Background
Dengue and malaria remain critical vector-borne threats in Latin America, yet mortality surveillance at subnational levels is sparse. Ecuador, a country with diverse ecological zones and shifting transmission dynamics, lacks standardized hospital-based mortality indicators to guide targeted interventions.
Objective
To analyze age-standardized hospital mortality rates for dengue and malaria across Ecuador's 24 provinces from 2015 to 2023, identifying geographic disparities, temporal trends, and surveillance gaps.
Methods
We conducted a cross-sectional ecological study using anonymized hospital discharge data from the National Institute of Statistics and Censuses (INEC). Fatal dengue and malaria cases were identified using ICD-10 codes and stratified by year, age groups, and province. Standardized mortality rates per million inhabitants were calculated using population projections, and geographic and temporal patterns were visualized through heat maps and time-series plots.
Results
Dengue accounted for 125 hospital deaths, with mortality concentrated in Amazonian and coastal provinces. Malaria, though markedly less frequent, resulted in five adult deaths (3 in 2019, 1 in 2021, and 1 in 2023), with Plasmodium falciparum predominating. The highest malaria mortality rate occurred in Napo (16.3 per million in 2021), underscoring the fragility of elimination gains. Both diseases revealed fragmented mortality patterns, with isolated spikes and persistent underreporting in endemic zones.
Conclusion
Hospital-based mortality data expose critical gaps in Ecuador's arboviral and Plasmodium spp surveillance. While dengue shows episodic lethality across endemic provinces, malaria's sporadic fatality signals in urban, non-endemic regions highlight the need for sustained clinical vigilance and integrated mortality monitoring.

In April 2023, outbreaks of a novel oral disease were observed in Bactrian camels in Altay Prefecture, Xinjiang, China. To clarify the etiology and epidemiology, we surveyed 1863 camels from 12 farms across three major camel-producing counties. A total of 311 camels (16.7 %) exhibited characteristic lesions, with significantly higher incidence in adults (18.1 %) than juveniles (9.7 %) (p < 0.05). Tissue samples from 12 clinically affected camels were subjected to PCR testing for multiple poxviruses. Only Camel Contagious Ecthyma Virus (CCEV) was detected, and sequencing of the B2L gene confirmed its identity. Phylogenetic analysis revealed that Xinjiang isolates shared >98 % nucleotide homology with strains from Saudi Arabia and Sudan, with no variation among the 12 local sequences. Histopathology showed epidermal necrosis, hyperplasia, and intracytoplasmic inclusion bodies, consistent with parapoxvirus infection, and electron microscopy revealed typical poxvirus morphology. These findings document the first confirmed detection and molecular characterization of CCEV in camels in China, highlighting its potential impact on the camel industry and the need for further investigation of its epidemiology and zoonotic risk.

Dengue virus (DENV), a globally prevalent flavivirus, is a growing threat in regions where HIV is endemic. The co-endemicity of HIV and dengue poses overlapping clinical challenges, particularly in low-resource settings where diagnostic capacity is limited. This review examines the epidemiological overlap, immunological interactions, and diagnostic difficulties associated with DENV infection in people living with HIV (PLWH). Seroprevalence studies reveal high rates of dengue exposure among PLWH in sub-Saharan Africa, Latin America, and Southeast Asia, with increasing evidence of autochthonous transmission in non-endemic regions. Immunologically, coinfection is characterized by altered platelet function, suppressed chemokine secretion, and dysregulated T cell activation. Molecules such as CLEC5A and CD300a play key roles in the immune modulation seen in coinfected hosts. Although clinical presentations vary from mild to severe, atypical manifestations including encephalitis and hepatic dysfunction have been observed. Diagnostic confusion with acute HIV syndrome or other febrile illnesses remains a major concern. Innovations such as CRISPR-based detection systems and graphene biosensors hold promise for field-deployable diagnostics. Mathematical modeling supports integrated control strategies, and novel DENV-derived peptides like pepRF1 show potential as dual-acting therapeutics. As climate change facilitates the spread of Aedes vectors, dengue's expansion into new territories highlights the urgency of integrating arboviral surveillance with HIV care systems. This review underscores the need for enhanced diagnostics, better therapeutic options, and longitudinal research on DENV pathogenesis in immunocompromised populations.

