<h1>Ticks</h1>
A few days ago, a 2-year-old child in Yangzhou, Jiangsu Province, had an unexplained fever and vomiting, and tong tong's mother found a tick in its head. After preliminary determination by the doctor, the child may have had an adverse reaction after being bitten by a tick.
✖ Rumor: It is rumored on the Internet that "someone was bitten and died of a high fever for 10 days!" The news that this tick bite kills.
✔ Truth: Being bitten by a tick, handling it correctly, seeing a doctor in time, most of the situation is controllable.
<h1>What is a tick? </h1>
A tick is a bug that needs to suck blood from other animals to survive and reproduce, about the size of a matchstick head, and has eight legs. When not sucking blood, it is the size of a grain of rice, and when it is full of blood, it has a fingernail cap. There are some ticks that can parasitize not only on animals, but also on humans. As a result, there have been reports of tick bites on people who go to the wild or pass through the lawn.
<h1>Is a tick bite really that bad? </h1>
The "mouth" of ticks has a complex structure and some "barbs", which cause people or animals to be bitten and difficult to remove directly. Therefore, the most common consequence of being bitten is a skin infection in the corresponding part.
When ticks bite and suck blood, we may not feel much pain, but because the claws and suborgural plates simultaneously penetrate the host skin, they can cause local congestion, edema, acute inflammatory response, and can also cause secondary infection.
Ticks are not very toxic on their own, but they have blood-sucking properties, and if ticks live in harsh environments, they may spread some serious diseases. For example, in areas with high endemic epidemics, or during periods of active epidemic viruses such as spring and summer, ticks can transmit some serious diseases, some even fatal, common such as Lyme disease, hemorrhagic fever and so on.
<h1>How can ticks be prevented? </h1>
Avoid going to forests and thickets of grass with leafy shrubs;
City dwellers should be wary of whether there are ticks on the skin surface of pets or other animals;
In the wild, wear long-sleeved trousers, and tie the legs of the pants, wear hats and other protective gear, and reduce the exposure of the exposed parts;
Insect repellents such as DEET or octenin are used on exposed skin.
<h1>What should I do if I get bitten by a tick? </h1>
1 First of all, to double check:
Usually tick bites are painless, and only a few people cause obvious allergic reactions, so people are often unaware when they are bitten;
Ticks may parasitize anywhere in the body, especially in the folds of the skin, such as the scalp, behind the ears, the neck, the armpits, the popliteals, the wrists, the groin, etc.;
There are also some ticks that will attach to clothes, shoes and hats, and it is necessary to carefully find the attached ticks;
If you have taken children or pets to the lawn or the wild, also check them carefully;
Even if no tick bite is found during the examination, if you go out through the epidemic area, you should always observe the physical condition, such as fever and other symptoms, should be vigilant about related diseases, and once you find relevant symptoms, you should immediately go to the hospital for treatment.
2. After the tick is found:
Whether on the surface of the human or animal body, or on the surface of objects such as clothing, do not touch it directly with your hands, let alone crush it, you must use forceps or other tools to clip it;
If you accidentally come into contact with ticks, especially the outflow after ticks are squeezed, disinfect them in time.
In the method shown in the following figure, clamp the tick that bites on the skin with forceps and remove it vertically upwards:

<h1>After removing the tick:</h1>
Topical disinfection with alcohol or other disinfectants, and in severe cases, antibiotics may be required;
If conditions permit, a few removed tick stumps can be kept in an airtight container, and in case the condition of the bitten person worsens, these limbs can be used as a reference for doctors to better diagnose and treat;
If symptoms such as fever, swelling and pain at the bite site, ulceration and erythema appear, it is necessary to seek medical attention in time so as not to miss the best time for treatment.
Overall, ticks are not as scary as the legend goes. It will not burrow into the human body, nor will it lay eggs on the human body, even if it is bitten, as long as it is correctly handled, closely observed, and timely medical treatment, the physical harm to the person is not so great.
