Dear Sasuke-kun,
SNK-9 was a stellar success!
Thanks to the help of Iwa and Suna, plus the volunteer shinobi who allowed themselves to be tested, we were able to come up with the vaccine for Rabbit Pox! Turns out, the pathogen we encountered was an ancient strain that was revived during the war. It was unfortunate, and it was devastating.
Actually, Kurama (Naruto's 9-tailed friend) was the key to whole thing! Naruto caught the bug on a mission with Sai. He was a very helpful test subject, and a very quiet one at that. It turns out, tailed-beasts have immunity to these pathogens and with Kurama and Naruto's healing chakra, I was able to synthesize a vaccine. I want to provide the explanation for this... but of course information security is always something we need to think about.
How do you like the name I gave the bacteria? I thought since I was caused by the return of Kaguya, it would be a clever thing to name it Rabbit pox.
I'm sorry I haven't written in while. I know you're travelling right now, but I hope you are in good health. Don't worry, I am taking care of myself, but I can't help but worry about you. I hope that where ever you are, you are in good hands.
Sincerely,
Sakura
