WORLD HEALTH ORGANIZATION WHO Angola Update May 2001 Epidemic surveillance resources of this global campaign – radios, cold chain, staff and so on – can be leveraged to improve the whole system. Additional monies have been given by Sweden, Holland and Portugal. WHO’s coordinators are also charged with working to involving all possible partners surveillance and response activities, says Dr Rui. “An NGO working in agriculture might still be able to help us by transporting stool samples, or providing a radio link for epidemic surveillance to an area we otherwise might not be able to reach.” New focus in the provinces After two years with little presence in the provinces WHO in coordination with the Ministry of Health has re-established its support to local health authorities with the opening of seven epidemiological ‘antennae’. Key aims of these posts are to be a “catalyst” for provincial structure, inject new life into epidemic surveillance activities, co-ordinate polio eradication activities and boost routine immunisation to 75 per cent coverage for all vaccine-preventable diseases by the end of 2001 – an ambitious target in a country where rates have plummeted to 30-45 per cent in recent years. Five antennae – in the provincial capitals of Uige, Benguela, Lubango and Moxico, plus Luanda – have been launched so far, and two more, in Huambo and Cabinda, are due to open by the end of May. All bar Lubango are staffed by an international public health doctor. “We have purposely created these WHO antennae inside the provincial health delegation instead of stand-alone offices because the aim is to help build a team that can continue the work when our expatriate co-ordinator leaves,“ says Dr Rui Gama Vaz, WHO team chief for the Expanded Programme of Immunisation (EPI) and polio eradication, who has been developing the project in close collaboration with the director of national public health Dr Adelaide de Carvalho. “The antenna is an engine to motivate local staff to do active surveillance,” he adds. A network of newly recruited WHO national staff, one for each of the other provinces, will also be linked to the antennae, a staff expansion which it’s hoped will overcome on-going problems with motivation among local technical staff at field level. Antenna staff will track, investigate and facilitate quick response to six key epidemic diseases – measles, meningitis, cholera, antenatal tetanus and yellow fever – as well as coordinating acute flaccid paralysis surveillance and polio campaigns. The offices are funded by the polio campaign (see page 5) – an example of how the Emergency response Floods, displaced and resettlement Rapid assessment missions are taking place every week in Angola for different reasons: some are to newly accessible zones or areas planned for resettlement, while others are in response to urgent changing circumstances. Led by the Ministry of Social Assistance and Reinsertion (MINARS) and OCHA , the missions include UN agencies, NGOs and members of the Government emergency teams. WHO takes part whenever it has capacity to do so and is hoping to fund and recruit a further international staff member to increase its participation. The Angolan Government and OCHA have identified some 71 newly accessible areas in need of assessment this year. More than 20 security and needs assessments had been carried out by early May Mission reports are available from OCHA Angola, ucah@compuserve.com Maternal health Study to trace crucial elements of care In-depth operational research into the care and services available to women from the time they become pregnant through delivery and postnatal care is due to start in the next few months. Funded and supported by WHO, the research will be done by the Ministry of Health under the leadership of Dr Adelaide de Carvalho, director of national public health. It will provide essential information on which to base action to reduce 1 May 2001 WORLD HEALTH ORGANIZATION what is estimated to be one of the highest rates of maternal mortality in the world. “It has been very difficult to get information about the very high maternal mortality rate. Even what we have is an estimate since it is based on information from health institutions when almost 85% of women give birth without an assistance,“ says Ms Dalva Barros, WHO’s national officer for reproductive health. “We know it is tied up with destruction of health infrastructure, movement of people, lack of appropriate supplies and equipment and the level and motivation of staff, but what we want to do is pin down clear areas where we can intervene and establish clear practical actions.” It is anticipated the study will also reveal specific in-service training needs. Currently there is no formal system of continuing education in Angola and most of those who attend women prenatally or in delivery are technicians with no specialist