Healthcare professionals (HCPs) working in paediatric settings are routinely exposed to respiratory pathogens, increasing their risk of asymptomatic colonisation by meningitis-associated bacteria. This study is the first to assess oropharyngeal and n...

Schistosomiasis remains a significant public health concern, with Schistosoma japonicum infection endemic in certain regions of Asia. Praziquantel (PZQ), primarily known as an effective therapeutic agent, has recently shown potential as a prophylacti...

Background: Recurrent malaria refers to repeated episodes of the disease in the same individual. Plasmodium vivax is known for its ability to relapse due to dormant liver-stage hypnozoites and poses a particular risk to travelers returning from endem...

In 2024, a significant pertussis surge in Queensland, Australia, strained public health resources. To improve investigation efficiency, the Wide Bay Public Health Unit introduced an online survey for pertussis cases on 1 August 2024, which collected...

Compliance with standard treatment guidelines (STGs) for the empirical management of uncomplicated urinary tract infections (UTIs) ensures the rational use of antibiotics and mitigates antimicrobial resistance. Operational research (OR) at Korle Bu P...

Background and Aims: Hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) remain significant global public health issues despite advances in their diagnosis and treatment. Our country is in a medium endemic region...

Background: Human nasal myiasis is a rare zoonotic infection caused by Oestrus ovis with a non-specific clinical presentation that can mimic more common conditions such as allergic rhinitis. Objective: To report a series of nasal myiasis cases in imm...

Guinea pigs (Cavia porcellus) are bred as livestock in South American countries from the Andean region, including Ecuador. Despite their importance for the local rural economy, no public health management guidelines have ever been implemented for gui...

Understanding Plasmodium falciparum population genetic diversity is crucial to assess the impact of malaria control interventions. This study investigated P. falciparum genetic diversity using merozoite surface protein 1 (msp1), msp2 and glutamate-ri...

Leishmaniasis is a parasitic disease transmitted by female sandflies of the genus Lutzomyia. Ecuador is divided into three distinct natural regions: the Andes, the Coast, and Amazonia, each characterized by significant variations in altitude and clim...

At a veterinary hospital in southern Chile, we conducted an epidemiological study involving domestic dogs, cats, and horses to determine the seropositivity for pathogenic Leptospira spp., identify the infecting serogroups, measure antibody titers, an...

Introduction: Scrub typhus is caused by Gram-negative bacteria, Orientia tsutsugamushi. Humans are the dead-end host of scrub typhus. Currently, there is no vaccine available. The disease can be fatal without appropriate treatment. Here, we present t...

Vector-borne diseases (VBDs) account for more than 17% of all infectious diseases, causing over 700,000 deaths annually, particularly among the poorest populations in tropical and subtropical areas. Climate change, particularly global warming, and ce...

Kala-azar is associated with case-fatality rates as high as 10% in certain regions. Early identification of mortality biomarkers can significantly reduce this risk. This study, strengthened by a relatively high number of kala-azar-related deaths, aim...

Malaria continues to affect millions of people around the world. Current control strategies have not been sufficient, and additional tools are required for malaria elimination. A promising approach is the use of bacteria from the mosquito microbiota,...

We aimed to compare the proportion of tuberculosis infection among social contacts of male tuberculosis Index case with and without alcohol use in the Puducherry district. A cross-sectional study using ego-centric approach was conducted between Novem...

Background: Neurocysticercosis (NCC) and HIV co-infection frequently occur in sub-Saharan Africa, yet the accuracy of available serological tests for NCC in immunosuppressed patients is uncertain. Methodology: We performed a cross-sectional diagnosti...

Tuberculosis (TB) continues to be the world’s deadliest infectious disease, with an estimated 10.8 million new cases reported in 2023, of which India alone accounted for 28% of the global burden. This study aims to evaluate the impact of tuberc...

Cutaneous leishmaniasis (CL) is a vector-borne parasitic disease caused by protozoa of the Leishmania genus. Once confined to endemic regions such as the Middle East, Americas, North Africa, and Central Asia, CL is increasingly emerging in non-endemi...

Mexico has not only successfully eliminated dog-mediated human rabies in recent years, but also the last rabies case in a dog infected with the canine variant of the rabies virus was reported in 2016. Mass dog vaccination campaigns were the cornersto...

Until recently, Stenotrophomonas maltophilia was considered a low-virulence pathogen, usually found as an environmental commensal and colonizer of moist abiotic surfaces. Lately, it has increasingly been implicated in invasive infections with high as...
