The latest data published by the Public Health Agency (PHA) show that flu activity decreased last week [15th January – 21st January 2018]. However activity still remains at moderate levels, so the PHA is reminding everyone of importance of hand hygiene and self-care when preventing and managing colds and flu. Dr Jillian Johnston, Consultant at the PHA, said: “We may have seen a reduction in the prevalence of flu last week, but we shouldn’t become complacent. The fact remains that people are still falling ill with flu, so we should all take steps to prevent its spread.