training. Huambo, Bengo, Moxico and Malanje are the sites selected for the research, and preparatory discussions are currently taking place with the local authorities. The project will also link with the Swedish-funded CAOL (Coordenação Atendimentio Obstetrico de Luanda) project which is focusing more on institutional services, and with work being done by UNICEF involving maternal death audit “We need to have a system which investigates each maternal death – particularly in the community – to find out causes are responsible,” says Dr Pier Paolo Balladelli, WHO representative for Angola. “It means tracing the management of women, looking for problems and gaps and then, very importantly, looking for solutions and implementing them. In individual units or in the community, immediately changing some apparently small factors can sometimes have crucial impact on the big issue – the death of women in childbirth.” By way of example Dr Oscar Castillo, medical co-ordinator for UNICEF says an analysis of 56 maternal deaths in Huila showed the clinical causes of death to be malaria (50%), haemorrhage (20%), infection (20%), obstruction (15%) and toxaemia (15%). But in 65% of these cases greater use and availability of antenatal services, more rapid referral to hospital and better management and treatment once there could have saved lives. In principle, adds Dr Castillo, “all maternal deaths are preventable”. safe delivery methods, referral systems, family planning and sexual health care. The agency is focussing at two levels. In IDP camps, it works with local health authorities and with partner NGOs to train health workers and activists to promote activities known to impact on maternal mortality,. It also provides displaced women with female ‘hygiene’ kits including soap, sanitary towels and males and female condoms. Outside the camps, it and its partners are trying to strengthen health structures though rehabilitation, training and provision of drugs and equipment. Reproductive health National plan to guide activities Running parallel to operational research described above, the Ministry of Health supported by WHO is currently discussing with partners the development of a national plan of action for reproductive health to guide interventions from state and non-governmental organizations over the coming years. In recent years, co-ordination of activities in the field have been ad hoc at best. “Having a national plan will make it easier for the Ministry of Health to coordinate all the groups who are currently intervening in reproductive health to obtain the most effective outcomes for the country,” says Ms Dalva Barros, adding that information from NGO partners will be crucial in preparing the document. WHO, UNFPA and UNICEF are working with the Ministry of Health on the plan which they hope will be finalised by the end of 2001. Obstetric update reaches out WHO and the Ministry of Health have carried out the first of what is hoped will be a series of updating courses for obstetric technicians and traditional birth attendants (TBAs) working in institutions and the community throughout the country, complementing work also being carried out by UNFPA. Funded by WHO, Ministry of Health trainers have trained maternity nurses working in Cabinda, Bengo, Kwanza Nord, Kwanza Sud, Huambo, Moxico, Kunene and Namibe, and TBAs in Malanje, Kwanza Sul and Cuando Cubango. WHO has also donated funds to the School of Midwifery in Luanda and a school in Huila which is piloting a new approach to training technicians in health. Though various international NGOs have been providing training in maternal and reproductive health in their particular areas of operation, it is many years since there has been systematic updating of obstetric workers, who play a vital Practical work on minimum package The United Nations Population Fund is working to help Ministry of Health facilities develop a minimum package for reproductive health care for women, including pre- and post-natal care, 2 May 2001 WORLD HEALTH ORGANIZATION role in a country which has a critical shortage of medical doctors. Further training for TBAs is being discussed, but is dependent on accessing new funds. For its part UNFPA is particularly concerned to ensure that TBAs receive good supervision and regular supplies to enable them to raise their standards and keep them up. as the pilot sites to introduce the programme and are now discussing with local authorities exactly which health facilities will take part. However, the programme badly needs further funding if it is to have a real impact on child health. It is estimated that some $500,000 is needed to carrying out training, and a further $2m to rehabilitate infrastructure and provide materials and drugs in just five provinces Addressing the sensitive subject “It’s not easy to talk about contraception in situations where treatment for simple conditions