Why can a small flying insect that is common in the home cause such terrible consequences?
01.
The small flying insect that caused the accident: a moth gnat
The small flying insect that caused the accident in the news is called a moth [ruì].
Moths, midges, commonly known as mothflies. In urban areas, gnats larvae mainly inhabit places such as stagnant water in sinks, U-shaped drains, toilets, bathroom washbasins, and damp rags. After emergence, adults often move near toilets, kitchen drains, and sinks.
Although, this little flying insect is quiet most of the time, it can carry a variety of disease-causing microorganisms!

The doctor said that when we beat the gnats, our hands come into contact with small flying insects, contaminate bacteria, and then rub our eyes with our hands, and the bacteria are brought into the eyes, and the eyes are the natural "culture medium" of bacteria (so not washing hands and rubbing eyes is a direct fuse)......
Not only the bacteria carried by gnats, but also the bacteria that can be easily transmitted to humans through contact, causing infections of the eyes, nose and other parts. The larvae of gnats can even parasitize the human body and cause infections (eggs are laid in open wounds in homeothermic animals, including humans, and the larvae hatch a few hours later, enter the wound and feed on living tissue, causing disease).

What should I do if a gnat accidentally flies into my eyes?
First of all, don't rub it.
In general, a strong foreign body sensation stimulates the secretion of tears, which helps to flush the worms out. Rubbing may damage the surface of the eye and even leave the remains of gnats in the eye.
Secondly, if the flying insects cannot be discharged on their own, you can ask others to blow the insects out. Or use normal saline, purified water to rinse and drain a large amount, and use levofloxacin eye drops, or tobramycin eye drops to prevent infection.
Third, when the gnats go deep into the eyelids and cannot save themselves, they need to go to the hospital immediately.
Fourth, if the eye irritation symptoms are still not relieved after the flying insects are discharged, or if there are symptoms such as eye redness, eye pain, and vision loss, you should go to the hospital immediately.

How to avoid the "attack" of gnats?
It is important to do a good job of environmental remediation! Specifically:
(1) Clean kitchen sinks, washbasins, bathrooms and other areas regularly to avoid garbage and organic dirt remaining in the sewer and reduce the generation of stagnant water. It is recommended to brush and disinfect the drain and floor drain cover every month.
(2) If conditions permit, install anti-reverse, anti-backflow devices or insect-proof floor drains.
(3) Put special insecticides when necessary, and wear goggles to protect your eyes when killing insects. By the way, it is also important to wash your hands in time after pest control!
