Macaques and baboons show success as models to study SARS-CoV-2 3 Researchers have shown rhesus macaques and baboons develop strong signs of acute viral infection from SARS-CoV-2, making them ideal models. Scientists have published their findings regarding a comprehensive animal model that can be used to study SARS-CoV-2. The research was conducted at Texas Biomedical Research Institute (Texas Biomed) and Southwest National Primate Research Center (SNPRC), US. The study evaluated three non-human primate (NHP) species (Indian rhesus macaques, African baboons and new-world origin common marmosets) and young and old animals, to determine susceptibility to the SARS-CoV-2 virus and the development of COVID-19 disease.
