Two more cases of Covid-19 have been confirmed in the Papua New Guinea capital of Port Moresby.
EMTV reported the latest cases include a 53-year-old man with no travel history and a 39-year-old medical officer, bringing the total number of infections to 19.
Deputy Controller, Paison Dakulala, expressed concern the last five positive cases had been health workers.
He said there had also been symptomatic people who had not stayed home and remained socially active.
Controller and Police Commissioner David Manning said says the latest statistics were alarming.
He said there had been 200 tests over the past five days which had revealed seven cases.
Mr Manning said the capacity at the local isolation facility was 70 and the current daily infection rate meant this had the potential to be reached by the end of the month.
This week a cancer patient who died at Port Moresby General hospital was found to have Covid-19 during a post-mortem examination.
Earlier the government announced a cluster outbreak at the Central Public Health Laboratory on the hospital premises.
