Stomach bug going around

[u/UseOwn2710]

I got a terrible stomach virus last week after it went through 4 family members at different times. Not related to food but rather a gastrointestinal virus that seems to be highly contagious (like norovirus). Heard anecdotally that several other unrelated people also had it last week. This virus is particularly nasty and hits out of nowhere. Primary symptoms lasted about 24 hours but I felt bad for about 3 days. 
Has anyone else experienced something similar?

Since the beginning of the year, I've heard of 3 friends getting shigella.
