Papua New Guinea's prime minister, James Marape, says the nation is facing a health crisis like it's never had to face before.
PNG is struggling to cope with the latest outbreak of the Delta strain with the reported death toll now exceeding 300, but the actual figures are thought to be much higher.
Hospitals in the biggest cities, Port Moresby, Lae, Mt Hagen and Goroka are full, with deaths from the virus now a daily occurrence.
Marape said people can help with the outbreak by sticking to the health messages, and getting vaccinated.
"I encourage all citizens to go down the path of vaccination, scientifically proven, there are less who die from the side effects of the vaccines than those who die from being infected with the coronavirus," he said.
Marape said those who do not want to get vaccinated, must limit their movements and stay away from crowds to limit their exposure to Covid-19.
He said PNG has never had to face a health crisis like this.
"It is indicated that we have a third wave in as far as Covid-19 explosion is concern and it is important at this time we must all know that the Delta strain of Covid-19 is now amidst us and is spreading," Marape said.
