The word 'viral' is often used to describe something that becomes really popular or spreads quickly, like a video or a social media post. It can also refer to a disease or illness that spreads rapidly from person to person. For example, if a funny video gets shared by a lot of people on social media, you could say it has gone viral. Or, if there is a virus going around and a lot of people are getting sick, you could say it's a viral illness.
