A norovirus outbreak in two Exeter schools has sent 45 students home with the severe vomiting bug.
Westclyst and Broadclyst Primary School saw the bug spread through its students, with parents claiming kids leaving the school with sick-shots.
One parent said it was "like a horror movie" when she wanted to pick up her four-year-old son at the end of the day.
Westclyst and Broadclyst schools are working with Public Health England to manage the Devon outbreak.
It is clear that more schools in the region are affected.

Another parent added, "My son literally started at school and it's only his second week.
"Yesterday afternoon, the parents estimated that about 70 were ill.
"The school has asked children to wash their hands, but the NHS website says it does not kill the virus.
"My son does not have it, but I keep him away from school because I have diabetes and a little baby at home and we can not risk having norovirus."
Director of the two schools Jonathan Bishop said: "In terms of numbers, Westclyst has five out of 15 children.
"In Broadclyst it's probably 40. Especially the one-year group is affected, we have nearly 600 children in both schools."
The outbreak started on Monday morning at school. Some students reportedly got sick at home over the weekend.
Head Mr. Bishop added, "Monday morning we did not have one or two at school because they were sick.
"Yesterday we came to school and we had a lot of people getting sick and we sent them home."
Norovirus, also known as the winter vomiting bug, is the most common stomach bug in the UK, affecting people of all ages.
The virus, which is highly contagious, causes vomiting and diarrhea, but usually not more than two days.
It can spread quickly through schools and workplaces and leads to hospital closures.
Norovirus can happen anytime, but outbreaks are more common in colder weather.
In winter, germs live longer outside the body, so they spread more easily.
Devon Council and Public Health England were asked for comment.