may be limited,” says Dr Julio Leite da Costa, UNFPA assistant representative. “However in surveys and when we are distributing kits, we find an increasing demand for condoms and other family planning methods.” UNFPA distributes female hygiene kits in displaced camps as well as supplying contraceptives and treatment for sexually transmitted diseases to health facilities, and carrying out training in reproductive and sexual health counselling. Malaria control Major donor to Roll Back Malaria WHO is currently working with the US Agency for International Development on what is hoped will be a US$5m donation to fight malaria in Angola. The funds, channelled through WHO, will boost the National Malaria Programme of the Ministry of Health and used to introduce and implement the global Roll Back Malaria Initiative which combines strategies of prevention, education, access to treatment and environmental control of the mosquito. Exxon Mobil has also committed to assist the Ministry of Health in the programme, which is led in Angola by MoH national programme director, Dr Filomeno Fortes. Angola suffers from more than 1 million cases of malaria a year. It prompts 50% of consultations and causes 40% of maternal mortality. With many other African nations last year, Angola signed up to the Initiative that seeks to reduce malaria incidence by half by the year 2010. Several studies are already under way to lay foundation for the initiative. Research into drug resistance is about to start in Luanda and Huila provinces, and an expert team from the WHO African Regional Office, has been in Angola recently investigating the use of impregnated bed nets. After investigation missions to Huambo, Lobito and Funda, the team has recommended the Government investigate the possibility of removing import tariffs from nets and distributing free nets to the poor and displaced. It also urged rapid development of community treatment centres – a project now being implemented by UNICEF (see next column) – and the inclusion of impregnated nets in emergency non-food item kits. It’s understood that the Government has committed to buying 200,000 impregnated nets for this purpose. Child health New push on childhood diseases WHO and UNICEF are keen to help the Ministry of Health get the global programme of Integrated Management of Childhood Illness (IMCI) back on track in Angola this year. Though the strategy was officially accepted in 1997, intervening events left it on the back burner. Now, the drive is on to implement the programme that focuses on good management of the five key causes of infant death – malaria, diarrhoea, pneumonia, malnutrition and measles. The work, together with efforts to reduce maternal death, is receiving crucial backing from Angola’s Vice Minister of Health Dr José Vieira Dias Van Dúnem. Guided by Angolan expert Dr Luis Bernardino, director of Luanda’s Paediatric Hospital, WHO’s child health officer and a team of five Angolan paediatricians who attended IMCI training in Brazil are currently adapting the global programme to reflect Angolan needs and develop training materials – work funded by the Italian Government. Dr Bernardino says another key partner in the development work is the CAPEL (Coordenação Atendimentio Paediatrico de Luanda) group of units in Luanda, which have been putting into practice a simplified version of IMCI, thanks to support initially from the Swedish International Development Agency and now WHO and Coorporazione Italiana. In the meantime, the Ministry of Health has identified the provinces of Benguela and Huila First strike against malarial environments A pilot project based on the principles of the Roll Back Malaria programme is due to start in Huila province shortly. 3 May 2001 WORLD HEALTH ORGANIZATION Organised by the Ministry of Health and supported by WHO, the project brings together elements of environmental health and prevention. A provincial group is to train health technicians and community activists to practically assess the malarial situation of the as-yet-to-be defined site and then implement strategies to reduce standing water, control water sources, improve sanitation and deliver mosquito nets to an population. Lessons learned from this project will be applied in a second pilot in Kwanza Sul with the ultimate intention of rolling out the work throughout the country. donors and people with sexually transmitted infections. The first studies are already running. – one exploring the prevalence and knowledge, attitudes and practices of 500 TB patients in Luanda, the other exploring the same factors in 500 pregnant women in Luanda, Benguela and Huila. Results should be ready next month. Another study, planned for Viana displacement camp just outside Luanda, will be particularly valuable, says new WHO HIV/AIDS project manager Dr Alberto Stella, because the area has people from all over the country. Very