GEORGE TOWN, Cayman Islands (CMC) — The Cayman Islands has confirmed one case of cyclosporiasis, but public health officials say the infection was acquired overseas and there is no evidence of local transmission.

The confirmation comes as the United States (US) investigates a widespread outbreak of intestinal illness.

More than 1,600 domestically acquired cases have been confirmed since May, with thousands more under investigation. US health officials believe the outbreak may be linked to contaminated packaged lettuce and other leafy greens, although the source has not yet been identified.
