Hungry for blood and endanger health. Season ticks and mosquitoes begin!

Hungry for blood and endanger health. Season ticks and mosquitoes begin! In spring and summer, increasing the risk of a bite or sting various insects. Most beset us, ticks and mosquitoes. While in the former parasite remains the same spectrum transmitted diseases, mosquitoes us begin Caster yet unknown disease. Should we be afraid?

Insidious "anesthesiologists"

If the tick is definitely true that the danger is proportional. Although these parasites length is usually only a few millimeters, can transmit life-threatening illness. Tick ​​and mite is among the arachnids. Along with spiders has combined number of limbs. How is it possible that a person does not notice when he was bitten by this parasite? Ticks in the wound emit chemicals soothing pain . Part of their tactics is the fact that within half an hour after the bite around creates a structure similar to putty. This hinders their easy removal. Ticks are able to climb bushes and trees to a height of one and a half meters. They are familiar with Haller's organ which senses heat, humidity and carbon dioxide produced okolojdoucími animals. Contrary to legend, however at people or animals do not they jump. They reach out to them and limbs collected on them.

Encephalitis remains a threat

Tick-borne encephalitis sickened with us last year, 351 people. The virus of this disease include two subtypes - our Eastern and Central Europe.

The first is the originator of the Eastern (Russian) spring-summer encephalitis, which typically has a biphasic waveform. It is a bit heavier compared to Central European species. According to studies often affects older people and twice as vulnerable as men than women. After an incubation time of 10 days, shows the following symptoms: fever, headache, vomiting, chills, photophobia.

Following the loss of sensitivity, convulsion and disturbance of consciousness . Only 20 of the 100 infected die of the disease. In 60% of patients with symptoms of nervous system involvement.

Central second type of encephalitis also takes place in two stages. In the first stage, appearing nonspecific symptoms, such as headache , fever, malaise and nausea. Approximately 2/3 of people followed by recovery. In the remaining third, however, develops encephalitis and will result in disorders of consciousness, disorientation or inflammation of the pharynx. Against the virus can be prevented by vaccination, which is effective against both its subtypes. Vaccination rates among us, however, still is only 30%.


Lyme disease, many people transition

Unlike encephalitis borreliosis is a bacterial disease caused by Borrelia burgdorferi microbe. It is located in the gut parasites. In the Czech Republic are reported each year around 4,000 cases of the disease. Symptoms that accompany it, are usually nonspecific. It includes: fever, pain in muscles and joints, fatigue.

Very typical manifestation is called. Erythema migrans, a flare with the image of the target. May disappear and appear again in another place. Against the European type of disease, unfortunately, there is no effective vaccine, but antibiotics help. The illness tends to have a different course, sometimes it may not even notice question or vague symptoms does not attach importance.

And what about mosquitoes?

With mosquito bites probably has the experience for everyone. Although this creature spike spike thinner than a tick, do not emit any wounds numbing agents. Therefore, we feel the pain of the attack. As with ticks, mosquitoes have interest in the human blood. Worldwide known over 3,500 kinds of mosquitoes, of which 104 were reported in Europe. In addition to the transmission of dangerous diseases, although mainly concern the countries to the south of Europe, is increasingly present also allergic to mosquito bites. This is probably related to the arrival of new species that spread to us from the south. As in southern Europe these kinds settle, there are also new diseases. In Italy, cases of dengue fever and chikungunya. Yet there is no need panic, this is only exceptional cases.
