[h=3]More polio recorded in Pakistan, Nigeria[/h] According to the latest weekly update from the Global Polio Eradication Initiative (GPEI), both Pakistan and Afghanistan recorded new polio cases in the past week.
Pakistan has two new cases of wild poliovirus type 1 (WPV1), in Sindh and Khyber districts. The case-patients experienced onset of paralysis on Sep 22 and 25, respectively. Officials have now reported six WPV cases in Pakistan this year, one more than at this time in 2017.
"The detection of new cases and environmental-positive samples is not unexpected at this time, and underscores the fact that transmission is ongoing in the country," GPEI said. Pakistan, along with neighboring Afghanistan as well as Nigeria, is one of three countries in the world with endemic polio transmission.
In Nigeria, a new case of circulating vaccine-derived poliovirus type 2 (cVDPV2) was recorded in Katsina, the site of other recent cases. That patient experienced paralysis onset on Sep 16. The new case brings Nigeria's year-to-date total of cVDPV cases to 17. Nigeria had no cVDPV cases last year.
Globally, there have been 22 WPV cases and 69 cVDPV cases since the start of the year.

[h=3]CDC ends probe of Salmonella outbreak tied to Gravel Ridge eggs[/h] In its final update on a Salmonella Enteritidisoutbreak tied to contaminated eggs produced by Gravel Ridge Farms of Cullman, Ala., the Centers for Disease Control and Prevention (CDC) announced 6 more cases, raising the total to 44, and said 4 more states were affected, raising that number to 11.
There were 12 hospitalizations during this outbreak, but no deaths. Tennessee reported the most cases, with 25, followed by Alabama (7), and Ohio (4). The other affected states?Colorado, Georgia, Iowa, Kentucky, Maryland, Montana, New York, and Texas?recorded 1 case each.
Illness-onset dates ranged from May 17 to Aug 26, with patients' ages ranging from 1 to 94 years old. Twenty-six (81%) of 32 people interviewed reported eating restaurant dishes made with eggs in the week prior to illness.
Whole-genome sequencing collected from three patients and one food sample did not show antibiotic resistance.
"As of October 25, 2018, this outbreak appears to be over," the CDC said, adding, "Consumers and restaurants should always handle and cook eggs safely to avoid foodborne illness from raw eggs."
Epidemiologic investigations showed that shell eggs from Gravel Ridge Farms were the source of the outbreak, and on Sep 8 the company recalled cage-free large eggs with use-by dates of Jul 25 through Oct 3.