little concrete information is available about the extent of HIV/AIDS in Angola. WHO/UNAIDS have estimated that just under 44,000 Angolans are currently HIV positive. But in August 2000, fewer than 6,300 cases had been reported at national level and most estimates are extrapolated from small studies. Prevalence is thought to be substantially higher in northern provinces than the southern. Figures from 1999 suggest that prevalence in TB patients in Cabinda is double that in similar patients in Luanda (34% versus 19%) and three times higher in pregnant women (8% versus 3.4%). “The most important thing at the moment is to strengthen national surveillance and understand behaviour. It is vital that we know what is really happening with HIV/AIDS in this country. Only then can we start to develop the programmes to control the disease,” says Dr Stella. The aim is to get HIV/AIDS data into the national information system so that data can guide the selection of new strategies and interventions to combat the epidemic can be monitored. Other activities include developing national guidelines on HIV surveillance, improving clinical management and setting up a voluntary counselling and testing centres (see below). WHO and the Ministry of Health hope also to secure links with other health-related organizations. Centres expand net of prevention UNICEF’s project for community-based mosquito net impregnation centres has reached four provinces. Three centres are now open in Luanda, six in Benguela, two in Uige and one in Bengo. The centres impregnate new nets with insecticide and sell them at a very reduced price ($2-3), and provide training and materials for ‘dip-it-yourself’ treatment. Dr Oscar Castillo says the demand for impregnated nets has far surpassed expectations “even in Uige where people are very poor”. Some 7000 nets were distributed in the first month of centre operations. But he cautions that nets have a good market value and a second stage of the project includes the development of malaria education centres and health activist who can visit and evaluate the use of the nets. HIV/AIDS Study seeks clarity on HIV rate A US$500,000 project to provide baseline data critical to guide the fight against HIV/AIDS in Angola began last month and will produce its first results in June. Funded by the Italian Government, the study is part of 18-month Angolan Initiative for the Fight Against AIDS in Africa and is a collaboration between the Angolan National Institute of Public Health, provincial health authorities and WHO. It involves developing health system capacity to collect and analyse information on HIV prevalence and population behaviour, operational research, the introduction of voluntary testing and counselling, and strengthening laboratory testing. Six sentinel sites, five in the provinces (Cabinda, Moxico, Lunda Sul, Lubango, Benguela and Malanje) and one in Luanda, have been set up and staff are being trained in cross-sectional and behavioural research in four important indicative groups: TB patients, pregnant women, blood Testing and counselling is first step Developing the capacity to treatment of sexually transmitted infections will be a key entry point for HIV detection and counselling and is another element of the WHO/Cooperazione Italiana AIDS initiative, according to project manager Dr Alberto Stella. “The rate of syphilis and gonorrhoea in normal Angolan is frightening. But the national health service needs to be strengthened to treat these conditions, when they are diagnosed. Improving capacity to test, diagnose and manage STIs will also allow us to strengthen diagnostic services for HIV/AIDS.” 4 May 2001 WORLD HEALTH ORGANIZATION Priority activities planned over the next year are translating guidelines manuals for STI and voluntary testing and counselling services, training in clinical management, creating laboratory capacity and carry out research into the feasibility of a programme against mother to child transmission. A pilot voluntary testing and counselling service is currently being set up in a TB clinic in Luanda which treats over 20% of the capital’s TB patients, and a second has been opened by international NGO Goal. WHO also hopes to work with the Angolan Association of People Living with HIV/AIDS to find ways of linking testing and counselling to existing antenatal, TB and STI clinics. NIDs synchronise to find hidden infants Logistics, cold chain and social marketing teams are also moving into high gear to prepare for this national immunisation days (NIDs) which, it is hoped, will be coordinated across a whole swathe of Central Africa including Gabon, Democratic Republic of Congo, Republic of Congo and Angola. Cross border vaccination is also being discussed with Zambia and Namibia. For Angola, synchronisation raises the hope that at least some children in inaccessible border areas might be able to