Cough in children as a result of helminthic invasion is quite common, but it can be mistaken for a cold. Therefore, before starting treatment, it is better to carefully examine the body in order to identify the causes of the symptom. Its appearance signals the presence of some abnormal process. A cough with worms indicates that there is intense movement and reproduction of helminths in the body. We will now deal with the question of which parasites cause coughing.

How coughs and worms are related

Many people have a question: can worms cause a cough, because, at first glance, they are in no way associated with this symptom? But quite often diseases that develop as a result of parasitizing helminths lead to the appearance of just such a symptom.

Its appearance can be explained by the fact that:

  1. In one case, the parasites can lodge in the lungs.
  2. In another appearance, the movement of helminth larvae along the internal organs of the respiratory system can contribute.

When the worms are localized in the bronchial tree, they obstruct the air flow, resulting in a dry cough. At first glance, it seems that it is without any secretions, but in fact, with a cough, a significant number of eggs and larvae enter the environment, which cannot be seen with the naked eye.

Parasites can also lead to the formation of inflammatory processes in the tissues of the vessels located in the respiratory organs, and this will also contribute to the appearance of a cough. But with it, the products of the inflammatory reaction will already enter the surrounding space.


The most severe manifestations of cough will be, the cause of which is considered to be a disease (caused by parasites) such as paragonimiasis. Such a cough is evidence that the helminths are located in the lung cavity, disrupting their normal functioning.

Types of parasites that lead to coughing

A cough caused by parasitism of helminths can appear in two ways:

As a result of migration from the intestine. Such worms include ascaris and lamblia. The favorite place of localization of these parasites is the intestine. But starting to multiply actively, the larvae gain the ability to enter the circulatory system. As a result, with the blood flow, they enter the trachea, bronchi and lungs

With this migration, the larvae actively consume blood components and secretions of mucous membranes, producing toxic substances. And this, in turn, leads to the appearance of allergies and inflammatory reactions.


Worms, which are immediately localized in the lungs, are considered the most dangerous, because they have the ability to cause severe lung diseases. Such helminths are considered toxocar and pulmonary fluke. It is these parasites that cause diseases that are called toxocariasis and paragonimiasis. Their course leads to the destruction of lung cells and their malfunctioning. The main manifestation of these diseases is cough. With the progression of pathological conditions, it can be accompanied by the release of sputum and even with blood impurities

Influence of Ascaris

If a cough as a result of parasitizing helminths appears in children, then in most cases this indicates the migration of ascaris. This helminth can reach sizes up to fifteen centimeters. Infection occurs:

  • as a result of contact with infected pets;
  • if the rules of personal hygiene are not followed;
  • when eating unwashed vegetables.

The reason that ascariasis develops in children is believed to be that their body is not yet sufficiently formed, as well as the fact that children, without adult supervision, do not always follow hygiene.

As already noted, roundworms are localized in the intestines. Their intensive reproduction leads to disruption of metabolic processes and the release of toxic substances, which lead to intoxication of the body. As a result, there is a decrease in immunity, and the roundworms that cause coughing freely enter the lungs.

If the infection is not diagnosed in time and treatment is not started, the movement of the larvae leads to injuries of small vessels. And this, in turn, explains that sputum in advanced cases of the disease may contain blood impurities.

Ascaris in children can cause the formation of respiratory failure. Additionally, ascariasis may be accompanied by a change in the color of the skin (they become pale) and the appearance of a bluish tint of the lips.

Impact of pulmonary fluke

If a cough bothers adolescents and adults, then in this case, a disease such as paragonimiasis can be suspected. The cause of its appearance is the pulmonary fluke. These parasites can lead to inflammation and hardening of the lung tissue, which leads to the formation of infiltrates. Over time, this pathological process spreads to the bronchioles, they also get eggs of parasites, purulent exudate and blood. The main clinical manifestation of the disease is cough with sputum production.


The relationship of toxocar and cough

Another reason for the appearance of this pathological symptom may be toxocars, they are also called dog roundworms. The disease that occurs as a result of the penetration of toxocara into the human body is called toxocariasis. The disease can appear in both children and adults, but it is especially dangerous for children.

The size of these parasites can reach eighteen centimeters, the lungs, bronchi and trachea are considered their favorite places of localization. Toxocars can cause severe allergic reactions, the manifestation of which is:

  • cough;
  • high body temperature;
  • blurred vision and wheezing.

Note! A pathological symptom such as a cough may indicate the presence of helminths in the body of an adult or a child

First of all, you need to determine the cause. A cough caused by worms is treated with anthelmintic drugs.
