Preparation for Possible Bird Flu Spread in Humans by FDA

Introduction

Dr. Robert Califf, Commissioner of the U.S. Food and Drug Administration (FDA), announced on May 8 that the agency is preparing for a potential scenario where the highly pathogenic avian influenza, also known as bird flu or H5N1, could start spreading among humans.

Current Situation

The bird flu virus, like all viruses, is constantly mutating. Although it has recently started spreading among cattle and other species, so far, there are no signs of it transmitting from person to person. However, the FDA is actively preparing for the possibility of such a scenario. This includes developing treatments, tests, and vaccines in case the situation changes.

Concerns and Risks

Even though the patient in Texas who was confirmed to have the virus only experienced inflamed eyes as a symptom, the real concern is that the virus could jump to the human lungs. In such cases, the mortality rates have been observed to be as high as 25% in other parts of the world during brief outbreaks. This concern is based on how viruses typically mutate, as seen in the case of COVID-19.

Global Impact

From 2003 to April 1, 2024, 889 cases of H5N1 have been confirmed worldwide, with a fatality rate of 52%, according to the World Health Organization (WHO). The virus has developed into a "global zoonotic animal pandemic", raising concerns among scientists about its potential to evolve and spread among humans.

Preventive Measures

While the risk is still low, the FDA believes that instituting countermeasures now could reduce the spread of the virus and decrease the likelihood of a mutation that could affect humans. These countermeasures include testing cattle before moving them to another state and advising farm workers to wear protective equipment when dealing with potentially infected animals.

Ensuring Food Safety

Part of the FDA's focus is ensuring the safety of the country's milk supply. Tests on milk samples from grocery stores have been conducted, and while some tested positive, no live virus has been detected, indicating that the milk supply is safe. Similarly, tests on beef have confirmed its safety as well.

Conclusion

The FDA has confirmed H5N1 infections in 36 herds across nine states, and data indicates that H5N1 began circulating in cattle in late 2023. While about 70 farm workers in Colorado are being monitored, none have displayed symptoms as of yet.
