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.

Filmmakers defend Berlin festival chief in Gaza row

  • Actors and filmmakers rushed to defend the head of the Berlin film festival Thursday following a media report that her job was on the line over a director’s anti-Israel speech at the event
BERLIN: Actors and filmmakers rushed to defend the head of the Berlin film festival Thursday following a media report that her job was on the line over a director’s anti-Israel speech at the event.
Syrian-Palestinian filmmaker Abdallah Al-Khatib kicked off a controversy during Saturday’s closing ceremony by accusing Germany of being complicit in genocide in Gaza through its support for Israel.
German tabloid Bild had reported that Tricia Tuttle was due to be dismissed at an emergency meeting on Thursday, citing sources close to state-owned KBB, the company that runs the festival.
Culture minister Wolfram Weimer’s office confirmed the meeting had taken place but made no mention of Tuttle being sacked, stating that discussions had been “constructive and open” and would “continue in the coming days.”
A group of cinema luminaries including Tilda Swinton, Todd Haynes, Sean Baker and Tom Tykwer signed an open letter defending the Berlinale as a forum for free expression.
“As filmmakers in Germany and beyond, we are following the debates surrounding the Berlinale and the discussion about the dismissal of Tricia Tuttle with great concern,” they wrote. “We defend the Berlinale for what it is: a place of exchange.”
Angry rows over the Israel-Palestinian conflict have repeatedly rocked the Berlinale, held every February as Europe’s first major film festival of the year.
Environment Minister Carsten Schneider walked out of Saturday’s closing ceremony, labelling Khatib’s remarks “unacceptable.”
Germany, as it has sought to atone for the horrors of the Holocaust, has been a steadfast supporter of Israel, and criticism of Israel’s conduct in Gaza has been more muted than in many other countries.
Conservative lawmaker Ellen Demuth was among those who condemned the “antisemitic incident” at the awards ceremony and urged “a fresh start at the top of the film festival.”
The Berlinale Team in an Instagram post meanwhile defended Tuttle, praising her “clarity, integrity and artistic vision.”
The writers’ association PEN Berlin said Khatib’s comments were protected by freedom of expression and that if Tuttle were to be sacked over them, it would cause “immense damage” to the festival.
“Such wanton destruction of the German cultural scene, such self-inflicted insularity, must not be allowed to happen,” it said.
The backdrop of the Middle East conflict led to a tense 76th edition of the festival from the start.
More than 80 film professionals criticized the Berlinale’s “silence” on the Gaza war in an open letter, accusing the festival of censoring artists “who reject the genocide” they believe Israel has committed in Gaza.
Award-winning Indian writer Arundhati Roy withdrew from the festival after the jury president, German director Wim Wenders, said cinema should “stay out of politics” when asked about Gaza.
