A study by the University of Pretoria warns that human-to-animal transmission of the virus “poses a risk to large cats in prisons.”
The report underscores that animals can be affected by “the most severe form of the disease”, especially as PCR tests show that cats remain positive until seven weeks of age.
The study was launched last year after three African lions tested positive for Kovit-19. They had human-like symptoms: difficulty breathing, runny nose, cough. A lion has developed pneumonia.
Five zoo staff who were in contact with the animals tested positive, saying the origin of the infection came from humans.
The sequence of experiments established that it was a delta variant and then dominated in South Africa.
One year ago, two puma showed signs of loss of appetite and diarrhea and runny nose.
Three weeks later they recovered. In their case, the source or variation of the contaminant could not be determined.
