According to the deputy, such data are "unscientific and irresponsible."

“Yes, Russia has West Nile fever, the first cases of which were recorded in 2009. This disease did not suddenly appear, we know about it. Regarding the spread of Zika and Chikungunya viruses, this situation is also under our control, ”Onishchenko said.

For his part, Viktor Maleev, adviser to the director of the Central Institute of Epidemiology of Rospotrebnadzor for scientific work, in an interview with the NSN, called the messages "exaggeration."

As the expert explained, in Russia there are no conditions for the survival of mosquitoes undergoing tropical fever.

“Some mosquitoes do not spread. In Egypt, there is a mosquito that suffers yellow fever, but we don’t have it yet. Unrealistic, that could be. If it gets warmer in 20-30 years, then yes. And so, in general, there is a known threat, but on the other hand, means are now being developed to combat mosquitoes, ”he said.

Earlier, Rospotrebnadzor denied data on dangerous mosquitoes in southern Russia.
