Welcome to "Avian Flu Watch: Global H5N1 Tracker." Today, we're monitoring the worldwide spread of bird flu.
**Global Hotspots and Case Numbers:**
Cambodia remains the most active human hotspot, with recent cases reported in January and February 2025. The country has seen a consistent rise in infections linked to poultry contact. In the Americas, the H5N1 virus has been detected in multiple countries, including the United States, where a significant number of poultry outbreaks have occurred.
**Trend Lines and Comparative Statistics:**
Visualization of trend lines shows a notable increase in cases over the past year, particularly in Southeast Asia. The case fatality rate for H5N1 remains high at about 48%, according to the World Health Organization.
**Cross-Border Transmission:**
Migration patterns of wild birds play a critical role in the global spread of H5N1. Recent reassortments have been identified in the Greater Mekong Subregion, highlighting the need for coordinated regional surveillance.
**Containment Efforts:**
Containment successes have been observed in countries enforcing strict biosecurity measures. However, failures often result from inadequate monitoring and reporting.
**Emerging Variants:**
Clade 2.3.4.4b continues to be a concern for its potential to infect non-avian species.
**Travel Advisories:**
Travelers are advised to avoid close contact with poultry and wild birds, especially in high-risk areas.
