Expanded Threat from Avian Influenza Virus Population - Escalating menace posed by avian influenza viruses
Growing Threat of Avian Flu Virus
Recent outbreaks of avian flu, particularly the H5N1 clade 2.3.4.4b, have been reported in U.S. dairy cows, raising concerns about the virus's potential to infect humans. The virus, known for its ability to adapt within animal species, has been detected in mammals such as cattle, dogs, and cats.
In the United States, the latest outbreak has been observed in cattle farms, displaying signs of mutation. The severity of human cases has been relatively mild, with one death among 70 confirmed cases. However, the OIE warns that avian flu poses a significant threat to agriculture, food security, trade, and ecosystems, as more than 630 million birds have died or been culled on farms over the past two decades.
Under the current U.S. administration, some funds for health and research institutions have been cut, which could potentially impact the response to avian flu outbreaks. The OIE stresses the importance of vaccinating farm animals, reducing the risk to humans, as well as close monitoring, precautions, comprehensive transparency, and international cooperation in combating the virus.
Climate change is thought to increase the overall risk of animal diseases jumping to humans. In 2021, a three-year-old girl died from avian flu in Mexico, and there were two reported deaths in Cambodia. Human transmission of the virus is mainly observed in individuals with close contact with infected animals.
To address the threat of avian flu, measures such as enhanced surveillance, vaccine development, strict biosecurity on farms, antiviral treatments, public health education, and collaborative research are essential components of a multi-faceted approach. By addressing this issue through a coordinated effort, the risk of further outbreaks and human infections can be mitigated effectively.
The Commission, amidst the growing threat of the avian flu virus, has also been asked to submit a proposal for a directive on the protection of workers from the risks related to exposure to ionizing radiation, as scientists in the field of environmental science believe that climate change increases the overall risk of animal diseases jumping to humans. Political leaders, in the midst of funding cuts to health and research institutions, are urged to prioritize allocations towards combating the avian flu, considering the significant impact the virus has on general news, agriculture, food security, trade, and ecosystems.
