10 dangerous small animals in Vietnam

Being bitten by insects is not a rare thing in everyday life. However, subjective, non-performing first aid measures and treatment may lead to very serious consequences for health and life.

Doctor Phan Xuan Trung, Medic Center (HCMC) said, insects have many types, with different properties and levels of toxicity. Depending on the bite of any insect, appropriate treatment is required.

'If burned by dangerous species such as bumblebees, scorpions, etc., you should take the victim to a medical facility so that the doctors will have an appropriate anti-toxic solution and prevent anaphylaxis. For less dangerous species such as fire ants, honey bees, it is only necessary to take simple first aid measures, to take more anti-allergy and anti-inflammatory drugs, ' Trung said.

The following are some dangerous small animals in Vietnam, the injuries and first aid measures should be taken immediately when they are burned, as recommended by medical experts:

Bees

Most bees have venom, depending on the species that will be poisonous or more or less. There are lethal types with just over 10 stings like bees, earthen bees, but there are also types that are not as dangerous to health as honey bees.

Bee venom has a main component of protein with invasive enzymes, blood enzymes, cells, allergens and acetylcholine . In case of being burnt by bees, the victim will be cyanotic, shocked, cardiovascular collapse ., can be fatal if not cured.

When being stung by a bee, the first thing to do is to prick the needle from the burned area with a sharp object such as a knife tip, a needle tip . Do not use a hand to take needles, as it will facilitate the venom to penetrate deeper body.

Then, wash the stain with soap or antiseptic solution, then apply a cold washcloth or ice pack to the swollen area for about 15-20 minutes to relieve pain (do not apply directly to the sting site).

Fire ants

The fire ants are not life-threatening, but the persistent sting is really a terrible thing. The venom of some fire ants can cause symptoms such as dizziness, dizziness, shortness of breath or shock ., depending on the immune system of the burned person.

When burned by fire ants, soothe the bite with soap and water, then use an ice cubes for about 10 minutes. If the blister is bitten, then it should not be broken, but a light swab should be taken because if the blister breaks, it can lead to an infection.

Caterpillars

The caterpillars are the larvae of butterflies. They do not burn people, but the hairs of most caterpillars secrete an itchy substance that irritates the skin when people touch it.

The hairs of some species may cause severe pain in the exposed skin, accompanied by an allergic rash. Haemorrhage can occur within 2–3 hours and for several days. Other symptoms include lymphadenopathy, headache, fever, hypotension and severe seizures, which can be fatal.

When pinching on the skin, be careful to use a stick to take it deep, brushing off the visible hair. Then wash your skin with soapy water and cold compresses to reduce swelling and relieve pain.

Avoid scratching much on the itch as this can cause hair and spikes to penetrate deeply into the skin causing prolonged symptoms.

Fleas, lice and dog ticks

Very small in size, these insects can live in bushes or on many pets like dogs and cats. Their burns not only cause throbbing, swollen or allergic reactions, but they can also cause redness. The rat flea is also the medium that transmits lymphadenopathy, which once caused epidemics that killed tens of millions of people in Europe.

When bitten by these insects, they should be pulled slowly, or use fire, rub alcohol, oil to let them fall off themselves, to prevent their teeth from sticking to the skin, which can cause infection. Then wash the bite site with soap, then apply alcohol or antiseptic oil to the bite site.

Spider

The spiders in Vietnam are not as toxic as many of their species in Africa or South America. Spider stings often cause the skin to swell, red, and ache. Sometimes causing dizziness, fever but not too dangerous.

When the spider is burned, clean the burned area with soap and ice. If necessary, aspirin can be taken as directed by your doctor.

Scorpion

The scorpion is not an insect but a spider-shaped animal. In Vietnam, there are two common beetle species: black scorpion and brown scorpion.

Sting stings in the tail of these scorpions are like bee stings, causing swelling, redness and aches, sometimes bruising. Sometimes the victim just feels a little itchy at the site of the injection, but then he gets dizzy, sweating, watery nose, nausea, and stiff limbs. In limited cases, scorpion venom can cause anaphylaxis, life-threatening.

In the case of a scorpion burn, the burned person needs to apply ice and spray anti-pain medication on the sting or take an analgesic type of ingredient with paracetamol. For children and people who are more prone to reactions to stings, especially those burned on the face, it is necessary to seek emergency treatment immediately.

Centipede

Centipede is a multi-legged animal, often living in dark, humid places such as under beds, under cabinets, dry leaves items . even in clothing. They can secrete toxins by biting with the front teeth, causing the object to swell. The venom of the centipede is not fatal, but makes the person bitten extremely painful. The accompanying symptoms are vomiting and fever.

When you have a bite, it is necessary to squeeze the venom out of the blood. Then wash the bite with cold soaps and soap to help reduce pain and reduce swelling. Should use more analgesics and anti-inflammatory.

Mosquito

Perhaps, no one in this world has ever been bitten by mosquitoes. It seems harmless, but mosquito bites also cause skin infections, causing fever.

Among mosquitoes, anophen mosquitoes can transmit malaria. These parasites live and multiply in human blood cells and cause symptoms such as nausea, flu, fever and cold bouts. In the case of danger, the disease causes a coma to die and die.

Wash mosquito bites with acidic soap or diluted vinegar.

Horsefly

Buffalo flies are a large fly that often burns and absorbs blood from cattle. They don't forgive people either. Buffalo fly stings cause persistent aches, which can last for days and produce other complications such as high fever, seizures, and coma.

When being hit by a firefly, the way of handling and sting of other species is to wash with soap and ice.

Stink bugs suck blood

In Vietnam, the discovery of blood-sucking bugs is particularly interested in public opinion.

According to studies done around the world, blood-sucking bugs can pass Trypanosoma cruzi intracellular parasites into human bodies through stings, causing chaga sleeping sickness.

Using this dangerous disease, the victim will fall into a state of fatigue, sleepiness and immunity. When it becomes chronic, it can cause blood clots leading to death.

According to records in Vietnam, after being stung by stinking bugs, on the skin of patients, only a small red nodule, about 1-2 mm, is not swollen.

Currently, the research on this insect in Vietnam is incomplete.
