WHO says vaccine-derived poliovirus detected in Papua New Guinea

  • Wild polio is only endemic in Pakistan and Afghanistan but vaccine-derived polio continues to cause outbreaks in wider range of countries
  • This is first polio outbreak in Papua New Guinea since 2018 when an outbreak was reported in the same area as the new detections, Lae city

The World Health Organization said on Tuesday that circulating vaccine-derived poliovirus type 2 (cVDPV2) had been detected in stool specimens of two healthy children in Papua New Guinea on May 9.

The detection of wild poliovirus or vaccine-derived poliovirus, including from samples taken from healthy children, is considered a serious public health event, WHO said in a statement.

It added that the detection of circulating type 2 poliovirus was classified as a “polio outbreak.”

Wild polio is only endemic in Pakistan and Afghanistan, but vaccine-derived polio continues to cause outbreaks in a wider range of countries. For example, this year, countries including Nigeria and Ethiopia, among others, have reported tens of cases of paralysis caused by polio.

This is the first polio outbreak in Papua New Guinea since 2018, when an outbreak was reported in the same area as the new detections, Lae city in Morobe province.

Vaccination protects against all forms of polio, but coverage rates in Papua New Guinea are only around 44 percent for the third dose needed for protection, the WHO said. Efforts are now underway to detect further transmission and boost vaccination coverage in the affected area.

Poliomyelitis, which is spread mainly through the faecal-oral route, is a highly infectious virus that can invade the nervous system and cause paralysis and death in young children, with those under 2 years old most at risk. In nearly all cases it has no symptoms, making it hard to detect.

Rubio says new governance bodies for Gaza will be in place soon

  • Rubio said progress had been made recently in identifying Palestinians to join the technocratic group and that Washington aimed to get the governance bodies in place “very soon,” without offering a specific timeline.

WASHINGTON: US Secretary of State Marco Rubio said that a ​new governance structure for Gaza — made up of an international board and a group of Palestinian technocrats — would be in place soon, followed by the deployment of foreign troops, as the US hopes to cement a fragile ceasefire in Israel’s war in the Palestinian enclave. 
Rubio, speaking at a year-end news conference, said the status quo was not sustainable in Gaza, where Israel has continued to strike Hamas targets while the group has reasserted its control since the October peace agreement ‌brokered by the US.
“That’s why we have a sense of ‌urgency about ​bringing ‌phase one to its full completion, which is the establishment of the Board of Peace, and the establishment of the Palestinian technocratic authority or organization that’s going to be on the ground, and then the stabilization force comes closely thereafter,” Rubio said.
Rubio said progress had been made recently in identifying Palestinians to join the technocratic group and that Washington aimed to get the governance bodies in place “very soon,” without offering a specific timeline. Rubio was speaking after the US Central Command hosted a conference in Doha this week with partner nations to plan ‌the International Stabilization Force for Gaza. 
Two US officials said last week that international troops could be deployed in the strip as early as next month, following the UN Security Council’s November vote to authorize the force.
It remains unclear how Hamas will be disarmed, and countries considering contributing troops to the ISF are wary that Hamas will engage their soldiers in combat.
Rubio did not specify who would be responsible for disarming Hamas and conceded that countries contributing troops want to know the ISF’s specific mandate and how it will be funded. 
“I think ⁠we owe them a few more answers before we can ask anybody to commit firmly, but I feel very confident that we have a number of nation states acceptable to all sides in this who are willing to step forward and be a part of that stabilization force,” Rubio said, noting that Pakistan was among the countries that had expressed interest.
Establishing security and governance was key to securing donor funding for reconstruction in Gaza, Rubio added.
“Who’s going to pledge billions of dollars to build things that are going to get blown up again because a war starts?” Rubio said, discussing the possibility of a donor conference to raise reconstruction funds. 
“They want to know ‌who’s in charge, and they want to know that there’s security so and that there’ll be long term stability.”
