The World Health Organization (WHO) has updated its list of priority pathogens that could potentially trigger the next pandemic, now identifying over 30 dangerous viruses and bacteria. This list includes the influenza A virus, dengue virus, and monkeypox virus, which have been recognized for their high transmissibility and virulence, alongside limited access to vaccines and treatments. The updated report, released on July 30, highlights the need for focused research and resource allocation to address critical knowledge gaps regarding these pathogens. Notably, the list now encompasses entire families of viruses, such as Sarbecovirus, which includes SARS-CoV-2, and Merbecovirus, linked to MERS. The monkeypox virus, which caused a global outbreak in 2022, and the variola virus, responsible for smallpox, are also included due to concerns over potential outbreaks stemming from decreased immunity in the population. Additionally, several strains of influenza A and bacteria causing diseases like cholera and plague have been added. The report emphasizes the impact of climate change and urbanization on the transmission of these pathogens. Researchers have also compiled a separate list of 'prototype pathogens' to encourage further study and development of treatments and vaccines. The prioritization process aims to enhance preparedness for future public health emergencies, although experts caution that predicting the next emerging pathogen remains challenging.
