Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Wear face-masks to avoid transmission of viral and bacterial diseases to primates One study in Uganda found that a confiscated young chimpanzee was reunited with its mother after being handled by caretakers wearing face-masks, alongside other interventions. One before-and-after study in Rwanda, Uganda and the Democratic Republic of Congo found that numbers of mountain gorillas increased by 168% over 41 years while being visited by researchers and visitors wearing face-masks, alongside other interventions.

'No evidence' for an action means we have not yet found any studies that directly and quantitatively tested this action during our systematic journal and report searches. Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts.

Two before-and-after studies in the Republic of Congo found that 70% of reintroduced chimpanzees vaccinated against poliomyelitis and tetanus, alongside other interventions, survived over 3.5-5 years after release. One before-and-after study in the Republic of Congo and Gabon found that more than 80% of the reintroduced gorillas that received preventive vaccination, alongside other interventions, survived over a 10 year period.

One study in Brazil found that one out of four reintroduced black lion tamarins died after being release despite receiving treatment, alongside other interventions. One review on reintroduced lar gibbons in Thailand found that their population declined by 6% seventeen months after release despite having medical treatment available when sick or injured, alongside other interventions. One study in Malaysia found that 98% of translocated orangutans, some of which received treatment for injuries along with other interventions, survived capture and subsequent release. One controlled study, also in Malaysia, found that a population of reintroduced orangutans decreased by 33% over 33 years despite receiving treatment when sick or injured, alongside other interventions. Four studies, including two before-and-after studies, in Liberia, the Republic of Congo and The Gambia found that most reintroduced chimpanzees that were treated when sick, alongside other interventions, survived for at least 1-5 years and in one case the population increased. One study in Senegal found that a young chimpanzee was reunited with its mother after being treated for injuries, alongside other interventions. One before-and-after study in Uganda found that treatment for mange, alongside other interventions, cured some infected mountain gorillas. One study in Rwanda, Uganda and the Democratic Republic of Congo and one before-and-after, site comparison study in the Republic of Congo and Gabon found that most western lowland gorillas treated when sick or injured, alongside other interventions, survived over 4–41 years. Two before-and-after studies in South Africa and Indonesia found that most reintroduced or translocated primates that were treated when sick, alongside other interventions, survived over six months. However, two before-and-after studies in Madagascar and Kenya found that most reintroduced or translocated primates did not survived over five years or their population size decreased despite treated when sick, alongside other interventions.

One study in Brazil found that most reintroduced black lion tamarins that underwent veterinary screens, alongside other interventions, survived over four months. One before-and-after study in Malaysia found that 90% of reintroduced Müller's Bornean gibbons did not survive despite undergoing veterinary screens, alongside other interventions. One controlled study in Indonesia found that reintroduced Bornean agile gibbons that underwent veterinary screens, alongside other interventions, behaved similarly to wild gibbons. Two studies, including one controlled, in Malaysia and Indonesia found that most translocated orangutans that underwent veterinary screens, along with other interventions, survived translocation and the first three months post-translocation. Four studies, including three before-and-after studies, in Liberia, the Republilc of Congo and Guinea found that most reintroduced chimpanzees that underwent veterinary screens, alongside other interventions, survived over 1-5 years. One before and after study in Uganda found that a reintroduced chimpanzee repeatedly returned to human settlements after undergoing pre-release veterinary screens, alongside other interventions. Five studies, including four before-and-after studies, in Belize, French Guiana, Madagascar, Congo and Gabon found that most reintroduced or translocated primates that underwent veterinary screens, alongside other interventions, survived at least four months or increased in population size. Five studies, including four before-and-after studies, in French Guiana, Madagascar, South Africa and Vietnam found that most reintroduced or translocated primates were assumed to have died post-release despite undergoing pre-release veterinary screens, alongside other interventions. One controlled study in Kenya found that a population of translocated olive baboons were still surviving 16 years after translocation when veterinary screens were applied alongside other interventions.
