The CNPRC is a research facility and is not open to the general public. This is because humans may carry diseases that can be extremely dangerous to the monkeys. Diseases carried by both humans and monkeys may also be fatal if contracted by the other species. All CNPRC employees are subject to annual health screenings to ensure they do not place the animals at risk of contracting human disease. The Center’s veterinarians, animal care staff, and scientific staff are all trained extensively in the appropriate safety procedures and ensure the prevention of the transmission of diseases.
