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.
Equitable health services
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.
The Zimbabwe government and the United Nations Children’s Fund (UNICEF) conducted a countrywide immunisation programme aimed at eliminating polio and other diseases to prevent children from having the same experience as Chirewa and others. It is a continuation of similar efforts over the past few years. The programme has seen many mothers across the country taking their children to centres around the country for immunisation. About two million children were vaccinated during the week-long programme, not only immunised against polio but also against diseases such as tuberculosis, measles, diphtheria, tetanus, whooping cough and hepatitis B. They also received vitamin A supplements.
Zimbabwe's deteriorating health services have made room for a thriving parallel market for drugs, many of them counterfeit, warn concerned health professionals. The sale of genuine as well as fake medicines on the streets was "big, booming business," said Dr Paul Chimedza, the president of the Zimbabwe Medical Association (ZIMA). "The health system has been adversely affected by the poorly performing economy. There is a general shortage of drugs within the country and unscrupulous dealers are capitalising on the situation by selling medical drugs on the streets."
This study explores caretakers' experiences of care-seeking for childhood febrile illness with fatal outcome in rural Uganda to elucidate the most influential barriers to adequate care. A mixed methods approach using structured Verbal/Social autopsy interviews and case narratives was employed with 26 caretakers living in the Iganga/Mayuge Demographic Surveillance Site who had lost a child 1–59 months old due to acute febrile illness between March and June 2006. The main barriers to care were misdiagnosis by the caregiver, gender and household financial constraints, and dissatisfaction with providers, reflecting inadequate levels of service. Poverty was identified as the underlying theme. Any improvements in basic health care for children suffering from acute febrile illness are likely to substantially reduce mortality.
