There are different ways to infect humans with parasites.Statistics say that a common cause of death for people 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 life activity.With prolonged exposure to microorganisms, internal organs and the entire immune system suffer.
Methods of parasite infection
The methods of infection with parasites 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 sap, tissue and food that a person consumes, remaining in the body temporarily or permanently.
You can get infected with helminths in the following ways:
- Through dirty hands.
- In contact with the ground.
- In insect bites.
- If you eat an undercooked piece of meat or fish.
- If you don't wash your fruits and vegetables before eating.
- If you have illiterate contact with animals.
- In contact with a person sick with helminths.
The eggs of the worms can be found in soil, water, dirty fruits and vegetables, as well as in meat or fish that have not undergone sufficient heat treatment.
In some cases, infection can occur due to an insect bite, but it 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 get infected from a sick person who is a carrier of shingles.Pinworms crawl through the anus and lay their eggs in the anus.These, in turn, can remain on the underwear, ending up on a person's hands.Larvae can remain on the toilet, doorknob and other objects.If the rules of personal hygiene are not followed, they penetrate the body of other family members.If helminths are found in one of the family members, all family members should undergo treatment.
Waterborne infection occurs through consumption of unboiled water or swimming.
What types of helminths are there?
The most common group of intestinal worms includes nematodes.These include hookworms, roundworms, pinworms, heartworm and trichinella.
The second large group includes protozoan or unicellular parasites.These are amoebae, lamblia, neospores, cryptosporidia, etc.
Entamoeba histolytica infection can occur by drinking dirty water.In this case, rare stools, severe abdominal pain and vomiting appear.Sometimes, in severe cases, such manifestations cause complications in the liver.People often confuse an amoebic dysentery infection with a viral infection.
Millions of single-celled parasites can exist and thrive on the walls of the stomach, interfering with the proper absorption of nutrients needed by the body.
Characteristic signs of giardiasis
Symptoms of parasite infestation are as follows:
- Accumulation of gas in the stomach.
- Loose stool with pieces of undigested food.
- Shivering.
- 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 sick due to the depletion of the immune system.Of course, it is not advisable to be guided only by the symptoms to identify the parasites.It is necessary to conduct a series of stool and blood tests to detect helminths.Treatment largely depends on the extent of the infection.In folk medicine there are many recipes for the treatment of helminthiasis;in difficult cases it is better to resort to medicines.
Classification of helminths
Worms are divided into flat and round.
Flat views:
- Trematodes, these include schistosomes, opisthorchis, etc.
- Cestodes - echinococcus, pig tapeworm, alveococcus.
Roundworms or nematodes:
- Pinworm.
- Ascaris.
- Trichinella.
- Hookworm.
The most common types of helminths are:
schistosomes
This kind of worm is of a different sex;looks like 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 contaminated waters.Infection occurs through human mucous membranes and by accidental ingestion of dirty water during bathing.Once inside the body, the larva turns into an adult within a day, capable of producing hundreds of similar organisms.
Schistosoma reaches sexual maturity after entering the human venous system via 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 harm to the patient.It is not the schistosomes themselves that are dangerous, but their eggs.They accumulate on the internal organs and with their spines cause damage, damage the tissue, which often causes various ulcers.
There are symptoms by which a person can determine the presence of schistosomes in the body:
- poor appetite;
- anemia;
- enlarged liver and changes in the spleen;
- poor intestinal motility;
- stomach pains;
- 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.One female cestode is able to lay up to 200 thousand eggs in one year.
Thanks to special devices on the heads in the form of suction cups, cestodes are tightly attached to the walls of the intestine.In this case, the whole body suffers.Such worms are especially dangerous for small children, because their vital activity exhausts the body and causes anemia in a short time.
The routes of infection are fecal-oral, i.e.it's dirty hands, fruits and vegetables.Larvae, having entered the intestine, spread through the veins throughout the body, penetrating the liver, heart and even the oral cavity.A certain number of larvae die and the rest are swallowed again.
The main signs of parasite infestation:
- nausea and vomiting;
- yellowing of the skin;
- pancreatitis;
- frequent colds;
- development of bronchitis and pneumonia.
Prevention of parasite infestation
Since there are many ways to become infected with parasites, it is worth following some rules to protect yourself and family members from possible ingestion of worm larvae.
- Compliance with the rules of personal hygiene.Frequent hand washing will prevent parasites from entering the human body.Especially children need to be taught this, as they often put their hands and various objects in their mouths.
- Thorough washing of fruits and vegetables with running or boiled water.
- Destruction of flying and crawling insects (flies, cockroaches) in residential premises, as they are carriers of helminth eggs.
Many experts believe that every person to one degree or another is a carrier of parasites, so it is necessary to clean the body from time to time.
