“A large polio outbreak in Tajikistan â€“ Europe’s first in years â€“ has the potential to further spread the dangerous virus to other regions of the world, the [editors of] the Canadian Medical Association Journal [CMAJ] warned Wednesday” in an editorial appearing in the journal, the Canadian Press reports.
U.N. Secretary-General Ban Ki-moon on Monday “launched a national polio vaccination campaign in Angola, where the crippling disease has returned despite being eradicated in 2001, and praised the government for its leadership on the issue,” the U.N. News Centre reports. “Angola provides a large majority of the funding needed to vaccinate the countryâ€™s children,” the news service writes. Ban said the return of polio to Angola within four years after it was eradicated in 2001 illustrated the importance of immunization against polio and other vaccine-preventable diseases, as well as responding to any new polio cases, according to the news service (2/27).
“The number of polio cases worldwide reached a record low in 2012, giving experts confidence that the disease can finally be eradicated, according to presentations made at” the annual meeting of the American Society of Tropical Medicine and Hygiene (ASTMH) in Atlanta on Tuesday, Agence France-Presse reports (11/13). “The number of polio cases around the world that have been reported this year as of October dropped to 177, down from 502 cases as of October 2011,” and “for the first time ever, no new cases were reported in previously unaffected countries, meaning the geographic spread of polio has slowed,” the Los Angeles Times’ “Booster Shots” blog writes (Bardin, 11/13).
The Washington Post reports on polio eradication efforts in Pakistan, writing, “[O]verall trends in Pakistan, where nearly 30 million children have been vaccinated in recent years, are encouraging.” The newspaper writes, “Last year’s cases numbered 198 nationwide,” adding, “This year’s tally is 54.” However, “the intractability of other social ills, including insurgency, poverty, illiteracy and inadequate sanitation, have conspired to ensure that the country remains years away from meeting its goal of polio eradication by the dawn of 2013,” the newspaper notes. The Washington Post discusses a number of challenges to vaccination efforts, such as a Taliban ban on vaccinations and fear among some parents that “the drops contain religiously proscribed (‘non-halal’) ingredients or are part of a Western plot to spread infertility and limit Muslim population growth.” The newspaper adds, “One key to reducing outbreaks, U.N. health workers say, is to educate parents” (Leiby, 11/16).
A “key problem” in reaching the goal of polio elimination “may well be that organizers of the global anti-polio initiative, and of other global health programs, are not listening to the people they want to help — or to each other,” Thomas Abraham, an associate professor in the Journalism and Media Studies Center at the University of Hong Kong, writes in a New York Times opinion piece. “As a result, in many communities targeted by [polio immunization] programs, people perceive a gulf between global programs like polio eradication and more immediate local health needs,” he continues, adding, “It is cold comfort to save a child from polio if the child later succumbs to malaria or diarrhea from dirty drinking water.”
“Afghanistan is taking steps to improve its routine immunization coverage, after a drop in coverage led to a sharp increase in measles outbreaks last year, killing more than 300 children,” IRIN reports. “Experts say nearly 30 percent of the population has no or very poor access to primary health care, including immunization, and the percentage is estimated to be as high as 70 percent in areas of conflict in the south,” the news service writes, adding “decreasing vaccination coverage [is] due to rising insecurity, decreased access, difficult terrain and harsh winters,” as well as last year’s severe drought. “In the National Priority Programmes, which outline government priorities until 2015, the government admits many vaccinators lack initial training, and that budget shortages in past years prevented supervisory and monitoring visits by provincial level management teams,” IRIN states, adding that the WHO this year has implemented training programs and, along with UNICEF and the Ministry of Health, has combined the measles and polio vaccination campaigns to better utilize resources (11/1).
NPR’s “Shots” blog reports on an update about the polio situation in Nigeria, published Thursday in the CDC’s latest issue of Morbidity and Mortality Weekly Report (MMWR), writing, “Despite beefed-up efforts to vaccinate kids and a flood of new resources, … [t]here have been twice as many polio cases as last year, and a few communities, where kids chronically miss vaccines, are serving as ‘sanctuaries’ for the poliovirus, giving it a place to replicate and survive” (Doucleff, 11/8). “Ninety-nine new cases of polio have been reported in Nigeria in 2012 so far — more than in the rest of the world combined, according to the Global Polio Eradication Initiative,” GlobalPost notes, adding, “[W]hile the rest of the world celebrates the near-extinction of the disease, health officials warn the rise of polio in Nigeria this year could lead to a surge in other countries” (Murdock, 11/9). Although “[m]ore kids have been vaccinated this year compared to 2011, and health workers are now using modern satellite tools to track vaccinators and target kids who often get overlooked,” the “Shots” blog notes, “If the virus isn’t stopped in these communities by the middle of next year, the authors [of the MMWR update] call for ‘additional innovative vaccination strategies to interrupt all WPV (Wild Polio Virus) transmission’ in Nigeria” (11/8).
“Polio will never be eradicated in Pakistan until a way is found to persuade poor Pashtuns to embrace the vaccine, according to a study released by the World Health Organization” in its November bulletin, the New York Times reports. A survey of 1,017 parents of young children living in “Karachi, Pakistan’s largest city and the only big city in the world where polio persists, … found that 41 percent had never heard of polio and 11 percent refused to vaccinate their children against it,” according to the newspaper. Some parents from poor families “cited lack of permission from family elders,” Anita Zaidi, a professor at the Aga Khan University in Karachi, said, adding some wealthy parents said the vaccine was “harmful or unnecessary,” the newspaper notes. “Pashtuns account for 75 percent of Pakistan’s polio cases even though they are only 15 percent of the population,” the newspaper adds, noting poorer children are at a higher risk because they are more likely to be exposed to raw sewage, where the virus travels. According to the New York Times, “the eradication drive is recruiting Pashtuns as vaccinators and asking prominent religious leaders from various sects to make videos endorsing the vaccine” (McNeil, 11/5).
Nigeria’s Kano State, Dangote Group, Gates Foundation Sign Memorandum Of Understanding To Fight Polio
Nigeria’s Kano State government, the Dangote Group, and the Bill & Melinda Gates Foundation on Monday signed a multi-year memorandum of understanding “geared towards the eradication of polio in Kano State,” Actualite Afrique reports. According to the news service, a statement from the Gates Foundation said the public-private partnership aims to “improve routine immunization and primary health care in Kano State with a goal of reaching 80 percent coverage with basic vaccines by 2015” (11/27). Under the partnership, the organizations “would provide funding, equipment and technical support to the Kano State government to strengthen polio immunization,” Agence France-Presse writes (11/26).
Global Polio Eradication Initiative IMB Report Optimistic But Warns Of Possible Polio Resurgence In 2013
Though there is “significant risk” of a resurgence of polio in 2013, a new report (.pdf) from the Independent Monitoring Board (IMB) of the Global Polio Eradication Initiative (GPEI) is optimistic about the eradication of the disease, noting that 99.9 percent of polio has been stopped worldwide, with 175 cases reported so far in 2012 compared with 350,000 reported in 1988, BBC News reports. Though the IMB’s “target of stopping global polio transmission by the end of the year will clearly not be achieved,” only four countries — Afghanistan, Nigeria, Pakistan, and Chad â€“ reported cases in 2012 and India was declared polio-free in January, marking a milestone taking it off the list of endemic countries, BBC notes.
