After the imposition of travel restrictions on the heels of a “public health emergency” by the WHO, Pakistan is taking a proactive approach: The Polio vaccine is being distributed across the nation’s international airports, in the hope of stemming the disease’s advancement.

“Special measures will include establishing mandatory immunisation counters on all airports, border crossings and seaports for all travellers,” said ministry spokesman Sajid Ali Shah.

According to the BBC, the decree came without warning to the Pakistani business community. It’s also unclear to what degree government officials have actually considered the logistics of disseminating the vaccine. Officials say the restrictions imposed by the WHO actually do more harm to Pakistan than good.

“By recommending travel restrictions on Pakistan, the WHO has strengthened those forces who actually banned polio drops,” said Shah.

Before traveling abroad, all those who wish to leave Pakistan must receive the vaccine anywhere from four weeks to one year prior to departure. That includes long-term visitors without certification of vaccination. Officials were not yet sure whether the restrictions apply to non-residents. According to the WHO, Pakistan recorded 91 cases of polio last year, up from 58 in 2012. It has also recorded 59 of the world’s 74 cases this year.

Polio is an acute, viral, infectious disease spread from person to person, primarily via the fecal-oral route. Though largely extinct here in the west, polio is still endemic to South Asia and Africa, particularly Pakistan and Nigeria.
