CBC Test; normal after 4 yrs infected Dr. Holodniy,A friend tested HIV+ 4 years ago. He has chosen to abstain from taking any medications (due to personal reasons). Recently, he took a CBC test and everything showed up as normal. Why is that? Shouldn't his WBC count be a little low?
Encountering a Shiny Legendary or a random shiny Tentacool have the same rate of 1 in 4,096. However in the wild the chance of a Shiny Pokemon with Pokerus is 1 in 178956971. Your Latias is very rare as it is Shiny but also has Pokerus. However the Latias probably had Pokerus infected onto it via another Pokemon. There is also a possibility it was hacked too.
You can get pokerus by battling a wild pokemon that has the infection. The virus is about as rare as a Shiny Pokemon. Once you catch it, you'll see the letters PKRS in the menu section of the stats screen. The next time you go to a pokemon center Nurse Joy will tell you that your pokemon has caught Pokerus. For your other pokemon to catch it, you must keep the infected pokemon in your party with other Pokemon and battle any Pokemon.
