Anne Wilson, headteacher at Fircroft Primary School, said Imani Green, who suffered from sickle cell anaemia, "coped very well" with her condition which forced her to stay indoors at play time to avoid getting cold.
The school had granted her permission to spend time in Jamaica because the warmth was known to be better for health.
Mrs Wilson told Sky News:
We felt it was in Imani's best interest to be there rather than here at this time. Today and for the next few days and weeks it's going to be difficult for them but we're here to support them.
