Southeast Asia
Here, with a mosquito bite, you run the risk of contracting a serious illness - Japanese encephalitis. It flows with fever, severe brain damage and is characterized by high mortality.
Africa, South America
Mosquitoes carry the viruses of yellow fever and encephalitis St. Louis. The latter proceeds mostly easily and without consequences, but the patients with yellow fever suffer from severe fever, they fall into prostration and often die without regaining consciousness.
Any tropics
Insects are also dangerous for human life because mosquitoes suffer from malaria (about one million deaths per year among local residents). Causes disease malarial plasmodium (like amoeba) "eating" the red blood cells of a person from the inside. Fortunately, malaria can be effectively treated with quinine drugs, if taken on time or in advance, completely cleanse the body of parasites within a week.
Do not let yourself be stung
Wear clothes with long sleeves and spacious pants of light colors. Dark clothing keeps much more heat, so the more the temperature of your body and the more you sweat, the higher the risk of being bitten.
Clean containers with water (including a bowl for water to pets). Female mosquitoes like to lay eggs there.
Be inside the house at dawn and during dusk, when the air is teeming with mosquitoes. Komarov attracts carbon dioxide, which is released only by living warm-blooded organisms. Means containing 20 percent of insecticide-diethyl-toluamide (DETA) effectively reduce the flair of mosquitoes to carbon dioxide. Treat such products with skin and clothing, and mosquitoes do not feel that you are their potential food.
Against mosquitoes are also effective preparations containing eucalyptus, lemongrass, cetronella oil, sweet orange. From mosquitoes that flew to the flame, electrofumigators will be relieved. But too often it is not worth using them.
If you are bitten:
Clean the site of the bite and apply a cream with hydrocortisone (has anti-inflammatory and anti-allergic effect). Try not to comb the area of the bite: it will only aggravate the itch. Call your doctor if the bite is greatly increased in size (an indicator of an allergic reaction), or you have a headache, fever has risen.
Komarov attracts carbon dioxide, which is released only by living warm-blooded organisms.
Beesweed
Most bees die, biting, and the sting of some wasps is not separated from their torso, and they can attack four to five times in a row. Wild bees attack collectively.
Do not let yourself be stung
Bees like bright colors and sweet smells. Do not apply perfumes with sweet floral or floral-fruit aromas before walking into the forest, field or near the apiary.
Eat and drink sweet indoors. Never touch the beehive in an apiary without a special protective net. Avoid swarming bees - if you violate their unity, the risk of attack multiplies.
If you are bitten:
Remove the stinger with tweezers or fingers as quickly as possible - on the sting is a container filled with poison. Fully poison is absorbed in about a minute. Wash the bite with soap and water. Attach the ice.
Immediately take inside antihistamine (against allergies), or a drug with ibuprofen (a component with analgesic, anti-inflammatory and moderate antipyretic effect). If you have a sharp reaction to a bite, show your doctor.
Ticks feel the approach of a person by changing the temperature, the movement of air and the vibration of the soil.
Clamshells
Ticks live in parks, courtyards, in the forest and on the banks of rivers. They hide on grass and twigs of bushes. The mites have a pet eye, but they respond well to temperature, air movement and soil vibrations when a mammal or a person approaches. The mite clings to the animal's fur, clothes, why it gets to the open areas of the skin and sucked. Ticks carry tick-borne encephalitis.
Europe
Encephalitis proceeds very easily. A slight rise in temperature, malaise, and a couple of days you are healthy.
Urals, Siberia, the Far East
Heavy forms of encephalitis with high mortality and serious complications (head and spinal cord). Pain pattern: muscle pain, multiple vomiting, strabismus, epileptoid seizures, paralysis, disorientation in space, etc.
Do not let yourself be stung
On a walk wear light clothes from a durable fabric with long sleeves, closed shoes, close your head, pants, thread boots on bootlegs, shirt - into trousers. On such clothing, the mites are visible immediately, and you quickly remove them before they attach themselves to the skin.
Ticks attract blood and carbon dioxide, excreted by living beings. Insecticide DETA, which is effective against mosquitoes, also protects well against ticks. The action of another powerful insecticide, permethrin, is directed against ticks and lice.
In advance (at least 3 months before traveling to a dangerous region), make vaccinations against encephalitis. From the moment of the first vaccination until the emergence of resistant immunity takes about a year, during this time it is necessary to make 2 more inoculations: a month and a year after the first.
If there are no doctors nearby, remove the mite yourself - just with tweezers! Grasp directly at the attachment point, gradually swing and very gently pull. You can not grab it in the middle or "by the tail," the head or proboscis can come off and stay in the skin, which is very dangerous.
Remove the tick or even part of it in no case - they are needed for analysis, whether the tick was a carrier of encephalitis and whether there is a risk of getting sick. Take the remains to the laboratory and diagnostic center, or even better to the point of seroprevention.
