A 9 year old boy is almost blind from a parasite in his right eye, how harmful is the parasite?

As a living organism, parasites have the following two main hazards.

One is that it has the hazard of transmitting pathogens as living organisms.

The second is that it itself has the effect of being a pathogen.

Parasites are generally smaller in size and smaller than the host itself. The vast majority of parasites are harmful to the host. The host can be a human or another type of animal.

For example, in the creature of the praying mantis, almost every individual has a nematode parasite. This parasite is at the time when the praying mantis survives. It will gradually eat all kinds of internal organs in the body of the empty mantis.

And through the passaging behavior of the praying mantis. Gradually expand to the entire population of praying mantises. In the process, the praying mantis will gradually die.

The nematode then lays eggs and looks for its next host.

There are also very few organisms that have a symbiotic relationship with their host. But they are generally not insects. Diseases caused by parasites include but are not limited to anemia, external bleeding, trauma, internal bleeding, wounds that are difficult to heal, diarrhea, high fever, etc.

Severe cases can even lead to human death. Parasites are transmitted in a similar way to many diseases. The difference is that there are usually a lot of people when they are exercising outdoors.

A place with a high concentration of parasites was chosen. Such as the river side in the wild. Or on the beach with poor hygiene, or the family has a pet first, but is not diligent in cleaning and not vaccinated on time.

These can lead to a certain chance of contracting the parasite.

The little boy in this question is an eye disease caused by infection with the Toxocara parasite. Diseases caused by parasites are generally similar to many diseases due to their characteristics. And the symptoms are usually not severe.

So unless the patient has a clear statement. Or the patient has significant parasitic symptoms. Otherwise, it is usually difficult for medical exams to notice these tiny pests.

Children in particular are at an active age. Moreover, it is more tender and easy to be broken by various reasons. Parasites in the environment can enter the human body through these wounds.

Usually children have less resistance. It is not possible to kill these parasites in time. This will lead to the reproduction and development of parasites.

Symptoms then develop.

Parasites can eat a lot of human tissue, killing people. So parasites are the ones that kill humans, super scary.

The harm of parasites is great, because it reproduces quickly, so once there are parasites in the body, the consequences are unimaginable.

Parasites are symbiotic organisms for humans, but parasites will flow in the body with some substances such as blood or multiply everywhere, so they are still very harmful to the human body.

A 9-year-old boy who was almost blind from a parasite in his right eye attracted everyone's attention after the news aired on the Internet.

According to the family, the little boy is 9 years old this year, and the family often finds that he has the habit of rubbing his eyes, and they didn't care about it at the time, but just took the little boy to the hospital for a simple examination.

The boy's parents told the doctor that the boy had been studying online at home during the epidemic, and because his parents were not often at home, the boy secretly watched TV and played with his mobile phone. At the end of August, when everyone was talking about the child's myopia, the little boy suddenly said: "I can't see in my right eye" At that time, the parents thought that the little boy was just joking, but they still sent him to the hospital for a detailed examination, but the results of the examination surprised the parents, and the doctor told the parents:

The little boy's right eye, you can barely see clearly.

Many parents think that their child's vision loss may be related to watching TV or playing with mobile phones for a long time, but after a preliminary examination of the boy's right eye, the doctor came to the conclusion that the boy's right eye was caused by a parasite burrowing in, and the reason for this may be related to animals.

The doctor asked the little boy's parents whether they had animals at home, and the little boy's parents said that the neighbor's house did have a puppy in their house during the winter vacation this year, and the little boy was very fond of animals and often held the puppy to play, and the doctor said that the cause of the little boy's blindness in his right eye may be caused by frequent contact with small animals that caused toxocaris infection. The doctor explained:

The rate of toxocaria infection in animals is very high, and if you come into contact with these small animals regularly and eat without washing your hands, there is an increased risk of infection.

Fortunately, the boy's condition was detected early, and after the operation, he was discharged from the hospital to recuperate, and during the last follow-up, the doctor found that his vision in his right eye had basically returned to normal. Here, the doctor reminds everyone: there are many parasites on animals, if there are animals at home, the animals must be dewormed, disinfected in time after contact, and the animal's feces should be treated in time.

They generally do not pay attention to hygiene or have close contact with infected animals. Parasitic infections are usually transmitted through other infected organisms, which are easy to become infected by contact with these sources of infection.

Because he always uses electronic products for a long time, his eyes are tired, and he doesn't pay attention to eye hygiene, and when his eyes are itchy, he likes to rub his eyes with his hands.

Qiang Qiang has a pet puppy at home, so his eyes are likely to be low vision caused by Toxocaris infection in his pet, and his eyes appear black.

The results were not very good, because it was too late, so the right eye was still close to blindness.

After knowing that the boy could not see in his right eye, the parents also rushed to send the child to Hangzhou for treatment, fortunately, there was not much damage to the macular area of the right eye, and after surgery, most of the vision could be slowly restored.

The Shaoxing boy was almost blind due to a parasite in his right eye, and after the doctor examined him, he was then operated on, and now the boy has returned to normal school life, and his vision in his right eye has basically recovered.

The Shaoxing boy was almost blind after a parasite in his right eye, but his vision in his right eye has been restored, and he was discharged from the hospital and went home for a normal school life.

The boy had a parasite in his right eye, which he had caused from having a pet at home. He has pets at home, and he spends a lot of time with them. Then I reported that the pet rubbed his eyes directly without washing his hands, causing bacteria to enter.

He didn't pay attention to hand hygiene, and he ended up rubbing his eyes, which led to an eye infection.

Qiang Qiang has pets at home, and he often likes to play with this dog, so it caused Toxocaris infection.

When he went to an unclean water source, he contracted a parasitic disease, and in this way the parasite grew in his body, which seriously affected himself.

If the eye is infected with parasites, the first thing that comes to mind is the infection caused by rubbing the eyes with your hands, because there is a high chance of infection in the hands and eyes.
