We applied the microsatellite typing method to <em>T. asahii</em> isolates from South America and identified multiple nosocomial transmission events from hospitals in Brazil, including clusters spanning more than a decade.

However, increasing evidence of <em>T. cruzi</em> parasites in the United States in triatomine insects, domestic animals, wildlife, and humans challenges that nonendemic label. Several triatomine species are common in the southern United States, where they transmit <em>T. cruzi</em> and invade human dwellings. Wildlife, captive animals, and companion animals, especially dogs, are commonly infected with <em>T. cruzi</em> parasites in this region and serve as reservoirs. Autochthonous human cases have been reported in 8 states, most notably in Texas. Labeling the United States as non–Chagas disease–endemic perpetuates low awareness and underreporting. Classification of Chagas disease as endemic, in particular as hypoendemic, to the United States could improve surveillance, research, and public health responses.

Although humans are accidental hosts, infection can lead to hemorrhagic fever with a high fatality rate. Domestic animals play a critical role in disease transmission, but infected animals do not show clinical signs and viremia is short; thus, CCHF virus (CCHFV) infections can remain unobserved. During 2017-2019, we conducted 2 sequential observational studies followed by a multisite randomized controlled trial to determine spatial-temporal patterns and quantify drivers for CCHFV exposure in a natural host (sheep) in a CCHF-endemic area of Bulgaria. We found high-risk areas embedded in endemic regions. Animal characteristics were not correlated with seropositivity; however, a seasonality effect was observed, suggesting sampling time was a potential confounder.
