and other content of the video
Play on various web platforms
It has aroused the great concern of many people
Opinions vary online

August 15
Address this issue
Sichuan CDC issued a document to refute the rumors
Sichuan disease control experts said
Guinea worm, also known as Guinea worm
Adults parasitize humans and a variety of mammalian tissues
Causes guinea worm disease
The disease is a zoonotic disease
It was widely popular in
Tropical and subtropical regions such as Africa and India
There were only 14 cases worldwide in 2021
Cases of human infection with Guinea worm Dracaena
Seven of these cases were in Chad, Africa
Only 1 case has been reported so far in the mainland (1995)
There are many nematodes in natural water bodies
Most are not parasitic in humans
A few such as:
Clematis, Guinea worms
It is possible to infect the human body through the mouth
Guinea worms are infected by humans or animals by mistakenly eating sword fleas containing the infected larvae of the worm.
Clematis are infected by drinking water or by devouring hosts containing infectious larvae such as insects, fish, snails, etc.
The worms in the video do not burrow into the human body
Ingestion contains infectious larvae
Sword fleas, insects, fish, snails, etc
That's the key to infection!
Based on videos and photos posted online
Combined with epidemiology and biological morphology
as well as routine monitoring, etc
Neither supports the nematode in the video as a "dragon nematode"
Curator of Chengdu Huaxi Insect Museum
Zhao Li also said
The nematodes in these videos are not "dragon nematodes"
It is a kind of nematode parasitic in the insect
Entered the body of water
There are many insects in nature
There are many that are "harmonious" symbiotic with people and the environment
So you don't have to panic
Prevention of foodborne parasitic diseases
Special attention should be paid to drinking water hygiene
Do not drink raw water from the wild
Avoid raw foods that may infect parasites
Insects, fish, snails, etc
Avoid swimming in unclean water in the wild
