          New polio cases reported in the past week for 2011: 16
          Total number of cases in 2011: 536
          Total number of cases in 2010: 1352
 
     1.    Headlines
 
   -    In response to the Independent Monitoring Board report which states that 'the programme is not on track for its end-2012 goal, or for any time soon after unless fundamental problems are tackled', partners in the Global Polio Eradication Initiative are building an emergency programme of work, to be put in place by January next year. The work streams for the change process include management and accountability, tracking and monitoring plans, systematic innovation, surge support in outbreak settings and deeper stakeholder engagement.
 
   -    Oral polio vaccine (OPV) will continue to be administered during measles campaigns in 2012, and may also be given during current and planned campaigns in west and central Africa using the new conjugate meningococcal A vaccine. Aside from the obvious efficiencies this creates, it promotes closer cooperation between staff working on polio eradication as well as accelerated measles and meningitis control, allowing for further commonalities to be recognized. So, for instance, measles case data could be used to predict polio outbreaks (because they act as a marker of low routine immunization).

     2. Endemic countries 

          Afghanistan
 
     -    Two cases were reported in the past week, both wild poliovirus type 1 (WPV1), bringing the total number of cases for 2011 to 55. The most recent case was reported with onset of paralysis on 22 October (in Maywand district, Kandahar province). Afghanistan now has the highest number of infected provinces for a single year in more than ten years.
 
     -    Two Short Interval Additional Dose (SIAD) rounds will be held on 27-29 November and 4-6 December. These rounds will aim to rapidly build immunity in 28 districts of Southern Region and 5 districts in the country's west. The second SIAD round is part of larger Sub-national Immunization Days (SNIDs) which will cover the south, south-east and east of the country.
 
     -    The focus right now is to improve the quality of supplementary immunization activities (SIAs) in Farah, with the team leader currently in Herat to discuss appropriate measures.
 
     -    The country's most recent supplementary immunization activities (SIAs ) were National Immunization Days (NIDs) using bivalent oral polio vaccine (bOPV) on 24-26 October.
 
     -    On 22 November, a meeting took place in Kabul on polio eradication, routine immunization and the role of Basic Package of Health Services (BPHS) Non-governmental Organizations (NGOs). A key outcome was that 'permanent OPV teams' will start work in high-risk districts of Southern Region by the end of the year, going from house-to-house on a permanent basis.
 
          India
 
     -    India continues its streak without wild poliovirus - having not reported a case in more than ten months. The country's only case for the year was reported in West Bengal on 13 January.
 
     -    Keeping up immunity and sensitive surveillance in India will be the top priority in the coming months. SNIDs began on 13 November in parts of Uttar Pradesh, Bihar, West Bengal and other high-risk areas. The most recent SIAs were SNIDs held from 25 September.
 
          Nigeria
 
     -    Two cases were reported this week, both in Kano state. The total number of cases for 2011 is now 44. The most recent case had onset of paralysis on 15 October, in Kumbotso district. The other case reported this week was in Gaya district - a district which had not previously reported a case of WPV this year.
 
     -    Immunization Plus Day (IPDs) have just been completed in 12 high-risk districts, following the Maternal and Newborn Child Health Week (MNCHW) held last week. During the MNCHW, which ran from 14-19 November, infants under the age of one in the southern half of the country were offered trivalent oral polio vaccine (tOPV). The IPDs, which began on 20 November, covered the rest of the country, aiming to vaccinate more than 15 million children under five with tOPV.
 
          Pakistan
 
     -    Pakistan continues to report a high number of cases, officially reporting nine more this week (all WPV1s). The total number of cases for 2011 is now 154; the most recent of which had onset of paralysis on 1 November in North Waziristan district in the Federally Administered Tribal Areas (FATA).
 
     -    Aside from reporting high numbers of WPV cases, environmental sampling continues to test positive to WPV1 at every single sampling site across the country (seven in Punjab, six in Sindh, two in Khyber Pakhtunkhwa and two in Balochistan). The only positive indication from environmental sampling is that wild poliovirus type 3 (WPV3) has not been isolated in over a year.
 
