After a picnic in the park, a woman's calves were covered with "big red spots" and were extremely itchy after being bitten...

Summer leisure time

Go take a walk in the park and enjoy the breeze

It's very pleasant

However, in Guangdong outdoor

There is a kind of ferocious little insect that is particularly active

This insect is smaller than a sesame seed.

The bite bag is bigger than a goose egg

Also caused a lot of redness and swelling

Not long ago

A woman in Shenzhen went to the park for a picnic

After a while, I felt my calves getting more and more itchy.

Take a closer look

Shocked! Stunned!

A good pair of legs

At one time, it was filled with multiple "big red envelopes"

It's even more poisonous than a mosquito!

This small black insect is commonly known as "small bite"

Scientific name: midge

After being bitten by a midge

Initially, the symptoms are similar to those of a mosquito bite.

This also makes many people mistakenly think that they are bitten by mosquitoes.

But in fact

Symptoms of midge bites are more serious!

Edema, inflammation, and extreme itching may occur

Some are difficult to heal

Main symptoms:

❏ The spots after the midge bite are large and appear in large numbers;

❏ The edema is very obvious and may be accompanied by inflammation and blisters;

❏ It is more itchy than mosquito bites. In severe cases, papular urticaria may occur. Floral water and wind oil are basically ineffective.

❏ The redness and swelling will basically last for several days and will be more difficult to heal;

❏ After symptoms subside, dark spots may appear and it may take a while for them to return to normal.

Midges are relatives of mosquitoes but are smaller than mosquitoes. They are only 2 mm long and are mostly brown or black. Their wings are almost invisible. Midges fly fast and irregularly, making them very difficult to catch.

The most common midges that feed on human blood are Culicoides, Miè, and Leptocephalus. They can be divided into aquatic, terrestrial, and semi-aquatic types according to the different reproductive habits of the larvae.

The regions in my country most affected by it are Guangdong and Fujian.

Midges generally do not act alone.

Usually flying in a flock in the air

In summer, there are many

When you meet someone, you are covered in

Midges can carry some pathogens

Like Japanese encephalitis virus, dengue virus

But don't panic!

At present, there are few diseases transmitted by midges to humans in my country.

Mostly spread among animals

Filariasis, protozoan diseases, parasitic diseases, animal blue tongue disease and other diseases

Not a big threat to humans

How to prevent it? Do these things

▼

1. Wear long sleeves and long pants when going on an outing, not shorts or short skirts.

2. Try to stay away from areas with lush greenery near the lake. If it is unavoidable, carry some mosquito repellent with you, such as mosquito repellent bracelets, mosquito repellent tissues, mosquito repellent liquid, cooling oil, etc.

3. Midges like moisture and rotten smells. The smell of sweat can also attract them. Pay attention to personal hygiene. Women should use less perfume.

4. The screens at home must be "tight and leak-proof". Ordinary mosquito screens cannot prevent the invasion of midges at all. They must be tight and fine!

5. Clean out the "nests" of midges, fill in potholes, remove stagnant water, block tree holes, and remove moss.

6. Seek help from a professional disinfection company when necessary.

If you are bitten, try not to scratch it.

May cause secondary infection

You can do this

▼

1. Apply soapy water to keep the bitten area clean. If the blister is accidentally broken, disinfect it with iodine for about 0.5 hours each time.

2. Take appropriate medications. Those with obvious skin symptoms should take anti-allergic drugs, and those with secondary infections should use antibiotics.

3. If you experience severe symptoms such as high fever, headache, nausea, vomiting, or impaired consciousness, you should seek medical attention promptly and inform the doctor of any history of midge bites.
