It's a holiday season
Whether it's a tomb sweep or a trip
Quite a few people have outing plans
But as the weather gets hotter
It's also the season for all kinds of insects
It is especially active in meadows and fields
Recently, someone has been recruited
I almost lost my life due to an insect bite
After a woman in Foshan "cleared".
High fever does not go away, respiratory failure
Recently, Ms. Huang
A week after the mountain festival came back
Recurrent fever is present
The body temperature can reach up to 39.5°C
It is also accompanied by headache, chills, and fatigue
A red rash appears all over the body
After hospitalization
Ms. Huang gradually appeared
Acute renal failure, respiratory failure
Multi-organ damage such as liver injury
He was eventually diagnosed with severe scrub typhus
Fortunately, it was handled in a timely manner
Ms. Huang escaped
The weather is getting hotter
Scrub typhus will enter the peak season
Scrub typhus is an acute natural infectious disease caused by the infection of the human body by Rickettsia orientalisa carried by scrub worms.
In Guangdong, in fact, there are scrub insects all year round, but the temperature is high and humid in summer, and the scrub insects are more frequent. As a result, the number of scrub typhus patients increases significantly every year at this time.
Doctor's introduction
Scrub bugs are small and easy to be overlooked, and after being bitten by them, they often do not hurt or itch, so many people are unknowingly tricked.
At the site of the scrub insect bite, a painless red papule of about 0.3-1.0 cm in size may appear, followed by the formation of blisters, necrosis and bleeding in the central part, and the formation of a round or oval black crust, which is called eschar.
Eschar that forms after being bitten by a scrub bug
The onset of the disease is acute, and the clinical manifestations are diverse and complex, with symptoms such as high fever, toxemia, rash, eschar and lymphadenopathy, and hepatosplenomegaly.
In addition, there are many complications, which can lead to multi-organ damage, such as toxic hepatitis, bronchopneumonia, myocarditis, meningoencephalitis, gastrointestinal bleeding, acute renal failure, etc., and in severe cases, it can be life-threatening due to organ failure.
However, the prognosis is generally good with timely diagnosis and symptomatic treatment.
Except for scrub bugs
There is also a bug recently
It is also in the period of high incidence of "causing trouble".
The man went to the mountains
Being bitten by a tick
recently
Tongji Medical College, Huazhong University of Science and Technology
Wang Jian, director of the Department of Dermatology of the affiliated Liyuan Hospital
A case of tick bite was admitted to an outpatient clinic
Patient Mr. Zhou
Go out into the mountains
When I got home, I felt itchy on the outside of my right leg and stomach
Take a closer look
There is a small black dot on the skin
There is a head and claws
Still moving slightly
He tried to pull it with tweezers
But he couldn't pull it out
Only then did I rush to the hospital to deal with it
Doctor's introduction
"Fortunately, the patient did not pull out the worm directly!" Wang Jian said that it was a tick that bit Mr. Zhou, and after biting the human body, it will deeply root the mouthparts into the skin to suck blood, and at the same time spread pathogens, which may cause hemorrhagic fever, forest encephalitis, Lyme disease and other diseases.
If bitten by a tick carrying the new bunyavirus, it may also cause "fever with thrombocytopenia syndrome", or "fever with syndrome" for short. The main clinical manifestations of this disease are fever, thrombocytopenia, and leukopenia, and some patients may die due to multi-organ failure.
If you "pull out" after being bitten by a tick, it is easy for the mouthparts and head of the tick to remain in the body, resulting in pathogen infection. If you accidentally pinch the tick during the "hard pulling" and come into contact with the tick's body fluids, you may also be infected with the virus.
Wang Jian suggested that you can use a cotton ball dipped in liquor or 75% alcohol, put it on the insect body for anesthesia, and wait for the tick to "get drunk" before gently taking it off.
Recently, there have been frequent activities of sacrificial sweeping and outing
It's important to learn a little bit about insect control
I don't want to be tricked
Keep in mind the key points of insect control
Wear long-sleeved clothing when entering the woods and grass, and tie your trouser legs tightly or tuck them into your socks or shoes. Apply a repellent, such as a commercially available repellent containing DEET or toilet water, to bare skin.
Do not sit on the grass for long periods of time.
After the field activity, double-check yourself or each other for bugs or crawling on your body and clothing. For example, after taking your pet to a place such as grass, you also need to check whether there are insects attached to your pet in time.
If you have fever, rash, especially eschar (a characteristic of scrub worm bite) and other suspected symptoms after going to the field, you must seek medical attention in time, and inform your doctor of your history of field activities.
Outdoor activities
We must do a good job of prevention
Hurry up and forward to remind the people around you
What other insect prevention tips do you have?
