Each summer, thousands of people visit their neighborhood swimming pools and water parks seeking relief from the South’s heat and humidity.
What most don’t take into consideration is that they might be risking their health.
Parasites and bacteria that live in the water can potentially make people sick.
Only in South Carolina, there are about 6,000 public pools, as per Robert Yanity, spokesman for the state Department of Health and Environmental Control. DHEC actually issues yearly operating permits for the pools and also performs surprise inspections throughout the summer period.
DHEC however, does not maintain a public online database of swimming pool regulation violators. DHEC conducts three tests on public swimming pools: chlorine and bromine content, pH levels and cyanuric acid levels.
“If all f these chemistry measurements are within the approved levels, the pool should be able to disinfect waste as well as other bacteriological hazards that may pose a risk to swimmers,” Yanity said.
“I never heard of any water-borne illnesses around here that have actually been confirmed,” said Ryan Smith, crew chief at James Island County Park’s Splash Zone and a certified pool operator. “Actually, there is a lot of misinformation. In many cases people will say, ‘I got sick at the pool,’ but if the pool chemistry says no, facts are facts. It’s not possible.”
The funny thing is that the bacteria and parasites that actually thrive in the water, are usually put there by the swimmers themselves.
About one in five Americans admit to urinating in the pool, according to a 2012 survey conducted by the Water Quality and Health Council. And that’s the people who admit it.
“No amount of social shaming will make people stop peeing in pools,” said Sam Goodson, who operates a pool in Briarwood neighborhood near Columbia. “Even Olympic swimmers have admitted to it. Just imagine the number of people who do it and don’t admit it.”
Urine and fecal matter — plus sweat, sunscreen and other lotion — can all use up the chlorine that would otherwise kill germs in chemically treated pools, Goodson said.
When people swallow the water from the pool, they can get Recreational Water Illnesses, a wide variety of skin, ear, respiratory, eye and gastrointestinal infections. The most common RWI is diarrhea, which is caused by germs like E. coli and the parasite cryptosporidium.
In May, the CDC issued a press release warning that crypto outbreaks doubled in the United States between 2014 and 2016, from 16 to 32 cases.
Swallowing just a mouthful of water contaminated with crypto can make otherwise healthy people sick for up to three weeks with watery diarrhea, stomach cramps, nausea or vomiting, and can lead to dehydration.
“Just don’t do it,” Goodson said. “Keep your mouth closed. Don’t spit water on your friend. It’s not worth the risk.”
With the onset of warmer weather, the US Centers for Disease Control and Prevention (CDC) said today that reports of Cryptosporidium outbreaks linked to pools and waterparks are increasing.
There were twice as many outbreaks reported to CDC in 2016 compared with 2014, researchers from the CDC and from health department in Alabama, Arizona, and Ohio reported today in the latest issue of Morbidity and Mortality Weekly Report (MMWR).
Unique risks, unclear reasons
Crypto parasites, the most common cause of diarrhea and outbreaks linked to swimming pools or waterparks, aren’t easily killed by chlorine. Ingestion of pool water contaminated with feces from a symptomatic person can sicken healthy people with diarrhea, stomach cramps, nausea, or vomiting for as long as 3 weeks, according to the CDC.
In 2016, at least 32 Cryptosporidium outbreaks were reported to the CDC, compared with 16 in 2014. The CDC said it’s not clear if the number of outbreaks has increased or if better surveillance and lab testing has helped better detect outbreaks.
Michele Hlavsa, RN, MPH, said in the CDC press release, “To help protect your family and friends from Crypto and other diarrhea-causing germs, do not swim or let your kids swim if sick with diarrhea.” She also urged people to protect themselves by avoiding swallowing pool water.
State experiences, molecular tests help
In their report today the authors also detailed examples of recent large Crypto outbreaks in Alabama, Arizona, and Ohio. Arizona and Ohio reported steep increases for 2016.
In Arizona, an outbreak involving a Little League team and family members was traced to a July visit to an aquatic center, and Ohio’s report involved members of a college sports team who were part of a waterpark-related outbreak.
Alabama’s outbreak last year was tied to an aquatic facility that was in compliance with local standards, which the authors said shows how vulnerable facilities can be, even when properly operated.
The team also detailed how a relatively new molecular testing network, CryptoNet, is helping states detect and track outbreaks, as well as identify the types that are sickening people. For example, the researchers said Arizona health officials used the system last year to confirm a specific type of Cryptosporidium that spread to multiple swimming pools around Phoenix.

The idea that there are parasites living inside your body is very scary, but you are not alone. Parasites spread much wider than you think. The belief that only undeveloped countries’ citizens suffer from parasitic ailments is a myth.
Parasites are often found inside and on patients’ bodies. From this article you will find out that the presence of parasites is revealed by a large number of various symptoms, of which only a few involve digestion.
Though it is possible to determine the existence of parasites by the appearance of an individual, Gastrointestinal symptoms may reveal the most information. If you are afflicted by any of the following symptoms, it is necessary to consider parasitology treatment protocols.
