Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically beg...in three to fourteen days after infection. This may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.Recovery generally takes two to seven days. In a small proportion of cases, the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs.
Dengue is spread by several species of mosquito of the Aedes type, principally A. aegypti.The virus has five different types;infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others. Subsequent infection with a different type increases the risk of severe complications. A number of tests are available to confirm the diagnosis including detecting antibodies to the virus or its RNA.

This video animation was created for use in West Africa to help dispel myths about how Ebola is spread, and to prevent infection and further spreading of the disease. The story is based around a teenage boy on a hospital cot in Liberia, who speaks to his parents, brother and sister warning them abou...t the disease and telling them how it can be prevented. The story highlights the need for isolation and shows the heartache of the family as they are unable to comfort, touch, or care for the boy who is very ill. His words are words of comfort to those who are separated from their loved ones as they are encouraged to take care of themselves and keep away from those who are ill.
The video was created by Chocolate Moose Media, an organisation specialising in the use of film and animation for behaviour change, and mobile-health-education innovator iHeed, in collaboration with United Methodist Communications, who provided partial funding.
The video, which uses only young voices, is being made available in eight versions: Nigerian English and Pidgin, South African English, French (for Ivory Coast and Guinea), Sierra Leone English, and Liberian English and Krio. It can be downloaded in high definition, low definition, and for use on mobile platforms.

Terminology used to describe the transmission of pathogens through the air varies across scientific disciplines, organizations and the general public. While this has been the case for decades, during the coronavirus disease (COVID-19) pandemic, the terms ‘airborne’, ‘airborne transmission’ a...nd ‘aerosol transmission’ were used in different ways by stakeholders in different scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations.
This global technical consultation report brings together viewpoints from experts spanning a range of disciplines with the key objective of seeking consensus regarding the terminology used to describe the transmission of pathogens through the air that can potentially cause infection in humans.
This consultation aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities. Despite the complex discussions and challenges, significant progress was made during the consultation process, particularly the consensus on a set of descriptors to describe how pathogens are transmitted through the air and the related modes of transmission. WHO recognizes the important areas where consensus was not achieved and will continue to address these areas in follow-up consultations.

Antimicrobial resistance (AMR) is an increasing worldwide public health problem with
important implications for the European Union (EU). When antibiotics become
ineffective, bacterial infections lead to increased morbidity, use of healthcare,
mortality and cost. Globally, estimates suggest that ...AMR leads to 700 000 deaths
per annum. For the EU, the European Centre for Disease Prevention and Control
(ECDC) has estimated that AMR currently causes 25 000 deaths annually and losses of
at least EUR 1.5 billion per annum in extra healthcare costs and productivity.

Over the past twenty years, huge efforts made by a broad coalition of stakeholders curbed the last epidemic and brought the disease to the brink of elimination. In this paper, the latest figures on disease occurrence, geographical distribution and control activities are presented. Strong evidence in...dicates that the elimination of sleeping sickness ‘as a public health problem’ by 2020 is well within reach. In particular, fewer than one thousand new cases were reported in 2018, and the area where the risk of infection is estimated as moderate, high or very high has shrunk to less than 200,000 km2. More than half of this area is in the Democratic Republic of the Congo. The interruption of transmission of the gambiense form, targeted by the World Health Organization (WHO) for 2030, will require renewed efforts to tackle a range of expected and unexpected challenges. The rhodesiense form of the disease represents a small part of the overall HAT burden. For this form, the problem of under detection is on the rise and, because of an important animal reservoir, the elimination of disease transmission is not envisioned at this stage.

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.

While many of the countries hit by the COVID-19 in the first few months of the year are now beginning to relax lockdown measures as infection and death rates fall, in the regions most affected by HIV, TB and malaria, such as Africa, South Asia and Latin America, the pandemic continues to accelerate.... In lower resource settings, lockdowns are less effective and hard to sustain, and clinical care facilities are extremely limited. In such environments, the response to COVID-19 must focus on containing the pandemic’s spread as far as possible through testing, contact tracing and isolation, protecting the health workforce through training and the provision of personal protective equipment (PPE) and minimizing the knock-on impact on other diseases through shoring up fragile health systems, and adapting existing disease programs.

