Even if a place calls themselves a sanctuary, they are not legitimate if they offer direct contact with wild animals to visitors. Please don’t support these places. Also, yet another reason primates are NOT pets.
A common human virus proved fatal to lemurs who were used in a yoga class.
A groundbreaking study has confirmed the first molecularly verified cases of human herpes simplex virus type 1 (HSV-1) in lemurs, leading to a tragic outcome for four privately owned animals.
Veterinary researchers at the University of Florida investigated the deaths of four lemurs that developed severe neurological symptoms, including brain inflammation and seizures, before passing away.
Alarmingly, investigators traced the source of one animal's infection back to a public "lemur yoga" session, where an asymptomatic human carrying the virus likely transmitted it through close physical contact.
While HSV-1 is a highly common and largely harmless nuisance for humans—affecting nearly two-thirds of the population under 50 with nothing more than an occasional cold sore—it represents a swift death sentence for lemurs.
Because these primates never evolved a biological tolerance to the human virus, it rapidly attacks their nervous systems.
Unlike accredited institutions that enforce strict biosecurity protocols like wearing masks, private animal encounters often bypass these measures, prompting experts to warn that humans must recognize the invisible dangers they pose to vulnerable species.