receive vaccine from cross border teams if no other way is possible. Though His Excellency President Dos Santos recently committed himself to the principle of polio vaccine for all children under five wherever they live in Angola, finding the way to put this desire in action is more difficult The Ministry has real concerns about the areas which cannot at present be accessed either for vaccination or AFP surveillance, since without information from these areas, it will not be possible to certify Angola polio-free. In 1999 Angola suffered a massive polio outbreak with 1117 cases and 113 deaths. Last year, there were 55 cases, but so far in 2001 there have been no confirmed cases though at the time of writing 14 are still under investigation. Polio eradication Team plans to map every child By the end of June, the location of every house, tent or shack containing a child under five in the accessible areas of Angola, should be on a map, somewhere, somehow. This is the goal of joint Ministry of Health, WHO and UNICEF polio eradication team who believe ‘micro-planning’ will lift the number of children vaccinated in this year’s national immunisation days to as close to 100 per cent of those reachable as possible. Last year, 4 million under-fives – just over 80 per cent of those living in Government-controlled areas – got their pink drops in three rounds of immunisation days. But this left almost a million unvaccinated children to add to the 2 million left out because they lived in inaccessible municipalities inaccessible. If you don’t have good enough micro-planning, everything else falls down,” notes Dr Rui Gama Vaz, WHO polio team leader. This year the Ministry of Health and WHO want to have a really good quality, house to house intervention. To do this the number of people dedicated to polio has already expanded by 100 people whose task is to map at municipal level, as well as investigate any report of the acute flaccid paralysis that can be a marker of a polio case. A further 100 being recruited. The Global Polio Eradication Initiative in Angola is coordinated by the Ministry of Health under the leadership of Dr Fátima Valente, director for the Expanded Programme of Immunization, and supported by the campaign’s long-term partners, Rotary International, USAID, the US Centers for Disease Control and CORE, plus new partners including the UK Department for International Development (DfID), the Netherlands and several private companies. STOP teams are go Two, two-person volunteer ‘STOP’ teams (Stop Transmission of Polio) will arrive this month from the US Centers for Disease Control and Prevention to support the Ministry of Health in mission to improve acute flaccid paralysis surveillance and help with in preparations for July’s national immunisation days. Tuberculosis How to get DOTS back on track? The Ministry of Health, supported by WHO, is this year trying to rejuvenate a TB programme that has been fighting a losing battle over recent years due to an environment that is almost the completely opposite of conditions needed for effective treatment. TB is the second most important cause of mortality in Angola. Over 15,000 cases were reported in 1999, a figure thought to be well surpassed in 2001, but at present treatment is available for around 1500 patients. DOTS (Directly Observed Treatment Short-course) was introduced in 1998 but is achieving cure rates of less than 40 per cent where it has been implemented. “It is very hard to imagine that many of the centres which should, and would like, to implement DOTS have been able to do it until 5 May 2001 WORLD HEALTH ORGANIZATION now because of the difficulty of following Health information patients and maintaining good supplies of drugs,” says WHO officer Dr Sebastian Nkunku. While population movement is one challenge, maintaining free drug supply is another major problem to be overcome. In Cuito Hospital, the sanatorium manager says patients receive free drugs, but low supplies leave dozens waiting for treatment. Lack of streptomycin this month, he adds, has prevented between 15 and 25 children from starting treatment. Database clears blockage A new database holds the promise of better health information for all partners in health in future. Working with the National Institute of Public Health, WHO staff are gradually putting in place a new information system that it’s hoped will streamline not only collection but also feedback to the units which provide the data. In 2000, over half Angola’s municipalities filed information and it is hoped that, with widespread training and the increasing ability to provide quick feedback on data to provincial level, this will improve further, says WHO epidemiologist Dr Etelvina Correia, “With the new database we will be able to analyse the information much more quickly and respond to problems.” Part of the new approach is a monthly health bulletin