Virus, virus, virus again!
Since the outbreak of Xinguan, the word “virus” has filled all people’s lives, and every new news has drawn the hearts of the public.
Chinese experts have identified and named two new infectious viruses that live on a common insect in our lives.
A team in China has discovered two new viruses that cause disease in humans
On February 18th, by foshan Liu Quan, professor at the school of science and technology, Inner Mongolia forestry general hospital dean wang wei and sun yat-sen university, zhongshan school of Medicine, professor chan g lead the research team, in Nature Medicine, published a new study, researchers from people tick bite injuries identified a new kind of tick-borne virus, after people infected by the virus, the symptoms of fever, headache may occur.
High-throughput sequencing of the blood of a patient with an unexplained fever from a tick bite revealed that the virus was similar to known Nero viruses, but in a separate branch sequenced by its genome.
Retrospective analysis of other cases showed that all patients infected with the virus had a history of tick bites, and their clinical manifestations were fever, headache, fatigue, dizziness and other symptoms.
The researchers named the virus Pine Ridge virus.
As early as 2017, a research team that Liu was part of found that during surveillance of tick-borne diseases in China, a patient from Alongshan had a severe fever of unknown etiology, but the common virus was not isolated.
Taking blood samples from this patient, the researchers compared other patients with a history of fever, headache, and tick bites to identify an unknown segmented RNA virus, which the researchers named Arongshan virus.
The study, published in the New England Journal of Medicine in 2019, noted that researchers also detected Arongshan virus in other patients with fever and headaches, as well as ticks and mosquitoes in the area.
Two, small tick, but great harm
Spring blossoms, all things recovery, dormant insects in the dark, began to look for blood foraging.
Don’t underestimate this bite. A few minutes bite can kill you.
It is reported that Mr. Zhu (pseudonym), who lives in Qingdao, has been hospitalized in Qingdao Sixth People’s Hospital for more than a month. Mr. Zhu recalled that when he was first admitted to the hospital, he still felt a little scared. “Fortunately, I was admitted to the hospital for examination, otherwise my life would have been gone…”
It turned out that Mr. Zhu was a forest firefighter. One day in the middle of May, Mr. Zhu felt pain and itching on the inside of his right leg. He held his leg up and found two more scars, just like mosquito bites.
At first, Zhu thought it was a fierce mountain mosquito bite and ignored it. However, a few days later, he suddenly developed a high fever.
“His condition was very serious. He had a platelet of 32, which was very low.”
Zhu’s family took him to the hospital, where he was found to be dangerously ill, and later checked out by the hospital, where he was diagnosed with infection from a pathogen bitten by ticks.
In fact, in China, there are a large number of patients admitted to hospital due to tick bites every year, and in 2020 alone, there were a number of cases of tick bite deaths in various provinces.
In June 2020, Wuhan Evening News reported that 72-year-old Li A Po fell into a coma after being bitten by a tick. Although she received active treatment, she eventually passed away due to the decline of multiple organs.
In July of the same year, five cases of severe tick bite were admitted to Nanjing alone.
Jinzhai County said 23 ticks have bitten hospitalized patients, including five deaths.
In August 2020, a 12-year-old boy in Beijing was admitted to hospital with pain and itching near his ribs.
Ticks belong to the order Paracariidae, Ixoidea. They look a little like the size of a rice worm, but they are no more “mild” than a rice worm.
Ticks belong to parasites, which feed on blood, can live on the body surface of a variety of vertebrates, and are the vectors and storage hosts of zoonosis.
Every year from May to July, is the tick breeding period.
Ticks can carry a variety of viruses, bacteria and protozoa. After being bitten by ticks, they can cause diseases including tick paralysis, tick bite fever, novel Bunyavirus infection, Lyme disease, forest encephalitis, Xinjiang haemorrhagic fever and so on. Severe diseases can even cause death.
Do not do this after a tick bite!
What do you do if you find a tick biting you?
Wait a minute!
Do not act on impulse, because after a tick bites a person, it is not easy to completely remove, when it is sucking blood, it can embed the whole mouth part into the skin, at the same time secreting harmful substances, if forced hard drag, it is easy to cause the mouth part to stay in the skin, causing serious infection.

Getting a tick requires the help of tools, starting with a pair of tweezers, holding its mouthpiece (located on the head) as close as possible to the skin, and then pulling it out vertically so it doesn’t break.
Or you can drop iodine tincture, alcohol or ethanol on the surface of the tick, and apply turpentine, vinegar, etc. on the head of the tick to make it fall off by itself.
Here small nine remind a bit: if not sure, do not pull out tick by oneself, should go to the hospital as soon as possible, let the professional doctor to operate!
Ticks usually lurk in grasslands and forests, with high incidence in spring and summer. Although the weather is suitable for field trips, it is also necessary to pay attention to protection. If you need to enter the jungle, grassland or deep mountains, it is recommended to wear long-sleeved clothes, tie up or tuck pants legs into socks or shoes, and wear a good hat to prevent insect bites.
Bare outside the skin, you can also apply the right amount of repellent agent.
