The H5N1 pandemic, a looming threat to global health, has captured the attention of scientists, policymakers, and the public alike. This highly pathogenic virus has the potential to trigger a widespread outbreak with devastating consequences, prompting urgent action to mitigate its risks.
Understanding the nature of the H5N1 virus, its pandemic potential, and the strategies for prevention and control is crucial in preparing for and responding to this potential global health crisis.
H5N1 Virus Overview
The H5N1 virus is a highly pathogenic avian influenza virus that can cause severe respiratory illness in birds and humans. It is a subtype of the influenza A virus, which is responsible for causing seasonal influenza in humans.
H5N1 is primarily a bird virus, but it can occasionally infect humans through contact with infected birds or their secretions. Transmission occurs through the inhalation of respiratory droplets or contact with contaminated surfaces.
