Health chiefs have confirmed that contact tracing is being carried out at 14 East Ayrshire schools.
NHS Ayrshire & Arran has revealed a list of schools hit by coronavirus in the last 10 days.
Every secondary school in the region has also been affected by the virus too.
It comes as Kilmarnock Academy ordered all S2 students to stay at home after pupils in the year group tested positive for the virus.
Lynne McNiven, director of public health, said that schools impacted by Covid may not necessarily have Delta variant involvement.
Ms McNiven added: "Contact tracing has taken place in the following East Ayrshire schools between the period of 05/06/2021 – 14/06/2021.
"Please note that this does not necessarily mean a school outbreak.
"Some will have sporadic cases and clusters.
"As schools are part of our communities, when cases are identified within school settings there may be a link with the places and people who live in the nearby area.
"This may not necessarily have Delta variant involvement."
