Troubling Bird Flu Study Suggests Human Cases Are Going Undetected

A new study has raised alarm bells about the possibility of human cases of avian influenza (bird flu) going undetected, potentially leading to a wider outbreak.

The study, published in the journal [Nature] this week, analyzed data from a recent outbreak of H5N1 avian influenza in the United States. Researchers found that the virus was circulating widely among poultry, and that a significant number of people were exposed to the virus through close contact with infected birds.

However, despite the high exposure rates, only a handful of human cases were officially reported. This discrepancy, the study suggests, could point to a significant underreporting of human cases, potentially due to:

Mild or asymptomatic infections: The study found that many people exposed to the virus developed no symptoms, or only mild ones, making them less likely to seek medical attention and get tested.

Lack of awareness and testing: Some healthcare providers might not be aware of the latest guidance on bird flu testing, leading to missed opportunities for diagnosis.

Testing limitations: Current diagnostic tests for avian influenza in humans might not be sensitive enough to detect all cases, particularly those with mild symptoms.

The study's findings are particularly concerning given the potential for H5N1 to mutate and become more easily transmissible between humans. While the current strain of the virus is not easily transmissible between people, experts warn that continued exposure to infected birds could increase the risk of such mutations.

"This study is a wake-up call," said Dr. [Expert Name], a leading virologist and co-author of the study. "We need to be more vigilant in our surveillance and testing efforts to ensure that we are accurately capturing the true extent of human exposure and infection with avian influenza. Failing to do so could have devastating consequences."

The study's authors recommend the following actions to address the potential underreporting of human cases:

Increased surveillance and testing: Expanding surveillance efforts to include individuals at higher risk of exposure, such as poultry workers and those who handle birds, is crucial.

Improved awareness and training: Healthcare providers should be provided with up-to-date information and training on avian influenza diagnosis and treatment.

Development of more sensitive diagnostic tools: Research and development of more accurate and sensitive tests for avian influenza in humans is essential for early detection and effective response.

The study serves as a stark reminder of the ongoing threat posed by avian influenza and the importance of public health vigilance. With effective measures in place, we can mitigate the risks and prevent a potential pandemic.

Bird flu concerns as the virus jumps species

BOISE — (Below is verbatim of story that aired)

Coronavirus may be somewhat in the rear view mirror, but could the next pandemic come from birds? I'm senior reporter Roland Beres it's wellness Wednesday where we're healthier together and bird flu is hitting humans so I ask the experts how worried should we be?

From birds to cattle to humans, the avian flu is here, but doctors say it's nothing like Covid.

"it's certainly something we're watching but not panicking about or even markedly concerned about." said Dr. Daniel Meltzer.

The bird flu has recently infected six people working on a chicken farm in Colorado and there have been 11 US cases in humans since 2022.

But while flocks of birds are dying off or being culled, humans in the us have fared much better.

"Like most viruses there can be a spectrum from mild to moderate to severe so things like coughs fevers body aches it can progress to shortness of breath and more severe fevers which would require med attention." said Dr. Meltzer.

Worldwide, bird flu has killed close to 50 percent of the humans infected, which is high, but the CDC says it takes a large dose to be infected and the overall risk in the US is low.

But since viruses can mutate, a vaccine would be nice. Until that happens, at least there are effective treatments.

"Some of the antivirals we use for flu or Coronavirus have been effective in reducing severity of symptoms people get if they get bird flu." said Dr. Meltzer.

By the way, pasteurization kills the virus so the FDA says our milk supply is safe and no one has gotten bird flu from eating properly cooked eggs. Just avoid doing the Rocky move and drinking raw eggs. And it's advisable to avoid sunny side up or over easy eggs because they don't reach the necessary 165 degrees to kill the pathogen. For wellness Wednesday where we're healthier together, I'm Roland Beres Idaho news six.
