How does leprosy spread from one person to another?

How can you protect yourself from leprosy?

Prevention of contact with droplets from nasal and other secretions from patients with untreated M. leprae infection is currently the most effective way to avoid the disease. Treatment of patients with appropriate antibiotics stops the person from spreading the disease.

Can leprosy live on surfaces?

Outside an animal or person's body, M. leprae does not appear able to survive for long in the environment. However, free-living amoeba in soil have recently been found to protect M. leprae bacteria placed in soil.

Is leprosy transmitted through water?

Water was regarded as a reservoir and infectious source of M. leprae. Transmission of leprosy through the contaminated water was strongly suggested by epidemiological analysis.

What animals carry leprosy?

Armadillos are known to carry leprosy — in fact, they are the only wild animals other than humans upon which the picky M. leprae can stand to live — and scientists suspected that these anomalous cases were due to contact with the little armored tootsie rolls.

Can leprosy spread through blood?

After a 5-year follow-up period, six individuals with positive markers developed leprosy, raising the hypothesis that asymptomatic infection among blood donors may be an undisclosed mode of leprosy transmission via transfusion.

Does leprosy have a vaccine?

There are two leprosy vaccine candidates, MIP in India (82) and LepVax (66), and the TB vaccine pipeline is much more advanced and diverse than the one for leprosy.

Can leprosy be painful?

Pain is common among patients with leprosy and is multifactorial, but especially associated with nerve damage, leprosy reactions, and neuritis. This is an important consideration, as even after adequate treatment and bacteriological cure, pain may present as a new disabling condition.
