Acute Hepatitis 4

How long does this stage last??? it seems like FOREVER (maybe a BUG). Also, is it fatal? It cant be cured with nano-robots unfortunately :(

Edit: It isn't cured by the nano-robot treatment at Haggerty's clinic for some reason, but it was finally cured by using a scavenged nano-robot kit. This may be a bug.
