This time of year
Hospitals will admit many cases
Patients with high fever that does not go away
A "black scab" was exposed
The real cause of their fever
recently
Uncle Zheng (pseudonym) of Chun'an
I was hit
"Black scab" on the arm after going up the mountain
Confirmed diagnosis of "scrub typhus"
Uncle Zheng found it after going up the mountain
A "black scab" appeared on the arm
He had a high fever again and again, and his body temperature was as high as 39°C
With generalized rash and malaise
Then he went to the First People's Hospital of Chun'an County
Fever clinic visits
Scrub typhus eschar
After careful examination and physical examination by the doctor
Consider this to be caused by a scrub insect bite
Rickettsial infection (scrub typhus)
After symptomatic medication, the condition improved rapidly
Sudden onset of illness, severe symptoms
Likes to bite the hidden parts of the human body
Scrub typhus has an acute onset and severe symptoms
Some patients will be misdiagnosed
This can lead to severe illness and even death
When chigger mites bite people, they inject an enzyme to cover them. This enzyme makes the person feel paralyzed and does not feel pain during the bite.
Where the bite is bad
I like to bite the hidden parts of the human body
As:
armpit
Under the breast
Perineum
back
So
Keep in mind the three characteristics of scrub typhus
In the early stages of scrub typhus, red papules at the site of the bite are often seen, followed by blisters, and after 98% of cases, black-brown eschar is formed.
Patients have superficial lymph nodes throughout the body will be swollen, dizziness, headache, nausea and vomiting, abdominal pain and bloating, cough and sputum, hepatosplenomegaly, conjunctival hyperemia, etc., which are serious enough to be fatal.
Wet after rain
Scrub bugs are frequent
When entering woodland or meadows
Please be careful!
Take precautions
Avoid sitting and lying on the grass, drying clothes, wear long clothes and pants for outdoor activities, tighten the sleeve collar and trouser cuffs, and apply insect repellent and other insect repellent on the exposed parts of the body.
Eliminate the source of infection
The most fundamental measure to prevent scrub typhus is rodent extermination. Chigger mites are mostly found in the grass of the countryside and in the lawns of the city's parks.
However, scrub typhus is an opportunistic infection, not all grasses have scrub worms, and not all scrub worms carry pathogens.
Early diagnosis and early treatment
If you have an unexplained high fever after activities in the grass or bushes, you should carefully check your body for eschar after insect bites, and seek medical attention as soon as you find it.
