The University of the Witwatersrand in South Africa has announced the formation of the Wits Research Institute for Malaria, (WRIM), strengthening research into one of Africa’s deadliest diseases. The Institute combines three existing research groups from the School of Public Health who are working on malaria vectors, parasites and pharmacology. Africa has very few research institutes that have the capacity to address a host of issues and make an impact on the disease. The WRIM aims to produce leading research and researchers to benefit malaria control in Africa.
Equitable health services
In the run-up to International Women's Day, 8 March, the International Committee of the Red Cross (ICRC) warned that the specific health-care needs of women are often ignored or insufficiently taken into account in war situations. ‘People wounded in fighting are given priority for medical treatment, but women, even pregnant mothers, are often given scant attention despite their special needs,’ said the ICRC's adviser on issues relating to women and war. In the world’s least developed countries, many of which are at war, women are 300 times more likely to die in childbirth or from pregnancy-related complications than in developed countries, according to UNICEF. In war time, women are particularly at risk of rape and other forms of sexual violence and they have no means of transportation to reach a health-care facility so as to give birth safely.
Despite lack of resources, activities undertaken to mitigate the impact of neglected tropical diseases are so far producing unprecedented results, according to this report. It points to a number of successes: treatment with preventive chemotherapy reached 670 million people in 2008, while dracunculiasis, also called guinea worm disease, is on course to becoming first disease eradicated not by a vaccine, but by health education and behaviour change. Reported cases of sleeping sickness have also dropped to their lowest level in 50 years. The report notes opportunities for strengthening delivery systems, such as by targeting primary schools to treat millions of children for schistosomiasis and helminthiasis in Africa. In addition, better co-ordination is argued to be needed, such as with veterinary public health and to respond to changing disease patterns resulting from climate change and environmental factors.
Responsibility to take forward a still in-progress framework to cope with global influenza pandemics is now in the hands of the World Health Organization Director General Margaret Chan. The framework is intended to set forth guidelines for the sharing of viruses, vaccines, and other benefits related to pandemic strains of influenza. This includes mechanisms for tracing and reporting outbreaks, as well as for capacity building, technology transfer, and stockpiles of vaccines. It also includes a model binding contract for entities sharing viruses with pandemic potential.
This video from WHO introduces the concept of people-centred care. Globally, one in 20 people still lack access to essential health services that could be delivered at a local clinic instead of a hospital. And where services are accessible, they are often fragmented and of poor quality. WHO is supporting countries to progress towards universal health coverage by designing health systems around the needs of people instead of diseases and health institutions, so that everyone gets the right care, at the right time, in the right place.
This report released by the World Health Organisation (WHO) reveals that a third of 306 anti-malarial medicines collected and tested from six African countries failed to meet international quality standards. Reasons for this failure include insufficient active pharmaceutical ingredient (API), an excess of degradation substances, and poor dissolution. In fact in two samples one of the APIs was totally absent. The countries surveyed were Cameroon, Ethiopia, Ghana, Kenya, Nigeria and Tanzania. The quality of anti-malarial medicines varied across countries, from Ethiopia – where no samples failed quality testing – to Nigeria, where the highest incidence of failure occurred (64%). This result implies that a patient in Nigeria is more likely to be treated with a substandard anti-malarial than a patient in a country that complies with international quality standards. Failure rates were noticeably low for WHO-prequalified medicines available in these countries (less than 4%) as well as for imported products manufactured by well-established manufacturers. The report concludes that WHO prequalification is a highly effective mechanism for verifying the quality of medicines.
This paper reports on yellow fever vaccination coverage following massive emergency immunisation campaigns in the Pader district, northern Uganda, in 2010. A total of 680 respondents were included in the sample and vaccination status was assessed in a survey using self reports and vaccination card evidence. Of the 680 respondents, 654 (96.3%) reported being vaccinated during the last campaign but only 353 (51.6%) had valid yellow fever vaccination cards. Of the 280 children below five years of age, 96.1% were vaccinated. The main reasons for not being vaccinated were: having travelled out of Pader district during the campaign period (40%), lack of transport to immunisation posts (28%) and sickness at the time of vaccination (16%). These results show that actual yellow fever vaccination coverage was high and met the desired minimum threshold coverage of 80% designated by the World Health Organisation. Active surveillance is necessary for early detection of yellow fever cases.
The authors note the emerging epidemic of yellow fever in Angola and spread of similar Aedes aegypti mosquito-borne viruses including dengue, chikungunya, and now Zika, albeit with differences noted. Yellow fever was first identified as a viral infection in 1900, has been reported from more than 57 countries and yellow fever outbreaks have case fatality rates as high as 75% in hospitalised cases. There has been an effective yellow fever vaccine since the late 1930s, but with outbreaks in unvaccinated populations in 1987 in urban Nigeria, despite a mass vaccination campaign. According to WHO, the current yellow fever outbreak is in more than six of Angola's 18 provinces, and there has been movement of unvaccinated travellers from Angola to neighbouring Democratic Republic of the Congo, but also to further states, including Mauritania, and China. Southeast Asian countries are now considered at risk because the Aedes vector is present and the population is unvaccinated. However should yellow fever outbreaks occur elsewhere in Africa, in Latin America, or in Asia, the authors note that the current global supplies of yellow fever vaccine may be inadequate.
Cholera outbreaks in Tanzania's semi-autonomous island of Zanzibar have continued due to poor hygiene standards, health officials said on Wednesday, while announcing renewed efforts to raise public awareness. "We need to double our efforts of awareness; we also need to strengthen by-laws to make sure that the islands are kept clean," Dr Omar Suleiman, an officer in the Ministry of Health, said in Stone Town, capital of Zanzibar.
Zimbabwe’s overall health service has been steadily declining for the last five years. The Zimbabwean health service today is wracked by critical shortages of essential drugs and skilled and experienced personnel. Another challenge is there has been no comprehensive assessment of Zimbabwe’s health system since 2006, making it difficult to assess its true state. Also, its disease surveillance and early warning system, which depends on a weekly epidemiological system, has been compromised in terms of timeliness and completeness of data, which is only around 30%. Universal access to basic health services is compromised due to deteriorating infrastructure, staffing and financial resources. Reactivating primary health care services should keep being addressed as a matter of emergency. Zimbabwean health facilities face a massive gap – estimated this year at 70% – in required medicines due to reduced local manufacturing capacity, which has been weakened by a lack of foreign currency. This is despite support received from different partners through UNICEF’s procurement systems. A large cholera outbreak is affecting most regions of the country, with more than 11 700 cases and 473 deaths recorded between August and 30 November. This represents a case fatality rate (CFR) of 4.0% nationally, but reached 50% in some areas during the early stages of the outbreak. The CFR benchmark should be below 1%. Cholera outbreaks in Zimbabwe have occurred annually since 1998, but previous epidemics never reached today’s proportions. The last large outbreak was in 1992 with 3000 cases recorded. Cholera cases have also been reported either side of Zimbabwe’s border with South Africa, Botswana and Mozambique, demonstrating the subregional extent of the outbreak.
