe to emit the same electrochemical signatures as the alien cells. That way, the probe can do its work without being detected. Observe. The alien cells are completely oblivious to the probe until it's too late. Unfortunately, I've only created a few prototypes. I'll need several days to modify enough nanoprobes to cure Ensign Kim.
