Climate change is expected to have complex effects on infectious diseases, causing some to increase, others to decrease, and many to shift their distributions. There have been several important advances in understanding the ...role of climate and climate change on wildlife and human infectious disease dynamics over the past several years. This essay examines 3 major areas of advancement, which include improvements to mechanistic disease models, investigations into the importance of climate variability to disease dynamics, and understanding the consequences of thermal mismatches between host and parasites. Applying the new information derived from these advances to climate–disease models and addressing the pressing knowledge gaps that we identify should improve the capacity to predict how climate change will affect disease risk for both wildlife and humans.

Child marriage and female genital mutilation (FGM) threaten the well-being of millions of girls around the world. Both have existed for generations, as manifestations of gender inequality, and have been propagated by discriminatory norms that devalue girls. In many countries where both child marriag...e and FGM are common, girls most at risk for each practice tend to share certain characteristics, such as low levels of education, rural residence, and living in poorer households. Yet, there are distinct differences in what drives each practice, and many communities in which one may be common, will not practice the other.
This report seeks to identify the extent to which child marriage and FGM co-exist. The intersection of these two practices – that is, the share of women who underwent FGM and were married in childhood – is reviewed over time, to determine whether girls’ likelihood of experiencing both practices has changed across generations. Lastly, the analysis identifies the characteristics that most commonly distinguish the girls who experience one practice from those who experience both.

The main objective of the health systems is to meet the health needs of the population in general, but for this the system must have adequate financing and supply support to cover the entire population in question and check quality, efficiency, equity services, safety and sustainability. However, co...nsidering the segmented Peruvian health system, this makes it more deficient in comprehensive care for the population due to the duplication of functions, misuse of its resources, absence of complementary services. Due to the COVID-19 pandemic, this deficiency in the Peruvian health system became more evident owing to the high number of
deaths and its state of collapse, combining these factors this scope review aims to map the current state of the Peruvian health system, its structure, synthesize data on the performance of the health system (in terms of access, coverage and quality of health services) and identify the main public health policies available

Lymphatic filariasis is a neglected tropical disease that can cause permanent disability through disruption of the lymphatic system. This disease is caused by parasitic filarial worms that are transmitted by mosquitos. Mass drug administration (MDA) of antihelmintics is recommended by WHO to elimina...te lymphatic filariasis as a public health problem. This study aims to produce the first geospatial estimates of the global prevalence of lymphatic filariasis infection over time, to quantify progress towards elimination, and to identify geographical variation in distribution of infection.

The WHO estimates that 19 million children aged 15 years or younger are visually impaired. Of these, 1.4 million are irreversibly blind and need visual rehabilitation interventions for full psychological and personal development. The remainder have visual problems that could be prevented or treated.... Identifying children with visual problems early in life so that they can benefit from medical and optical interventions remains a key challenge for most child eye health programmes. Reports from various low-and middle-income countries indicate that the age of children undergoing operation for cataract is frequently too high to achieve maximum benefit.

Dengue is a significant public health problem. There are four dengue virus serotypes identified; however, its diagnosis is difficult due to the existence of many viruses, bacteria, and parasites producing the same clinical presentation, being presen...t in the same geographical area and even producing coinfections. Therefore, determining whether a person has, had, or is infected with dengue virus is of great importance. In order to do so, direct and indirect laboratory tests have been developed to identify the virus or part of its structure that generally detects the antibody response. These techniques are used for diagnosis, epidemiological studies, monitoring, assessment and production of vaccines and antivirals, etc. They range from the use of cell cultures, animal models, inoculation by insects, and serology tests to the use of detection molecular tests and quantification of genetic material that are described in this chapter herein, a brief explanation of this methodology, its strengths and weaknesses, and its application in the dengue research.

FIND and Standard Diagnostics (SD) have developed a lateral flow rapid diagnostic test (RDT) to screen for
T.b. gambiense HAT that is cheap and easy to use. The tests are packed individually and are stable at 40°C for
up to 25 months; they are performed on fresh blood obtained from a finger prick..., and no instrument or electricity is required. The RDT detects host antibodies to infection in populations that are at risk, or in suspect individuals. Positive cases are subjected to further confirmatory methods to identify HAT patients.

This analysis focused on the chronic form of HAT caused by T. b. gambiense, as it contributes to the majority of disease burden. Information from the literature review,
product development landscape, and stakeholder interviews was compiled to:
- Identif...y use cases and understand current diagnostic practices and tools associated with each use case.
- Analyze progress toward robust diagnostics for HAT across different biomarkers.
- Develop recommendations for steps to improve the availability, access, and adoption of HAT diagnostic tools.

