Bird Flu, Flu Season, and Protecting Your Health: What You Need to Know
While I typically focus on food and your health, pressing medical updates demand attention. Today, we’re tackling two critical topics: the latest on bird flu (avian influenza) and the rise in seasonal respiratory illnesses, including flu and COVID-19.
With public communication from federal agencies temporarily paused, it’s vital to stay informed. Here’s a comprehensive overview of what’s happening, what it means for you, and how to protect yourself and those around you.
Respiratory Illness Trends: Seasonal Flu on the Rise
As of January 24th, 2025, respiratory illnesses are driving more people to seek healthcare. Here’s what we’re seeing:
- Seasonal flu: Elevated and rising in some areas.
- COVID-19: Most regions report a decline in cases.
- RSV: Also trending downward.
Locally, we’re seeing these same trends, with flu activity increasing significantly.
Bird Flu: A Persistent Global Concern
Since 1997, HPAI A(H5N1) virus infections have been reported in over 925 people, with an alarming 50% case fatality rate. Early outbreaks included 20 cases and 7 deaths in Hong Kong between 1997 and 2003, and since November 2003, more than 900 cases across 24 countries have been documented (CDC).
Symptoms and Severity
HPAI A(H5N1) infections can range from mild to severe, including:
- Mild symptoms: Upper respiratory tract issues like a runny nose or sore throat.
- Severe symptoms: Pneumonia, respiratory failure, acute respiratory distress syndrome (ARDS), and multi-organ failure.
- Neurological impact: Some cases report encephalitis, a dangerous brain inflammation.
Since 2016, sporadic cases have been reported globally, and while rare, they highlight the virus’s ability to persist.
Notable Cases and Strains
A Sobering Case from Louisiana
A recent case in Louisiana reminds us of the risks associated with bird flu. A man died after handling wild birds infected with HPAI A(H5N1). This tragic event underscores how deadly the virus can be in humans.
Other Strains to Watch
- HPAI A(H5N6): Over 90 cases have been reported in China since 2014, with one additional case in Laos in 2021. This strain has a case fatality rate exceeding 50% (WHO).
- HPAI A(H5N8): Russia reported the first asymptomatic human case in a poultry worker in 2020 (CDC).
Testing and Monitoring
Hospitals now test anyone hospitalized with severe flu symptoms for bird flu. Public health officials use several tools to monitor these trends:
- Wastewater surveillance
- Emergency department visit data
- Lab-confirmed cases
These measures provide early warnings of emerging threats, helping to guide public health responses.
