Summary: This study retrospectively analyzed tissue samples from fatal suspected leptospirosis cases in Colombia and confirmed the presence of leptospirosis in 27% of cases. Other pathogens such as Brucella spp., Rickettsia spp., and dengue were also identified. The study highlights the importance of early and accurate recognition of leptospirosis and the need for expanded laboratory surveillance for other febrile syndromes.

Summary: In recent years, there has been a significant increase in the number of leptospirosis cases in Malaysia. A study found that 4.7% of febrile patients with dengue-like illness had leptospirosis, and 18% had positive anti-Leptospira IgM antibodies. Furthermore, one patient was found to be co-infected with leptospirosis and chikungunya virus.

Summary: This study aimed to determine the prevalence of leptospirosis among febrile patients with a suspicious clinical diagnosis of dengue fever in northern Peru. Results showed that out of 276 serum samples analyzed from patients with acute febrile illness and suspected diagnosis for dengue virus, an etiological agent was identified in 47.5% of patients, with 30.4% testing positive for DENV, 11.2% for leptospirosis, and 5.9% for co-infection by both pathogens. Additionally, no differences in symptomatology were observed among the different study groups.

Summary: This study in western India revealed a higher seroprevalence of dengue infection and a gradual increase in seroprevalence in the region. Most laboratory-confirmed dengue cases were observed in the 21-30 age group. The most common serotype detected in the tested samples was DEN-3.

Summary: The global incidence of dengue fever has increased significantly, and reporting surveillance data is crucial for understanding the scale of the problem and developing strategies for disease control. However, surveillance practices are not standardized, particularly in low- and middle-income countries. This article summarizes two decades of policy changes, literature, statistics, and dengue case data in Cambodia to identify important changes in the disease landscape and derive lessons for future surveillance and control strategies.

Summary: This study explores the Raman spectra of red blood cells from patients infected with malaria, dengue, and leptospirosis, and identifies Raman markers for red blood cell injury. The study also provides statistical tools for analyzing Raman spectral data from biological samples to identify important Raman peaks. This approach of RBC analysis can enhance our understanding of red blood cell behavior and their alterations in health and disease.

Summary: Analysis of national data in Ecuador revealed that leptospirosis is endemic in resource-poor tropical settings, with high incidence and mortality rates among adult males. Strategies for monitoring and controlling the disease should consider seasonal variations and high-risk groups.

Summary: This study evaluated the effect of sanitation on the cross-correlation between rainfall and the first symptoms of dengue fever. Results showed that the cross-correlation between rain and dengue increased as the city implemented actions to improve basic sanitation. The study suggests that cities with improved sanitation have a high correlation between dengue fever and annual precipitation, and prevention and control policies can be targeted accordingly.

Summary: This study analyzed human leptospirosis in different regions of Brazil and found heterogenous distributions with higher incidence during the rainy season and influenced by precipitation. A forecast model predicted the number of cases for 2020 and provided incidence, mortality, and case fatality rates for the period.

Summary: This study conducted differential diagnosis of tuberculosis using sputum samples collected at the early stage of the COVID-19 outbreak in Ghana, revealing a small proportion of COVID-19 patients who were also infected with tuberculosis. The findings emphasize the necessity of differential diagnosis among COVID-19 suspected cases and regular active TB surveillance in TB endemic settings.

Summary: When a monkeypox virus outbreak occurred globally in May 2022, it became crucial to have timely and accurate diagnosis. In our laboratory, we developed and assessed a real-time quantitative PCR method, which was compared with isolation results. The genomic viral load was found to be associated with virus viability.
