Bird Flu Symptoms: Recognizing the Signs
Many initial symptoms of bird flu mimic those of the common flu, making early detection challenging. This makes understanding the subtle differences crucial. Symptoms typically appear within 2 to 10 days of exposure to the infected bird or contaminated environment.
Common Symptoms
- Fever or Feeling Feverish: While not always present, fever is a common early symptom.
- Cough: A persistent cough, sometimes producing mucus, is another frequent indicator.
- Sore Throat: Discomfort and pain in the throat are typical.
- Muscle Aches or Body Aches: Generalized body pain is common.
- Fatigue or Tiredness: Extreme tiredness and exhaustion are prevalent.
- Headache: Headaches can range from mild to severe.
- Runny or Stuffy Nose: Nasal congestion or a runny nose can occur.
- Pink Eye (Conjunctivitis) or Eye Redness/Irritation: This is particularly noteworthy, especially in recent cases of avian influenza A(H5) virus in the U.S.
- Shortness of Breath or Difficulty Breathing: This is a serious symptom that requires immediate medical attention.
- Nausea and Vomiting: Gastrointestinal symptoms can be present.
- Diarrhea: Loose or watery stools may accompany other symptoms.
Severe Symptoms and Complications
- High Fever: A significantly elevated temperature, often accompanied by chills.
- Severe Pneumonia: Inflammation of the lungs, leading to difficulty breathing and potential respiratory failure.
- Acute Respiratory Distress Syndrome (ARDS): A life-threatening condition where the lungs fill with fluid, impairing oxygen intake.
- Multi-organ Dysfunction or Failure: The virus can affect multiple organs, including the kidneys, liver, and heart.
- Septic Shock: A life-threatening condition resulting from a severe bloodstream infection.
- Altered Consciousness or Encephalopathy (Brain Disease): In severe cases, the virus can affect brain function.
- Seizures: Uncontrolled electrical activity in the brain.
- Worsening of Chronic Lung Conditions: Existing conditions like asthma or cystic fibrosis can be significantly exacerbated.
- Ear and Sinus Infections: Secondary infections can occur due to a weakened immune system.
- Bleeding in the Lungs or Collapsed Lung: Severe complications affecting respiratory function.
- Bacterial Pneumonia: A secondary bacterial infection can further complicate the illness.
- Rhabdomyolysis (Muscle Breakdown): Breakdown of skeletal muscle tissue, potentially leading to kidney damage.
- Death: In severe cases, bird flu can be fatal, particularly if medical intervention is delayed.
