Sea Lice Bites Meaning

In this article of Best Body Health Tips learn everything about sea lice meaning, symptoms, causes, treatment, prevention and contagious, etc.

Cooling down in the seawater during the hot summer days seems to be one of the great pleasures of life until we get an itchy, red rash on our bodies a few hours after stepping out of the water.
If we are swimming in the Atlantic Ocean, the Gulf of Mexico, or the Caribbean Sea, we can become victims of the rash, which is also called the condition of sea lice. Although such a condition can cause itching and discomfort on our body for a few days (or a week), it usually does not have any permanent effect on our body.

Sea lice are skin irritations caused by small jellyfish larvae trapped under bathing suits in the ocean. Larvae release swollen, stinging cells that cause itching, burning, and red bumps on the skin of our bodies when they feel pressure. Doctors call it sea bath eruption or pica-pica in their own language, which in Spanish means “itch-itch”.

Although we do call them sea lice, these larvae usually have no relation to the lice they produce on our heads. These aren’t even the sea lice that bite, caused by a fish bite. However, the term has stuck a bit over time.

While skin irritations usually range from mild to moderate, some people may experience symptoms with more serious side effects, such as a high fever in children.

While this term was first identified in areas along the southern coast of the US state of Florida, it was later recognized in tropical and subtropical regions throughout the world. Its outbreak is usually very severe and severe between the months of March to August.

We can feel the symptoms of sea lice bites immediately after touching our skin with seawater. We might describe early symptoms as “prick” sensations. After this time, usually our skin starts itching. Additional symptoms may include the following:


High Fever

Pain in body joints and muscles

Diarrhea and lose motion

Lethargy in the body

Nauseous or nervous

Rash on the bottom of the bathing suit

Coming together of red bumps that may resemble a large, red mass

The larvae of jellyfish are also particularly fond of hair, which is why many people begin to experience bites on the back of their necks. However, it must be kept in mind that even though they stick to our hair, they are not head lice.

The rash usually stays on our body for 2-4 days. However, some people may have a rash on the body for up to 2 weeks after this infection. Children are especially at risk of experiencing severe symptoms associated with this infection, which can include nausea and high fever.

Sea Lice Bites Causes

Sea bather eruptions usually occur during the hot summer months, when strong winds bring thimble jellyfish and anemone larvae to the shoreline. Sea lice bites are common in Palm Beach and Broward counties in Florida. Because where the winds of the Gulf Stream below the currents.

The larvae get trapped inside the swimsuit while swimming in the ocean. Larvae contain stinging cells known as nematocysts. When the larvae rub on the skin, skin irritation is experienced which is known as sea lice bite.

Bite-tight bathing suits tend to wear out because of the extra friction. So, a towel rubs against the skin.

It can also occur in the body if the swimsuit is not washing or dried back. Since stinging cells cannot survive, they can live on clothing.

Sea Lice Bites Treatment

Sea lice bites usually treat with over-the-counter remedies. For example, applying 1% hydrocortisone cream to the bite site 2-3 times a day for 1-2 weeks helps reduce itching and swelling. Other steps you can take include the following:

Applying diluted vinegar or rubbing alcohol to the inflamed body areas

Applying cloth-covered ice packs to the affected areas

Taking nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and aspirin, to prevent pain and swelling. However, one thing to remember is that children under the age of 18 should not take aspirin

Sometimes, a person needs to seek medical advice if they have a severe reaction to sea lice bite. A doctor may prescribe prednisone in the form of oral corticosteroids.

Symptoms of sea lice bites go away within four days with treatment.

Sea Lice Bites Prevention

There is no guaranteed way to prevent sea lice other than staying out of the water. But there are ways to avoid the rash on the body.

The jellyfish larval season is from March to August. Their number is highest between April and July. Meanwhile, swimming in the sea does not mean that we will definitely find sea lice. Outbreaks come and go.

Always listen to local beach reports and pay attention to beach flags or warning signs. In Florida, a common location for these jellyfish larvae is purple flags to warn swimmers of the presence of stinging critters in the water.

Keep information related to winds and currents also. The likelihood of an outbreak increases when the Gulf Stream passes closest to the coast. They are also found in greater abundance in places where strong easterly winds combine with changes in currents to bring the larvae closer to shore.

T-shirts can trap more jellyfish larvae against your skin, so don’t wear them in the ocean. For this reason, women prefer to wear two-piece bathing suits.

Sea Lice Bites Contagious Or Not

No, sea lice bites are not contagious. Once someone has had sea lice bite, they cannot pass it on to another person.

However, it may happen that if someone lends another person their swimsuit without washing it, that other person may get pimples from the cells. Therefore, the swimsuit should always be wash and dry in the hot heat.
