H5N1 outbreak: Cambodia reports 12th case this year; early symptoms to watch for

H5N1, or bird flu, initially presents with common flu-like symptoms such as fever, cough, and fatigue, making early detection challenging. The infection can rapidly escalate to severe breathing difficulties, confusion, and even pneumonia. Prompt medical attention and antiviral treatment within 48 hours of symptom onset are crucial for managing the illness effectively, especially for those with poultry exposure.
