What are the side affects of sea lice?

Sea lice, which are tiny marine parasites, primarily affect fish, but they can also cause irritation in humans who come into contact with infested water. In fish, they can lead to skin lesions, stress, and secondary infections, potentially resulting in death if infestations are severe. For humans, exposure can cause skin rashes, itching, and allergic reactions, but serious health risks are rare. It's important to rinse off after swimming in infested waters to minimize irritation.
