CDC: 3 veterinarians had recent H5N1 infections but didn’t know they had been exposed to the virus
Today in Morbidity adn Mortality Weekly Report, the US Centers for Disease Control and prevention (CDC) reports on recent avian influenza A (H5N1) infections in three veterinarians who work with cattle but didn’t know they had been exposed to the virus. The CDCS analysis of blood samples from 150 bovine veterinarians in 46 US states and Canada during the current …
H5 Bird Flu Response: Focus Areas for Ongoing Public Health Risk
CDC continues to assess that the current H5N1 bird flu risk to the general public remains low. …(e.g.,veterinarians,wild animal facility workers) … What follows is a description of the epidemiological and virologic characteristics of the avian influenza situation that CDC scientists are tracking to formulate the agency’s immediate …More herd and bulk-milk testing needed
The results also confirm the importance of preventing H5N1 infections in animals and rapidly identifying infected dairy cattle through herd and bulk milk-testing programs, as the US Department of Agriculture announced in October, the researchers said. Increased testing of herds and bulk milking tanks can help monitor for additional A(H5) positive herds and help better protect bovine veterinary practitioners and other animal workers. surveillance programs, such as herd and bulk milk testing and serosurveys, can aid in identifying areas of increased risk to bovine veterinary practitioners and workers to allow for appropriate engineering controls, administrative controls, and personal protection equipment use.”
Bird Flu Risk to Humans: Findings and Solutions
Table of Contents
In a recent addition to the Morbidity and Mortality Weekly Report, the US Centers for Disease Control and prevention (CDC) detailed new evidence of avian influenza A (H5N1) spreading to humans. Three veterinarians had antibodies to the H5N1 virus, indicating recent infection, yet none of them were aware of any exposure to infected dairy cattle. This interview explores these findings and ongoing efforts to mitigate public health risks from bird flu with expert insights from Dr. Emily Thompson, a virologist specializing in avian influenza.
Emerging Evidence of Bird Flu Spread to Humans
Senior Editor, World-Today-News.com: Dr. Thompson, can you explain what the recent CDC report indicates about the spread of the H5N1 virus to humans?
Dr. Emily Thompson: The CDC report notes that three veterinarians showed antibodies to the H5N1 virus in their blood samples. This is significant because the presence of these antibodies suggests recent infection. The veterinarians were unaware they had been exposed to the virus while working with cattle, which underscores the potential risk to those in close contact with infected animals.
SE, World-Today-News.com: How does this evidence change the viewpoint on the avian influenza virus and its potential to infect humans?
Dr. emily Thompson: Previously, it was thought that the virus predominantly affected avian species. Though, this report highlights the possibility of human infection, even indirectly. the fact that these veterinarians unknowingly had the virus underscores the need for strict surveillance and infection control measures among animal handlers.
Public Health Risk Assessment
SE, World-Today-News.com: What is the current assessment of the risk of H5N1 bird flu to the general public?
Dr. Emily Thompson: The CDC continues to assess that the risk to the general public remains low. However, this does not negate the importance of vigilance. The potential risk is higher for specific groups, such as veterinarians and wild animal facility workers, who have more direct contact with infected animals.
SE, World-Today-News.com: What are the key focus areas for ongoing inquiry and mitigation of this risk?
Dr. Emily Thompson: The CDC is focusing on epidemiological and virologic characteristics of the avian influenza A (H5N1) situation. This includes regular surveillance, testing, and implementing strategies such as herd and bulk milk testing to rapidly identify infections.
Increased Testing and Surveillance
SE, world-Today-News.com: How crucial is increased testing and surveillance in managing and mitigating this risk?
Dr. Emily Thompson: Increased testing is vital. Surveillance programs like herd and bulk milk testing help detect infections in animals, which later aids in protecting human handlers. This two-pronged approach ensures that outbreaks are identified and contained promptly.
SE, World-Today-News.com: How can these surveillance programs help protect both animals and humans?
Dr. Emily Thompson: By frequently testing herds and milk tanks, we can monitor additional positive herds. This proactive approach enables the implementation of engineering controls, administrative controls, and personal protective equipment (PPE) for handlers, minimizing both animal and human exposure risks.
Concluding thoughts
Dr. Emily Thompson: The main takeaways are the potential for the H5N1 virus to infect humans, the need for increased surveillance of animals and handlers, and the importance of rapid identification and containment of infections. By enhancing our prevention and detection strategies, we can better protect both human and animal populations from the avian influenza virus.
