Objectives
Influenza-like illness (ILI) caused by respiratory viruses results in various respiratory clinical manifestations. The ILI002 prospective observational cohort study aimed to describe viral agents, seasonality, and outcomes of patients with ILI during four seasons in the influenza H1N1-pandemic and post-pandemic years (2010-2014).
Methods
Patients from six Mexican hospitals were enrolled from April 2010 to March 2014. Clinical data and nasopharyngeal swabs were obtained and tested for viral respiratory pathogens by real-time reverse-transcription polymerase chain reaction.
Results
Of the 5662 enrolled participants, 64.9% were adults and 35.1% were children. Among the 5629 participants with single-pathogen detection, rhinovirus (20.2%), influenza virus (11.2%), respiratory syncytial virus (RSV) (7.2%), and coronavirus (6.8%) were the most frequent pathogens. Co-infection occurred in 14.5% of cases; 49.3% of participants required hospitalization, particularly in RSV cases (42.9% adults, 89.6% children). The mortality rate was 2.8% higher among older adult participants and those with comorbidities. Influenza H1N1 had the highest mortality rate, yet almost half of the deceased had no pathogen. Rhinovirus persisted year-round, while influenza, coronavirus, and RSV peaked during cooler months.
Conclusions
Analyses showed that some viruses causing ILI may lead to severe disease and hospitalization irrespective of comorbidities. These findings may help in decision-making about public health policies on prevention measures, vaccination, treatment, and administration of health care.

Objectives
Vaccination and the emergence of the highly transmissible Omicron variant changed the fate of the COVID-19 pandemic. It is very challenging to estimate the number of lives saved by vaccination given the multiple doses of vaccination, the time-varying nature of transmissibility, the waning of immunity, and the presence of immune evasion.
Methods
We established a S-SV-E-I-T-D-R model to simulate the number of lives saved by vaccination in six states in the United States (U.S.) from March 5, 2020, to March 23, 2023. The cumulative number of deaths were estimated under three vaccination scenarios based on two assumptions. Additionally, immune evasion by the Omicron and loss of protection afforded by vaccination or infection were considered.
Results
The number of deaths averted by COVID-19 vaccinations (including three doses) ranged from 0.154-0.295% of the total population across six states. The number of deaths averted by the third dose ranged from 0.008-0.017% of the total population.
Conclusions
Our estimate of death averted by COVID-19 vaccination in the U.S. was largely in line with an official estimate (at a level of 0.15-0.20% of the total population). We found that the additional contribution of the third dose was small but significant.

Objectives
Candida species frequently cause bloodstream infections; however, there is a lack of epidemiological studies on candidemia in Oman.
Methods
To address this, we conducted a retrospective study at Sultan Qaboos Comprehensive Cancer and Research Center from October 2021 to October 2023.
Results
Our study identified 27 episodes of candidemia among 26 patients with cancer, with an incidence of 4.9 per 1000 admissions. Non-albicans Candida (NAC) prevailed over C. albicans (70.37% vs 29.62%), with C. glabrata as the predominant NAC species (n = 10; 37%). The 30-day mortality rate was 40.7%, showing no significant difference between NAC and C. albicans but was notably higher in critically ill patients (P = 0.03).
Conclusion
In Oman, NAC surpasses C. albicans as a causative pathogen for candidemia with a high mortality rate.

Objectives
To examine the epidemiology of hospitalized cases of malaria in indigenous people living in the municipalities of Roraima in the northern Brazilian Amazon from 2008 to 2022.
Methods
Ecological study using secondary data and spatiotemporal analyses based on thematic maps. Average rates were calculated per study period and spatiotemporal clusters were estimated from spatial statistics.
Results
Of the 541 medical records, 77.08% were related to Plasmodium vivax. Higher rates were observed in municipalities in the south and center of the state. The rates increased throughout the study period. The analysis generated three clusters.
Conclusions
Although Roraima has characteristics that worsen the malaria problem, no studies were found that examined the transmission of the disease in the state as a whole. This increases the importance of this study, which contributes to the discussion in the field of indigenous health.

