According to international statistics, more than 700,000 people die every year due to mosquito bites , and mosquitoes rank first among the animals that cause human death.
As summer comes, a new round of "concerts" begins to play, "Buzz, buzz--" the melody of summer lingers in my ears.

Let’s learn together today...
What are the dangers after mosquito bites?
The lethality of mosquitoes is divided into two types:
The first type is to absorb blood, which is less harmful.
Many people will have allergies in their local skin after being bitten by mosquitoes, such as redness, swelling, pain, and itching. After scratching with their hands, the skin will also experience severe conditions such as ulceration and infection.
The second type is to spread fatal diseases and is highly lethal.
Mosquitoes top the list of 15 most deadly animals to humans, and their number of harms to humans each year exceeds the sum of all other animals on the rankings.
There are three generas of mosquitoes that are closely related to human health, namely Culex genus (domestic mosquito), Anopheles (malaria mosquito) and Aedes (Aedes mosquito) each in my country.
When mosquitoes suck human blood, different categories of mosquitoes will cause different diseases and clinical characteristics.
Usually Anopheles mainly transmits malaria , and the clinical characteristics will be manifested as fever, sweating and intermittent chills; Culex mosquito transmitted by biting humans is unclear consciousness and high fever; Aedes mosquito sucks human blood and can spread a variety of diseases, such as dengue fever , yellow fever and chikungunya disease. The main transmission vectors are Aedes mosquito.
The bigger the mosquito bag, the more toxic it is?
After being bitten by a mosquito, the size of the mosquito bag on the body is closely related to the strength of the individual's immune system mechanism and has nothing to do with the toxicity of the mosquito.
can be unscathed for people with strong immune systems after being bitten, but most people will have physical reactions, mildly showing raised mosquito bags and obvious itching. The skin lesions are manifested as erythema, papules , wind balls and other symptoms.
For people with weak immune systems, especially those with sensitive constitutions, after being sucked in blood, a large amount of histamine and cytokine will be released, and blisters, plaques, ecchymosis, swelling and pain will appear. Due to the intense reaction of symptoms, it will take a long time to completely relieve it.
In addition, scratching with hands will increase the release of histamine in the organic nitrogen-containing compound, resulting in tissue damage or inflammation, resulting in local tissue edema.
When you feel itchy, you can apply mint cream and floral water in time to relieve it, instead of choosing to scratch.

What kind of blood do mosquitoes prefer to suck? Is it related to blood type , whether the blood is sweet or not...?
Mosquitoes are extremely sensitive to factors such as CO2, calories, volatile chemicals, etc., and their sense of smell can quickly detect and accurately locate these substances. The secretion of these substances is closely related to personal metabolism, such as the body's metabolic products urea , lactic acid, fatty acids, etc., so when you emit large CO2, frequent sweat secretion, and vigorous body metabolism, it is easier to get the favor of mosquitoes.
Mosquitoes mainly identify and find the blood-sucking object through the smell in the air, so whether they are recruited is not directly related to the blood type.
Is it useful to pinch the cross in the mosquito bag?
Answer: Useful - Psychological effect, mainly to utilize the human body's pain transfer.
Imagine if you pinch your nails hard on the mosquito bag, your subconscious will feel pain and you won’t care about the itch. In fact, the itchy feeling has not disappeared, it’s just that the pain overshadows the itchy feeling, which is entirely your own psychological effect.
Correct treatment tips:
① When it comes to itching, you can use alkaline substances to neutralize it, such as baking soda , and you can use soapy water at home, which has a very good anti-itchi effect.
In addition, applying salt water or rinsing itchy areas can soften the lump and achieve the effect of removing pain and relieving itching.
②Do not scratch with your hands, especially on the lumps on the skin, otherwise tissue damage will occur and lead to infection.
Because itchy scratching may speed up the blood flow rate in the capillaries, you can spray some flower dew water in a small range. Most flower dew water contains alcohol. Large-scale use will cause symptoms of alcohol allergy, especially those with sensitive constitutions who use it with caution. Once there is a sting, you should stop using it immediately and seek medical treatment.

③ For mosquito bags on the skin, cold compress can be used to relieve pain, such as wrapping frozen drinks in a towel to float on the affected area. Apply external drugs such as desonide cream, elosone cream, etc. at home.
④ When mosquito bites red and swollen, first use ice cube cold compress, and then use topical drugs according to the doctor's instructions, such as 1% mint calamine lotion or 1% mint cream.
⑤ When the bite shows obvious infection, anti-infective treatment drugs, such as mupirocin ointment, should be used in time. If it cannot be relieved, seek medical treatment in time.
How to avoid being bitten by mosquitoes outside?
Remember the three-word formula of "avoid, drive away, and destroy".
1 - Avoid

Apply cooling oil, wind oil essence, mosquito repellent, etc. in advance when exposed parts of the body in the wild.
2——Hydrilling
Select the flower dew water and mosquito repellent containing DEET , EDIN ingredients. When using mosquito repellent products, the more the medicine, the better. You can choose to use it in a small amount multiple times during outdoor activities.

mosquitoes, like darkness and fear light, if it is outdoor activities at night, lighting equipment should be brought with you to avoid it.
3 - Destroy
Since mosquito eggs, larvae and pupa all live in water, their growth and development cannot be separated from water, so the place where mosquito breeds and reproduction is blocked from the source, mosquito repellent is selected to keep the ground clean and free of water accumulation, do a good job of environmental sanitation, try to remove its growing land, and strengthen efforts to protect the natural enemies of mosquitoes, such as bat , swallows, dragonflies, spiders, geckos, frogs, etc., so that they can eliminate mosquitoes, and use biological control to avoid environmental pollution.
