Swimming Pool-Associated Vittaforma-Like Microsporidia Linked to Microsporidial Keratoconjunctivitis Outbreak, Taiwan

Jung-Sheng Chen et al. Emerg Infect Dis. 2019 Nov.

Abstract

We analyzed 2 batches of environmental samples after a microsporidial keratoconjunctivitis outbreak in Taiwan. Results indicated a transmission route from a parking lot to a foot washing pool to a swimming pool and suggested that accumulation of mud in the foot washing pool during the rainy season might be a risk factor.

Keywords: Taiwan; Vittaforma corneae; Vittaforma-like microsporidia; keratitis; microsporidia; microsporidial keratoconjunctivitis; parasites; swimming resort; transmission route.