Objectives
Human T-lymphotropic virus 1 infection is endemic in the French Antilles, French Guiana, and sub-Saharan Africa, the origin of many immigrants currently living in France. There are no national screening recommendations outside of the regulatory obligations concerning donations of blood, tissue, gametes, or milk to a lactarium. This study aimed to investigate the screening and diagnostic practices for this infection in France.
Methods
Serological statistics for regulatory, antenatal, sexually transmitted infections (for CeGIDDs (Centre Gratuit d'Information, de Dépistage et de Diagnostic des Infections Sexuellement Transmissibles), which are public sexual health clinics), accidental exposure to blood screenings, and diagnosis since January 1, 2018 were collected from 23 hospital laboratories (two in the French Antilles, 21 in mainland France) associated with 55 hospitals and 22 maternity units.
Results
A total absence of antenatal screening was reported by 75% of the laboratories associated with maternity units in mainland France. All the laboratories in mainland France reported an absence of screening in the accidental exposure to blood context, as did all the laboratories in mainland France associated with a CeGIDD in the context of sexually transmitted infection screening. Conversely, screening in accordance with the existing regulations was generally systematically carried out. The most frequently reported diagnostic contexts were hematology and neurology.
Conclusions
This study reveals an underscreening of human T-lymphotropic virus 1 in the hospital laboratories of mainland France.
目标人类 T 淋巴细胞病毒 1 感染在法属安的列斯群岛、法属圭亚那和撒哈拉以南非洲地区流行,这些地区是目前居住在法国的许多移民的原籍地。除了有关向哺乳室捐献血液、组织、配子或牛奶的监管义务外,目前还没有全国性的筛查建议。本研究旨在调查法国对这种感染的筛查和诊断方法。方法从与 55 家医院和 22 家产科医院相关的 23 家医院实验室(2 家位于法属安的列斯群岛,21 家位于法国本土)收集了自 2018 年 1 月 1 日以来有关监管、产前、性传播感染(CeGIDDs(Centre Gratuit d'Information, de Dépistage et de Diagnostic des Infections Sexuellement Transmissibles),即公共性健康诊所)、意外接触血液筛查和诊断的血清学统计数据。结果75%与法国本土产科医院有关联的实验室报告完全没有进行产前筛查。法国本土的所有实验室均报告未进行意外接触血液筛查,法国本土与 CeGIDD 有关联的所有实验室也报告未进行性传播感染筛查。相反,根据现行法规进行的筛查一般都是系统性的。本研究显示,法国本土医院实验室对人类 T 淋巴细胞病毒 1 的筛查不足。

Objectives
Hepatitis B virus (HBV) is endemic in West Africa. Because of immigration to the United States, screening and transition to long-term care is a significant public health concern. We describe the challenges of integrating individuals identified in a screening program into long-term care and the spectrum of disease severity.
Methods
Between 2019 and 2023, 749 individuals were screened. Beginning 2022, all were offered a free serologic evaluation. Details of the previous diagnosis, HBV care, the serologic evaluation, aspartate aminotransferase to platelet ratio index, and Fibrosis index-4 scores were recorded. The results of transient elastography (TE) were correlated with the serologic evaluation.
Results
A total of 75 (10%) individuals were hepatitis B surface antigen–positive, including 58 (77.3%) previously and 17 (22.7%) newly diagnosed. Despite attempts at linkage to care, only 14 (37.8%) of those diagnosed before the offer continued and/or entered long-term care. A total of 63 of 75 (84%) returned for the evaluation. Among 56 HBV treatment-naïve individuals, 66.1% had a serologic profile consistent with the carrier state. A total of 10 (18.2%) individuals met the criteria for HBV therapy, and 10 (21.7%) had ≥F2 fibrosis on TE. There was no correlation between aspartate aminotransferase to platelet ratio index and Fibrosis index-4 scores and TE. Eight (29.6%) of 27 patients with a profile of the HBV carrier state had ≥F2 fibrosis.
Conclusion
Integration of individuals with HBV from West Africa identified in a screening program into long-term care is challenging. Inclusion of a serologic evaluation in programs for immigrant communities should be considered. Up to 30% of individuals with a serologic profile consistent with the HBV carrier state may have ≥F2 fibrosis.

