ABSTRACTHand hygiene is considered as an efficient and cost-effective way to limit the spread of diseases and, as such, it is recommended by both the World Health Organization (WHO) and the Centres for Disease Control and Prevention (CDC). While the effect of hand washing on individual transmissibility of a disease has been studied through medical and public-health research, its potential as a mitigation strategy against a global pandemic has not been fully explored yet. In this study, we investigate contagion dynamics through the world air transportation network and analyze the impact of hand-hygiene behavioural changes of airport population against the spread of infectious diseases worldwide. Using a granular dataset of the world air transportation traffic, we build a detailed individual mobility model that controls for the correlated and recurrent nature of human travel and the waiting-time distributions of individuals at different locations. We perform a Monte-Carlo simulation study to assess the impact of different hand-washing mitigation strategies at the early stages of a global epidemic. From the simulation results we find that increasing the hand cleanliness homogeneously at all airports in the world can inhibit the impact of a potential pandemic by 24 to 69%. By quantifying and ranking the contribution of the different airports to the mitigation of an epidemic outbreak, we identify ten key airports at the core of a cost-optimal deployment of the hand-washing strategy: increasing the engagement rate at those locations alone could potentially reduce a world pandemic by 8 to 37%. This research provides evidence of the effectiveness of hand hygiene in airports on the global spread of infectious diseases, and has important implications for the way public-health policymakers may design new effective strategies to enhance hand hygiene in airports through behavioral changes.

Abstract   Europe is facing two major structural changes: the climate crisis, having a significant impact on public health, and digitalization of the economy, that could play a role in mitigating climate change and its impacts on public health. The COVID-19 pandemic has affected our lives in many ways including how we see public health, the climate change and has created the conditions for the almost exponential growth for telemedicine and digitalization in healthcare. Underlining that the world is facing an increasing innovation and integration of digital tools to address public health and environmental problems, as the UN Secretary-General and the Director-General of the World Health Organization both declared that we are currently fighting a climate “pandemic” in the same way as we are fighting COVID-19. Digital solutions have been implemented to address COVID-19 and impacted by reducing CO2 emissions and improving quality of life. Digital systems, including Artificial Intelligence, robots and drones, are now changing the paradigm of public health and environment management. Due to the complex nature of the information ecosystem our societies and communities live in, a digital public health approach can be managed to reduce harm to individual, community and population health, support social cohesion and trust in emergency response and interventions to deal with climate change. Digital health could, within 10 years establish a new paradigm in public and environmental health. Public health professionals need urgently to tackle digital health to bridge the gap with others areas of healthcare. During the COVID-19 crisis, national public health authorities have been challenged in the way they communicate with the public, engage with communities in collecting data to improve response, providing the scientific evidence, the day-to-day facts and figures. Likewise, The European Climate Pact provides a space for collectively develop and implement climate solutions. The Climate Pact is an open, inclusive and evolving initiative for climate action through an online platform and citizen dialogues and exchanges, it will foster the link between the digital and green transition. This workshop aims to share the experiences of digital public health interventions with significant impact on climate change mitigation during the pandemic. It will be organised as a round table, starting by setting the scene with an introduction to key digital health concepts and challenges. Each speaker will give a short pitch on how they have experienced the challenge of using digital systems in public health and how they approached its management during the crisis. This will be followed by a panel discussion. Participants will have ample time to ask questions to the panellists. The workshop will end with a summary of a selection of tools participants can use in their own environmental management activities and key take home messages from the panellist will be provided as a conclusion. Key messages Digital Public Health has been establishing evidence on interventions with significant effects on reducing the impact of climate crisis. A Partnership is needed across the health system and society to manage this crisis. European Green Deal and Climate Pact could be used as a roadmap in digital public health.

