What are helminths?

This refers to parasitic worms that can live in the human or animal body and use it as a source of nutrients. They are commonly known as worms. Diseases caused by parasitic worms are called helminthiases.

Helminths differ in their structure, life cycle, route of infection, and the parts of the body they can inhabit. Some parasites primarily affect the intestines, while others can spread to tissues or internal organs.

What types of helminths are there?

There are many types of parasitic worms, but based on their structure, they are conventionally divided into three main groups:

Therefore, different types of helminths can vary significantly from one another. This is important because symptoms and diagnostic methods depend on the specific parasite.

What is helminthiasis?

Helminthiasis is a disease or group of parasitic infections caused by helminths.

The course of the disease depends on the type of parasite, the number of parasites, and their location in the body. In some cases, the infection may remain unnoticed for a long time. In others, a person may experience digestive symptoms or changes in their general well-being.

How does helminth infection occur?

Helminth infections can occur through different routes. The mode of transmission depends on the specific parasite and its life cycle.

The most common routes include:

• eating unwashed vegetables, fruits, and herbs;

• drinking contaminated water;

• consuming meat or fish that has not been properly cooked;

• ingesting parasite eggs through unwashed hands;

• contact with contaminated soil;

• contact with infected animals or household objects in the case of certain parasite species.

   

How are helminths transmitted?

The answer to the question of how helminths are transmitted depends on their species. Some parasites enter the body through food or water, while others can spread through direct or indirect contact or penetrate the skin.

Particular attention should be paid to hand hygiene, safe drinking water, and proper food preparation. Simply coming into contact with another person or an animal does not automatically mean infection will occur. The risk depends on the specific parasite and its mode of transmission.

What are the possible symptoms of helminth infection?

Symptoms of helminth infection can vary considerably. Some people have no noticeable symptoms at all, so it is impossible to reliably determine whether parasites are present based on how a person feels alone.

Possible symptoms include:

• abdominal pain or discomfort;

• bloating;

• nausea;

• changes in bowel movements;

• itching around the anus;

• fatigue and weakness;

• changes in appetite;

• unexplained weight loss;

• certain skin manifestations.

It is important to understand that these symptoms are not specific to helminthiasis. They can occur with many other diseases and conditions.

How can the presence of helminths be confirmed?

Symptoms alone are not sufficient to establish a diagnosis. The doctor considers the patient’s complaints, possible route of infection, age, dietary habits, travel history, and other factors before prescribing laboratory tests if necessary.

Different diagnostic methods may be used depending on the suspected parasite. In some cases, a stool sample is examined; in others, blood tests or additional examinations may be required.

There is no need to look for a single universal test for helminths that can detect all types of parasites equally well. The doctor determines which test is most appropriate.

You can undergo the necessary laboratory tests at the ZDRAVO medical center.

Do helminth infections need treatment?

Treatment for helminth infections depends on the specific parasite and the confirmed diagnosis. Anthelmintic medications differ in how they work, so there is no universal remedy that is effective against all parasites.

Taking these medications on your own “for prevention” is not recommended, especially for children, pregnant women, and people with underlying health conditions. It is best to consult a doctor first and determine whether treatment is necessary.

If you have digestive symptoms, you can consult a family doctor or a gastroenterologist for an initial assessment. Children can be examined by a pediatrician.

How can you reduce the risk of infection?

Although it is impossible to eliminate the risk completely, following simple hygiene rules can help reduce it:

• wash your hands after using the toilet, going outdoors, and coming into contact with soil;

• wash vegetables, fruits, and herbs before eating them;

• use safe drinking water;

• cook meat and fish thoroughly;

• follow hygiene rules when caring for pets;

• avoid consuming food from questionable sources.

Prevention should take into account the specific route of transmission, as different helminths have different life cycles.

Conclusion

Helminths are parasitic worms that can infect humans and cause helminthiasis. There are several groups of parasites, and infection can occur through food, water, hands, soil, and other sources, depending on the specific species.

Abdominal pain, weakness, or other nonspecific symptoms alone do not confirm helminthiasis. If a parasitic infection is suspected, it is advisable to consult a doctor and undergo the recommended diagnostic tests rather than taking medication without medical advice.