Objectives
Although several studies have investigated the effects of temperature on the incidence of tuberculosis (TB) in a single city or region, few studies have investigated the variations in this association using nationwide data. This study aimed to quantify the association between temporal variations in TB incidence and temperature across Japan.
Methods
The data on the weekly number of newly confirmed TB cases and meteorological variables in 47 Japanese prefectures from 2007 to 2019 were collected. The exposure-response relationships between TB incidence and temperature were quantified using a distributed lag nonlinear model for each prefecture, and estimates from all prefectures were then pooled using a meta-regression model to derive nationwide average associations.
Results
This study included 335,060 patients with TB. Compared to those with minimum risk temperature on TB incidence (10th percentile at 4.45°C), people who were exposed to the highest temperature concentrations had a 52.0% (relative risk 1.52, 95% confidence interval 1.04-2.23) higher risk for TB incidence at the 99th percentile (30.1°C). Our results also emphasized the heterogeneity of these associations in different prefectures. Conclusions: Strengthening monitoring and public health strategies aimed at controlling temperature-related TB may be more effective when tailored to region-specific meteorological conditions.

Objectives
This study aims to assess the impact of the 2022 floods in Pakistan on the incidence of vaccine-preventable diseases (VPDs) in flood-affected regions, specifically focusing on areas with traditionally low vaccination coverage.
Design
Weekly incidence data of VPDs from September to November 2021 and 2022 were collected and analyzed for the provinces of Sindh, Khyber Pakhtunkhwa, and Baluchistan. The study compared year-on-year changes in disease incidence to evaluate the effect of the floods on disease burden.
Results
The analysis revealed significant increases in the incidence of various VPDs in the flood-affected regions compared to the previous year. Diseases such as pertussis showed a 171% increase, while mumps exhibited nearly a 1000% increase in reported cases. Other diseases including polio, diphtheria, neonatal tetanus, measles, chickenpox, and rubella also experienced substantial rises in case numbers. Concurrently, cases of lower respiratory tract illnesses and diarrheal diseases in children under five years old surged notably.
Conclusions
The findings underscored the failure of relief and healthcare efforts in managing vaccine-preventable diseases in flood-affected areas of Pakistan. The study highlights an urgent need for targeted intervention strategies, including enhanced immunization drives and healthcare infrastructure improvements in vulnerable regions. The post-flood scenario presents a critical opportunity to address existing challenges in vaccination coverage and to mitigate future disease outbreaks through comprehensive public health initiatives.

We present a case report about a 26-year-old female with a Mycobacterium wolinskyi surgical site infection after bilateral breast augmentation. In a unique approach compared with previously reported cases, the patient was successfully treated in an outpatient setting using only orally administered cotrimoxazole (trimethoprim-sulfamethoxazole) and ciprofloxacin with one-sided preservation of the breast prothesis. We also provide a comprehensive overview of all report cases of M. wolinskyi infections available in the PubMed database until December 2023 and compare the different diagnostic and therapeutic approaches.

Melioidosis, an emerging infectious disease caused by the Gram-negative bacillus Burkholderia pseudomallei, is massively underdiagnosed in many low- and middle-income countries. The disease is clinically extremely variable, has a high case fatality rate, and is assumed to be highly endemic in South Asian countries, including Nepal. The reasons for underdiagnosis include the lack of awareness among clinicians and laboratory staff and limited microbiological capacities. Because costly laboratory equipment and consumables are likely to remain a significant challenge in many melioidosis-endemic countries in the near future, it will be necessary to make optimum use of available tools and promote their stringent implementation. Therefore, we suggest that health facilities in resource-poor countries, such as Nepal, introduce a simple and low-cost diagnostic laboratory algorithm for the identification of B. pseudomallei cultures. This screening algorithm should be applied specifically to samples from patients with fever of unknown origin and risk factors for melioidosis, such as diabetes. In addition, there could also be a role of low-cost, novel, promising serological point-of-care tests, which are currently under research and development.
