The World Health Organization (WHO) has updated the list of the most dangerous viruses, bacteria and fungi that could trigger the next pandemic, Nature writes, UNN reports .
Details
The list includes more than 30 viruses and bacteria, including influenza A virus, dengue virus and smallpox viruses, monkeypox
The researchers explained that they selected the pathogens based on their potential threat to global health. The selection criteria were high contagion, virulence, and limited access to vaccines and treatments. At the same time, the experts emphasized that the list will not be permanent and is likely to be updated in response to global changes, such as climate change, urbanization and international travel.
The more than 30 priority pathogens now include groups of coronaviruses such as Sarbecovirus (including SARS-CoV-2) and Merbecovirus (including MERS). Monkeypox virus was also added following the 2022 outbreak, and smallpox virus remains on the list due to its potential use as a biological weapon.
The list also includes influenza A viruses, such as the H5 subtype, which caused an outbreak among cattle in the United States.
The five new bacteria include strains that cause cholera, plague, dysentery, diarrhea, and pneumonia. Two rodent viruses that have crossed over to humans also made the list due to the increased risk of transmission associated with climate change and urbanization. The Nipah virus, carried by bats, also remained on the list due to its high mortality and easy transmission to animals.
Virologists point out that many pathogens are limited to certain regions but have the potential to spread globally.
It is stated that the list is intended to help develop treatments, vaccines, and diagnostics.
