The World Health Organization (WHO) endorses the use of population-based prevalence surveys for estimating the prevalence of trachoma. In general, the prevalence of TF in children aged 1–9 years and the prevalence of TT in adults aged ≥ 15 years are measured at the same time in any district bein...g surveyed. This was the approach of the Global Trachoma Mapping Project, which undertook baseline surveys in > 1500 districts worldwide in order to provide the data required to start interventions where needed.
The survey design recommended by WHO is a two-stage cluster random sample survey, which uses probability proportional to size sampling to select 20–30 villages, and random, systematic or quasi-random sampling to select 25–30 households in each of those villages. In most surveys, everyone aged ≥ 1 year living in selected households is examined.

This field study to measure access to and use of medicines was undertaken in GHANA in May-June 2008. The study assessed information on the socio-economic level of households, and access to and use of medicines for acute and chronic conditions as well as opinions and perceptio...ns about medicines. The survey was conducted in six regions. In each region, six reference public heath care facilities were selected among those participating in the Level II Facility Survey that was carried out in parallel. Within defined distances from each reference public health care facility, households were selected by purposive cluster sampling. A total of 1065 household respondents were interviewed by means of a structured paper questionnaire

The STEPS survey of noncommunicable disease (NCD) risk factors in Zambia was carried out from July to September 2017. Zambia carried out Step 1, Step 2 and Step 3. Socio demographic and behavioural information was collected in Step 1. Physical measurements such as height, weight and blood pressure w...ere collected in Step 2. Biochemical measurements were collected to assess blood glucose and cholesterol levels in Step 3. The survey was a population-based survey of adults aged 18-69. A multi-stage cluster sample design was used to produce representative data for that age range in Zambia. A total of 4,302 adults participated in the survey. The overall response rate was 74% for Step 1 and 2 and 65% for Step 3. A repeat survey is planned for 2022 if funds permit.

In April and May 2015, Nepal was hit by two major earthquakes killing around 9,000 people and leaving many thousands more injured and homeless.
To optimize the speed and volume of critical humanitarian assistance, the HCT has developed this Plan to:
1. Reach a common understanding of earth...quake risk to ensure early action is taken when required.
2. Establish a minimum level of earthquake preparedness across clusters.
3. Build the basis for a joint HCT response strategy to meet the needs of affected people in the first 6 weeks to 3 months of a response.
4. Define considerations for detailed contingency planning on the basis of the worst-case scenario, especially around access and logistics.

DHS Methodological Report No. 20
This study used Service Provision Assessment (SPA) and Demographic and Health Survey (DHS) data from Haiti, Malawi, and Tanzania to compare traditionally used additive methods with a data reduction method—principal component analysis (PCA).
We scored ...the quality of health facilities with three approaches (simple additive, weighted additive, and PCA) for two constructs: quality of services, with only facilities-level data, and quality of care, which incorporates observation and client data. We ranked facilities as high, medium, or low quality based on their scores. Our results indicated that the rankings change with the scoring methodology. There was more consistency in the rankings of facilities by the simple additive and PCA methods than the weighted additive and PCA-based rankings. This may be due to the low factor loadings and little variance explained by the first component in the PCA. We aggregated facility scores to their respective DHS clusters (Haiti, Malawi) or regions (Tanzania) and geographically linked them to women interviewed in DHS surveys to test associations between the use of family planning services and the quality environment, as measured with each index.

Os sistemas de saúde estão enfrentando um rápido aumento na demanda gerada pelo surto da COVID-19. Quando os sistemas de saúde ficam sobrecarregados, há um aumento drástico na mortalidade direta causada por um surto e também na mortalidade indireta por doenças imunopreveníveis e por aquelas... doenças que possuem tratamento. Análises do surto de ebola em 2014-2015 sugerem que o aumento no número de óbitos causados por sarampo, malária, HIV/AIDS e tuberculose atribuíveis a falhas no sistema de saúde ultrapassou o número de óbitos causados pelo ebola. A capacidade de um sistema de manter a prestação de serviços essenciais de saúde dependerá de sua capacidade inicial e da carga da doença e do contexto de transmissão do vírus COVID-19 (classificado como nenhum caso, transmissão esporádica, em clusters ou comunitária). Manter a confiança da população na capacidade do sistema de saúde de atender, com segurança, as necessidades essenciais e de controlar o risco de infecção nas unidades de saúde é fundamental para garantir que as pessoas continuem a buscar atendimento quando necessário e que sigam as orientações de saúde pública.

In March 2020 the IASC Reference Group on Mental Health and Psychosocial Support uniting 57 humanitarian organizations as member issued the Interim Briefing Note Addressing Mental Health and Psychosocial Aspects of COVID-19 Outbreak. This document has proven to be very useful in the response and has... till now been translated in 24 languages. It covers a set of recommended activities as well as messages for different target groups.
The current document is an annex to the Interim Briefing Note and is meant to support the MHPSS operational response within the various sectors of humanitarian work. Approaches and interventions to MHPSS are not confined to one sector, but need to be integrated within many existing sectors and clusters.This document contains a wealth of operational information and practical approaches that can be used for humanitarian programming in health, SGBV, community-based protection, nutrition, camp management and camp coordination.

Since 2001, several Demographic and Health Surveys (DHS) include HIV
testing. For many countries, in particular in sub-Saharan Africa, DHS are
the only national source of data in general population. Several DHS collect
latitude and longitude of surveyed clusters but the sampling method is not
ap...propriate to derive local estimates: sample size is not large enough for a
direct spatial interpolation.
We developed a generic approach to map spatial regional trends of HIV
prevalence from DHS. We present how our results from Burkina Faso 2003
DHS shed new light on HIV epidemics.

