This Flesh-Eating Parasite Spread by Sand Flies Has Foothold in u.s., Appears to Be Endemic in Texas, CDC Scientists Report
Once thought to be a danger largely reserved for travelers, a flesh-eating parasite known as Leishmania mexicana is now likely spreading locally through some sand flies native to the southern U.S., a new Centers for Disease Control and Prevention analysis has concluded.
Skin sores caused by Leishmania mexicana typically erupt weeks to months after people are bitten by an infected fly.
The parasite’s lesions can last for years, the CDC says, leading to scarring in its wake.
Hospitals have some options for drugs to use in trying to treat patients suffering from this disease caused by the parasite, which doctors call cutaneous leishmaniasis, though the CDC says not all cases require treatment with medications to combat the parasite.
No vaccine is available for leishmaniasis in humans.
The immediate concern triggered by the discovery is raising awareness of the parasite, officials say, which now appears to be “endemic” in Texas as well as some southern border states.
