There are different ways to infect humans with parasites.Statistics say that a common cause of human death is the presence of parasites in the body and infectious diseases.
Scientists have found fungi, bacteria and even algae in blood plasma.The most common are intestinal helminths.
Parasites can live inside a person for a long time.In 60% of cases, chronic and oncological diseases are caused by their vital activity.With prolonged exposure to microorganisms, internal organs and the entire immune system suffer.
Parasite infection methods
Parasite infection methods are different.Parasites are microorganisms that live at the expense of another organism and are related to it biologically and ecologically.Parasites can feed on juices, tissues and foods that a person consumes, remaining in the body temporarily or permanently.
You can become infected with helminths in the following ways:
- Through dirty hands.
- Upon contact with the ground.
- For insect bites.
- If you eat an undercooked piece of meat or fish.
- If you don't wash fruits and vegetables before eating.
- If you have illiterate contact with animals.
- When contacting a person sick with helminths.
Worm eggs can be found in soil, water, dirty fruits and vegetables, as well as meat or fish that have not undergone sufficient heat treatment.
In some cases, infection can occur due to an insect bite, but this is extremely rare, since helminth eggs enter the body mainly with food.Dirty hands can also become a source of helminthiasis infection.
You can also become infected from a sick person who carries worms.The pinworm crawls through the anus and lays its eggs in the anus.They, in turn, can remain on underwear, ending up in a person's hands.Larvae can remain in the toilet bowl, on the front door handle and on other objects.If personal hygiene rules are not followed, they penetrate the bodies of other family members.If helminths are found in one of the family members, all family members must undergo treatment.
Waterborne infection occurs through consumption of unboiled water or while swimming.
What types of helminths are there?
The most common group of intestinal worms includes nematodes.These include hookworms, roundworms, pinworms, heartworms, and trichinella.
The second large group includes protozoa or single-celled parasites.These are amoebas, lamblia, neospores, cryptosporidium, etc.
Entamoeba histolytica infection can occur through ingestion of dirty water.In this case, loose stools appear, severe abdominal pain and vomiting occur.Sometimes, in severe cases, such manifestations cause liver complications.People often confuse amoebic dysentery infection with a viral infection.
Millions of single-celled parasites can exist and develop in the walls of the stomach, which prevent the nutrients needed by the body from being absorbed properly.
Characteristic signs of giardiasis
The symptoms of parasitic infestation are as follows:
- Accumulation of gases in the stomach.
- Lumpy stools with pieces of undigested food.
- Chills.
- Increased sweating.
- Frequent abdominal pain.
- Loose stools.
In the absence of treatment for parasites, over time, a person will begin to lose weight and often become ill due to a depleted immune system.Of course, it is not advisable to be guided by symptoms alone to identify parasites.It is necessary to carry out a series of fecal and blood tests to detect helminths.Treatment largely depends on the degree of infection.In folk medicine there are many recipes for the treatment of helminthiasis;In difficult cases it is better to resort to medication.
Helminth classification
Worms are divided into flat and round.
Plan views:
- Trematodes, including schistosomes, opisthorchis, etc.
- Cestodes - echinococci, pork tapeworm, alveococci.
Roundworms or nematodes:
- Pinworm.
- Ascaris.
- Trichinella.
- Hookworm.
The most common types of helminths are:
Schistosomes
This type of worm is of different sexes;in appearance it resembles a needle with a length of 0.4 to 2.6 cm.Females are considered large and can produce up to 300 larvae per day.
The route of transmission is mainly through swimming in polluted waters.Infection occurs through human mucous membranes and from accidental ingestion of dirty water while bathing.Once in the body, the larva turns into an adult in a day, capable of producing hundreds of similar organisms.
The schistosome reaches sexual maturity after entering the human venous system through the bloodstream.Individual eggs can be in the intestines, urine and mucous membranes.After defecation, the schistosome begins its journey in the same way.
This parasite can remain in the human body for decades, causing irreparable damage to the patient.It is not the schistosomes themselves that are dangerous, but their eggs.They accumulate in internal organs and with their thorns they cause damage, damaging tissues, which often causes various ulcers.
There are symptoms by which a person can determine the presence of schistosomes in the body:
- lack of appetite;
- anemia;
- enlarged liver and changes in the spleen;
- poor intestinal motility;
- stomach pain;
- diarrhea or constipation;
- sudden weight loss;
- bleeding in the intestines;
- pain when urinating;
- allergic reactions;
- general weakness.
Cestodes
Cestodes are tapeworms that can reach gigantic lengths.Thus, the length of an adult is on average 0.5 cm.A female cestode is capable of laying up to 200,000 eggs over the course of a year.
Thanks to special devices on the heads in the form of suction cups, the cestodes are firmly attached to the intestinal walls.In this case, the whole body suffers.These worms are especially dangerous for young children, as their vital activity depletes the body and causes anemia in a short time.
The routes of infection are fecal-oral, that is, dirty hands, fruits and vegetables.The larvae, once in the intestine, spread through the veins throughout the body, penetrating the liver, heart and even the oral cavity.A certain number of larvae die, while the rest are swallowed again.
The main signs of parasitic infestation:
- nausea and vomiting;
- yellowing of the skin;
- pancreatitis;
- frequent colds;
- development of bronchitis and pneumonia.
Parasite infestation prevention
As there are many forms of parasite infection, it is worth following some rules to protect yourself and your family members from possible ingestion of worm larvae.
- Compliance with personal hygiene rules.Frequent hand washing will prevent parasites from entering the human body.Children especially need to learn this, as they often put their hands and various objects in their mouths.
- Thoroughly wash fruits and vegetables with running or boiled water.
- Extermination of flying and crawling insects (flies, cockroaches) in residential areas, as they carry helminth eggs.
Many experts believe that every person, in one way or another, is a carrier of parasites, so it is necessary to cleanse the body from time to time.
