The dangerous disease-carrying Asian tiger mosquito that? Are there treatments? Can the spread be prevented?

In many media reports about the danger that is the tiger mosquito spread dangerous diseases in Europe could. Some virus species use mosquitoes as a host or as a vehicle for their dissemination. The pathogens are taken up by the mosquito with a blood meal and the next stitch passed through the saliva. So the immigrants from the tropics of the Asian tiger mosquito, potential carriers of dangerous infectious diseases such as dengue and chikungunya fever. The Asian tiger mosquito bites as a special mainly during the day, is often disturbed and changes to the saturation of one or even several other hosts. This is also a place where the transmission rate is particularly high.

Dengue fever

Dengue diseases are considered the world’s most common, transmitted by mosquito virus infections. According to WHO estimates disease annually worldwide about 50 million people have dengue fever. After an incubation period of 3-10 days, the symptoms of dengue fever are similar to the flu. It occurred at high fever, headache and body aches and possibly skin rashes. Dizziness, nausea, sore throats, coughs and colds can follow. After an interim poverty complaint follows a renewed fever. After about 2 weeks cures from the disease. Especially in children or in another infection can occur, however, very serious complications that make intensive medical care required. So far there is no drug to treat dengue fever. So you can only alleviate the symptoms. Scientific studies of a vaccine to run in Southeast Asia, which will be ready for the market certainly need a few more years. Dengue fever is a notifiable infectious diseases.


Chikungunya fever

Even when it comes to chikungunya fever high fever. Typical of the disease are strong links and joint pain that can persist in rare cases even for months. The incubation period is 3-7 days. Danger does not exist. Normally sounds from the disease after 1-2 weeks and leave lifelong immunity. So far there is no specific treatment, vaccine development is at an early stage. 2007 in Northern Italy was an outbreak of epidemic in the affected approximately 200 people. The trigger for a sick tourist was believed that should have brought the disease from India. Also for the chikungunya fever in Germany there is mandatory reporting.

Studies show that climatic factors may have influenced the spread of infectious diseases. In various fields such as medicine, microbiology, entomology and climatology) is an interdisciplinary research. How to Create the Senckenberg scientist German Entomological Institute (SDEI) together with those of the Bernhard Nocht Institute for Tropical Medicine (BNI) is a mosquito map of Germany. In high-security laboratory is then examined how viruses are transmitted. So the gathering of many data is needed before reliable conclusions can be made about relationships. In Switzerland, it is assumed that most of the breeding places of mosquitoes Tiger on private land are in some standing water from flower pots and saucers, and rain barrels. Since natural garden ponds predators of mosquito larvae contain these waters will be evaluated as a positive use. Vessels with fluid retention should be regularly emptied and turned upside down.