There are a lot of symptoms indicative of parasites, but their presence can be considered as symptoms of other widespread diseases, therefore people often treat the wrong diseases. This is why experts recommend to begin the treatment of common diseases with a course of parasite cleanse.
Immune system impairment
Parasites weaken the immune system and lower production of protective immunoglobulins. Their presence opens the body to various infections and provokes dysbacteriosis.
Pain in joints and muscles
It is known that parasites can navigate the human body for settling in the most suitable places for their survival, such as in the synovial fluid and in the muscles. When this happens, a person experiences pain, which is often considered a consequence of arthritis. Pain and inflammation of the joints and muscles are also the result of tissue injury or immune reaction to worms presence.
Parasites can cause hives, rashes, eczema, and other skin reactions. Skin blemishes, tumors, sores, papillomas, and dermatitis may be the result of infections with parasites.
Acne, seborrhea, skin roughness, spots, early wrinkles on the face, early baldness, cracked heels, delamination, and brittle nails–all this may be byproducts of infections in the gastrointestinal tract.
Some worms attach themselves to the mucous membrane of the intestines and suck the nutrients from the host. While in the body in large numbers they may cause large enough blood loss (exanguation), resulting in iron deficiency, or anemia. Anemia is caused by worms like hook worms and protozoa that feed on the blood cells.
Abnormal weight can be a consequence of worms activity. Weight loss may disturbed digestion, reduced appetite, and the presence of “an internal consumer” of food.
Obesity as a result of tapeworms affection is not just excessive weight, but a protective reaction of an organism to the poisoning with waste products of parasites.
Abnormal metabolism and toxic substances of parasites irritate the central nervous system. Excessive anxiety, nervousness, and depression often are a consequence of systemic poisoning.
Teeth grinding during sleep (bruxism)
These symptoms are especially noticeable in sleeping children. Bruxism may be the response of nervous system poisoning and irritation.
Chronic fatigue syndrome
Symptoms of chronic fatigue include weakness, flu-like symptoms, apathy, depression, decrease in concentration, and poor memory. These physical, mental, and emotional symptoms arise because of nutrient deficiencies due to poor absorption of proteins, carbohydrates, fats, vitamins, and minerals.
Some worm infections deplete Vitamin B12 causing memory loss and compromised neurological functions. The broad fish tapeworm, Diphyllobothrium latum is known to cause such conditions.

Parasites – What are they and how do we study them? Parasitology is thе study оf раrаѕitеѕ, their hosts, thе rеlаtiоnѕhiр between thеm and human dеvеlорmеnt. Pаrаѕitоlоgу hаѕ еxроѕеd, and creates awareness аbоut thе growing раrаѕitiс diseases.
Whаt аrе раrаѕitеѕ?
Biоlоgiсаllу speaking, thе dictionary dеfinеѕ thеm аѕ “оrgаniѕmѕ that grow, fееd, and аrе ѕhеltеrеd оn or in a diffеrеnt organism whilе соntributing nothing to thе ѕurvivаl of thеir host.”
Thаt mild dеfinitiоn bеliеѕ the mуriаd diffiсultiеѕ thеу саn саuѕе thеir unwilling hоѕt. For еxаmрlе, dереnding оn thе type, thеу соuld рrоmоtе саtаrасt fоrmаtiоn duе tо раrаѕitе еggѕ dероѕitеd in thе lеnѕ or уоur еуе. Thеу саn саuѕе ovarian суѕtѕ in wоmеn. Thеу саn рrоduсе itсhу ѕkin оr ѕtrаngе rаѕh-ѕуmрtоmѕ thаt саn bе саuѕеd by раrаѕitеѕ thеmѕеlvеѕ, their eggs, or the tоxinѕ thеу release.
The Effect of Parasites
Hаving раrаѕitеѕ are a hiddеn cause of disease in the humаn bоdу. Pаrаѕitеѕ аrе оrgаniѕmѕ that livе on оr in a host bоdу. They fееd on thе hоѕt robbing thе hоѕt оf its nutriеntѕ. Ovеrwеight Pеорlе аrе likеlу tо bе infесtеd with раrаѕitеѕ, mаking it diffiсult tо gain оr lose weight. The раrаѕitеѕ tаkе аwау gооd nutriеntѕ frоm thе hоѕt leaving thе hоѕt with thе bad ѕtuff like the fаtѕ and ѕugаrѕ thus сrеаting intеnѕе hungеr or malnutrition in a hоѕt bоdу kеерing the parasite thriving while thе hоѕt is ѕiсk.
Pаrаѕitеѕ invade thе circulatory and lуmрhаtiс ѕуѕtеmѕ causing ѕwоllеn lymph nоdеѕ. Thеѕе toxins and bасtеriа invаdе your circulatory ѕуѕtеm саuѕing inflammation оf your jоintѕ that соuld bе misdiagnosed аѕ hаving аrthritiѕ. Pаrаѕitеѕ left untreated causes anemia, саrdiас сhеѕt pain (angina) and kidnеу dуѕfunсtiоn as wеll аѕ neurological dуѕfunсtiоn. Nеurоlоgiсаllу you mау experience confusion, muѕсlе wеаknеѕѕ, trеmоrѕ, оr ѕuddеn mоvеmеntѕ likе that оf Pаrkinѕоn’ѕ and paralysis.
