How many contagious mosquitoes are there?
A development has been created that captures the viral threat of mosquitoes

If mosquitoes circling in a particular residential area begin to carry a particular viral disease, local authorities and health authorities should know about it as soon as possible – especially this problem is relevant for African countries. However, traditional methods for determining the virus in a particular territory take up a lot of space and time to check, and the results usually wait a whole week. That is why virology specialists from Purdue University in Indiana, USA, have presented a new unique development that determines the presence of a particular virus indoors or outdoors through a special sensor system.
The device is an electrode wrapped in a special material with a high proportion of surface zoning – when a biological sample of a mosquito carrier of a virus gets on the material, the DNA or RNA of the virus is attached to it. This creates changes in the operation of the electrode, determined by sensors – they are the ones that notify users about the potential presence of a virus in the monitoring area.
A snapshot from the Purdue researchers press release developing a device that detects mosquito-borne diseases, giving health officials time to take action - VM.
To be more precise, the sensor system measures the degree of changes in the electrode, thus pointwise indicating how dangerous a viral situation is potentially unfolding. In addition, the development makes it possible to determine the strains of most viruses carried by mosquitoes, with the exception of malaria so far, due to its difficulty of capture, but soon this will not be the case. Moreover, specialists are planning to modify the initial model of the device somewhat, adding an additional system of sensors and sensors for activating the study of strains.
According to the head of the research project, Leah Stanciu, the development of such a device does not involve the use of any expensive or rare materials, and therefore costs the team of engineers a fairly small amount. Given the much higher level of efficiency of this development in contrast to traditional methods, it becomes clear that soon the development will become even more widespread, accessible and widespread – it remains only to wait for the end of laboratory work related to it.