Tinea capitis (TC), commonly known as scalp ringworm, is a dermatophytosis affecting the scalp. It represents a significant public health concern worldwide, particularly in Africa. However, epidemiological data on this infection remain limited in Cameroon. This study aimed to assess the prevalence and risk factors of TC among school-children in four regions of Cameroun. A cross-sectional study was carried out from April to June 2023 including pupils aged 5–14. First, a standardized questionnaire was administered to the participants to collect sociodemographic data. Then, the children were examined and TC lesion samples were collected and cultured onto Sabouraud Chloramphenicol-Gentamicin Agar. The cultured dermatophytes were identified based on their morphological features and with MALDI-TOF mass spectrometry.
A total of 459 children were included, of whom 118 (25.7 %) presented with TC lesions. Traditional hair braiding (OR = 0.24, 95 %CI: 0.06–0.90), and sleeping alone (OR = 0.49, 95 %CI: 0.26–0.91) were associated with a decreased risk of TC in multivariate logistic regression analysis. In contrast, male sex (OR = 3.15, 95 %CI [1.63–6.06]), hairdressing at home (OR = 2.39, 95 %CI [1.45–3.93]), and ringworm in siblings (OR = 2.79, 95 %CI [1.73–4.50]) were associated with an increased risk of TC. These results emphasise the importance of raising awareness and providing education on hygiene and hairstyling practices. Further efforts are needed strengthen health infrastructure, and implement targeted public health programmes to better control this disease in Cameroon.

Background
Meningitis caused by Escherichia coli K1 occurs only in specific cases: in neonates or in adults following trauma or in a nosocomial context resulting from procedures that create a direct entry point, such as neurosurgical procedures. Community-acquired cases in adults are rare, and those secondary to septic arthritis are even rarer.
In this article, an exceptionally uncommon case of community-acquired meningitis due to Escherichia coli O25:K1:H4 (sequence type 95) with concomitant septic arthritis at the L4/L5 level is described, emphasizing the diagnostic process, which was aided by detailed microbiological documentation.
Case presentation
A 73-year-old man with a history of hypertension, alcohol use, and atrial fibrillation presented with acute lower back pain, confusion, persistent vomiting, headache, lethargy, and low-grade fever (37.9 °C). He also demonstrated a positive Lasegue's sign and had elevated inflammatory markers without an obvious infectious source. The patient experienced a favorable outcome with no neurological sequelae after receiving treatment with ceftriaxone 2g every 12 h, initiated from the first day of arrival at the emergency department.
Conclusions
Challenging but achievable, the diagnosis was made by integrating clinical history, microbiological findings, and radiological results. In particular, multiplex PCR played a crucial role in the prompt diagnosis of Escherichia coli K1 meningitis, while also influencing the management and outcome of the patient.

International air mobility is increasing. With a changing climate in Europe, and the associated expansion of regions suitable for exotic vector habitats including mosquitoes, it is crucial to investigate possible routes for their transport over long distances. This study investigated whether exotic vectors are introduced to Europe via air traffic.
Methods
At Zürich Airport, passenger cabins of selected aircraft were vacuumed after passengers had disembarked. The samples were examined microscopically, the findings identified, and the arthropod species morphologically determined. The take-off airports were selected based on the occurrence of exotic mosquitoes of interest.
Results
A total of 37 aircraft were sampled between 2021 and 2023. No mosquitoes were detected in any of the samples. However, 12 flights, one third of all flights screened, showed the presence of different arthropods. These included beetles (Coleoptera), ants (Hymenoptera), and a fly (Diptera). None of the insects found were vectors of importance for human diseases, and there was no correlation found between presence of insects on the aircraft and the aircraft size or jetty type at destination.
Conclusions
The results of this study indicate that the risk of mosquitoes being introduced into the passenger cabin of an airplane is low. However, the survival of mosquitoes introduced from tropical regions is favoured by warming climatic conditions in Europe. We suggest that further studies using traps at airports and in aircraft cargo holds are warranted. Constant surveillance and random sampling of aircraft for arthropods, particularly at high volume hubs, are recommended.

Q fever is a zoonotic infectious disease. Objectives: The objective of this study was to detect the presence of C. burnetii in blood samples of feverish individuals (Contact with livestock; sheep, goats, and cattle, Consumption of unpasteurized dairy products) collected from hospitals at Khorramabad, Iran.
Material and methods
A total number of 199 blood samples were collected from patients with fever from August 2015 to November 2016. Nested-PCR, using specific primers targeting the Com1 and icd genes, was employed to diagnose C. burnetii.
Results
Out of 199 blood samples, 16 samples were positive with Com1 gene (8 %; 95 % CI: 5.5–17.4) primers and 13 samples were positive with icd gene (6.5 % 95 % CI: 3.9 %–10.9 %) primers (table 2 is necessary). No significant correlation was observed between the variables and the positive result of PCR (p < 0.05) according to the study conducted using SPSS software.
Conclusions
Q fever is present in patients from Khorramabad according to this study. Therefore, it should be considered as one of the possible causes of fever and non-specific symptoms in patients. It should be taken into consideration by health policy makers.
