Senate Majority Leader Juan Miguel Zubiri announced he tested positive for COVID-19 again, despite recovering from the illness in April.
A confirmatory swab test conducted by the Philippine Red Cross showed him to be negative for COVID-19.
Zubiri stated that doctors believe the earlier positive test may have detected remnants of dead virus cells, as the Philippine Red Cross' PCR machines can distinguish between live and dead RNA.
Despite the negative result, Zubiri will remain in quarantine for the prescribed period to ensure he is no longer contagious.
He will continue to work virtually from isolation.
