"Rapid Spread of Flesh-Eating Parasitic Disease in America"

The Centers for Disease Control and Prevention (CDC) has identified 1,222 cases of leishmaniasis, a parasitic disease spread by infected sandfly bites, in US citizens between 2005 and 2019. Previously, most cases were linked to travel or living in other countries, but the CDC's new findings suggest that 86 recent cases were found in people with no recent travel history. The majority of cases were found in Texas, but there are reports of cases in other southern US states. While the disease does not pose a serious public health risk to citizens, health professionals are being urged to increase awareness and surveillance to better understand the nature of the disease.

"Rapid Spread of Disfiguring Tropical Disease Alarms CDC Scientists in the US"

The CDC has discovered evidence of a unique strain of cutaneous leishmaniasis in U.S. residents with no travel history, indicating local transmission of the disease by domestic sandflies. This raises concerns that the more severe visceral leishmaniasis could establish in U.S. sandflies through imported dogs carrying the pathogen. Genetic analysis revealed a distinct genetic fingerprint of the disease in non-travelers, suggesting a locally derived strain. Cutaneous leishmaniasis can cause disfiguring scars and is mainly found in low-income countries. The CDC hopes that by identifying the emergence of locally acquired cases, it will be easier to detect the disease in new areas. Additionally, there is growing concern that imported dogs could introduce the life-threatening visceral leishmaniasis to domestic sandfly populations.
