###Human: What is secondary infection? ###Assistant: Hi. I have read your query and examined your picture (attachment removed to protect patient identity). It seems that you are having molluscum contagiosum and a few of them are secondarily infected. Molluscum contagiosum virus will cause multiple or single raised skin lesion. The papules are umbilicated and contain a caseous plug. This virus may sometimes get inoculated along the small skin injury, such as from shaving which is known as autoinoculation. This virus gets transmitted through direct skin contact, through swimming pool or it could be transmitted sexually (STD). 1. Skin biopsy. 2. HbsAg (hepatitis B surface antigen), anti-HCV (anti-hepatitis C virus) and HIV to rule out sexually transmitted disease. 1. Molluscum contagiosum 2. Folliculitis. Molluscum contagiosum with secondary infection. 1. Generally, it is self-limited and heals spontaneously after several months. Curettage or enucleation is a more effective treatment. 2. I suggest you to take tablet Azithromycin 500 mg once daily for three days and topical Mupirocin ointment local application twice daily for five days. Consult your specialist doctor, discuss with him or her and take the medicine with their consent. For further information consult a dermatologist online.--->
