jellyfish are divided into many kinds, but almost every kind has large or small toxicity.
jellyfish’s toxicity comes from their stinging cells. This kind of cell grows at the front end of its tentacle. It is a capsule filled with liquid, with a hollow winding tube inside. There is a small needle called cindocil on the surface of the thorn cell, which is like a switch. When the thorn cell needle is touched, the thorn cell will immediately shoot out of the pipeline. These tubes containing venom will paralyze the stabbed creature.
the most toxic jellyfish known at present is the box jellyfish growing in Australia
:
people will die within 3 minutes if stabbed by their tentacles. Along the coast of Queensland, Australia, about 60 people have been killed by box jellyfish poisoning in the past 25 years, but only 13 people have died in the belly of sharks at the same time. After being stung by jellyfish,
people generally have an electric shock like tingling feeling in a few minutes, and an electric shock like tingling feeling gradually appears in the injured area after a few hours. After a few hours, a linear blood rash with erythema gradually appears in the injured area, itching and burning. The light person can heal himself in about 20 days. More severe cough and asthma attacks, white or pink foam sputum, accompanied by pulse weakness, skin cyanosis and blood pressure decline and other signs of anaphylactic shock. If the rescue is not timely, such stinging patients can die in a short time.
stinging sensation after jellyfish sting
if you are stung by jellyfish, do not wash with fresh water, because fresh water can promote the release of venom from stinging cells, wipe off the tentacles or venom adhered to the skin with towels, clothes and sediment as soon as possible, and clean the injury with sodium bicarbonate (baking soda) or alum. If the injury area is large and the systemic reaction is serious, go to the hospital for treatment in time.
ticks (P í) are also called ticks. Turtles eat
, commonly known as grass steak, dog turtle, grass, cattle louse, Paederus, grass tick, dog bean, cattle turtle, etc. they often lie dormant in grass and plants in shallow mountains and hills, or live in animal fur rooms such as livestock. After ticks bite people, most of them get sick quickly and seriously. The main symptoms are fever, accompanied by general discomfort, headache, fatigue, muscle pain, nausea, vomiting, diarrhea, anorexia, mental depression, etc.
the invisible body disease bitten by ticks is an infectious disease. People are generally susceptible to the disease. Medical personnel or their caregivers who have close contact with critically ill patients and directly contact the patient’s blood and other body fluids may also be infected if they do not pay attention to protection.
tsutsugamushi, also known as Chigger Mites and sand lice, can infect tsutsugamushi disease
tsugamushi disease develops rapidly. If treatment is delayed, fever may occur soon and lead to myocarditis, pleurisy, encephalitis, multiple organ failure, and even death. The occurrence of Chigger Mites in North China, Hong Kong and Macao starts in May every year and reaches its peak from June to September. The weather is warmer and the occurrence period is earlier. Some inexperienced doctors are easy to misdiagnose tsutsugamushi disease as cancer and influenza, and life-threatening events occur from time to time.
when you go out, you can apply some repellents on your clothes, such as potassium sulfide solution, to prevent this parasite from “approaching” you; Once these parasites bite into the skin, they should not be taken out arbitrarily, so as to avoid drilling deeper and deeper due to improper methods. Go to a professional medical institution for professional treatment measures.
the reason why small mosquitoes can have such terrible lethality is mainly because they can infect more than 80 diseases
. Malaria may cause the largest number of casualties: this disease causes about 3 million deaths every year. Malaria mosquitoes that can infect malaria are distributed in central and South America, Africa, Oceania and Central Asia, especially in Africa. In Africa, on average, one child dies of malaria every 30 seconds.
in addition, most mosquitoes can infect filariasis (caused by nematodes). This disease can lead to gumma, abnormal enlargement of the external genitalia and thighs. Worldwide, about 1.2 million people are infected with filariasis. Most species of mosquitoes can transmit viral diseases, including yellow fever, dengue fever, Japanese encephalitis, St. Louis encephalitis, multiple arthritis, Rift Valley fever, chikungan sub fever and West Nile fever. The only thing that can make us feel lucky is that AIDS will not be infected by mosquito bites.