Abstract Background As the World Health Organization seeks to eliminate trachoma by 2020, countries are beginning to control the transmission of trachomatous inflammation–follicular (TF) and discontinue mass drug administration (MDA) with oral azithromycin. We evaluated the effect of MDA discontinuation on TF1–9 prevalence at the district level. Methods We extracted from the available data districts with an impact survey at the end of their program cycle that initiated discontinuation of MDA (TF1–9 prevalence <5%), followed by a surveillance survey conducted to determine whether TF1–9 prevalence remained below the 5% threshold, warranting discontinuation of MDA. Two independent analyses were performed, 1 regression based and 1 simulation based, that assessed the change in TF1–9 from the impact survey to the surveillance survey. Results Of the 220 districts included, TF1–9 prevalence increased to >5% from impact to surveillance survey in 9% of districts. Regression analysis indicated that impact survey TF1–9 prevalence was a significant predictor of surveillance survey TF1–9 prevalence. The proportion of simulations with >5% TF1–9 prevalence in the surveillance survey was 2%, assuming the survey was conducted 4 years after MDA. Conclusion An increase in TF1–9 prevalence may represent disease resurgence but could also be due to measurement error. Improved diagnostic tests are crucial to elimination of TF1–9 as a public health problem.

Widespread vaccination programmes led to the global eradication of smallpox, which was certified by the World Health Organisation (WHO), and, since 1978, there has been no case of smallpox anywhere in the world. However, the viable variola virus (VARV), the causative agent of smallpox, is still kept in two maximum security laboratories in Russia and the USA. Despite the eradication of the disease smallpox, clandestine stocks of VARV may exist. In a rapidly changing world, the impact of an intentional VARV release in the human population would nowadays result in a public health emergency of global concern: vaccination programmes were abolished, the percentage of immunosuppressed individuals in the human population is higher, and an increased intercontinental air travel allows for the rapid viral spread of diseases around the world. The WHO has authorised the temporary retention of VARV to enable essential research for public health benefit to take place. This work aims to develop diagnostic tests, antiviral drugs, and safer vaccines. Advances in synthetic biology have made it possible to produce infectious poxvirus particles from chemicals in vitro so that it is now possible to reconstruct VARV. The status of smallpox in the post-eradication era is reviewed.

Abstract The Global Mycetoma Working Group (GMWG) was formed in January 2018 in response to the declaration of mycetoma as a neglected tropical disease (NTD) by the World Health Assembly. The aim of the working group is to connect experts and public health practitioners around the world to accelerate mycetoma prevention activities and reduce the impact of mycetoma on patients, healthcare providers and society in the endemic regions. The working group has made tangible contributions to mycetoma programming, awareness and coordination among scientists, clinicians and public health professionals. The group's connectivity has enabled rapid response and review of NTD documents in development, has created a network of public health professionals to provide regional mycetoma expertise and has enabled mycetoma to be represented within broader NTD organizations. The GMWG will continue to serve as a hub for networking and building collaborations for the advancement of mycetoma clinical management and treatment, research and public health programming.

AbstractIn January 2020 China reported to the World Health Organization an outbreak of pneumonia of undetermined origin in the city of Wuhan, Hubei. In January 30, 2020, the World Health Organization declared the outbreak of COVID-19 as a Public Health Emergency of International Interest (PHEI).ObjectivesThe aim of this study is to assess the impact of a COVID-19 epidemic in the metropolitan region of São Paulo, Brazil.MethodsWe used a generalized SEIR (Susceptibles, Exposed, Infectious, Recovered) model, with additional Hospitalized variables (SEIHR model) and age-stratified structure to analyze the expected time evolution during the onset of the epidemic in the metropolitan area of São Paulo. The model allows to determine the evolution of the number of cases, the number of patients admitted to hospitals and deaths caused by COVID-19. In order to investigate the sensibility of our results with respect to parameter estimation errors we performed Monte Carlo analysis with 100 000 simulations by sampling parameter values from an uniform distribution in the confidence interval.ResultsWe estimate 1 368 (IQR: 880, 2 407) cases, 301 (22%) in older people (≥60 years), 81 (50, 143) hospitalizations, and 14 (9, 26) deaths in the first 30 days, and 38 583 (IQR: 16 698, 113, 163) cases, 8 427 (21.8%) in older people (≥60 years), 2181 (914, 6392) hospitalizations, and 397(166, 1205) deaths in the first 60 days.LimitationsWe supposed a constant transmission probability Pc among different age-groups, and that every severe and critic case will be hospitalized, as well as that the detection capacity in all the primary healthcare services does not change during the outbreak.ConclusionSupposing the reported parameters in the literature apply in the city of São Paulo, our study shows that it is expected that the impact of a COVID-19 outbreak will be important, requiring special planning from the authorities. This is the first study for a major metropolitan center in the south hemisphere, and we believe it can provide policy makers with a prognosis of the burden of the pandemic not only in Brazil, but also in other tropical zones, allowing to estimate total cases, hospitalization and deaths, in support to the management of the public health emergence caused by COVID-19.

