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.

Poland slow to counter Russia’s ‘existential threat’: general

  • The general highlighted a low “pace of technical modernization,” compared to increases in the army’s size
  • Kukula said the Polish army should reach 500,000 soldiers by 2039

WARSAW: Russia poses an “existential threat” to Poland and its military is lagging, the country’s armed forces chief warned senior officials on Wednesday.
Poland, the largest country on NATO’s eastern flank and a neighbor of Russia, Belarus, and Ukraine, is the western alliance’s largest spender in relative terms.
This year, the country is allocating 4.8 percent of its GDP to defense, just shy of the alliance’s five percent target to be met by 2035.
However, that record defense spending was not enough to “make up for nearly three decades of chronic underfunding of the armed forces,” General Wieslaw Kukula, chief of the general staff, argued at the meeting, which included top officers, the defense minister and Poland’s president.
The general highlighted a low “pace of technical modernization,” compared to increases in the army’s size.
Kukula said the Polish army should reach 500,000 soldiers by 2039, compared with around 210,000 at present.
As a result of a lack of updates, some new Polish units “are not achieving combat readiness,” due to insufficient equipment, rather than a personnel shortage, the general argued.
Meanwhile, he added, “the Russian Federation remains an existential threat to Poland.”
Russia “is constantly reorganizing its forces, drawing on the lessons from its aggression in Ukraine, and building up the capacity for a conventional conflict with NATO countries,” he stressed.
Poland is to receive 43.7 billion euros ($51,5 billion) in loans under the European Union’s Security Action For Europe (SAFE) scheme, designed to strengthen Europe’s defensive capabilities.
Warsaw plans to use these funds to boost domestic arms production.
The Polish government claims that Poland will be able to access SAFE finance even if President Karol Nawrocki — backed by Poland’s conservative-nationalist opposition — vetos a law setting out domestic arrangements for its implementation.
Law and Justice (PiS) — the main opposition party — argues that SAFE could become a new tool for Brussels to place undue pressure on Poland, thanks to a planned mechanism for monitoring the funds, which they claim risks undermining Polish sovereignty.
