How do parasites enter the human body?

Everyone is very afraid of parasites because they can cause a variety of diseases after entering the human body. Parasites are most likely to appear in the human intestines, causing abdominal pain, diarrhea and many other symptoms. Severe cases can also cause anemia, itchy skin, fever, etc. Therefore, it is important to take measures to prevent parasites in daily life. To this end, we must understand the ways in which parasites enter the human body so that we can achieve targeted prevention.

How do parasites enter the human body?

1. Oral infection. If you ingest water or food contaminated with infectious ascarid eggs or amoebic cysts, you may be infected with ascariasis or amebiasis.

2. Transmitted by blood-sucking insects. If you are bitten by an Anopheles mosquito infected with Plasmodium, you may get malaria.

3. Infection through the skin. For example, the filariform larvae of hookworms can directly penetrate the host's skin and infect it.

4. Transplacental infection. Such as congenital malaria, congenital toxoplasmosis, etc.

5. Infection through the respiratory tract. For example, primary amoebic meningoencephalitis is infected through the nasal mucosa.

6. Other methods. For example, blood transfusion can cause infection with malaria parasites.

Although there are six transmission routes for parasitic diseases, infection does not necessarily lead to illness. The onset of illness mainly depends on the number and virulence of the parasites that invade the body and the host's immunity. The more insects that infiltrate and the stronger their virulence, the greater the chance of disease and the more serious the condition.

The treatment of parasitic diseases focuses on eliminating parasites, and the most effective anthelmintic is used according to the species of parasites. When the infection is severe and the host is weak, supportive therapy can be given, and surgical treatment should be performed promptly if there are surgical complications.

There are many factors that cause human parasites to develop. Unclean diet and weak physical constitution are the main factors that lead to parasitic diseases. Therefore, you must pay attention to dietary hygiene and try to cook the food as much as possible.

To prevent diseases, you must first understand parasitic diseases. Parasitic diseases are diseases caused by some parasites that live in the bodies of humans and animals.