Introduction: In 1993, the International Task Force for Disease Eradication thought over and concluded that only six diseases are eradicable – but, malaria, dengue fever (and, dengue hemorrhagic fever) were not included. In 2010, 99 countries reported 219 million cases of malaria and 660,000 deaths. In Malaysia in 2011, 5152 cases had been reported causing not more than 30 deaths. Over 2.5 billion are at risk of dengue fever given the endemicity in excess of 100 countries, compared to nine countries in 1970. The WHO estimate 50-100 million cases annually globally, with approximately 500,000 dengue haemorrhagic fever, and an estimated 22,000 death each year. In Malaysia in 2017, there is found 83,849 reported cases of dengue fever with 177 deaths. There is a compelling need to give thought here to an elimination/eradication programme on dengue fever in Malaysia, realizing there is presently a malaria-elimination programme already. Aim: The Aim of this Review is to contemplate on the priority of possible public-health intervention of infectious-diseases, the International Task Force on Disease Eradication, and the three principle/indicators toward successful eradication/elimination programme, and the cost, beside describing the epidemiology and eradication/elimination of malaria in Malaysia, including the human and economic cost of malaria, in a comparison with dengue fever, including the dengue control & prevention programme and the potential in the innovative-methods, and why a dengue fever elimination programme is timely and imperative. Methodology: This article is a Narrative Review, and the author focus the article around three articles published by the author in recent times on dengue fever, and two on malaria. Additionally, the author contemplate around relevant newer article by various author retrieved through PubMed and Google Search. Results: Based on priority of possible public-health intervention of infectious-diseases by the International Task Force on Disease Eradication, and the principle/indicator(s) identified by the Task Force, and the Dahlem Conference, toward successful eradication/elimination programme, and the World Health Assembly on dengue fever, it is felt that a dengue fever elimination programme is timely and imperative, beside found very cost-beneficial. Conclusion: Mankind can eliminate dengue fever, even if not actually eradicating the disease, in a very much feasible and cost-beneficial programme, beginning in every nation and every region of the world, prior to grouping to become a global-programme.

Challenging Situation

Globalisation is a process that integrates the world socio-economic system through trade liberalization, the free movement of people, technologies and information. It has equally made the spread of infectious diseases much easier globally. In essence, infectious diseases such as COVID-19, are easily transmitted across the countries of the world through the network created by globalisation poses serious challenges to the world health system, particularly developing countries like Nigeria. Public health system in Nigeria is overwhelmed by the consequences of the COVID-19 pandemic, which further exposes the country to the adverse effects of globalisation such as dependence and unequal relationship between her and the developed countries. Although the challenging situation provides Nigeria an opportunity to overhaul her public health system, the current poor global economy has further worsened the problems. This paper analyses the situation, and recommends that Nigerian government should look inward to develop her Public health system in a more sustainable way, also, the economy should be repositioned to reduce the level of dependence, and resources should be redirected to adequately fund education and research to support the health sector. The analysis is based on the premises of dependency perspective