     -    SNIDs wound up yesterday in some of the highest risk districts. The round aimed to vaccinate 4.8 million children under five in three districts of Punjab, five districts of northern Sindh and one district of FATA, along with high-risk union councils (UCs) in 12 districts of Khyber Pakhtunkhwa (KP ). A Short Interval Additional Dose (SIAD) round will follow the SNIDs in Bajour (in FATA), Swabi (in KP) and several districts of northern Sindh. Punjab is using its own funds to finance 'enhanced outreach' to cover mobile and migrant populations.
 
     -    Prime Minister Yousaf Raza Gilani will preside over the meeting of the National Polio Task Force taking place on November 24. A renewed version of the National Emergency Acton Plan for polio eradication (NEAP) will be presented to the Task Force for their review. It is hoped that this meeting will help to 'reboot' Pakistan's polio eradication programme.
 
     -    Of the more than 300 WHO polio worker positions to be filled in high-risk sub-district areas in Pakistan, appropriate candidates have been found for 67% of the planned positions. Every position in Sindh and Karachi has been filled, and 97% of the positions in Balochistan have been filled. On the other hand, only 9% of the 88 positions in FATA have been filled. How ever, many of the positions in FATA will be filled from the more than 50 existing staff members. CVs have been collected, and a review is currently being conducted.

     3. Importation countries 

          Angola
 
     -    No new cases were reported in the past week. The total number of cases for 2011 remains five. The most recent case had onset of paralysis on 7 July (WPV1 from Uige).
 
     -    SNIDs, using monovalent oral polio vaccine type 1 (mOPV1), are scheduled for 25-27 November in Luanda, Lunda Norte, Lunda Sul, Cabinda, Zaire, Uige, Cuando Cabango and northern Malange, covering most of the north and the southwest of the country and vaccinating more than 3 million children under five. Similar SNIDs were conducted in late October, covering the same districts except for Cuando Cabango.
 
     -    A further round of SNIDs is currently being considered for early December, to increase immunity in Uige. The site of the country's most recent case, Uige is close to the border with the Democratic Republic of the Congo, and the case is closely linked to the Democratic Republic of the Congo's Bas Congo/Bandundu transmission chain. Technical support is being scaled up to Uige, to assist effo rts to prevent further spread across the border.
 
          Chad and central Africa
 
     -    Two cases were reported in Chad in the past week (both WPV1s). The total number of cases for 2011 has risen to 119 (116 WPV1s and three WPV3s). The most recent case had onset of paralysis on 14 October in N'Djamena Sud, a district of N'Djamena. Both the cases reported this week were in districts which had not previously reported a case this year (the other case was from Ati district in Batha province).
 
     -    Chad's most recent SIAs were NIDs using bOPV from 28 October. Further NIDs, again using bOPV, will take place from 25-27 November.
 
          -  While monitoring data from Chad's last round showed it to be less-than-perfect, with seven districts rejected at 90% coverage, such data provides the kind of sharp focus that is crucial. This shows that the recent scale-up of technical support is already beginning to have an impact. This can also be seen in the fact that improved microplanning is being used to plan the upcoming vaccination round.
 
     -    Representatives of WHO, UNICEF, CDC and the Bill & Melinda Gates Foundation visited Chad last week to lend their technical expertise to the process of reviewing the country's emergency action plan. Dr Robert Scott, the chair of Rotary's International PolioPlus Committee, will visit Chad in the coming weeks.
 
     -    No new cases were reported from the Central African Republic (CAR) in the past week. The total number of cases for 2011 remains two (both WPV1s), the most recent of which had onset of paralysis on 6 October in Region Sanitaire 3 (RS3), in the country's north. CAR will hold NIDs using bOPV from 25 November (synchronised with Chad). In RS3, children up to the age of 15 will be targeted, in the rest of the country the round will target the usual age-range - children under five. A SIAD round will be held in December in RS3, again vaccinating children under 15 years of age.
 
