What are the different types of parasitic diseases?
parasites are organisms that live on the host or host and get food from the host. Although there are thousands of well -known parasites, only about 100 people affect people. Problems caused by parasitic infections range from minor discomfort to serious diseases. Three types of parasites that affect humans are protozoa, helminths and ectoparasites. Some parasitic diseases eventually disappear in itself, while others may cause disability or death if they are not treated. Insects that bears the disease through its bite is called a vector. The most common vector is a mosquito that can transmit yellow fever, philarosis, ivory, heart worms and malaria. Malaria is the most devastating parasitic diseases that kill more than a million people every year, especially small children in Sub -Saharan Africa. Flies can also be vectors and various types of parasitic diseases such as sleeping disease and river blindness.
Helmints, the second category responsible for causing parasitic diseases, are large, multi-cell organisms that can be seen with the naked eye in their adult form. This group consists of flat worm, suck like flukes and tapeworms, thorny worms and round worms. Worms generally do not feed the host, but take nutrients from the host. The signs of worms infection include itching, vomiting, weight loss, increased appetite, abdominal pain, intestinal obstacles and joint and muscle pain. While parasitic worms can be found around the world, they are most common in China, the Middle East, South American, Africa and the Caribbean.
ectoparasites are organisms that connect or put in the skin for a long time and include ticks, mites and fleas. Tick -borne burrows under the skin and releases toxins that cause brilliant diseases, including fever with rocky mountain, fever, Colorado tick fever and Lymes disease. Mites such as chiggers and scabies are common in warm or crowded oblastech and cause skin irritation. Fleas can carry Typehus and bubonic plague, also known as black death.
contaminated water and food are frequent sources of parasitic infections. Giardia infection occurs around the world and comes from untreated water. This is more common in people who went to hiking and drinking a stream or river water, or who live in areas with insufficient water hygiene. Treatment of water or the use of bottled water when traveling in such areas can prevent many parasitic diseases. Proper hand washing before preparing or handling food is another significant preventive measure.
parasitic diseases are growing in tropical and subtropical climate. The use of pesticides has removed insects born in many parts of the world, such as malaria. Some regions, unfortunately, the net has resources to take preventive measures or to treat those who get infected. In addition to those who die of malaria, tropical parasitic diseases such as lymphatiFlyariosis, onchocerciasis and the Guinea worm, demand another half a million victims a year.
For preventive measures such as drinking only treated water, hand washing and using insect sprays, it can be very successful in avoiding parasitic disease. If a person has symptoms of parasitic infection, he should seek quick medical attention. Most of these infections can be successfully treated with antibiotics and other drugs.
