Usage Note
Viral covers both the medical sense — infección viral (viral infection) — and the digital/social-media sense of content spreading rapidly, un vídeo viral. The social-media sense is a direct borrowing of English viral and is now fully established in Spanish. Note there is no written accent: stress falls naturally on the final syllable.
Examples
"El vídeo se hizo viral en pocas horas."
Natural Translation
The video went viral in a few hours.