     -    A case of WPV3 reported just inside Cameroon's border has been found to have been a Nigerian child who contracted the virus in Nigeria, just across the border in Borno state. As such, it looks highly likely that the case will be reassigned to Nigeria. Despite this, Cameroon has decided to maintain its current SIA schedule, acting as a further barrier to the virus' spread. The country's next round will be SNIDs using bOPV in the three northern-most regions.
 
          China
 
     -    No new cases were reported in the past week - the total number of cases for 2011 therefore remains 18 (all WPV1). The most recent case had onset of paralysis on 18 September (from Kashgar, in Xinjiang Uygur autonomous region).
 
     -    SNIDs took place last week (12-16 November). Monovalent OPV1 was used to vaccinate people up to 39 years of age in five prefectures around the outbreak, while children up to five years of age received the vaccine in the rest of Xianjiang Uygur Autonomous Region.
 
          Democratic Republic of the Congo
 
     -    One new case was reported in the past week. The total number of cases for 2011 is now 87 (all WPV1s). The most recent case had onset of paralysis on 29 September (from the outbreak district of Popokabaka in Bandundu).
 
     -    SNIDs took place in high-risk areas of Bandundu, Bas-Congo, Katanga, Maniema and Sud Kivu from 10-12 November. Further SNIDs will take place in these same districts from 10-12 December, aiming to reach more than 1.3 million children under the age of five years with an additional dose of bOPV. On 13 December, tOPV will be given alongside measles vaccine in Nord Kivu, Kinshasa and the districts of Bas Congo and Bandundu that weren't covered in the SNIDs.
 
          Horn of Africa
 
     -    There were no cases reported in the Horn of Africa this week. There has only been one case reported in the Horn of Africa this year - a WPV1 with onset of paralysis on 30 July in Nyanza Province, on Lake Victoria in western Kenya.
 
     -    SNIDs on 12-16 November covered much of Kenya with bOPV, including districts surrounding this year's case. A further round is planned for 3-7 December. Reports from those who witnessed Kenya's recent round are 'guardedly optimistic'.
 
     -    Uganda recently held SNIDs in areas bordering Kenya on 19-21 November, targeting more than 700,000 children under the age of five years with mOPV1. Two SIAD campaigns in 22 districts along the border with the Democratic Republic of the Congo will be held on 3-5 December (using bOPV) and on 17-19 December (using tOPV), each time targeting more than 2.1 million children under the age of five.
 
     -    Child Health Days (CHDs) were held in Tanzania from 12-15 November. The round targeted nearly 7 million children in districts near to the case in Kenya with measles vaccine and bOPV.
 
     -    Technical staff from India's National Polio Surveillance Project (NPSP) stationed in Kenya have extended their stay. This will allow them to continue to provide expert guidance on Kenya's polio eradication and surveillance strategies, and to help in the preparations for Kenya's December round.
 
     -    For the first time in almost two years, Banadir and Mogadishu in Somalia have been able to be covered more than once with polio vaccine. Given the increased access, NIDs using tOPV are planned for 4-8 December. Wherever children are accessible, they will be vaccinated against polio.
 
          West Africa
 
     -    No cases were reported in west Africa in the past week. The total number of cases for 2011 in the west African region remains 48 (36 from Côte d'Ivoire, three from Guinea, seven from Mali and two from Niger). All cases are WPV3, except for one WPV1 case from Niger.
 
     -    Much of the west African importation belt took part in the multi-country round which took place on 28 October. Togo postponed participation in the multi-country round, instead vaccinating children under five using tOPV on 11 November. A smaller multi-country round has been planned for 25 November, covering all of Mali and Côte d'Ivoire along with parts of Guinea, Liberia and Niger.

           The National Institute of Hygiene and Epidemiology in Hanoi and the Pasteur Institute of Ho Chi Minh City are the two national public health reference laboratories in Vietnam. They operate as referral centres for 63 provincial public health laboratories which together form a national communicable disease surveillance network. Peter McMinn has worked with both major laboratories over the past five years, to strengthen their capacity to provide leadership in national communicable disease surveillance. Vietnam is now one of a handful of countries in Asia Pacific, and the only developing country, with internationally accredited public health laboratories.

