Dutch researchers are studying the risks of pneumonia transmission to humans from pet guinea pigs, as a result of improper hygiene.
Researchers from Bernhoven Hospital found three cases of guinea pig-related pneumonia have occurred in the Netherlands over approximately three years.
The incidences involved two women and one man, all in their early 30s.
Out of the three cases, two patients were submitted to intensive care. They both had guinea pigs as pets who had recently shown respiratory symptoms.
