Hepatitis E virus (HEV) is primarily transmitted via the fecal-oral route and is considered an anthropozoonosis. Genotypes with zoonotic potential (mainly HEV-3 and HEV-4) can be transmitted through the consumption of raw or undercooked pork, wild boar, deer meat, or processed products. This study aims to explore methodologies for processing meat samples to establish a protocol for HEV detection in meat.

Article Synopsis
- Sporotrichosis is a fungal disease spreading in tropical regions, especially in Belém, Brazil, prompting a study on its connection to demographics, socioeconomics, and public health from 2020 to 2022.
- The study found that women and adults are predominantly affected, mainly by the cutaneous form through cat interactions, with many patients still receiving treatment.
- The findings revealed significant health inequalities in certain neighborhoods, indicating a need for improved public health policies to address the transmission and management of this disease.

Leptospirosis is an anthropozoonosis of economic and public health importance, caused by bacteria of the genus Leptospira. Horses are deemed important in its transmission chain due to their proximity to humans, and because the species is often asymptomatic, making these animals potential silent reservoirs. In this context, the objectives of this study were to determine the prevalence of seropositive horses for Leptospira spp.

Background And Objectives: Trypanosoma cruzi is the etiologic agent of Chagas disease (CD), an anthropozoonosis from the American continent that progresses from an acute phase to an indeterminate phase, followed by a chronic symptomatic phase in around 30% of patients. In countries where T. cruzi is not endemic, many blood transfusion services test blood donors who have stayed in an endemic country ('at-risk stay')-even if they do not present with other risk factors.

Article Synopsis
- Leptospirosis is more prevalent in tropical regions but can require ICU care globally; this study compares severe cases in Réunion (tropical) and mainland France (temperate) to understand clinical outcomes and characteristics.
- The study analyzed two groups of ICU patients with severe leptospirosis, finding that while patient demographics differed (e.g., metropolitan patients were older), severity, length of stay, and mortality rates were similar across both regions.
- Three distinct clinical phenotypes were identified: hepato-renal leptospirosis (54.5% with 8.3% mortality), moderately severe leptospirosis (38.5% with 1.8% mortality), and very severe leptospirosis (7
