• No protective immunity occurs in an individual infected with

trichomoniasis

STEP 4: Signs and Symptoms of Trichomoniasis (30 minutes)

|Activity: Group discussion (15 minutes) |

| |

|ALLOW few groups to present and the rest to add points not mentioned |

STEP 5: Treatment of Trichomoniasis (30 minutes)

• The treatment of choice is a single dose of metronidazole

o Metronidazole is incompatible with alcohol and must not be given to

• Treatment of as well as their partners is important even if the partner

is asymptomatic

• Prevention and control measures of Trichomoniasis are just like other

STIs

STEP 8: Evaluation (5 minutes)

• What is the mode of transmission of Trichomoniasis?

• What are signs and symptoms of Trichomoniasis?

• What is the drug of choice for treatment of Trichomoniasis?
