Not long ago, extremely easy easy deaths of people tick and insect pest and disease prevention has sounded the alarm.
Will people causing health problems common insect far more than a tick and insect, following the introduction of small series to your life in 5 most harmful insects, we must be vigilant against them.1. liver fluke
The "hidden" in the body can be up to 20 to 30 years
Over the years, parasitic disease almost out of the public eye, but with the people on the "special" diet of sought after as well as a family of Metropolitan Yangchong increases, the liver fluke, such as parasites Toxoplasma gondii back to the stage again to grab a central location.
Currently most affected by parasites, when a liver fluke. The 1950s, in the Western Han Mummy has been found in the feces liver fluke eggs, according to this inference in 2100 ago already have this disease.Today, the preference of the freshwater fish health, the Pearl River Delta region in many people unfortunately.
Liver fluke is the main route of transmission in freshwater body liver fluke metacercariae through mouth into the gastrointestinal tract, into the bile duct development for adults. Liver fluke up in humans survive twenty or thirty years, some people ate as a child, metacercariae, wait until the onset of age only.Liver fluke firmly in the liver, not only with human body snatch nutrition, but also to the surrounding tissues cause mechanical damage and metabolites will stimulate the liver tissue changes.
Research has shown that the liver fluke, subject to infection appears abdominal distension, abdominal pain, diarrhea, loss of appetite, indigestion and other symptoms, long-term chronic infection can also cause gallstones, bile duct cancer, cirrhosis and liver cancer and other serious complications.Early in the infection of the liver fluke, apart from a short time a large number of infected metacercariae cases, the lesions are generally not obvious, and individual differences, most people don't feel discomfort or only mild symptoms.
For the control of clonorchiasis, preventing infection is undoubtedly the most important, also, who first discovered early treatment is necessary.Protection point:
Do not eat sashimi, whether there would be no possible infection of the liver fluke? not processed freshwater fish health! chopping boards, if not thorough cleansing is used to cut cooked food, then it may become infected liver fluke of accomplices.
Liver fluke metacercariae is very small, invisible to the naked eye. Therefore, the blooming of the dishes has been the sashimi and chopping boards even after washing cannot guarantee absolute security.Experts emphasize that want to avoid the liver fluke infections, we must consciously change improper cooking, eating habits, cannot guarantee that the fisheries meats no live parasites, the best prevention methods is not fish health, develop good health habits.
In addition, the health food should be strictly separated from equipment handling, blooming, preventing cross-contamination. And liver fluke metacercariae, General temperature reaches 70 ℃ ~ 80 ℃, more than ten seconds to kill. Therefore, the processed freshwater fish health chopping boards available scalded killing the parasites washing.2, Plasmodium
Plasmodium falciparum is a special kind of parasites, can enter the body through the Anopheles, and malaria.
Can the Plasmodium parasite of humanity, that is, there are 4 species of Plasmodium falciparum, Plasmodium vivax, malariae and oval Plasmodium.Malaria-endemic threat to internal and external Exchange frequent, enter in occupies a vast majority of cases.
This year, the Pearl River Delta region, an enterprise of one employee to travel to Africa to do weddings, but soon fell sick and eventually die from malaria. These type of cases of cancer are malignant malaria.In addition, Southeast Asia and mainland areas of Yunnan, Hainan is also the tradition of vivax malaria endemic areas.
Got vivax, usually in one or two weeks of the onset, usually every day of the attack, and very hot.Protection point:
Malaria media is the Anopheles.
Anopheles easy breeding in the mountain. To remove or climbing, the community should do a precautionary measures, mountain wear long-sleeved shirt, long pants, carry water repellent. Return from Southeast Asia, Africa, such as fever, chills occur should consult a doctor has been to these places. Artemisinin malaria drug treatment is the malady.3, Cryptosporidium
After the necessary vigilance against flood
Cryptosporidium is a compact small intestinal parasite eimeria class.
Experts pointed out that the insects in the human body caused by mainly diarrhea, severe or violations to the brain and other organs causing the disease. With the animals, human excrement from the Oocyst, entering the water sources, contaminated food will lead to a new round of infection. Human susceptibility to this worm generally. The worm is AIDS, one of the most common opportunistic pathogens, long-term use of intestinal immunosuppressive agents for cancer patients, organ transplant, hemodialysis patients as well as infants and young children under two years old, easier than other people.Protection point:
Protection against water sources are contaminated with dung patients will, after the flood, the need to guard against the possibility of pandemic occur.
General disinfectant for Cryptosporidia bactericidal effect was limited, but heating to 65 ° c ~ 70 ° c to kill oocysts, feces contaminated clothing can be heated, boiling, sterilization. Immunodepressed subjects usually it is best to drink the boiling water.4, Toxoplasma gondii
You can trigger miscarriage in pregnant women
Toxoplasma gondii parasite belonging to protozoa class, can cause miscarriage in pregnant women.
Shape of intermediate hosts have cats, dogs, people, cattle and other dozens, and finally the host only cats. "Toxoplasma gondii in intermediate host who can only realize the asexual reproduction, dissemination of relatively weak, but in cats, it can be asexual reproduction or sexual reproduction, to the class animal intestinal parasitic well and emit large amounts of infectious oocysts, greatly enhanced dissemination of force, but also enhances the survivability of parasite itself. ”Protection point:
The Toxoplasma infection, prevention first.
Plan made man would not be appropriate for the female cat. Pets in pregnant women before doing the Toxoplasma gondii sieveQuestioning, during pregnancy that reducing exposure to pet and soil, after contact with cats should use SOAP, wash your hands. Cat's family is better to use dry feed, canned food and cooking food feeding.5, mosquito
80 several infectious diseases transmissible
Mosquito belonging to Insecta Diptera: culicidae, approximately 3000 species of the world, is a kind of sucking mouthparts of so small bug.
Female vampire, male smoking plant juice. Female mosquitoes can transmit dengue fever, malaria, yellow fever, filariasis, Japan encephalitis (je je) 80 various diseases, referred to as "the worm" Captain Tegongdui ", is not too much.Specifically, commonly known as the "home" mosquito "," black and of Culex mosquitoes are mainly spread filariasis and je; love day bite of Aedes mosquito is the "flower", the main transmission of dengue fever, Japanese encephalitis and; static attitude different, like "Alice ass" main Anopheles, transmit malaria.
Each year, the month of April to November is the peak of mosquito breeding.
Of these, two breeds of Culex peak in there, in October. From June onwards, Aedes into reproduction. The peak of Anopheles propagation in summer.(Edit: Justin Lin, internships)
