What Are the Causes of Parasitosis

Parasitosis, or parasitic disease, is an infectious disease caused by parasites such as worms, solitary or amoebas. Therefore it does not fall into this classification with those infections caused by fungi, bacteria and viruses. A parasitic disease can be contracted through contaminated items, making parasites enter and adhere to our gut.

This disease causes many deaths each year worldwide, so we have to exercise caution and have good hygienic habits in our daily lives to prevent its spread. To know what are the causes of parasitosis, carefully read this OneHowTo article.

Steps to follow:

Parasitosis is transmitted through contact with infected items - for instance, eating contaminated food. Eating at street stalls where there is no strict food safety may be a risk to your health, which favors the transmission of this condition as well as other gastric diseases. Therefore, if health standards don't seem to be enforced, it is recommended not to do so.

The safest thing to do is to eat food in restaurants or premises where we know that food safety measures are in place, especially when we consume raw or delicate foods such as fresh vegetables, raw fish, unprepared meat, etc.


Contaminated water can be another route of transmission for this disease, so it is recommended you drink bottled water, especially when travelling if you do not know where it comes from and whether it is clean.

When sold in bags, ice is not reliable as we are still at the risk of parasitosis, because often it is not made with purified water. We must not consume it outside our home if we are not sure that it complies with the appropriate regulations.

The soil is highly polluting and suitable for the transmission of parasites. Animals with parasitic infections can defecate in soils cultivated with fruit and vegetables that may subsequently come to our table, meaning we run the risk of contracting parasites.

We must know at all times where these foods come from before eating. Always wash them thoroughly with water and white vinegar in order to eliminate any possible infectious organisms.

Insects are one of the main carriers of parasitic diseases, as their bite causes this infection quickly and widely.

It is important that if you live in an environment where there are a lot of insects you take appropriate measures to avoid bites. The use of mosquito nets and repellents for both home and the body is essential in these cases. In our article how to make homemade mosquito repellent, we offer several alternatives to combat them.

Sexual intercourse is also one of the causes of parasitosis, as we are in close or direct contact with the anus, where our feces can be infected and lead to infection.

Always be protected with condoms and take special care with the practice of oral and anal sex. In both cases, care for your hygiene and especially avoid contact of possible traces of fecal matter in other areas of the body such as the mouth or vaginal area.


The symptoms of parasitosis can be confused with other diseases that are milder in character, so we have to pay attention to the possibility of having contracted parasites by any of the above means. The most common signs of this condition are:

  • Generally feeling unwell.
  • Dizziness and nausea.
  • Diarrhea and constipation.
  • Lack of appetite.
  • Abdominal inflammation.

The consequences of a parasitic disease can become very serious, as parasites can obstruct the gut or cause painful ulcers. Sometimes these factors lead to death, but it can lead to other complications such as liver failure or brain damage for which there is no remedy.

To prevent this disease, we have to resort to good hygiene before eating and after using the bathroom, as well as cooking meats for consumption and disinfecting vegetables and fruits that we plan to eat. Thus we avoid the transmission of intestinal parasites that can be carried by animals and humans.
