The director of Health in Tonga says the kingdom needs to continue its work in preventing HIV-aids including educating on safe sex, to reach new United Nations targets.
The United Nations Global theme for World AIDS Day is 'Getting to zero, zero new HIV cases, zero discrimination and zero AIDS related deaths'.
Dr Siale Akauola says his ministry has been successful in keeping the number of HIV/aids cases in Tonga at 19 since 2012.
But Dr Akauola says they need to stay vigilant.
"We have to continue on the advocacy. Although we have to celebrate and give credit to the activities that have been done so far, the susceptibility of the public is not reduced. We are still seeing a high level of STIs, (Sexually Transmitted Infections), and teenage pregnancy so we have to protect people who are behaving in susceptible ways. We can't rest on our laurels."
