5 Risks to Beware of While Summertime Swimming

340

FLORIDA – June 25, 2018

You were waiting for summer for so long. You were dreaming to go to the beach or at least to the pool and finally be able to swim, enjoying the warm pleasant water and sunshine. Here it comes. But be careful, there's always a possibility of contamination, regardless of whether it's fresh or salt water, chlorinated pools or the neighborhood splash pad.

You may never contract the following illnesses, but they do exist and experts say you should know about them.

Cyanobacteria (toxic algae)

Cyanobacteria, also known as blue-green algae, are microscopic organisms thrive in all types of warm water (fresh, combined salt and freshwater and marine water) with a weak co-flowing.

According to the Centers for Disease Control and Prevention (CDC), Cyanobacteria tend to outcompete other algae when water temperatures get above about 20 degrees Celsius (68 degrees Fahrenheit), they outcompete most other organisms and persist for long periods of time.

Cyanobacteria can produce neurotoxinscytotoxinsendotoxins, and hepatotoxins (e.g., the microcystin-producing bacteria genus microcystis), which are collectively known as cyanotoxins.

Specific toxins include, anatoxin-aanatoxin-asaplysiatoxin, cyanopeptolin, cylindrospermopsindomoic acidnodularin R(from Nodularia), neosaxitoxin, and saxitoxin. Cyanobacteria reproduce explosively under certain conditions. This results in algal blooms, which can become harmful to other species, and pose a danger to humans and animals, if the cyanobacteria involved produce toxins. Several cases of human poisoning have been documented, but a lack of knowledge prevents an accurate assessment of the risks.

So, if you see a water, that is discolored or has a foamy or scummy surface, you should know that it’s not safe. We recommend you to stay away from that water and keep your pets away too.

Naegleria fowleri (brain-eating amoeba)

Less than 2 weeks ago, this deadly parasite was discovered in Louisiana. https://www.cbsnews.com/news/brain-eating-amoeba-found-louisiana-terrebonne-parish-pointe-aux-chenes/

Naegleria fowleri, colloquially known as the "brain-eating amoeba", is a species of the genus Naegleria, belonging to the phylum Percolozoa. It is a free-living, bacteria-eating amoeba that can be pathogenic, causing a fulminant (sudden and severe) brain infection called naegleriasis, also known as primary amoebic meningoencephalitis (PAM). This microorganism is typically found in bodies of warm freshwater, such as ponds, lakes, rivers, and hot springs. It is also found in the soil near warm-water discharges of industrial plants, and in unchlorinated or minimally-chlorinated swimming pools. It can be seen in either an amoeboid or temporary flagellate stage.

CDC researchers said people do not become infected from drinking contaminated water.

 Infections most often occur when water containing N. fowleri is inhaled through the nose, where it then enters the nasal and olfactory nerve tissue, traveling to the brain through the cribriform plateN. fowleri normally eat bacteria, but during human infections, the trophozoites consume astrocytes and neurons.

It takes 1–9 days (average 5) for symptoms to appear after nasal exposure to N. fowleri flagellates. Symptoms may include headache, fever and nausea. Later symptoms can include stiff neck, confusion, lack of attention, loss of balance, seizures, and hallucinations. Once symptoms begin to appear, death will usually occur within two weeks. A person infected with N. fowleri cannot spread the infection to another person.

Most infections occur during July, August and September when there is prolonged heat, higher water temperatures and lower water levels.

Vibriosis (flesh-eating bacteria)

Vibriosis causes an estimated 80,000 illnesses and 100 deaths in the United States every year. About 52,000 of these illnesses are estimated to be the result of eating contaminated food. People with vibriosis become infected by consuming raw or undercooked seafood or exposing a wound to seawater.

Most people become infected by eating raw or undercooked shellfish, particularly oysters. Certain Vibrio species can also cause a skin infection when an open wound is exposed to brackish or salt water. Brackish water is a mixture of fresh and sea water. It is often found where rivers meet the sea.

Vibrio bacteria naturally live in certain coastal waters, according to the CDC, and are measured in higher concentrations between May and October.

“If you have open wounds, cuts, abrasions and sores, stay out of [brackish and warm salt water.] Persons with low immune systems, cancer, diabetes, liver disease and other chronic conditions should avoid eating raw or undercooked seafood, especially oysters,” Dr. Karen Landers, assistant state health officer with the Alabama Department of Public Health, said in a statement.

Cercarial Dermatitis (swimmer’s itch parasites)

Swimmer’s itch or cercarial dermatitis, is a short-term immune reaction occurring in the skin of humans that have been infected by water-borne schistosomatidae. Symptoms, which include itchy, raised papules, commonly occur within hours of infection and do not generally last more than a week. It is common in freshwater, brackish and marine habitats worldwide. Incidence may be on the rise, although this may also be attributed to better monitoring. Nevertheless, the condition has been regarded as emerging infectious disease.

There are no permanent effects to people from this condition. Orally administered hydroxyzine, an antihistamine, is sometimes prescribed to treat swimmer's itch and similar dermal allergic reactions. In addition, bathing in oatmealbaking soda, or Epsom salts can also provide relief of symptoms.

Cryptosporidiosis, also known as crypto, is a parasitic disease parasitic infection is often found in swimming pools and water playgrounds. It can survive for up to 10 days in properly chlorinated water, making it extremely hard to kill.

 It affects the distal small intestine and can affect the respiratory tract in both immunocompetent (i.e., individuals with a normal functioning immune system) and immunocompromised (e.g., persons with HIV/AIDS or autoimmune disorders) individuals, resulting in watery diarrhea with or without an unexplained cough. In immunocompromised individuals, the symptoms are particularly severe and can be fatal. It is primarily spread through the fecal-oral route, often through contaminated water; recent evidence suggests that it can also be transmitted via fomites in respiratory secretions.

This Outbreaks occur when swimmers swallow water contaminated with fecal matter.

It is impossible to completely eliminate the risk of infection with cryptosporidiosis, but to minimize to an acceptable level. To do this, doctors recommend to contain yourself from swimming if you have suffered an infection less than 2 weeks ago.

We hope you will never contract the described illnesses, and bathing will bring you only positive emotions and health.
