Mr. Song, 62, is a fishing enthusiast with a strong sense of protection, wearing long-sleeved trousers when fishing, but he was still bitten by two ticks. When Mr. Song found out, he pulled out the tick himself. He knows some knowledge of ticks, knowing that if the ticks are not cleaned and remain in the body, they may become ill in the future.
So after being bitten for three days, Mr. Song was not at ease, went to the hospital's infection department for examination, fortunately the relevant examinations were normal, the doctor told him to observe for a period of time, if the fever is urgent to the hospital.
Lingling, a 3-year-old baby girl, was taken by her family to Hengdian to pick lotus puffs, and after returning home to take a bath at night, her mother found that she had a black thing the size of a green bean on her arm, and her first reaction was ticks. The family immediately took Lingling to the hospital, and after the doctor smeared it with alcohol, he used tweezers to pull out the ticks that were still alive.
Ms. Zhou, 35, went to the hospital to remove the tick after being bitten by a tick. She was very puzzled, she was busy at work, and she didn't have time to go to the field. The doctor asked her if she had ever been exposed to a long-haired pet, and Ms. Zhou remembered that she had a sheepdog at home, and she often brought her dog to the community in the evening, and it was likely that ticks spread to her through the dog.
It is understood that ticks are active in April to October, due to less summer dress, exposed limbs, more likely to become tick targets. The reporter combed and found that in recent years, the reported tick incidence period is often in July and August.
Wen Danning, director of the Department of Infectious Diseases of Jinyintan Hospital, explained that ticks carrying the virus bite the human body, which will introduce the virus to the human body and cause disease, and serious will cause the patient to die of multi-organ failure, but less than 10% of the ticks carrying toxins. Therefore, there is no discomfort in the half month after being bitten by ticks, such as fever, rash, etc., and the public should not worry.

Ticks may carry pathogenic viruses
Although the tick is called an insect, it is not actually an insect, it has eight legs, is a relative of spiders, and belongs to the animals of the arachnid tick mite suborder. There are more than 800 known species of ticks.
Ticks are associated with the spread of many diseases. Ticks can transmit 81 viral, 31 bacterial and 32 protozoal diseases such as Lyme disease, maculella fever, forest encephalitis, and hemorrhagic fever. However, in most cases, being bitten by a tick is similar to being bitten by a mosquito, and there will be no serious consequences.
The most common skin infection after being bitten by a tick is because the tick's blood-sucking mouthparts are complex and have barbs on them, and once the tick that is sucking blood is improperly removed, it is likely to break its mouthparts in the skin.
In 2010, there were many deaths caused by "tick bite disease" in Henan, Hubei, Anhui and other places, which aroused widespread concern in society. The Chinese Centers for Disease Control and Prevention later determined that the deadly tick carried a new type of Bunia virus, a disease caused by the virus that was designated fever with thrombocytopenia syndrome.
Tian Junhua, an expert at the Institute of Vector Biological Control of the Municipal Center for Disease Control and Prevention, said that a total of 22 tick species have been found in Hubei Province, mainly distributed in high mountains and hilly areas, including Huangshi, Yangxin and Daye in the Mufu Mountains, and Huangpi, Xinzhou, Huanggang, Suizhou, Xianning, Xiaogan and Dayu in the Dabie Mountains. In addition, ticks are distributed in a small amount in Huazhong Agricultural University, Jiefang Park, Wuhan Cigarette Factory and other areas in the central urban area of Wuhan, and the low density does not pose a threat.
Ticks carry viruses are divided into two categories: highly pathogenic and lowly pathogenic, and the new Bunia virus is a type of highly pathogenic virus, but experts emphasize that the proportion of ticks carrying highly pathogenic viruses is extremely small.
It is recommended that the public pull out the unknown insects on the body and do not throw them away easily, but can put them into a sealed plastic bag or bottle and refrigerate it in the refrigerator. In case of birth symptoms, it can help specialists find the cause more easily.
How to prevent:
Find ticks don't pinch, pull, pluck
"After being bitten by a tick, it may not be perceived immediately", explained the director of the Infection Covin Danning of jinyintan Hospital in the city, the tick bites the skin after sucking blood, the length of the blood sucking time is related to the type of tick, some can stay on the surface of the body for 1 to a few days, and the pain is not felt when the bite begins.
Van Denning said that although ticks are not shallow, they also have their own weaknesses. It can't jump or fly, the range of motion is limited, generally only tens of meters, mainly "hidden" in the grass, woods, waiting for the opportunity to attack the "target", so usually will not run to the home. Ticks are also temporary parasites on the surface of a variety of vertebrates. Densely haired animals such as sheepdogs are also excellent hiding spots for ticks.
At present, it is the peak tourist season, reminding the public to pay attention to tightening the trousers when going deep into the grass, woods and other places, and applying repellents (DEET, DEET, etc.) in time to the exposed skin. In case of tick bite, do not pinch, drag, dial, the correct way to deal with it is to quickly find the nearest regular hospital, disinfect at the bite site, local anesthesia if necessary, anesthesia can be removed only after the anesthesia is effective, the tick can be removed with forceps, pay attention to the tick mouthpiece in the barb can not remain in the body, such as the mouthpiece into the skin should be surgically removed. Pets in the home, avoid bringing in places where ticks may be hidden.