Against the backdrop of the COVID-19 pandemic, health is receiving unprecedented public and political attention. Yet the fact that climate change also presents us with a health crisis deserves further recognition. From more deaths due to heat stress to increased transmission of infectious diseases, ...climate change affects the social and environmental determinants of health in ways that are profound and far-reaching. The fundamental interdependency of human health and the health of the environment is encapsulated in the concept of planetary health, a scientific field and social movement that has been gaining force since the 2015 publication of the Rockefeller Foundation-Lancet Commission report “Safeguarding human health in the Anthropocene epoch”.
We see an urgent need for strategic communication to raise awareness of climate-health synergies in order to overcome the misperception that climate and health are two independent agendas. The fragmented and sector-focused nature of thinking and action remains a significant barrier to integrating health considerations into climate planning and project development. Inevitably, collaboration across sectors requires a community of practice. Despite recent efforts focused on the climate-health nexus, much work remains to be done to translate scientific findings for policymakers, mobilise climate financing resources in support of health co-benefits, and promote genderjust solutions within climate change projects.

Overwhelming evidence shows that a range of health concerns—mental illness, substance dependence, HIV/AIDS, and noncommunicable diseases—affect prisoners disproportionately. But, while incarceration poses risks to health—including inadequate nutrition and exposure to violence—prisons also pr...esent important opportunities to promote health and risk reduction that need to be tapped.
Some recommended remedies:
Health ministries, not ministries of justice, should manage health care responsibilities
Ensure that testing is available, but not mandatory, for infectious diseases
Make prison health part of the broader public health agenda

Antimicrobial resistance has become one of the most eminent threats to global health and a rising concern for healthcare specialists. All around the world, many common infections are becoming resistant to the antimicrobial medicines used to treat them, resulting in high morbidity and mortality with ...serious social and economic implications. Additionally, there are few new antibiotics being developed but they are expensive and are not new classes. Antimicrobials are critical in the management of infectious diseases. They are also essential tools for protecting animal health and welfare, and contribute in production of safe food. Inappropriate use of antimicrobials can lead to resistance which is known as the antimicrobial resistance (AMR) resulting in high morbidity and mortality with serious social and economic implications.

Antibiotics have been a critical public health tool since the discovery of Penicillin in 1928, saving the lives of millions of people around the world. In developing country like ours, where the burden of treatable disease is very high and access to health facilities and laboratories is difficult, a...ntibiotics have long acted as miracle drugs. Today, however, the emergence of drug
resistance in bacteria is reversing the miracles of the past eighty years, with drug choices for the treatment of many bacterial infections becoming increasingly limited, expensive, and in some cases, nonexistent. Diseases previously regarded as relatively easy to manage are much harder to treat as doctors must use “last-resort” drugs that are more costly, take longer to work
and are often unavailable or unaffordable in developing countries. Moreover, regular prescription of antibiotics, random treatment, over the counter sales, inadequate dosage, inclusion of antibiotics in animal feeds and agriculture has contributed equally to emergence of antibiotics resistance as silent epidemic within the country.

Healthy communities rely on well-functioning ecosystems. They provide clean air, fresh water, medicines and food security. They also limit disease and stabilize the climate. But biodiversity loss is happening at unprecedented rates, impacting human health worldwide, according to a new state of knowl...edge review of the Convention on Biological Diversity (CBD) and WHO.
The report synthesizes the available information on the most important inter-linkages between biodiversity, ecosystem stability, and epidemic infectious diseases such as the Ebola virus; and the connection between biodiversity, nutritional diversity and health. It also covers the potential benefits of closer partnerships between conservation and health, from improved surveillance of infectious diseases in wildlife and human populations, to promoting access to green spaces to promote physical activity and mental health. It also highlights the many areas in which further research is needed.
The Joint report hopes to provide a useful reference for the Sustainable Development Goals and post-2015 development agenda, which represents an unique opportunity to promote integrated approaches to biodiversity and health by highlighting that biodiversity contributes to human well-being, and highlighting that biodiversity needs protection for development to be sustainable.

