[pic] Secondary Syphilis • Secondary syphilis occurs approximately 1–6 months (commonly 6 to 8 weeks) after the primary infection. • There are many different manifestations of secondary disease. • A patient with syphilis is most contagious when he or she has secondary syphilis. • There may be a symmetrical reddish pink non-itchy rash on the trunk and extremities. • This is accompanied with mild constitutional systems, often described as flu-like. • These rashes tend to be symmetrical can involve the palms of the hands and the soles of the feet. • In moist areas of the body such as anus, vulva, perineum, mouth, and axilla the rash becomes flat, broad, whitish lesions known as condylomata lata. • All of these lesions are infectious and harbor active treponema organisms. Tertiary Syphilis • Tertiary syphilis usually occurs 1–10 years after the initial infection, though in some • Cases it can take up to 50 years. • This stage is characterized by the formation of gummas which are soft, tumor-like lesions of inflammation known as granulomas. • They may appear almost anywhere in the body including the skeleton and brain. • The more severe manifestations include neurosyphilis and cardiovascular syphilis • The incubation period of syphilis varies from 10 days to 10 weeks with average of 3 weeks. STEP 5: Treatment of Syphilis (10 minutes) • The drug of choice is intramuscular Benzathine benzylpenicillin • Doxycycline • Erythromycin STEP 6: Prevention and Control of Syphilis (30 minutes) |Activity: Group discussion (15 minutes) | | | |DIVIDE students into small manageable groups | | | |ASK students to discuss on the following question | | | |What are the prevention and control measures of Syphilis? | | | |ALLOW students to discuss for 10 minutes | | | |ALLOW few groups to present and the rest to add points not mentioned | | | |WRITE their response on
