With the arrival of midsummer, "ticks" (commonly known as grass creeper) began to be highly active in some areas, and related diseases also occurred frequently, which was easy to threaten lives and could not be avoided. According to surging news It is reported that recently, in Huangchuan County, Xinyang City, Henan Province, three elderly people died of "fever with platelet syndrome" (commonly known as tick disease), and another person is under treatment. All of them had cleaned up an infected person who had died before**
It is reported that an old man in the village was bitten to death by ticks last year. On May 5 this year, Huang Cheng, an old man over 70, was in critical condition after being infected with tick disease and died unfortunately.
The next day, according to local customs, many old people dressed the deceased in birthday clothes. After the funeral on the 11th, the 80 year old Yang soon developed symptoms of fever, fatigue and pain all over the body . During the night hospitalization on the 19th, he developed convulsions, incontinence of urine and urine, blurred consciousness and so on. He died early on the 20th. However, Yang had been very good before and almost never took medicine.
Huanghua, a 66 year old brother of Huangcheng, also suffered a similar situation after the funeral and died on the afternoon of the 26th.
Zhanglihua, Huangcheng's wife and brother, visited Huangcheng twice, and was later diagnosed with tick disease. He is currently receiving treatment.
According to the current situation, several old people may have been infected during the process of cleaning and dressing the deceased. At that time, there was a cannula on the body for rescue blood transfusion, which was accidentally broken during cleaning, and the blood in it splashed on several people**
Virologist changrongshan believes that the residual secretions, excretions or contaminated items on the remains of the deceased may cause contact transmission of infection**
It is understood that the larvae, nymphs and male and female adults of ticks suck blood. At the same time, they are temporary parasites on the body surface of many vertebrates. They are the vectors and storage hosts of some zoonotic diseases. The hosts include terrestrial mammals, birds, reptiles and amphibians. Some species invade the human body**
Most ticks have a wide range of hosts. For example, the hosts of Ixodes persulcatus include 200 species of mammals, 120 species of birds and a few reptiles, and can invade human body.
Ixodes usually invade the host during the day and take a long time to suck blood, which usually takes several days. Soft ticks usually invade the host at night, and the blood sucking time is short, usually from a few minutes to an hour.
The blood sucking capacity of ticks is very large, which can swell several times to dozens of times after full blood in each development stage, and the female Ixodes can even reach more than 100 times
Ticks are widely distributed in China, mainly in Henan, Hubei, Shandong, Anhui, Liaoning and other provinces, especially in Xinyang area of Henan Province, which is a high incidence area, mostly concentrated in April to October every year
The ticks in Xinyang mountain area are called Ixodes persulcatus. They live by sucking blood. They usually lie dormant in the grass and plants in shallow mountains and hills, especially in the back of tea. Xinyang City is one of the top ten famous teas in China. Most tea farmers have scars on their legs after being bitten by ticks.
Since 2007, tick disease has occurred frequently in Xinyang Shangcheng County. In july2010, a large-scale tick bite death event occurred in Shangcheng County, which attracted national attention. 94.2% of the patients were farmers, mostly over 50 years old, and the incidence was concentrated in shallow mountains and hills
In 2010, the China Meteorological News published an article pointing out that the mall is located at the northern edge of the north subtropical zone and is characterized by "high temperature and high humidity" in midsummer.
There are many mountains and hills, with special geographical environment and rich water, animal and plant resources. In addition, the mall is located at the north foot of Dabie Mountain, with little sunshine, which provides superior conditions for ticks to survive.
