Scientists believe it is spread through particles in the air, but also say contact must be “prolonged” and “close.”
An infected person can suffer mild to severe damage to the body’s “skin, nerves, and mucous membranes.”
Moreover, patients can lose feeling in parts of their bodies and suffer permanent blindness.
Dr. Victor S. Santos, who works with a team of researchers at the Federal University of Alagoas, in Arapiraca, Brazil, told Reuters,
“As leprosy has been a neglected disease with a high potential to cause deformities, especially when it is not treated properly, I would like to reinforce the need for early identification of cases in the community with the adoption of active case search and screening of household and social contacts from all index cases,” he said.
“Such measures could minimize leprosy-related problems, as physicians and other health professionals could better care for these patients.”
Dr. Ochoa and her team studied 187 infected patients between 1973 and 2018. The report found, according to Reuters Health, that 16 percent of patients suffered “loss of protective sensation” while 26.2 percent of patients had a “visible deformity.” The problem is that cases go undiagnosed and patients aren’t symptomatic for an average of five years, according to the World Health Organization.
According to the CDC, patients with early diagnoses adhering to a combination of 2 or 3 antibiotics make full recoveries.
