What are you eating? 8 parasites that live in humans

Parasites are organisms, often worms, that enter the body of another creature to feed on it, literally devouring it from within. Their infection is dangerous to health and sometimes life. The most disgusting parasites in the human body are described below.

Loaloa eye worm

Eye worm

The habitat of this parasitic roundworm is Central and West Africa. The vectors are flies and mosquitoes. Through insect bites, the larvae enter the body of humans, as well as primates or rodents. They live in the fatty tissue of the host, reaching 4-7 cm.

The Loa loa worm travels under the skin, sometimes crawling to the eyeball - under the conjunctiva. The disease it causes is called loiasis. In severe cases, the parasite infestation leads to blindness.

Human fly

This unpleasant species of insects does not live on the territory of Russia, but there are many human flies in Central and South America. The most unusual thing is the way they reproduce. The insect catches a mosquito and lays eggs in its stomach, then releases it into the wild. Such a "package" often finds its owner.

The warmth of the blood sucked in by the mosquito helps the larvae gain strength. They then enter human skin through a new mosquito bite or through a hair follicle. The parasite begins to feed, causing severe itching and stabbing pain. The best way to get it out is to limit the oxygen supply, for example with oil or petroleum jelly.

Fish tapeworm - tapeworm

Parasites enter the intestines through undercooked food, for example food that has not been cooked.

Tapeworm eggs are ingested by humans from fish and seafood. By itself, it is not too dangerous, but it sucks vitamin B12 from the host body, without leaving the goodquantity to the person. It is also unpleasant that he reaches 7 m.

Currently tapeworm infections are relatively rare. Experts believe that with the growing popularity of sushi and rolls, this intestinal parasite will become a more common problem.

Pork tapeworm

Pork tapeworm

The tapeworm grows up to 3 m. Pork tapeworm infects humans from undercooked pork. For the sharp hooks on his head (scolex) he was nicknamed "armed": with the help of them and suction cups, he is retained in the body of the host, most often in the intestines.

When the parasite's life cycle comes to an end, it throws out the eggs that enter the environment with the host's feces. Pork tapeworm causes a dangerous tapeworm disease. In Russia, it is widespread everywhere, especially in areas where pig farming is developed.

Lice and bedbugs

These parasites do not penetrate humans, but are known for their painful and itchy bites. Lice live on hairy areas of the body, mainly on the head. The disease they cause most often is head lice in children. Getting rid of them is relatively simple: you need to cut your hair and rinse your skin with special shampoos or formulations. Preventive measures should also be taken by relatives of the infected person living with him.

Bed bugs are more dangerous. Parasites live in mattresses, sofas, bedding, curtains, clothing, and even books. It is extremely difficult to get rid of it. Lice and bedbugs are also dangerous because they are carriers of serious diseases - from smallpox to influenza.

Guinean verses

Parasites live in countries in Asia, the Middle East and Africa. They cause the disease of dracunculiasis. Despite their small size, worms cause severe pain. The parasite enters the host's body through contaminated drinking water. The larvae mature in the stomach and multiply in the intestines.

The adults migrate to the surface of the skin, where they grow up to a meter These worms have a rich history: their traces were found in Egyptian mummies. Possible references to them are found even in the Holy Scriptures.

Plasmodium Parasites

These single-celled organisms cause the dangerous disease of malaria. It is spread by infected mosquitoes. Up to 500 million people fall victim to malaria each year. Symptoms of infection are fever, headache, vomiting. In the most severe cases, these parasites cause the death of the host because they block the flow of blood to internal organs.

Human parasites of the genus Trypanosomacruzi

Human parasites of the genus Trypanosomacruzi

American trypanosomiasis, or Chagas disease, is caused by triatomine bugs found in poor areas of Central and South America. The bug is also called a "kissing bug" or "affectionate killer".

The disease is transmitted by bites, blood transfusions, contaminated food, from mother to fetus. Symptoms gradually worsen and include fever, swollen lymph nodes, headache and, in severe cases, heart failure.
