Michigan confirms sixth measles case of the year

Three more cases of wild poliovirus type 1 (WPV1) have been reported in Afghanistan, all from Kandahar, bringing the country’s total for the year to nine, the Global Polio Eradication Initiative said in its latest weekly update. The new cases put the country above the 2023 total of six.

Afghanistan is one of the few countries where WPV1 is still endemic. Last week, Pakistan, which also continues to battle the virus, reported more cases, also surpassing last year’s number. The country reported eight new environmental cases of WPV1 this week.