In the Indian state of Bihar, visceral leishmaniasis (VL) is a major public health issue that has been aggravated by the rising incidence of new Human immunodeficiency virus (HIV) infections. In endemic areas, the risk of VL infections in patients living with HIV (PLHIV) is higher. It is important t...o investigate the disease-related knowledge, attitude, and practices (KAP) of PLHIV in Bihar in order to monitor HIV/VL co-infection. Adequate knowledge, a positive attitude, and good practices for VL control are essential to stamp out the disease. This study investigated the KAP towards VL in HIV patients attending antiretroviral therapy (ART) clinic at ICMR-RMRIMS, Patna.

Cognizant of the need for standardization of the response for COVID-19, the Federal Ministry of Health prepared this national guideline in an effort to contain the epidemic before it overwhelms the health care facilities. This national guideline is expected to guide policy makers and h...ealth professionals at all level. A standardized approaches to will assist effective and efficient utilization of the limited resource of the country, minimizes dilemma and confusion on case management. To this effect, the FMOH has established National COVID-19 advisory committee. The committee members are from different specialties with very good experiences in disaster management and prevention and treatment of infectious disease epidemics. The input from the committee is used to make decisions at the national level about theepidemics in the weeks and months to come. The FMOH would like to acknowledge the members of the national advisory committee for their commitment and unreserved effort in finalizing the task in a very short period of time and advising the Ministry on various issues related to the epidemics at this critical time.

Dengue is the world’s most important arboviral disease in terms of number of people affected. Over the past 50 years, incidence increased 30-fold: there were approximately 390 million infections in 2010. Globalization, trade, travel,... demographic trends, and warming temperatures are associated with the recent spread of the primary vectors Aedes aegypti and Aedes albopictus and of dengue. Overall, models project that new geographic areas along the fringe of current geographic ranges for Aedes will become environmentally suitable for the mosquito’s lifecycle, and for dengue transmission. Many endemic countries where dengue is likely to spread further have underdeveloped health systems, increasing the substantial challenges of disease prevention and control. Control focuses on management of Aedes, although these efforts have typically had limited effectiveness in preventing outbreaks. New prevention and control efforts are needed to counter the potential consequences of climate change on the geographic range and incidence of dengue, including novel methods of vector control and dengue vaccines.

Fully functioning water, sanitation, hygiene (WASH) and health care waste management services are a critical aspect of infection prevention and control (IPC) practices, and ensuring patient safety and quality of care. Such services are also essential for creating an environment that supports the dig...nity and human rights of all care seekers, especially mothers, newborns, children and care providers.
WASH and waste services are also critical for preventing and effectively responding to disease outbreaks. The COVID-19 pandemic has exposed gaps in these basic services (Box 1). These gaps threaten the safety of patients and caregivers, and have environmental consequences, especially as a result of large increases in plastic health care waste. In short, WASH is a critical foundation for improving quality across the health system (1).
Many facilities lack plans and budgets for WASH, which has impacts on IPC. This lack of services, and of systems to improve them, compromises the ability to provide safe and quality care, and places health care providers and those seeking care at substantial risk of infection and loss of dignity. Unhygienic health care facilities without drinking water or functional toilets are also a disincentive to seeking care and undermine staff morale – these factors can have a critical impact on controlling infectious disease outbreaks.
Climate change and its impacts on WASH and health services, gender-specific needs, and equity in service provision and management all require rigorous attention, adaptable tools and regular monitoring.
