According to Centers for Disease Control and Prevention, "swimmer's itch" or sea lice is not contagious.
Sea lice are common on area beaches during the summer as the waters warm, he said.
The warm sunny weather has many flocking to the beach, but as the Fourth of July holiday weekend approaches, officials in Florida are warning beachgoers of an unpleasant organism lurking in the water along part of the coast.
The organisms are common on beaches in the area during summer when the water is warm, he told the newspaper, but they can not live outside of salt water.
Pensacola lifeguards hoisted purple flags this week warning beachgoers of unsafe marine life after sea lice were spotted in area waters, WEAR-TV reports.
Other nearby Gulf Coast beaches in Florida and Alabama are not now affected by sea lice, AL.com reports. They are the larvae of the thimble jellyfish, according to the Florida Department of Health.
Sometimes people are unaware they are stung until a rash appears hours after being in the water, after which the itching starts.
The rash-a form of dematitis-usually subsides in a week or less, but it can be accompanied by other symptoms including nausea, vomiting, headache, muscle spasms and more.
Florida saw its worst sea lice outbreak in 1995, when an infestation spanned the state's waterfront from the Florida Keys to Jacksonville.
"It is not unusual to see evidence of 200 or more stings under a person's bathing suit", said the Florida Department of Health.
The surface area of a bathing suit may also increase the area over which someone can get stung.
"Not to go above your knee length in the water", Kapatch said. "You are a land animal and the Gulf is not our native environment".
Thoroughly clean your bathing suit after use with detergent and heated dying, not air drying.
Stings from the larvae can result in a rash known as "seabather's eruption".
According to the TV station, you should wash your swimsuit and dry it under high heat should you come in contact with the pests.
