A patient was diagnosed to have single skin lesion of Leprosy without any AFB positive bacteria from the scrapings. What should be the treatment of this patient according to latests guidelines?
**Core Concept**
Leprosy, also known as Hansen's disease, is a chronic bacterial infection caused by Mycobacterium leprae that primarily affects the skin, peripheral nerves, and mucous membranes. The disease can present in various forms, ranging from tuberculoid to lepromatous, depending on the host's immune response.
**Why the Correct Answer is Right**
In patients with single skin lesion of leprosy without any AFB (acid-fast bacilli) positive bacteria from scrapings, the diagnosis is typically made based on clinical findings and histopathological examination. According to the latest guidelines, such patients can be treated with a short-course multidrug therapy (MDT) regimen, which includes rifampicin and clofazimine. The use of rifampicin is crucial as it has a high bactericidal activity against M. leprae, and clofazimine is added to prevent the development of resistance.
**Why Each Wrong Option is Incorrect**
**Option A:** This option may be incorrect as it does not specify the use of rifampicin, which is a cornerstone of leprosy treatment.
**Option B:** This option may be incorrect as it does not mention clofazimine, which is essential for preventing resistance.
**Option C:** This option may be incorrect as it does not specify the duration of treatment, which is essential for ensuring the complete cure of leprosy.
**Option D:** This option may be incorrect as it does not mention the use of rifampicin, which is a critical component of leprosy treatment.
**Clinical Pearl / High-Yield Fact**
It is essential to note that leprosy treatment should be continued for at least 6 months, even if the patient shows significant improvement, to prevent the development of resistance and ensure complete cure.
**Correct Answer: C.**
