PBS NewsHour reports on polio eradication efforts underway in India’s Uttar Pradesh and Bihar states, which “have been the source of all the polio viruses that have crippled children in India, … one of four countries in the world where polio is still endemic, though it appears it may be on the cusp of finally halting transmission,” according to the news service.

“Nearly every month the effort is mounted” as “[a]n army of vaccinators tries to find every child five and younger,” the news service writes. The teams, consisting primarily of women, “visit each house, shanty and tent on their routes, dripping orange polio vaccine into grimacing mouths,” PBS notes (Branswell, 8/16).
