While PHE says that it remains unlikely people infected in Guinea, Liberia or Sierra Leone could arrive in the UK, it warns it is not impossible.
Included within the guidance is a flowchart to help staff who work at early years settings and schools understand what to do if they have children returning or visiting from affected countries, and how to put in place infection control if they believe they may have the virus.
The flowchart explains how to assess an unwell child, with symptoms to look out for, and what to do if they believe a child may have Ebola, including placing the child in isolation in a separate room.
PHE advises that there should be no restrictions on children attending nursery or school if they have travelled to the UK from any of the affected countries and are free of symptoms.
The time between infection and symptoms first appearing of Ebola ranges from two to 21 days.
Only people with symptoms of Ebola - fever, diarrhoea and vomiting - can infect others. The virus is spread only by direct contact with the blood or body fluids of someone with Ebola.
