How Darwin get chagas's disease?

Charles Darwin is thought to have contracted Chagas disease during his voyage on the HMS Beagle in the 1830s, particularly while he was in South America. The disease is caused by the parasite Trypanosoma cruzi, which is transmitted through the feces of triatomine bugs, commonly known as "kissing bugs." It is believed that Darwin may have been exposed to these bugs or the parasite in the environment during his explorations, leading to his eventual health issues related to the disease. However, definitive evidence of this transmission is not documented.
