Parasitic Diseases in Humans – Types of Parasite

parasitic diseases in humansINTRODUCTION

Plants or animals that stay in or on a host and feed or get nutrients from the same host are defined as parasites. Poor hosts do support parasites regardless of whether the relationship is neutral or harmful. Hosts seldom achieve from this arrangement. Almost every time hosts are  killed by the parasite frequently in scenarios whereby the parasite has a negative impact on the host. Parasites do vary in two types that is to say; following are some parasites and parasitic diseases in humans:


These stay in the body. They hide in major areas such as the bloodstream, brain, liver, muscles or digestive systems of animals.


These stay on the body surface. They do not enter the body but cause severe damages such as rashes and itching that one cannot avoid and as a consequence cause body irritation. Parasites in general body discomfort be it in or outside the body.


There are several categories of parasitic infections which do affect animals and plants although the most taught are those that affect humans and are mostly caused by Protozoa, arthropods and helminths.
Protozoa parasites are organisms which are single-celled or contain one cell as will be illustrated below. This is normally in the food and water we consume since they are contaminated by the animal waste. The protozoa infections that affect our digestive system are mainly giardia and amoebic dysentery.

All the signs and symptoms such as diarrhea, weight loss, dehydration and stomach cramps are clear once one is infected by giardia. In addition, other protozoa are spread by vectors such as the mosquito that infects the tissue or the blood and Toxoplasma gondii that infects rodents, cats and people. Based on estimations by the scientists, 1/3 to 1/2 of the population live with the parasite especially in the African continent and this is because of the vast exposure to foods like mutton and beef that causes schizophrenia, reduced reaction time and suicides. Whereas humans are affected in this way, these parasites affect the animal’s behavior.

The Helminth contain many cells and are passed on through polluted food and water. These stay either inside or outside the body. Many know them as worms which include tapeworms, flatworms, thorny-headed worms and tapeworms.
Ectoparasites are also known as Arthropods which are usually temporary animal parasites and plant parasites. These multi-celled parasites do feed or stay on the skin. Examples include insects and arachnids such as ticks, mites, fleas and mosquitoes. Parasites are spread in many different ways such as food, contaminated water, sexual contact, blood and just to mention but a few.


Doctors have come up with several ways of diagnosing parasites such as performing x-rays, magnetic resonance imaging (MRI), a faecal exam whereby a sample of stool is collected and checked for eggs and parasites themselves, an endoscopy or colonoscopy if the stool exam results are inconclusive and a blood test. Additional tests in case of other infections may be ordered for by the doctor to look for bacteria and other things.


Parasitic infection can be got by anyone though some are at a greater risk of getting it than others.


Treatment plans are due to the specific diagnosis and it’s only the doctor to prescribe the medications such as treatment of trichomonas or cryptosporidiosis. And for pregnant women, prescriptions for toxoplasmosis is given unless otherwise. Other treatments such as taking plenty of water or fluids could be recommended so as to relieve the hidden symptoms such as those that cause diarrhea and often lead to dehydration.


Many procedures can be followed to narrow the risk of attaining a parasitic infection. These include; cooking food to the recommended temperature, limit consuming water from lakes, ponds and other water bodies and regular washing of hands.

In conclusion, in case of any signs and symptoms, always seek medical advice as soon as possible so the medical personnel can assist. Early treatments can help reduce the spread of infection to other people.
