Flu and other respiratory illnesses are currently circulating and are likely to continue to increase in coming weeks, the PHA has warned.
High numbers of scarlet fever, which is caused by group A streptococcus, also continue to be reported. On Tuesday, the Public Health Agency (PHA) issued advice amid the rise in cases.
It urged all people eligible for the free flu and Covid-19 vaccines, who have not yet been vaccinated, to get it now and called on the parents of pre-school and school-aged children to get them vaccinated against flu.
