Parasite in man

Because of the conditions of modern life, parasites to an unprecedented public health problem. As far back as we found in 1976, a random nationwide survey by the Centers for Disease Control (CDC) in Atlanta study, one in six people who carried out that have been examined one or more parasites.

One can carry a few parasites and do not suffer disease symptoms. If her immune system made by another illness or accident in question, however, the parasites canalso lead to problems.

The probability of infection is significant in certain locales or specific population groups. Persons who are traveling abroad, a higher risk than the children in day care and those who care for them.

Parasites are in Webster's New World Dictionary as any plant or animal defined that life on or in an organism of another species and derives nourishment and protection from her, without the benefit - and usually do harm - the host. Parasites that live inhumans range in size from visible worms, such as tapeworms or pinworms, to microscopic organisms, such as Giardia lamblia.

A number of seemingly unrelated factors occurring in the late 20th century appear to have contributed to an increased risk of parasitic infection among North Americans. The major factors are:

1. International travel--Increased travel to parts of Asia, Africa, and Latin America has boosted the risk of acquiring foreign born parasites.

2. Municipal and rural Water supply - Lampeia Giardia, a microscopic organism, the main task assigned to offenders in water disease. Once a threat only to foreign travelers and backpackers, this organism appears now in the U.S. in both rural and urban water systems. It (the water supply of animals is introduced through mountain streams and by human sewage entering public water supplies.)

3. Are used in day care - because they can spread Giardia and other microorganisms by careless winding one day-care centersSource of parasite transmission.

4. Influx of immigrants - many immigrants are asymptomatic carriers of parasites that produce symptoms in North American. Non-English-speaking immigrants often find work in restaurant kitchens, where poor hygiene parasites can be transferred to the food.

5. Return of soldiers from overseas - Over half a million U.S. troops returning from the war in Iraq in 1991, it was said, no blood, because the likelihood of donationthat they are carriers of a parasitic disease called leishmaniasis, which is distributed through the desert sand flies.

6. Household Pets - Pets are hosts for many parasites (in her fur and saliva harbored). Around 240 different infectious diseases can be transmitted from animals to humans.

7. Regional Exotic Food - Raw, rare, or undercooked meat and fish dishes, and vegetables such as water, watercress and lotus root can harbor parasites.

8. Antibiotics and immune-suppressingDrugs - The reduction of positive intestinal flora after the use of these drugs weaken the body's defenses against hidden intruders.

9. The sexual revolution - parasites to a different kind of sexually transmitted diseases.
