Tigers have been in danger for a long time and if we didn't help them, they would not have survived. They are going through the dangers of poaching and deforestation. But Asian tigers now face the threat of a virus that is carried by dogs known as canine distemper virus (CDV). CDV is a close relative of the measles and as evolved to not only infect dogs, but many other animals, including the tiger. The last time CDV has caused much damage was before the end of the thylacine, also known as the Tasmanian tiger. The tigers are in danger from a virus that is very hard to stop. The fate of the tiger cannot be the same as the thylacine.