          Vietnam is a developing country with a population of nearly 90 million people that suffer from a large burden of communicable disease. The World Health Organization has recommended that member nations should maintain functional laboratory surveillance systems to define disease burdens and trends, to identify epidemics and to monitor the effectiveness of public health interventions such as immunsation. The need for Vietnam to conduct pandemic surveillance has been highlighted by its central role in the SARS and avian influenza epidemics of the past decade.

              At the commencement of the project, both the National Institute of Hygiene and Epidemiology in Hanoi and Pasteur Institute in Ho Chi Minh City supported a small number of highly functioning laboratories that generated excellent surveillance data. A feature common to these laboratories was that they received external funding from WHO and the Global Fund, and were linked to international research and surveillance networks. Most of the laboratories, however, were poorly funded, received very few specimens for testing, experienced low staff morale and provided a poor quality of service. Further, senior management was not providing the leadership required to deliver the change necessary to improve their institute’s quality of service.

          Thus the aim of the project was to embed international best practice in laboratory quality management at the two institutes. The primary goal has been to assist the institutes and laboratories achieve accreditation against the International Standards Organization standard for medical laboratory quality systems - ISO15189: 2007 Medical Laboratories - Particular Requirements for Quality and Competence. The project has received strong support from the Vietnamese Ministry of Health and the WHO, and has been funded by WHO and the Australian Government.


          The first phase of the project involved the formation of
writing groups comprising people from the University of Sydney, and senior staff from the laboratories in Ho Chi Minh and Hanoi. The groups met frequently to oversee the complex task of the drafting institute-specific quality manuals and associated documentation in both English and Vietnamese. Preparation of documents was central to the success of the project, so a 9-12 month period was set aside to ensure that the final documents met the needs of both institutes and were also compliant with ISO15189. It was also necessary to ensure that the Vietnamese translations accurately reflected the meaning of technical documents initially drafted in English. This required translators who were fluent in both English and Vietnamese, and also trained and experienced medical laboratory scientists who understood the concepts outlined in the documents and possessed the required technical vocabulary in both languages. Needless to say, people with such a mix of skills are very rare!
 

The National Institute of Hygiene and Epidemiology, Hanoi.

          During the period of document drafting, the Sydney team also developed a number of training courses and programs, including training-of-trainer programs in quality management, and training courses in quality auditing, equipment calibration and method validation. These focused on the technical and managerial requirements of ISO15189. Two adult educators from Learning Solutions at the University of Sydney were recruited to the project in order to ensure that best practice adult learning techniques were applied. The completed training course notes and presentations were then translated into Vietnamese.

          Training of trainers in quality management was undertaken in Hanoi and Ho Chi Minh City in 2009-10. In December 2010, the first group of quality management trainers from laboratories in 20 southern provinces were trained at Pasteur Institute. Collectively, trainers from the two major institutes have trained more than 250 laboratory staff in the principles and practice of quality management in 15 separate courses. The first provincial laboratory Quality Management training course was held at My Tho, Tien Giang Province, in February 2011, with trainers from Pasteur and laboratories collaborating in the delivery of this course. It was very gratifying to observe the realisation of our goal of sustainability in quality management training in Vietnam.

QUALITY MANAGEMENT

          Auditing is an essential aspect of laboratory quality management. It is necessary to audit each component of the quality system at least once per year to ensure its integrity and to identify and correct non-conformances. Audit training was provided at Pasteur in Ho Chi Minh in July 2010 and at National Institute of Hygiene and Epidemiology in Hanoi, and in the southern city of Can Tho in April 2011, resulting in a total of 68 trained ISO1589 auditors to date. Upon completion of training, the new auditors wasted no time in commencing audits of their quality system in preparation for ISO15189 accreditation. Training of trainers modules are being developed for the quality audit training course and training is planned for November 2011, which will further embed the sustainability of quality management training in Vietnamese public health laboratories.