For IST to be effective there is need for utilization of multiple techniques that will lead to transfer of competences (Bluestone et al. 2013). Learning settings should be selected to support relevant and realistic practice so as to increase the efficiency of IST. Alternatives to hotels such as trai...ning institutions and hospitals are viable options for reducing costs of IST as well as being appropriate venues (MOH 2012). There is documented evidence of involvement of academic institutions in providing health leadership capacity building through IST in other countries; for example, in Uganda, IST in leadership for doctors and nurses was done through a blended approach that included didactic and online sessions (Nakanjako et al. 2015). Adapting these concepts, FUNZOKenya piloted eight regional hubs, each serving a cluster of counties, which would train health workers for five years (2012-2016) on priority service delivery topics

Hendra virus (HeV) continues to pose a serious public health concern as spillover events occur sporadically. Terminally ill horses can exhibit a range of clinical signs including frothy nasal discharge, ataxia or forebrain signs. Early signs, if detected, can include depression, inappetence, colic o...r mild respiratory signs. All unvaccinated ill horses in areas where flying foxes exist, may potentially be infected with HeV, posing a significant risk to the veterinary community. Equivac® HeV vaccine has been fully registered in Australia since 2015 (and under an Australian Pesticides and Veterinary Medicines Authority special permit since 2012) for immunization of horses against HeV and is the most effective and direct solution to prevent disease transmission to horses and protect humans. No HeV vaccinated horse has tested positive for HeV infection. There is no registered vaccine to prevent, or therapeutics to treat, HeV infection in humans. Previous equine HeV outbreaks tended to cluster in winter overlapping with the foaling season (August to December), when veterinarians and horse owners have frequent close contact with horses and their bodily fluids, increasing the chance of zoonotic disease transmission. The most southerly case was detected in 2019 in the Upper Hunter region in New South Wales, which is Australia's Thoroughbred horse breeding capital. Future spillover events are predicted to move further south and inland in Queensland and New South Wales, aligning with the moving distribution of the main reservoir hosts. Here we (1) review HeV epidemiology and climate change predicted infection dynamics, (2) present a biosecurity protocol for veterinary clinics and hospitals to adopt, and (3) describe diagnostic tests currently available and those under development. Major knowledge and research gaps have been identified, including evaluation of vaccine efficacy in foals to assess current vaccination protocol recommendations.

Monkeypox virus is an orthopoxvirus that causes human monkeypox, a viral disease with symptoms similar to smallpox, including fever and rash. Following the worldwide eradication of smallpox in 1980, monkeypox emerged as the most significant orthopoxvirus infection in humans. Cases are most often rep...orted from rural areas of Central and West African countries, particularly in regions close to tropical rainforest where people may have contact with infected animals. Someone can become infected through direct contact with respiratory droplets of another person who has monkeypox in the home or in a health facility, or with contaminated materials such as bedding. Although these are the main modes of person-to-person transmission, monkeypox outbreaks tend to occur in small clusters of a few cases without leading to widespread community transmission. For this reason, outbreaks can be easily controlled when responded to rapidly. On several occasions, monkeypox has been reported in other regions due to importation by travelers or infected animals. This course provides a general introduction to the disease through a video and accompanying downloadable presentation that can be reviewed at your own pace. It is intended for health personnel responsible for prevention and control of monkeypox, and for the general public.
The content and scope of this course on monkeypox have been tailored for outbreaks in African countries where the disease is endemic. The course material was last updated in 2020 and may not reflect most recent WHO guidance issued for the multi-country outbreak in 2022.

Background: The human helminth infections include ascariasis, trichuriasis, hookworm infections, schistosomiasis, lymphatic filariasis (LF) and onchocerciasis. It is estimated that almost 2 billion people worldwide are infected with helminths. Whilst the WHO treatment guidelines for helminth infecti...ons are mostly aimed at controlling morbidity, there has been a recent shift with some countries moving towards goals of disease elimination through mass drug administration, especially for LF and onchocerciasis. However, as prevalence is driven lower, treating entire populations may no longer be the most efficient or cost-effective strategy. Instead, it may be beneficial to identify individuals or demographic groups who are persistently infected, often termed as being “predisposed” to infection, and target treatment at them.
Methods: The authors searched Embase, MEDLINE, Global Health, and Web of Science for all English language, humanbased papers investigating predisposition to helminth infections published up to October 31st, 2017. The varying definitions used to describe predisposition, and the statistical tests used to determine its presence, are summarised. Evidence for predisposition is presented, stratified by helminth species, and risk factors for predisposition to infection are identified and discussed.
Results: In total, 43 papers were identified, summarising results from 34 different studies in 23 countries. Consistent evidence of predisposition to infection with certain species of human helminth was identified. Children were regularly found to experience greater predisposition to Ascaris lumbricoides, Schistosoma mansoni and S. haematobium than adults. Females were found to be more predisposed to A. lumbricoides infection than were males. Household clustering of infection was identified for A. lumbricoides, T. trichiura and S. japonicum. Ascaris lumbricoides and T. trichiura also showed evidence of familial predisposition. Whilst strong evidence for predisposition to hookworm infection was identified, findings with regards to which groups were affected were considerably more varied than for other helminth species.
Conclusion: This review has found consistent evidence of predisposition to heavy (and light) infection for certain human helminth species. However, further research is needed to identify reasons for the reported differences between demographic groups. Molecular epidemiological methods associated with whole genome sequencing to determine ‘who infects whom’ may shed more light on the factors generating predisposition.
