More vaccine-derived polio cases reported in Africa, Papua New Guinea
Four countries reported more vaccine-derived polio cases in ongoing outbreaks, according to the latest weekly update today from the Global Polio Eradication Initiative (GPEI) today.
In Niger, officials reported a circulating vaccine-derived poliovirus type 2 (cVDPV2) case in a patient from Zinder province who had an Aug 14 paralysis onset. The virus is genetically linked to cVDPV2 circulating in Nigeria's Jigwa state. The new case raises Niger's total for 2018 to three, all of which are in Zinder province, with links to Jigwa state in Nigeria.
Meanwhile, Nigeria reported two new cVDPV2 cases in patients from Katsina and Borno states. The patients first experienced paralysis in August and mid September, and both cases are linked to an ongoing outbreak centered around Jigwa state. Nigeria has now reported 16 cVDPV2 cases for the year.
Somalia reported one new cVDPV2 case in a patient from Lower Juba with a Sep 2 paralysis onset, pushing the country's total to 12 in 2018.
Elsewhere, Papua New Guinea reported one new case in its cVDPV1 outbreak. The patient from East Sepik had an Aug 1 paralysis onset. The country has now registered 15 cases in its outbreak, which began at the end of June and prompted an immunization campaign, the fourth stage of which began on Oct 8.

Israel confirms first imported monkeypox case
Israel's health ministry today reported an imported monkeypox case, which—like two recent imported cases in the United Kingdom—involved a patient who had been in Nigeria, where the virus is endemic.
The patient is an Israeli man who lives and works in Port Harcourt in southern Nigeria, according to a health ministry statement translated and posted by Avian Flu Diary (AFD), an infectious disease news blog. The man's symptoms began about a week after he returned from Nigeria, and his infection was confirmed at Shaare Zedek Medical Center in Jerusalem.
According to the report, his condition is improving, and he is in home isolation.
Nigeria has been experiencing a monkeypox outbreak since September 2017, piling up 269 cases, 115 of them lab-confirmed, according to an Oct 5 update from the World Health Organization (WHO). Disease activity there led to the two UK imported cases, plus an infection in a healthcare worker who treated one of the patients.

Chinese officials confirm new H5N6 avian flu outbreak in backyard birds
Chinese agriculture officials today confirmed a new highly pathogenic H5N6 avian flu outbreak, this time in backyard birds in Hunan province in the southern part of the country, according to a World Organization for Animal Health (OIE) report. The outbreak was reported by local officials earlier this week.
The outbreak began on Sep 26, killing 385 and sickening 516 birds among a flock of 1,414. All surviving birds were culled to prevent further disease spread. Officials said the outbreak is ongoing.
Response steps include controlling poultry movement, heightened surveillance in the area, disposal of carcasses, and disinfection of the premises. Chinese officials reported previous H5N6 outbreaks to the OIE in March and in late September.
