Parasites scary, dirty or even dangerous?

Most people are not crazy about parasites, because parasite is often used as a swear word. But is the parasite just scary, dirty and annoying or is the parasite also dangerous?

What is a parasite?

A parasite is a tiny little animal that lives at the expense of another’s life. That sounds cruel, but a parasite cannot live without a host or female. In addition to all kinds of single-celled organisms, there are such known ones as:

  • mite
  • Luis
  • Mosquito
  • Flea
  • Tick
  • Worm

The life cycle per animal is different, for example, a flea can survive 5 to 6 months without blood, a louse can survive 1.5 to a maximum of 2 months without blood. And if we think this is a long time, there are mosquito species that can live for years without a blood donor. Getting rid of parasites does not apply to every parasite.

Are parasites dangerous?

One of the best known and probably most dangerous is the malaria mosquito. It transmits malaria from person to person via the mosquito bite. But more viruses and bacteria can enter our bodies through the bloodstream. Yellow fever or Lyme disease can also be transmitted (via the tick).

But not all parasites are dangerous. For example, a parasite is also responsible for toxoplasmosis, but a healthy person will not be affected by this. If you have a strongly reduced resistance, such as AIDS patients, you can die from this. This also applies to the vulnerable unborn child, which can be dangerous.

Is there anything to do if you are infected?

In general, if you catch it in time, it can be treated easily. The difficult thing is that you do not always know it immediately and the disease can creep into your body like a creeper at night. Furthermore, the first symptoms are often flu-like and you have to be very alert to identify the true cause. Almost every child in primary school has to deal with lice and although it is a tough job, the lice can be expelled, as many parents will know.

Can it be prevented?

With the right precautions you can go a long way. Vaccination is essential for some countries where the chance of encountering the malaria mosquito, for example, is very high. But make sure you always eat your food immediately after cooking, baking or defrosting and eat fruit that you peel yourself.

Where do all those parasites come from?

One of the main reasons is globalization. It goes without saying that since people travel the world, they also bring easy diseases with them. You take the parasite with you relatively unnoticed and you may only discover it in your home country at some point. It goes without saying that you could already have infected people around you.

And since the parasite is carried by humans, it does not matter where it lives, as long as it is a warm-blooded body. This is in contrast to animals that live in Africa, for example, and could not even survive here because of the weather. The parasites that face a very harsh winter and are outside a body may have problems surviving.

Only bad?

With the exception of one case, yes. For example, people with Crohn’s disease may benefit from the eggs settling in the intestinal wall. The immune system will then work like crazy to remove the eggs and will not focus on what is particularly bothering you, the inflammation in the intestine.


We do not get much pleasure from the parasite, but we can defy the parasite by taking the known precautions and, once the suffering has been suffered, treating it properly as quickly as possible.
