Polio Highlight

Update on the polio situation in China

One new case was reported in the past week, bringing the total number of cases for 2011 to 18 (all WPV1). The most recent case had onset of paralysis on 18 September (from Kashgar, in Xinjiang Uygur autonomous region). Following three SNIDs conducted in September and October (targeting varying age groups), an additional campaign is planned for 12-16 November, using domestically-produced monovalent OPV type 1. Depending on the area, the age range of the activity will cover persons aged 0-39 years.

World Polio Day: 24 October

It is World Polio Day on 24 October. Rotary International is asking all those who support global polio eradication to visit to join the likes of Bishop Desmund Tutu, Queen Noor of Jordan, Bollywood legend Amitabh Bachchan and action star Jackie Chan to create their own personal 'This Close' poster. Supporters are encouraged to use this poster as their Facebook profile picture for World Polio Day.

Update – China Polio Outbreak

  • No cases were reported in the past week, leaving the country's total case count at ten. All cases were reported in Xinjiang Uygur autonomous region - nine in Hotan prefecture and one in Bazhou prefecture. The most recent case had onset of paralysis on 5 September in Bazhou.
  • In districts surrounding Hotan prefecture, 4.5 million teenagers and adults aged between 15 and 39 years of age were vaccinated with trivalent OPV from 23-27 September. This older-age round is in response to several recent cases among people in their twenties. A vaccination round targeting children up to the age of fifteen will begin on 8 October.

Grand Challenges in Immunization Systems

Dear Colleagues,

As we move to introduce a growing number of vaccines in low and middle income countries, we need to ensure that the systems trusted with delivering them are ready for the task.

Over the past year a group of partners and stakeholders has been working to develop a vision for immunization supply systems for 2020.

A key part of this work was a landscape analysis of efforts ongoing to strengthen immunization logistics and supply systems, and an assessment of the gaps that need to be addressed to move from the efforts underway to achieving this vision.

A first step in finding innovative solutions for some of these gaps has been launched by the Gates Foundation's Grand Challenges Explorations program, offering grants of $100,000 to promising 2 page proposals that address a selection of the gaps.

This year, the initiative offers scientists, inventors, non-governmental organizations, ministries of health and entrepreneurs from around the world the opportunity to acquire US$100 000 grants to pursue unconventional ideas that could transform immunization supply systems in low and middle income countries.

Proposals are being sought in the following priority areas:

  1. Vaccine characteristic prioritization;
  2. Immunization supply system design;
  3. Environmental impact;
  4. Information systems;
  5. Human resources; and
  6. Vaccination acceptance.

Projects showing success will have the opportunity to receive additional funding up to US$1 million.

Some clarifications regarding poliovirus circulation in the Americas

  1. There is no circulation of wild polioviruses in any country of the Americas;
  2. The last wild poliovirus that was isolated in the American Region was in Peru in 1991;
  3. In April 2011, Peru reported a paralytic polio case caused by a Sabin-derived virus;
  4. Active search, specimens collected, and vaccination campaigns in the community were conducted in response to this case;
  5. No evidence of circulation of that virus was found;

PAHO restates its recommendations on strengthening the Acute Flaccid Paralysis (AFP) surveillance system and the evaluation of its indicators at national and sub-national level, and on the identification of high-risk districts and on the appropriate measures to protect the community. The risk of reintroduction of wild polioviruses to the countries of the American Region remains high as long as there is circulation of wild viruses in the world. Just last month the virus was reintroduced into China from Pakistan.
