For how we live.
Cold sores heal on their own in about a week, and nothing clears the virus for good. Creams and pills shave hours to roughly a day off an episode — but only if started at the first tingle.
Taken as prescribed, oral PrEP cuts the risk of getting HIV from sex by about 99%, the CDC says. But randomised trials measured 44% to 86% — because the protection depends almost entirely on taking it.
The two most-prescribed respiratory antivirals sit at opposite ends of the evidence. One shortens flu by less than a day on average; the other cut serious outcomes sharply — but only in the group at real risk.
Xocova is taken after a known exposure, not after symptoms appear. In a 2,041-person trial it cut symptomatic infection by 67% through day 10.
In a controlled human infection trial, high-dose mosnodenvir suppressed DENV-3 far below placebo. Resistance-associated changes appeared in every sequenced recipient and none of the placebo group.