          Another essential requirement of laboratory quality management is enrolment in an external quality assurance program, in which the laboratory receives blinded specimens and is required to examine them and identify the unknown pathogen and/or cause of disease. These programs provide a rigorous test of the integrity of the quality system and participation is an essential prerequisite for ISO15189 accreditation. Currently, there is no external quality assurance program available in Vietnam. The National Institute in Hanoi has been directed by the Ministry of Health to develop a national quality assurance program over the next three years, but in order to ensure that the two reference laboratories comply with international quality standards in the short-term, the project has funded the provision of the Royal College of Pathologists of Australasia external quality assurance program to both institutes for a period of two years. This will be reviewed in 2013 and the need for an extension addressed.

          The introduction and maintenance of laboratory quality management is a complex task requiring good leadership, communication and teamwork. Much of the  workload is carried by designated institutional “Quality Managers,” whose task it is to ensure laboratory and institutional compliance with the quality system and to prepare their institute for accreditation. In order to assist the National Institute of Hygiene and Epidemiology and Pasteur Institute in Ho Chi Minh City in this difficult role, a study tour of several large Australian hospital and public health laboratories was arranged in November 2010. Tour participants were given privileged access to a large amount of confidential information and documentation on how several leading Australian clinical and public health laboratories manage their quality systems and prepare for ISO15189 accreditation. They were also able to network with Australian quality managers which has provided an excellent source of advice and support in preparing for their own accreditation inspections.

          In conclusion, the quality management capacity building project has been well received throughout the public health laboratory system in Vietnam, with 12 leading laboratories in Hanoi, Ho Chi Minh and in Tien Giang Province, achieving ISO15189 accreditation to date. Numbers are growing, with 13 more planning accreditation inspections in the coming 12 months. Other than Vietnam, the only countries in the Asia–Pacific region to have ISO15189-accredited public health laboratories are Australia, New Zealand, Japan, Singapore, Korea and Hong Kong. This is a major achievement for a developing country and has placed Vietnam in a unique position to serve as a regional leader in the global surveillance of epidemic and pandemic disease.

          23 MARCH 2012 - From 1 January to 11 March (epidemiologic week 10), outbreaks of meningococcal disease has been reported in 15 districts in Benin, Burkina Faso, Chad, Côte d'Ivoire and Ghana (see table below1).
 
          These outbreaks have been detected as part of the enhanced surveillance in the African Meningitis Belt conducted in 14 countries2 where a total of 6 685 suspected meningitis cases including 639 deaths have been reported.

          The outbreaks are mainly caused by the W135 serogroup of Neisseria meningitidis(Nm) bacteria. In Chad, the predominant pathogen is Nm A, although NmW135 contributed to an outbreak in one district. Whereas NmA has always been the leading cause of epidemics in sub-Saharan Africa, outbreaks of NmW135 have already occurred in the region, since 2002.

          The countries are responding to these outbreaks by enhancing surveillance, reinforcing treatment of patients and implementing mass vaccination campaigns. The International Coordinating Group (ICG) on Vaccine Provision for Epidemic Meningitis Control has approved the release of 117'500 doses of polysaccharide ACW vaccine to Côte d'Ivoire, 195'540 doses of polysaccharide ACYW vaccine to Ghana and 359'000 doses of conjugate Men A vaccine to Chad, along with injection materials and ceftriaxone (antibiotic) when necessary. The ICG constitutes of United Nations Children's Fund (UNICEF), Médecins Sans Frontières (MSF), International Federation of Red Cross and Red Crescent Societies (IFRC) and WHO.

          WHO continues to monitor the epidemiological situation closely, in collaboration with partners and Ministry of Health in the affected countries.

          The supply of the appropriate vaccine to respond to W135 outbreaks is presently limited, and WHO and UNICEF are working closely with the vaccine manufacturers to ensure that this stock is maintained and adapted to the evolving outbreak situation.

          Travelers are reminded of the importance of keeping their vaccination status up to date and to follow WHO travel advice. WHO emphasizes that individuals planning to travel to countries in the African Meningitis Belt obtain vaccine to protect against the four serogroups responsible for the epidemic disease (tetravalent vaccine ACYW135).