Lymphatic filariasis (LF) is a parasitic disease that is a major cause of chronic disability in the developing world. According to the 2021–2030 road map for neglected tropical diseases (NTDs) published by the World Health Organization (WHO), the global goal for LF is elimination as a public healt...h problem by 2030 through repeated rounds of mass drug administration (MDA). Critical components of any elimination program are monitoring and surveillance. Appropriate assessment tools and methods are needed for each stage of an elimination program; mapping to identify which areas require intervention, monitoring to assess the impact of interventions, and post-intervention surveillance to validate elimination or detect recrudescence.

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.

This report is the annual global monitoring report documenting progress towards Sustainable Development Goal (SDG) 2 targets 2.1 and 2.2. This year’s report explores the links between urbanization and changing food systems and how these changes are impacting the availability, affordability and des...irability of healthy diets, food security and malnutrition in all its forms. It shows that understanding the ways in which urbanization is shaping food systems will require using a rural-urban continuum lens. By mapping the interlinkages across the rural-urban continuum, governments can identify challenges created by urbanization and suitable policies, technologies, investments and governance mechanisms to help address them.

KEY MESSAGES
Always talk to a GBV specialist first to understand what GBV services are available in your area. Some services may take the form of hotlines, a mobile app or other remote support.
Be aware of any other available services in your area. I...dentify services provided by humanitarian partners such as health, psychosocial support, shelter and non-food items. Consider services provided by communities such as mosques/ churches, women’s groups and Disability Service Organizations.
Remember your role. Provide a listening ear, free of judgment. Provide accurate, up-to-date information on available services. Let the survivor make their own choices. Know what you can and cannot manage. Even without a GBV actor in your area, there may be other partners, such as a child protection or mental health specialist, who can support survivors that require additional attention and support. Ask the survivor for permission before connecting them to anyone else. Do not force the survivor if s/he says no.
Do not proactively identify or seek out GBV survivors. Be available in case someone asks for support.
Remember your mandate. All humanitarian practitioners are mandated to provide non-judgmental and non-discriminatory support to people in need regardless of: gender, sexual orientation, gender identity, marital status, disability status, age, ethnicity/tribe/race/religion, who perpetrated/committed violence, and the situation in which violence was committed. Use a survivor-centered approach by practicing:
Respect: all actions you take are guided by respect for the survivor’s choices, wishes, rights and dignity.
Safety: the safety of the survivor is the number one priority.
Confidentiality: people have the right to choose to whom they will or will not tell their story. Maintaining confidentiality means not sharing any information to anyone.
Non-discrimination: providing equal and fair treatment to anyone in need of support.
If health services exist, always provide information on what is available. Share what you know, and most importantly explain what you do not. Let the survivor decide if s/he wants to access them. Receiving quality medical care within 72 hours can prevent transmission of sexually transmitted infections (STIs), and within 120 hours can prevent unwanted pregnancy.
Provide the opportunity for people with disabilities to communicate to you without the presence of their caregiver, if wished and does not endanger or create tension in that relationship.
If a man or boy is raped it does not mean he is gay or bisexual. Gender-based violence is based on power, not someone’s sexuality.
Sexual and gender minorities are often at increased risk of harm and violence due to their sexual orientation and/or gender identity. Actively listen and seek to support all survivors.
Anyone can commit an act of gender-based violence including a spouse, intimate partner, family member, caregiver, in-law, stranger, parent or someone who is exchanging money or goods for a sexual act.
Anyone can be a survivor of gender-based violence – this includes, but isn’t limited to, people who are married, elderly individuals or people who engage in sex work.
Protect the identity and safety of a survivor. Do not write down, take pictures or verbally share any personal/identifying information about a survivor or their experience, including with your supervisor. Put phones and computers away to avoid concern that a survivor’s voice is being recorded.
Personal/identifying information includes the survivor’s name, perpetrator(s) name, date of birth, registration number, home address, work address, location where their children go to school, the exact time and place the incident took place etc.
Share general, non-identifying information
To your team or sector partners in an effort to make your program safer.
To your support network when seeking self-care and encouragement.

Background: The amount of resources, particularly prepaid resources, available for health can affect access to health care and health outcomes. Although health spending tends to increase with economic development, tremendous variation exists among health financing systems. Estimates of future spendi...ng can be beneficial for policy makers and planners, and can identify financing gaps. In this study, we estimate future gross domestic product (GDP), all-sector government spending, and health spending disaggregated by source, and we compare expected future spending to potential future spending. Methods: We extracted GDP, government spending in 184 countries from 1980–2015, and health spend data from 1995–2014. We used a series of ensemble models to estimate future GDP, all-sector government spending, development assistance for health, and government, out-of-pocket, and prepaid private health spending through 2040. We used frontier analyses to identify patterns exhibited by the countries that dedicate the most funding to health, and used these frontiers to estimate potential health spending for each low-income or middle-income country. All estimates are inflation and purchasing power adjusted.
