The last that I heard, the newer strain of parvo, which is the 2c the post from trcy mentioned, is not like what the facebook post describes. Given the way that the one puppy is described in passing I would have chucked it up to poison or distemper and not parvo. The current strains of parvo hit rapidly dividing cells first, and the most rapid in dogs who are no longer in utero tends to be the bone marrow and the intestines. They're constantly active, always making new cells. If a puppy is younger than 8 weeks old when they get parvo it has been known to cause cardiac problems and a quick death, so that wouldn't be new in a younger puppy.
If that is just a facebook remark that someone has mentioned, I'd be taking it with a grain of salt and looking for more credible sources to say that something has happened that seems to be spreading. The mode of action is so far from what parvo generally does, I would imagine them considering distemper (which does have a neuro portion to it) or some kind of poisoning more than just parvo. Cluster seizures can cause a huge temperature spike, which can send an animal into DIC, which causes the bleeding, bruising and eventual total system shut down and death.
Too little definitive information to take it 100% seriously, IMHO. Perhaps just be cautious about where your dog goes if you are in that area and wait to see if more reports come up. Generally speaking an outbreak of anything that causes a lot of sickness/death will end up in the news. We had to do a public service announcement one year about parvo because it was just so bad instead of a handful of cases a month, we had easily pushing a dozen a week.
