Health authorities have been urged to get their flu shot amid concerns about waning immunity after the territory has recorded a spike in influenza cases over recent weeks.

ACT chief health officer Kerryn Coleman said ACT Health was undergoing planning around testing for various respiratory illnesses. There were concerns people would not come forward for influenza testing, especially if they have already tested negative for COVID-19.

"It can be concerning that with so much focus on COVID that people forget there are other illnesses and other reasons why you might need to visit your health practitioner," Dr Coleman said.
