BACKGROUND: Dengue is a significant mosquito-borne disease. Several studies have utilized estimates from the Global Burden of Disease (GBD) study to assess the global, regional, or national burden of dengue over time. However, our recent investigation suggests that GBD's estimates for dengue cases in Taiwan are unrealistically high. The current study extends the scope to compare reported dengue cases with GBD estimates across 30 high-burden countries and territories, aiming to assess the accuracy and interpretability of the GBD's dengue estimates...

The COVID-19 pandemic and subsequent policies (e.g., social distancing, travel restrictions) challenged both organizers for and attendees of programs typically held in-person. Many scientific training programs quickly adapted to virtual formats by incorporating digital assets developed for virtual learning and remote social engagement. At the outset, the value of continuing digital elements with future in-person events was unclear. To examine how virtual resources supported heterogeneous professional training programs, we reviewed survey data for a 14-year-old training program for scientific professionals titled Isotope Tracers in Metabolic Research: Principles and Practice of Kinetic Analysis ...

Travel to academic conferences-where international flights are the norm-is responsible for a sizeable fraction of the greenhouse gas (GHG) emissions associated with academic work. In order to provide a benchmark for comparison with other fields, as well as for future reduction strategies and assessments, we estimate the CO2 -equivalent emissions for conference travel in the field of astronomy for the prepandemic year 2019. The GHG emission of the international astronomical community's 362 conferences and schools in 2019 amounted to 42,500 tCO2 e, assuming a radiative-forcing index factor of 1...

This paper studies a variant of the Pollution Traveling Salesman Problem (PTSP) focused on fuel consumption and pollution emissions (PTSPC). The PTSPC generalizes the well-known Traveling Salesman Problem (TSP), classified as NP-Hard. In the PTSPC, a vehicle must deliver a load to each customer through a Hamiltonian cycle, minimizing an objective function that considers the speed of each edge, the mass of the truck, the mass of the load pending delivery, and the distance traveled. We have proposed a three-phase algorithm for the PTSPC...

UNLABELLED: Banana bract mosaic virus (BBrMV) infection results in characteristic reddish streaks on pseudostem and chlorotic spindle lesions on leaves leading to traveler's palm appearance and complete crop loss depending on the stage of infection in banana plants. Here, we discuss the influence of P. indica colonization (a beneficial fungal root endophyte) on BBrMV infection, specific viral component genes responsible for symptom development, chlorophyll and carotenoid biosynthesis, and degradation in BBrMV-infected banana plants...

Marburg virus disease (MVD) is a dreadful but exceptional disease. Formerly mainly identified in Uganda, Angola and the Democratic Republic of Congo, it has recently appeared in the Republic of Guinea, Ghana, Equatorial Guinea and Tanzania, adding West Africa to the affected regions. Humans become infected through exposure to bats Roussettus aegyptiacus or during unprotected care of infected people. Five cases are linked to travellers, the last one dates to 2008 and involved a visit to caves colonized by bats...

Vaccine could take a central role in the strategy to reduce the burden of dengue. The development of an effective and safe vaccine must address various immunological challenges. Several vaccines are currently in development. To date, two live-attenuated vaccines have been deployed. Both have an effectiveness that varies depending on the serotypes. The deployment of the Dengvaxia vaccine, which began in 2015, was marked by a major safety alert leading to its use being restricted to previously dengue-seropositive people over 9 years old...

A malaria vaccine represents an essential complementary tool to curb the stagnation, or even increase, in malaria cases observed over the last decade due to the emergence of resistance to insecticides impregnated on mosquito nets, wars and internal conflicts, as well as global warming. In October 2021, WHO recommended the use of the RTS,S/ASO1 vaccine for children aged 5-17 months in areas of moderate to high transmission. In October 2023, a second vaccine received WHO approval for deployment in the same population, following demonstration of around 70 % efficacy in protecting young children against malaria for one year...

Multi-resistant Enterobacterales (MRE) are on the increase worldwide, with the main mechanism of resistance acquisition being horizontal transfer of plasmids coding for extended-spectrum betalactamase and/or carbapenemase. Low- and middle-income countries are the most affected, but surveillance in low-endemicity countries, such as Switzerland, is essential. International travel is one of the sources of MRE dissemination in the community, with the main risk factors for acquiring MRE being a stay in South or Southeast Asia and the use of antibiotics during travel...

BACKGROUND: A key aspect of Australia's response to the COVID-19 pandemic was to control transmission through legislated quarantine and isolation of overseas returning travellers and potentially infectious community members. In New South Wales, Special Health Accommodation (SHA) was rapidly established as a comprehensive health service for individuals that were at risk of having COVID-19, were confirmed to have COVID-19 or for those with complex health needs that were deemed inappropriate for management in Police managed Quarantine Hotels...

The region-to-region spread of human infectious diseases is considered to be dependent on the human mobility flow (HMF). However, it has been hard to obtain the evidence for this. Since the onset of the coronavirus disease 2019 (COVID-19) pandemic in Japan 2020, the government has enforced countermeasures against COVID-19 nationwide, namely the restriction of personal travelling, universal masking, and hand hygiene. As a result, the spread of acute respiratory infections had been effectively controlled. However, COVID-19 as well as pediatric respiratory syncytial virus (RSV) infections were not well-controlled...

BACKGROUND: Telemedicine, a method of healthcare service delivery bridging geographic distances between patients and providers, has gained prominence. This modality is particularly advantageous for outpatient consultations, addressing inherent barriers of travel time and cost. OBJECTIVE: We aim to describe economical outcomes towards the implementation of a multidisciplinary telemedicine service in a high-complexity hospital in Latin America, from the perspective of patients...

A previous study demonstrated that rodents on an inclined square platform traveled straight vertically or horizontally and avoided diagonal travel. Through behavior they aligned their head with the horizontal plane, acquiring similar bilateral vestibular cues - a basic requirement for spatial orientation and a salient feature of animals in motion. This behavior had previously been shown to be conspicuous in Tristram's jirds. Here, therefore jirds were challenged by testing their travel behavior on a circular arena inclined at 0°-75°...

BACKGROUND: Japanese encephalitis (JE) is a serious health concern in China, with approximately 80% of global infections occurring in China. To develop effective prevention and control strategies, this study explored the epidemiological characteristics of JE in China based on spatiotemporal data, to understand the patterns and trends of JE incidence in different regions and time periods. METHOD: The incidence and mortality rates of JE were extracted from the Public Health Data Center, the official website of the National Health Commission of the People's Republic of China, and the National Notifiable Infectious Disease Surveillance System from 2004 to 2019...

Recent reports show a rise in instances where municipal networks, such as sewer lines, serve as pathways for vapor intrusion (VI), enabling volatile organic compounds (VOCs) vapors to travel along these networks. These VOCs pose potential health risks to occupants of buildings connected to these networks. Currently, there's a lack of specific technical or regulatory guidance on identifying and assessing the VI risk associated with sewer as preferential VI pathways. This critical review summarizes key findings from studies and site investigations related to sewer VI pathways...

BACKGROUND: High-speed global travel, increased trade, world population growth, migration, urbanisation and climate change have favoured the emergence and spread of pathogens. We aimed to analyse the evolution of imported infections in Spain during 2012-2022 and the potential impact of some of the abovementioned factors on differential morbidity patterns. METHODS: In this retrospective study (January/2012 to December/2022), we analysed data collected by the +Redivi network across 25 health centres...
