Is Leishmaniasis Contagious?
Transmission of Leishmaniasis from Person to Person
Leishmaniasis is considered to be contagious between people.
Generally the infectious agent may be transmitted by saliva, air, cough, fecal-oral route,
surfaces, blood, needles, blood transfusions, sexual contact, mother to fetus, etc.
Leishmaniasis, although infectious, is not a genetic disease. It is not caused by a defective or abnormal gene.
The contagious disease, Leishmaniasis, can be transmitted:
- from person to person by blood.
- from the mother to her fetus.
Transmission of Leishmaniasis from Animals
The transmission of Leishmaniasis can be by way of:
Discussion about Contagion of Leishmaniasis:
is spread by the bite of some types of phlebotomine sand flies. Sand flies
become infected by biting an infected animal (for example, a rodent or
dog) or person. Since sand flies do not make noise when they fly, people
may not realize they are present. Sand flies are very small and may be
hard to see; they are only about one-third the size of typical mosquitos.
Sand flies usually are most active in twilight, evening, and night-time
hours (from dusk to dawn). Sand flies are less active during the hottest
time of the day. However, they will bite if they are disturbed, such as
when a person brushes up against the trunk of a tree where sand flies
are resting. Rarely, leishmaniasis is spread from a pregnant woman to
her baby. Leishmaniasis also can be spread by blood transfusions or contaminated
needles. (Source: excerpt from Leishmania Infection: DPD)
About contagion and contagiousness:
Contagion and contagiousness refers to how easily
the spread of Leishmaniasis is possible from one person to another.
Other words for contagion include "infection", "infectiousness",
"transmission" or "transmissability".
Contagiousness has nothing to do with genetics
or inheriting diseases from parents.
