New 'mutant' blood-sucking tick has been discovered in Russia
Siberia has been hit by an invasion of blood-sucking ticks including a new and deadly mutant variety. The mutant ticks have been found in several regions of Siberia. They combine the worst qualities of two common types of Russian tick - Ixodes persulcatus, the taiga tick, and the malicious Pavlovsky. The scale of the swarm has left some hospitals already stretched with rising numbers of coronavirus deaths.
