Is leish contagious?
Leishmaniasis is not contagious person to person. Sand fly bites are necessary to transfer the parasite from the sand fly to the human. The sand fly is the vector for the disease. The protozoan parasite has a life cycle that requires development in both the sand fly and a mammal (human, dogs and others).

What is CARD9 deficiency?
CARD9 deficiency is a rare disorder of the immune system caused by changes (mutations) in the gene called caspase recruitment domain family member 9 (CARD9). CARD9 deficiency leads to increased susceptibility to certain fungal infections.
What causes mucocutaneous manifestations?
Mucocutaneous disease, also called espundia in South America, usually develop by metastasis from disseminated protozoa rather than by local spread. This condition is most commonly caused by New World species, although Old World L aethiopica has also been reported to cause this syndrome.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
