Well, it’s because symptomatic doesn’t always mean infectious.
If you’re vaccinated or have pre-existing immunity symptoms will kick in quickly after exposure.
You’ll feel unwell but high levels of the virus won’t be overloading your system.
While you’re symptomatic and reaching for a test earlier, chances are you aren’t yet infectious.
If you’re unvaccinated and without this immunity, symptoms are slower to show, but the virus grows faster.
PCR tests can pick up the virus at these lower levels, but RATs may remain negative for 1-3 days. A positive RAT test will kick in when you become infectious.

Sometimes when a business is growing, it needs a little help.
Right now Kaniva News provides a free, politically independent, bilingual news service for readers around the world that is absolutely unique. We are the largest New Zealand-based Tongan news service, and our stories reach Tongans wherever they are round the world. But as we grow, there are increased demands on Kaniva News for translation into Tongan on our social media accounts and for the costs associated with expansion. We believe it is important for Tongans to have their own voice and for Tongans to preserve their language, customs and heritage. That is something to which we are strongly committed. That’s why we are asking you to consider sponsoring our work and helping to preserve a uniquely Tongan point of view for our readers and listeners.
