Strongyloidiasis And What You Need To Know
Strongyloidiasis is a dangerous parasite among the gastrointestinal parasites. It can exist for a long time in the human body and can cause many very dangerous, even life-threatening complications. Understanding disease is the best way to effectively identify and prevent Strongyloidiasis.
1. What is Strongyloidiasis?
Strongyloidiasis is caused by the appearance of strongyloidiasis larvae that enter the human body by means of the skin, enter the vein and go to the heart, the lungs, then the windpipe, almost, then they move down the food. and enter the intestine to develop into adult worms. Strongyloides live a long time in the human body and cause many dangerous complications, and can be fatal. The number of people infected with strongyloidiasis is quite high in our country, accounting for 1-2% of the total population

2. Causes of strongyloidiasis
Adult strongyloid parasites usually live in the lining of the small intestine and they lay eggs here, they can live in an external environment.
. Strongyloid eggs will develop into free-form larvae and they are excreted in the stool. When eel worm eggs are excreted into the environment, the larvae continue to develop into adult worms and lay eggs in the soil. In our habitat, this larva can continue to invade the human body and parasitize the sick.
Eel worms have a shallow, horizontal shell, and the mouth of the worms has two lips. The head of an adult eel is elongated in shape and its tail is pointed, the size of an adult eel worm is about 2 x 34 mm
For eel eggs with an oval shape, the inner size of the egg is from 50 - 58mm x 30 -34mm. Strongyloid larvae grow very quickly to become larval esophagus-shaped larvae in the eggs, and they escape on their own in the small intestine, go out through the digestive tract, so when testing or stooling very rarely see eel worm eggs in the stool. In the case of patients with severe diarrhea, eelworm eggs can be seen.
When the larvae escape outside the environment, the larvae continue to develop into cylindrical larvae, able to penetrate through the skin to enter the human body or they live freely outside the environment. The humid outside environment is a suitable factor for developing strongyloid larvae, but in temperate regions or cold climates they help develop.
3. Symptoms of strongyloidiasis
People with Strongyloidiasis do not have clinical manifestations, however, some of the following may be indicative of strongyloidiasis
Eel worms in human intestines
Shabby abdominal pain, transient or intermittent.
Local itching occurs when larvae enter the body
Asthma for allergy sufferers
Ectopic strongyloidiasis can be found in the esophagus, lungs, and lymph nodes
Feces smell like foul, fishy.
In addition to the above signs, when testing feces, results in feces containing strongyloid larvae will be available immediately after taking stool for testing.
Examining the blood test shows mild anemia
Assay: positive for Strongyloides antibody (ELISA Strongyloides IgG positive)
4. Incubation period
Reservoir: The human body is a reservoir for the development of Strongyloides stercoralis strongyloidiasis. Strongyloides can also survive and persist in some animals such as dogs, monkeys and apes.
Incubation period: Within 2-4 weeks is the time for larvae to penetrate through the skin and develop into strongyloidiasis and lay eggs. When the worm eggs go out into the environment, the eggs develop into larvae
Transmission period: The life time of an adult female worm parasite from the time they are fertilized and the egg is formed to lay. The duration of transmission of strongyloidiasis can be up to about 35 years, in case of an infected person.
5. How to prevent strongyloidiasis
Treating strongyloidiasis parasites takes time and costs to treat, so prevention is better than cure. Each of us needs to be aware of some of the following issues to limit infection, reinfection and disease transmission in the community.
Sanitation in daily life: Ensuring safe manure, sewage and waste disposal in the living environment. Good hygiene for the area near the home, indoor and play areas of young children
Personal hygiene: Establish a civilized lifestyle, always wash your hands before eating, when preparing food or every time you go to the toilet, eat raw vegetables to wash thoroughly.
Check parasites periodically every year, deworming 2 times a year, 3-6 months apart.
Protective use is required during work such as contact with soil, especially in areas contaminated with manure.
Strengthening the body's resistance by many additional ways such as fresh, clean vegetables, exercise, sports daily and helps to fight off immune decline, avoid causing disease outbreaks.
Raising people's awareness in community sanitation is a top issue to fight back the infection.