Pаrаѕitiс disease саuѕе сhаngеѕ in your mood аnd behavior creating severe mental illnеѕѕ. You are irritable аnd aggressive with suppressed emotions likе соnсеrn, еxсitеmеnt, passion, mоtivаtiоn, оr nоt having аnу interest in ѕосiаl, emotional, or рhуѕiсаl lifе. A person infested with раrаѕitеѕ may lack a ѕеnѕе оf purpose in lifе or they mау fееl thеу dо nоt hаvе the ѕkill level to fасе a сhаllеngе and can take оn a hеlрlеѕѕ fееling.
Pаrаѕitеѕ аrе an еmbаrrаѕѕing diѕеаѕе tо have bесаuѕе it саn аffесt уоur social life. Thеу can саuѕе сhrоniс bасtеriаl or virаl infections leading tо ѕеxuаl dysfunction, mеnѕtruаl рrоblеmѕ, уеаѕt infections, mаlе impotency or urinary tract infections. Whеn infested with раrаѕitеѕ, the parasites lеаvе еxсrеmеnt in оr on уоur body сrеаting a toxic еnvirоnmеnt causing bоdу odor оr bad brеаth.
Pаrаѕitеѕ might create a vаguе achiness, оr muѕсlе aches оr twitches (duе to larvae that hаvе invаdеd muscle ѕtriаtiоnѕ). Thеу can triggеr hot flаѕh activity in wоmеn, аnd рrоѕtаtе ѕwеlling in men.
Parasites саn сrеаtе digеѕtivе ѕуѕtеm ѕуmрtоmѕ ѕuсh аѕ gаѕ, bloating, аnd belching, vаguе nаuѕеа, loss оf appetite оr ѕtrаngе сrаvingѕ. They can stimulate increased sweating. Thеу саn create trоublе swallowing, оr еvеn diffiсultу brеаthing duе tо lаrvае in thоѕе muѕсlеѕ. They саn еvеn mimic ѕуmрtоmѕ оf some аwful dеbilitаting disease such аѕ luрuѕ or multiple ѕсlеrоѕiѕ. Thе ѕуmрtоmѕ оf this disease might resolve еntirеlу once thе раrаѕitеѕ аrе cleared.

What shoots our immune system into fighting mode when a parasitic infection exists in the gut? New research discovers that specialised cells known as tuft cells have an important role—by “tasting” the existence of intestinal parasites and putting our immune system into motion, fighting against them.
The study, mentioned in an article published on the 2nd of February 2016 in Science, is vital, said senior author Wendy Garrett, Melvin J. and Geraldine L. Glimcher. Having more knowledge about the interaction between tuft cells and our immune system might help scientists around the world come up with new ways to treat diseases caused by parasites such as roundworm, giardiasis and hookworm, which affect several of people worldwide— especially children—which cause symptoms such as nausea , diarrhea, bloating, vomiting and pain, and could also contribute to weight loss as well as malnutrition.
Scientists already have a good background tuft cells, which have firm bristles and branch out from the intestinal wall in batches, since the mid-1950s. But until recently their job has been vague.
Garrett’s study gave new information on tuft cells. “It’s pretty cool that three groups revealed different information about these cells at the same time, by coincidence,” she said. “We all found that tuft cells have a crucial role in our immune system.”
Garrett’s research lab focuses on the interaction between our gastrointestinal immune system and the microbes and parasites that thrive in the gut in health, inflammatory bowel disease, and colorectal cancer. Her team demonstrated that eventhough tuft cells don’t really “taste” things, they use a process known as “taste chemosensation.” This is very similar to the process by which our tongue taste buds spot different flavors. In the gut, such a process permits tuft cells to detect various parasites such as helminths (worms) and protozoa, and to then send out signals to other cells to start an immune response.
The researchers were able to locate tuft cells’ function by relating two groups of mice infected with parasites. The mice in one group did not have key proteins that tuft cells utilise to send messages to other cells. Five weeks later, the mice that lacked the protein had additional worms than the other mice. The normal mice also created extra tuft cells and had higher levels of a protein which triggers immune responses to parasites (interleukin-25).
Infections which are usually caused by helminthes as well as protozoa are usually treated with antiparasitic medicines. The new finding however could help lead to alternative treatments, Garrett mentioned. “If we can have a good understanding out how to engage ‘taste chemosensation’ in tuft cells—in principle, to understand what the parasites are generating that tuft cells ‘taste’—there is a chance we could help improve the immune system,” she mentioned.
Garrett also said that she is enthusiastic about the implications of their new results. “That parasite-derived molecules can actually be tasted—and that tuft cells in the gut do this—gives us new perspective about how our organisms interact with the microbes in our world,” she mentioned.
