Rare Brain-Eating Amoeba Poses Summer Risk in Israel, Experts Advise Caution

The rare brain-eating amoeba Naegleria fowleri thrives in warm, fresh water environments such as lakes, springs, and reservoirs, posing a small but serious health risk during Israel's hot summer months. This amoeba can infect people when contaminated water enters the nose, typically during swimming, diving, or jumping into water, potentially causing a severe and often fatal brain infection.

Despite its rarity, with only 167 cases reported in the U.S. since 1962 and a very high fatality rate, awareness is crucial. The amoeba flourishes in warm, stagnant, or shallow waters, conditions increasingly common due to climate change. Infection does not occur through drinking water but only through nasal exposure.

To reduce risk, experts recommend avoiding water entering the nose by using nose clips or keeping the nose closed, especially in natural warm springs. Swimming in supervised, chlorinated pools with regular water quality checks is safer. Authorities advise heeding local health warnings about natural water sites.

Symptoms begin like a common viral illness with fever, headache, nausea, and vomiting but can rapidly worsen. Prompt medical attention is essential if symptoms appear after freshwater exposure. Dr. Dana Dror, an infectious disease specialist, emphasizes that swimming and water activities remain safe with proper precautions and awareness.

In summary, while the brain-eating amoeba is a rare threat, simple safety measures can allow Israelis to enjoy summer water activities without undue fear.
