Chikungunya Virus Shedding in Semen: A Case Series.

BACKGROUND: Chikungunya is a viral disease that is transmitted by mosquitoes. It is characterized by an acute onset of fever and severe arthralgia. METHODS: We describe six cases of acute and post-acute chikungunya in which viral RNA was detected in semen. CONCLUSIONS: The most prolonged detection period was 56 days after illness onset. We attempted to cultivate positive semen samples, but virus isolation was unsuccessful in all cases.
