Do you know what parasites are in the human body?

Amoeba coli, the most common commensal protozoa in humans, is generally not pathogenic. The infection rate of parasites is high. But you have to understand that parasites are not bacteria, and parasites are harmful as long as they are infected.

The parasites we talk about, especially those mentioned in medical parasitology books, are often pathogenic. Although the presence of parasites in the body is not necessarily symptomatic, the presence of parasites in the body is generally not considered a sign of health in medicine. Of course, people still often deal with parasites such as amoebas or trichomoniasis.

Many of the world's poor developing countries and regions have poor sanitation in economically backward places, such as rural areas, and many people may have parasites. Parasites on the body, such as mites, are indeed very, very common, regardless of urban or rural areas and where they live, and they may be common to everyone, but it can also be an allergen. To the best of my knowledge, there is no significant health benefit to the presence of mites.

If you are an adult, if you add up all the parasites, you can count on it. There are three major infection rates: the mite infection rate is more than 50%, the intestinal parasite is 2 billion in the world, the infection rate is 1 3, and the infection rate of Toxoplasma gondii is 25% to 50%.

Just looking at these 3, most of them have already been recruited. If you don't count the mites, which are parasitic on the sebaceous glands of hair follicles (the body surface should not be counted in the body) and have no lethality, if you count the rest, it is estimated that half of the population is calculated. If it is limited to China's cities (developed areas), it is to exclude intestinal parasites, leaving only Toxoplasma gondii, liver flukes and trichomoniasis, which is estimated to be 10%, which is still a bit big with "everyone".

Here are some common parasites and their approximate incidence: malaria, schistosomiasis, and intestinal parasites are endemic in developing countries in Asia, Africa and Latin America. Toxoplasma gondii, mites, pubic lice, head lice, trichomoniasis are endemic worldwide.

The symptoms of parasite infection in humans are as follows:

1. Systemic symptoms: The most common systemic symptom is fever, and there may be fever of varying degrees, such as low-grade fever, high fever, no fever, etc.;

2. Local symptoms: depending on the parasitic location of the parasite, 1. Brain, symptoms such as headache, dizziness, blindness, and limited movement of limbs may occur. 2. Lungs:

Symptoms such as cough, sputum production, blood in sputum, chest tightness, panting, exertion, and breathlessness may occur. 3. Liver: It may cause liver function to be impaired, such as liver discomfort, liver swelling, loss of appetite, etc.

Because after the liver function is impaired, it may affect the function of the digestive tract and cause indigestion. 4. Intestinal discomfort, constipation, diarrhea, worms in the stool, etc. For example, the common intestinal roundworm sometimes appears after the lesion will show the symptoms of carrying worms in the stool.

<>1. Human parasites refer to parasites that use humans as hosts. It can be divided into two categories: internal parasites and external parasites. Most of them belong to protozoa, nematozoa, flattened animals, annelids, and arthropods.

In parasitology, protozoa are commonly referred to as protozoa, and nematozoa and flattened animals are collectively referred to as helminthes. Most of the important species of internal parasites include protozoa, nematodes, flukes, and tapeworms.

2. Parasites are eaten. Some larval cysts are also found in the lungs, under the skin, and even in the brain, eyes. Parasites are harmful to the human body, and the damage to the human body is mostly to prey on nutrients, cause inflammation, block blood vessels, etc.

Most of them belong to protozoa, nematozoa, flattened animals, annelids, and arthropods. In parasitic orthostomology, protozoa are commonly referred to as protozoa, and nematozoa and flattened animals are collectively referred to as helminthes. Most of the important species of endoparasites include protozoa, nematodes, flukes, and tapeworms.
