Paper shows that wild mammals that were at risk of extinction owing to human activities carried twice the zoonotic diseases compared to animals that were not at the same risk. Among threatened wildlife species, those with population reductions owing to exploitation and loss of habitat shared more viruses with humans. This has increased opportunities for animal-human interactions and facilitated zoonotic-disease transmission.

A new paper shows that the destruction of forests into fragmented patches is increasing the likelihood that viruses and other pathogens will jump from wild animals to humans.

A new paper, 26 March, describes multiple lineages of pangolin coronavirus and their similarity to the SARS-CoV-2. A previous study had suggested that Pangolins could be intermediate hosts. Although bats are likely reservoir hosts for SARS-CoV-2, this study says that pangolins should be considered as possible hosts in the emergence of novel coronaviruses and should be removed from wet markets to prevent zoonotic transmission. The study was done on Malayan pangolins (Manis javanica) seized in anti-smuggling operations in southern China. Pangolins are the world’s most trafficked animals.

Review identifies 1415 species of infectious organism known to be pathogenic to humans. Out of these, 868 (61%) are zoonotic, that is, they can be transmitted between humans and animals, and 175 pathogenic species are associated with diseases considered to be ’emerging’. Out of the emerging pathogens, 132 (75%) are zoonotic.
