10 human parasites
Human Parasite Infestation
In modern times the average person does not hear much about human
parasite infection. In fact, thousands go through their entire lifetime
without ever having the thought cross their minds. But have you ever
given some thought as to the specifics of human parasites?
Human Parasites an Age Old Issue
The truth is that as long as there has been human existence, there have
been parasites. Scientists discovered the reality of human parasite
as an age old issue, dating back to the year 1200 A.D. with evidence
of parasitic eggs of schistosomes in Egyptian mummies. Most human parasites
belong to one of four groups - flukes, tapeworms, roundworms or protozoa.
With improved sanitation utilities, and focus on healthful surroundings
and human lifestyles, Human parasites are not so much a threat in
the United States. However, in underdeveloped countries where primary
healthcare and inadequate access to bountiful running water are a
challenge, human parasite epidemic is very real.
10 Human Parasites
Here is list of ten human parasites.
1. A common human parasite that is contagious through soil and
unsanitary condition is the ascaris lumbricoides, also referred to as
the giant intestinal roundworm. The Global Network for Neglecged Tropical
Diseases estimated that this parasite will affect close to one billion
persons at any point in time, causing 60,000 deaths per year.
2. Billions of people regardless of global location are affected
by the hookworm, of which there are two species known to man. These
penetrate the skin and can cause adverse anemia and blood loss.
3. It is relatively to know whether you have pinworms, as most
sufferers experience and itchy bottom. The female pinworm deposits her
eggs in the anus at night, causing irritation to the tissues of the
4. There are two types of tapeworm (taenia) as well - the beef
tapeworm and the pork tapeworm. Clearly these are contracted though
eating poorly cooked beef and pork, and can be lethal as they negatively
affect the nervous system.
5. The oriental liver fluke is flat and sped like a leaf. It
is known widely in Far East territories and is transmitted though eating
undercooked or raw seafood. It is posited that bile duct cancer is as
a result of the oriental liver fluke.
6. Schistosomes mentioned earlier are mostly found in Eastern,
South American and African regions. This parasite penetrates the skin
while the host is immersed in contaminated water. Infection results
in inflated abdomens caused by inflammation of the spleen and liver.
7. The parasite plasmodium causes malaria and is transmitted
through the bite of the Anopheles mosquito. Signs of malaria include
ague, fever and urine in the blood.
8. Chaga's disease is as a result of the trypansoma cruzi. The
triatomine bug bites the host while asleep and defecates in the bite
site, causing the host to itch. When the person scratches, the parasite
is introduces into the blood, and cause cardiac issues.
9. The giardia intestinalis, found in most of the world, is normally
contracted from drinking contaminated water, and causes diarrhea.
10. Hundreds get entamoeba histolica from consuming contaminated
food and drink. Most infected are not affected; however, about 10% of
infected persons experience bloody stools and internal organ abcesses.
