“…P. megistus is a native Brazilian species with a wide spatial distribution and high epidemiological and entomological relevance due to the high rates of T. cruzi infection and its proximity to human dwellings, as it can colonize intra-and/or peridomicile areas. In 2021, P. megistus foci were described in the metropolitan region of São Paulo, with T. cruzi-infected triatomines associated with marsupials, revealing the importance of continued surveillance of synanthropic P. megistus 46 .…”

“…In addition, the coexistence of these patients with insect vectors inside their dwellings was smaller when compared to the older population (Dias, 2000), which may have led to lower awareness, or a lesser appreciation, of the vector path. However, it is important that the population is aware of the importance of the transmission of CD by its vectors, as the encounter of triatomines can occur, even if occasionally, inside residences present in metropolitan regions (Silva et al, 2020). Additionally, educational interventions may trigger actions that contribute to prevent parasitic diseases such as Chagas disease (Bianchi et al, 2020).…”

Seroprevalence of Chagas disease in Southern Brazilian cardiac patients and their knowledge about the parasitosis and vectors

Chagas disease (CD) is considered a typical low-income population sickness of the developing countries in Latin America. Given the historical relevance of CD in individuals in southern Rio Grande do Sul (RS) State, Brazil, the aim of this study was to identify the knowledge of the CD and its vectors by cardiac patients, and the prevalence of anti-T cruzi antibodies in these individuals in Pelotas, city located in Rio Grande do Sul (RS) state, Brazil. The subjects with cardiac disease were submitted to a semi-structured questionnaire as well as two serological tests in order to detect anti-T. cruzi IgG antibodies. Of the individuals that born in municipalities showing the highest triatomine infestation rates in recent decades, 81.8% were able to recognize the vector insect (p = 0.0042; OR = 5.9), and 83.3% reported either themselves or someone in their families to have CD (p = 0.043, OR = 5.2). Of the 54 patients submitted to serological analysis, only 01 patient (1.9%) was positive for anti-T. cruzi antibodies, a 55 year old man from the rural area of Canguçu county. This study provides support for the evaluation to be extended to other cardiology centers, given the importance of Chagas disease in Brazil.

“…Triatomines occurred sporadically in the municipality, with high rates of infection by T. cruzi , but with no evidence of colonization. In 2018, the first outbreak of the species P. megistus was found in the municipality of Carapicuíba, part of the MRSP, in a house located in an urban condominium very close to a forest and associated with a marsupial nest 5 . The objective of this study is to report, for the first time, the occurrence of a focus of P. megistus in the municipality of Taboão da Serra, in an urban area.…”

INTRODUCTION: This communication reports the colonization of Panstrongylus megistus in an urban area of the municipality of Taboão da Serra in the metropolitan region of São Paulo. METHODS: After receiving a notification from the population, entomological research comprising active search, collection, identification, and examination of triatomines was conducted. Wild animals were captured and examined. RESULTS: A colony of triatomines was found to be associated with dogs in the backyard of the property. CONCLUSIONS: The colonization of P. megistus shows the potential for their occupation of artificial ecotopes, which may pose a risk to the human population.