Epidemics of smallpox, cholera, plague and other infectious diseases in the world in the past were accompanied by the deaths of millions of people and often threatened humanity with destruction as a biological species. Therefore, society was forced to join forces to create an organization that would provide health protection on a global scale. On April 7, 1948, 26 UN member states created the World Health Organization, the main goal of which was to help provide the protection of health of the population of all countries of the world. Purpose of the study - analysis of the historical data of the process of creating the World Health Organization, achievements for all the years of its existence, financing in last years and formation of the opinions of authors on the role of this organization in solving health problems of all humanity. Results. The article presents data on stages of the formation of the World Health Organization. Information about positive results for more than 70 years in solving reproductive health problems, maternal and child mortality, eradicating many infectious diseases in different parts of the world and other problems is detailed. Joint resolutions of the World Health Organization with the United Nations were adopted about general and complete disarmament, protection of humanity from atomic radiation, ban on the use of chemical and bacteriological weapons, defining of the role of doctors and other health workers in the preservation and strengthening of the world. Information on the World Health Organization funding is provided. The prospects for the development of the organization are described. Conclusions. The World Health Organization actively continues its work – maintains contact with international experts, governments and partners for quick collection of scientific data on a new virus, tracks its distribution and assesses its virulence, provides to countries and population recommendations on health protection measures and preventing the spread of infection. The global climatic crisis and the coronavirus infection pandemic showed that the role of the World Health Organization should increase to prevent cataclysms in some countries and globally. It is the World Health Organization that has a huge positive international experience in fighting various public health problems and it remains the only effective organization that consolidates the efforts of most countries of the world to overcome the problems of all humanity.

BACKGROUND New biomedical prevention interventions make the control or elimination of some blood-borne viruses (BBVs) and sexually transmissible infections (STIs) increasingly feasible. In response, the World Health Organization and governments around the world have established elimination targets and associated timelines. To monitor progress toward such targets, enhanced systems of data collection are required. This paper describes the Australian Collaboration for Coordinated Enhanced Sentinel Surveillance (ACCESS). OBJECTIVE This study aims to establish a national surveillance network designed to monitor public health outcomes and evaluate the impact of strategies aimed at controlling BBVs and STIs. METHODS ACCESS is a sentinel surveillance system comprising health services (sexual health clinics, general practice clinics, drug and alcohol services, community-led testing services, and hospital outpatient clinics) and pathology laboratories in each of Australia’s 8 states and territories. Scoping was undertaken in each jurisdiction to identify sites that provide a significant volume of testing or management of BBVs or STIs or to see populations with particular risks for these infections (“priority populations”). Nationally, we identified 115 health services and 24 pathology laboratories as relevant to BBVs or STIs; purposive sampling was undertaken. As of March 2018, we had recruited 92.0% (104/113) of health services and 71% (17/24) of laboratories among those identified as relevant to ACCESS. ACCESS is based on the regular and automated extraction of deidentified patient data using specialized software called GRHANITE, which creates an anonymous unique identifier from patient details. This identifier allows anonymous linkage between and within participating sites, creating a national cohort to facilitate epidemiological monitoring and the evaluation of clinical and public health interventions. RESULTS Between 2009 and 2017, 1,171,658 individual patients attended a health service participating in ACCESS network comprising 7,992,241 consultations. Regarding those with unique BBV and STI-related health needs, ACCESS captured data on 366,441 young heterosexuals, 96,985 gay and bisexual men, and 21,598 people living with HIV. CONCLUSIONS ACCESS is a unique system with the ability to track efforts to control STIs and BBVs—including through the calculation of powerful epidemiological indicators—by identifying response gaps and facilitating the evaluation of programs and interventions. By anonymously linking patients between and within services and over time, ACCESS has exciting potential as a research and evaluation platform. Establishing a national health surveillance system requires close partnerships across the research, government, community, health, and technology sectors.
