Angola, Ethiopia, Pakistan report new polio cases

Two countries in Africa and Pakistan have recorded new polio cases in the past week, according to an update today from the Global Polio Eradication Initiative (GPEI).

Pakistan has reported two wild poliovirus type 1 (WPV1) cases in Shangla and Bannu districts in Khyber Pakhtunkhwa province, with onset of paralysis on May 18 and 24. The cases raise Pakistan's total in 2019 to 24.

A circulating vaccine-derived poliovirus type 2 (cVDPV2) was confirmed in Angola, in a patient with acute flaccid paralysis (AFP) who experienced onset of paralysis on Apr 5. The case-patient lives in Lunda Norte province, which borders the Democratic Republic of the Congo (DRC). GPEI said DRC has been monitoring cVDPV2 outbreaks since 2017.

An AFP patient in Somali province, Ethiopia, also tested positive for cVDPV2. The patient reported an onset of paralysis on May 20.

"Genetic sequencing confirms that the isolated virus is linked to an ongoing cVDPV2 outbreak detected in the Horn of Africa in 2018, with cases reported in Somalia as well as from an environmental sample in Kenya," the GPEI said.

CDC ends investigation into 209-case E coli outbreak tied to ground beef

The Centers for Disease Control and Prevention (CDC) announced an end to its investigation  of an Escherichia coli O103 outbreak linked to contaminated ground beef.

The outbreak resulted in 209 illnesses reported in 10 states—13 more cases than in the agency's last update on May 13. No deaths were recorded, but 29 people were hospitalized for their infections. Two cases of hemolytic uremic syndrome, a type of kidney failure, were reported.

"This outbreak appears to be over. Ill people in this outbreak ate ground beef from many sources. No single supplier, distributor, or brand of ground beef was identified," the CDC said.

On Apr 24, Grant Park Packing of Franklin Park, Illinois, recalled approximately 53,200 pounds of raw ground beef products distributed to restaurants. The day before, K2D Foods, doing business as Colorado Premium Foods in Carrolton, Georgia, recalled 113,424 pounds of ground beef.

Patients reported symptom onset from Mar 1 to May 1. Of 159 people interviewed, 125 (79%) reported eating ground beef in the week prior to illness.

Kentucky and Tennessee recorded the most cases, with 76 and 59 cases respectively. Georgia reported 51.

More H5 avian flu confirmed in Namibian penguins, Taiwanese poultry

In the latest highly pathogenic avian flu developments with wild birds and poultry, Namibia reported three more detections in penguins and Taiwan reported three more poultry events involving H5N2, according to notifications from the World Organization for Animal Health (OIE).

Namibia reported its first H5N8 outbreak in February at a penguin breeding site on Halifax Island. Yesterday it reported two others that occurred in February, one on Halifax Island and the other on Ichaboe Island. The third outbreak began on Jun 20 on Mercury Island, another coastal seabird conservation area. Taken together, the outbreaks killed 238 jackass penguins. Officials said the source of the virus is migratory waterfowl.

Taiwan's latest H5N2 events are part of outbreaks in poultry that have been under way since 2015. The three outbreaks began between May 27 and Jun 8. One involved discarded dead geese in Yunlin County, a second occurred in native chickens at a slaughterhouse in Taipei City, and the third involved native chickens at a farm in Yunlin County.

Among the three outbreaks, the virus killed 594 of 12,505 susceptible birds.
