Two Bathers Diagnosed with Eye Cornea Damage from Parasite in Sea of Galilee

The Israeli Ministry of Health reported two recent cases of corneal damage caused by the microscopic parasite Microsporidium in bathers at the Sea of Galilee (Lake Kinneret). The infections were identified in individuals who swam in the lake in late June and early July, with symptoms appearing up to three weeks after exposure. The parasite can penetrate the outer layer of the eye, causing significant inflammation, pain, blurred vision, redness, and a sensation of a foreign body in the eye.

Health officials emphasized that swimming in the Sea of Galilee remains safe and that there is no risk from drinking the lake water, which undergoes treatment and monitoring. However, they urge anyone who has recently bathed in the lake and experiences eye redness, pain, or irritation to seek prompt ophthalmological evaluation. Early diagnosis is important, especially if symptoms worsen or vision deteriorates, as the parasite-induced keratitis requires medical attention.

The Ministry highlighted that symptoms may be delayed, complicating the connection to lake exposure, and cautioned against self-medicating with eye drops, which could mask the condition. The announcement comes during peak summer season when many visitors swim and engage in water sports at the lake. The Ministry continues to monitor the situation and advises the public to remain vigilant for eye symptoms following lake visits.
