Recently, five workers at a Colorado poultry farm were infected with the H5N1 avian influenza virus. This news raised concerns about the possible spread of the virus between species and the potential risk to human health.
How the infection occurred
The virus, known to be highly pathogenic, was first detected in some dairy farms last year. The situation worsened when the virus jumped from wild birds to cattle, and then from cattle to chickens. The five infected workers were tasked with culling sick chickens and, due to high temperatures, failed to use adequate personal protection.
Symptoms and health status of workers
Fortunately, all cases had mild symptoms. Some workers had conjunctivitis, while others experienced common respiratory and flu symptoms, such as fever, chills, sore throat, runny nose, and cough. None of the workers required hospitalization.
Avian Influenza and the Ongoing Investigation
Health officials are still trying to figure out how the virus got to the poultry flock. Transmission of the virus from cattle flocks to poultry flocks is a possibility, but it remains to be confirmed. Eric Deeble, senior adviser for avian influenza response at the U.S. Department of Agriculture, said chickens are highly susceptible to avian influenza, and it doesn’t take much to infect an entire flock.
Sfide operative
Managing the outbreak is not easy. High temperatures have complicated the use of personal protection, making it difficult for workers to protect themselves adequately. Culling methods require direct and continuous contact with infected birds, increasing the risk of transmission.
This episode highlights the need for improved safety and prevention measures in culling operations, especially in extreme weather conditions. The CDC and USDA will continue to work together to investigate and develop effective strategies to prevent further transmission.