and a system of radio-based reporting for epidemic disease. The project is currently funded by WHO Angola from emergency donations. Trypanosomiasis Active campaign needed to stop epidemic In the early 70’s, like most of the affected countries of Africa, Angola had almost completely controlled sleeping sickness. In 1973 only 3 cases were reported. Now, says Professor Teófilo Josenando, director of the Ministry of Health’s Institute for the Combat and Control of Trypanosomiasis, more than 25% of the population is at risk of the disease and between 80,000 and 120,000 currently have it. Among the key reasons for this is the break down to the active surveillance and investigation systems due to the turmoil of war, mass population displacement and the inability of health workers to access large numbers of the rural population. The Institute, together with WHO, is working hard to re-instate systems of active surveillance and investigation in affected areas, says Prof. Josenando. Projects are particularly focused on setting up the systematic screening systems crucial to catching people while they are still in the first phase of the disease, establishing mobile laboratory and treatment clinics, and trying to discover shorter-term, more effective ways to use the heavy-duty second phase drugs. In this last area, Angola with WHO support is taking part in a seven-country research project. “It’s very important to implement programmes that are tailored to local conditions and staff,” says WHO’s officer responsible for trypanosomiasis, Dr Sebastian Nkunku. “At the moment in Angola, we have many more people who have reached the second phase of sleeping sickness which is much more grave. The only drugs for the second phase are very strong and can cause complications. If we can re-establish an active campaign which can reach the people, test them for the disease early, and start treatment, it will make a big difference.” Environmental Health School latrines are first step to health “It’s hard to train children and teachers about hygienic environments if they don’t have the basics facilities to put your advice into practice,” says Inga Gabriela Guerra, WHO’s national officer for water and sanitation. Hence WHO’s project to build latrines and water reservoirs for eight schools in the Luanda province. Twenty latrines in five schools have already been built in the US$40,000 project which is a small part of the Initiative Africa 2000 which focuses on environmental health. WHO is also supporting the Ministries of Health and of Energy and Water to establish latrine-building groups initially in Namibe, Kwanza Sul and Kwanza Nord. Under the initiative, week-long technical seminars were held last year in 14 of Angola’s 18 provinces, covering subjects such as protection of water sources and catchment areas, good treatment practice, preventing water-related disease, environmental hygiene and even how to build effective latrines. The remainder planned for this year. Emergency chlorine distributed Fifty kilogramme barrels of chlorine went out to all Luanda’s municipalities this month to counteract poor water quality caused by floods and unscrupulous water sellers. Supplied by UNICEF, the chemical was distributed by WHO which also supported the Ministry of Health in training health workers to 6 May 2001 WORLD HEALTH ORGANIZATION prepare solutions for the public consumption, after a study showed quality of water in Luanda was decreasing.

WHO Representative Dr Pier Paolo Balladelli Administration Mr Michel Kouakou EPI and Polio Eradication Dr Rui Gama Vaz, , Poverty alleviation Emergency and Humanitarian Action Dr Domingos Nsala Focus on health in new strategy Health is a key element in the reduction of poverty according to the Government of Angola proposals for the Interim Poverty Reduction Strategy proposal to be presented to the Bretton Woods Institutions. In its first draft, priorities such as the reduction of infant and maternal mortality, prevention of HIV/AIDS and control of communicable diseases such as tuberculosis and leprosy were strongly represented, and indeed health goals took up half of the documents proposal section. The UN team including WHO, UNICEF and UNFPA has supported the Government’s emphasis on the social sectors, particularly with regard to HIV/AIDS saying there is a synergistic relationship between conflict, poverty and the disease. ”Mounting an effective national response to HIV/AIDS clearly must be a centre part of the poverty reduction strategy from the interim phase onwards,” noted the agencies in a memorandum presented to the Government on May 2. The Ministry of Planning is organising a seminar at the end of June with the assistance of the World Bank, the International Monetary Fund and the United Nations to conduct consultations on the social sector strategies outlined in the Interim Poverty Reduction Strategy Paper.
