Ministry of Health Urges Against Swimming in Certain Areas of Lake Sevan

The Ministry of Health is urging citizens to avoid swimming in certain areas along the shores of Lake Sevan where cyanobacteria are observed.

Cyanobacteria, or blue-green algae, are found worldwide, particularly in stagnant, nutrient-rich waters. Some species of these organisms produce toxins that can adversely affect the health of both animals and humans. People can be exposed to these toxins by drinking the 'blooming' water, swimming in it, or inadvertently swallowing it.

Swimming in such water may result in symptoms including asthma, eye irritation, rashes, especially around the mouth and nose, skin irritation, and allergic reactions. Inadvertently swallowing the water can lead to stomach pain, nausea, vomiting, diarrhea, fever, sore throat, headaches, muscle and joint pain, and sores in the oral cavity, as well as liver-related issues.

To avoid health problems of this nature, the Ministry of Health recommends:

• Not swimming in areas where algae are present
• Prohibiting children from swimming in unauthorized areas
• Seeking immediate medical attention if the aforementioned symptoms are observed

Although laboratory studies have indicated that the most at-risk areas are the beaches near Vardenik and Martuni communities, it is important to note that algae, being living organisms, can move and alter species ratios due to changes in air and water temperature, wind direction, and strength. Therefore, we once again advise against swimming in places where algae are present in the water.
