The rise comes as human parvovirus B19, a unique virus that infects folks solely, can also be experiencing an uptick. Well being alerts from the CDC observe rising exercise throughout Europe and the US, tracked via elevated take a look at positivity and antibody detection, Contagion stories.

However veterinary consultants emphasize that B19 does **not** infect pets, a distinction the CDC makes clear in its public steering.

Why the Spike Is Occurring Now
