High fever 40 ° C, multi-organ failure, platelets plummeting to less than half of the normal value ...
Ninghai Zhou's old uncle was usually in a tough body, but a sudden high fever put his life in danger. He was diagnosed with a new Bunia virus infection, most likely from a bite from a tiny tick.
Doctors remind that ticks are active in summer,
Citizens should take precautions to avoid being bitten.
High fever 40 ° C, platelets plummeted
Zhou Laobo, who lives in Ninghai, is more than 70 years old this year and is usually tough. In early July, he began to have a fever without warning, and he had little strength in his hands and feet. The family sent the old man to the local hospital, the cause of the disease has not been found, and the old man's physical condition is not as good as a day.
A week later, the family transferred Zhou Laobo to the emergency department of Ningbo Huamei Hospital (Ningbo Second Hospital) at the University of Chinese Academy of Sciences. When he was sent to the emergency department, he was unconscious, his hands and feet were basically unable to move, his speech function and swallowing function were impaired, and he had multiple organ failures, and his life was in danger.
After examination, the unit value of Zhou Laobo's platelets also dropped to 40, and the unit value of healthy people was above 100.
Liu Peng, director of the emergency department of the hospital, realized that Zhou Laobo was most likely infected with the virus.
What kind of virus is it? He inquired in detail about the living environment and labor of the family members and the elderly. The family told that the old man was in the countryside of Ninghai, and there were rats in the residence, and there were often grasses and bushes in the places where they usually worked.
"It is likely to be a new bunia virus, and summer is the high season. High fever and platelet drops are also typical symptoms of the new Bunia virus. Liu Peng decided to test the old man for antibodies to the new Bunia virus, and the diagnosis was positive, and the old man was indeed infected with the new Bunia virus.
It is highly likely to be caused by a tick bite
Doctors speculate that combined with multi-faceted factors, Zhou Laobo's infection is most likely related to tick bites. That is to say, ticks carry a new bunia virus on their bodies, and after Zhou Laobo was bitten, it led to infection.
The new Bunia virus is mainly transmitted by ticks, which are generally active from April to October, tending to occur in hilly areas, mostly in forests, bushes, open pastures, grasslands, mountains and other environments.
Tick bites generally cause inflammatory allergic reactions to the skin, which can be cured with correct treatment and symptomatic treatment. If there is a pathogen in the tick, it may cause other diseases.
Liu Peng introduced: "Cases of infection with the new Bunia virus are rare among residents in Ningbo City. The emergency department encounters patients referred from the surrounding areas of the city, which is related to the living and working environment, and the other is the citizens who have returned from travel and have clearly been bitten by ticks. ”

Hot summer days,
Tick bites are frequent
Don't look at it as unremarkable,
"Tick",
In severe cases, it may be a danger to life!
Ticks, also known as cattle lice, dog beans, and grass crawlers, are close relatives of spiders and belong to the family Arachnids. Adult ticks have a strongly shellized shield plate on the back of the body, commonly known as a hard tick; if there is no shield, it is commonly called a soft tick. The body is oval, the abdomen is flattened when not sucking blood, the back is slightly raised, and the adult body is 2 to 10 mm long; after full of blood, it is swollen like red beans or castor seeds, and the large one can be up to 30 mm long.
Ticks can transmit a variety of diseases, such as the well-known fever with thrombocytopenia syndrome, Lyme disease, forest encephalitis, Babesiosis disease, tick-borne typhus and so on.
Comparison of ticks before and after blood sucking
Ticks are generally active from April to October and do not fly and jump, which limits its range of activities, and mostly lives in forests, bushes, open pastures, grasslands, mountains and other environments.
Ticks like to bite in places where the skin is thin and not easily detected, such as the neck, behind the ears, and at the base of the thighs. After tick bites, it will constantly release anesthetics, no pain and itching sensation, so the human body often does not feel it.
Reminder: In case of a tick bite, go to the hospital and get it out
Liu Peng reminded that citizens should try to avoid sitting and lying down for a long time in grasslands, woods and other places. If you must enter such areas, you should wear long-sleeved clothes, no sandals, tie your trouser legs tightly or tuck them into your socks, and wear light-colored, smooth clothes.
It is currently the summer vacation, and parents should especially remind their children not to play in the barren grassland and bushes. In addition, in the summer, the dog should also try to go to places with lush vegetation, check for ticks in time after returning home, and regularly deworm pets.
When ticks suck blood, their heads, including mouthparts, are deeply embedded in the skin of the person being sucked. Female ticks that have sucked blood will increase by 80 to 120 times, and it is difficult for the public to remove them completely. If it is pulled hard, it is easy to leave its head in the skin, increasing the risk of infection. Therefore, if you are found to be bitten by ticks, you should go to the hospital in time to remove it, and do not take it yourself. If symptoms such as fever occur, they should be paid more attention to. Close contact with others should be avoided until the cause is confirmed.
