The Public Health Agency has advised that, due to the higher than usual rates of Group A streptococcus in the community at this time of year, it is not unexpected for schools to see cases.
Please see the linked Factsheet for useful information about the scarlet fever and other infections caused by Group A streptococcus.
If your child is unwell, they should not attend school. If your child is diagnosed with scarlet fever, they should stay at home and not attend school for at least 24 hours after starting the antibiotic treatment, to avoid spreading the infection.
