Abstract Introduction :  Recent intercontinental spread of highly pathogenic avian influenza (HPAI) A( H5N1 ) among kept and wild birds, and transmission to mammalian hosts , including cattle and humans , has heightened the need to review public health risk assessments . Biosecurity is essential for limiting disease spread, but how widely practices are implemented is not fully known.  Methods :  Here, we report on uptake of biosecurity measures and risk perception of avian influenza virus (AIV) in the context of preventing zoonotic transmission to persons potentially at high risk of exposure. Questionnaire data from 225 people in contact with birds in the UK (Avian Contact Study, May to July 2024) was analysed.  Results :  We found hand washing after contact with birds was the most common biosecurity measure implemented (89%, 196/218), followed by using disinfecting footwear dips (78%, 170/218). Individuals in contact with a higher number of birds were more like...

Abstract Recent intercontinental spread of highly pathogenic avian influenza (HPAI) A(H5N1) among kept and wild birds and transmission to mammalian hosts , including cattle and humans has heightened the need to review public health risk assessments . Biosecurity is essential for limiting disease spread, but how widely practices are implemented is not fully known. Here, we report on the uptake of biosecurity measures using questionnaire data collected in 2024 from people in contact with birds in the UK (Avian Contact Study). Almost half of the sample were poultry farmers (104/225). We found hand washing after contact with birds was the most common biosecurity measure implemented (89%, 196/218), followed by using disinfecting footwear dips (78%, 170/218). Individuals in contact with a higher number of birds were more likely to use at least one PPE measure for the face or body (χ^2 (1, n=217) = 32.452, p<0.001) or at least one footwear-related PPE measure (Df=1, n=217, p<0.001), ind...

ABSTRACT Objectives Highly pathogenic avian influenza (HPAI) poses an occupational risk for poultry workers, responders, and others in contact with infected birds. The objective of this analysis was to describe HPAI surveillance methods and outcomes , and highlight the challenges, successes, and lessons learned during the Minnesota Department of Health’s (MDH’s) public health response to HPAI outbreaks in Minnesota poultry flocks in the years 2015 and 2022–2023. Methods During both outbreaks, MDH staff attempted to contact all potentially exposed people and conduct a standardized interview . People were considered exposed and at risk if they had entered a barn with poultry on any HPAI test-positive premises. With their consent, exposed persons were entered into illness monitoring until 10 days from their last exposure. In 2015, MDH monitored the health of poultry workers only. In the 2022–2023 response, MDH monitored the health of poultry workers, backyard flock owners, responders, and...

 {Summary} At a glance -- H5N1 bird flu is caused by viruses that can infect cows and other animals but most commonly affect birds and poultry .  -- People who work with infected animals or their byproducts (for example, raw milk ), might get sick from the virus.  -- For example , dairy and poultry workers might get sick with H5N1 bird flu.  -- Your employer should develop a workplace health and safety plan and share it with you.  -- CDC updated this page to add information about worker exposure levels (low, medium, and high).  -- We also added detail about how to use the right personal protective equipment safely for each exposure level.
