Article Synopsis
- Hantavirus pulmonary syndrome cases in northeastern Argentina are rare, but neighboring regions have higher rates, indicating possible underreporting.
- A study was conducted to check for antibodies against orthohantavirus in small rodents in Misiones province.
- Infected rodent species, Akodon affinis montensis and Oligoryzomys nigripes, were discovered in protected areas of the province.
American cutaneous leishmaniasis (ACL) is the most prevalent form of leishmaniasis, associated with an ulcerative and stigmatizing mucocutaneous pathology. This study assessed the incidence of Leishmania (Viannia) braziliensis in members of the Argentine Army who were exposed to sandfly bites in Iguazú National Park (INP), northeastern Argentina, during an outbreak of ACL in 2019, and the presence of Leishmania in rodents, opossums and phlebotomine sandflies collected in the area of exposure. Samples from military personnel, wild animals and phlebotomine sandflies were analysed.

In Argentina, one of its main hosts is the sigmodontine rodent Oligoryzomys flavescens, a widely distributed mouse of the Pampas, Delta and Espinal ecoregions of central-east Argentina. Because the abundance of the reservoir and its proportion in the rodent community affects both virus prevalence and human exposure risk, its estimation throughout its known geographical distribution is of key importance for the design of public health strategies to prevent HPS.

- Orthohantaviruses cause Hantavirus Pulmonary Syndrome in the Americas and are primarily hosted by diverse sigmodontine rodents in South America, particularly in northeastern Argentina's Misiones province.
- The study aimed to identify virus hosts and analyze the factors affecting infection prevalence, conducting extensive live-capture sessions over two years.
- Akodon montensis was the most commonly captured rodent and the first recorded host for orthohantavirus in Argentina, with higher infection rates in larger, active males, indicating significant implications for emerging disease research.
Human health risk in urban areas depends on multiple environmental features. We performed a year-round survey in a highly urbanized district located in temperate Argentina (General San Martín, Buenos Aires) to establish baseline information about environmental hazards associated with health risks. Sampling was stratified into low and high hazardous zones according to estimated indexes previously developed for the area for four hazards: drinking water and air pollution, and mosquito and rodent infestation.
