Bird Flu
Bird Flu Causes
Bird flu is caused by an avian influenza virus, which has three known strains: influenza A; influenza B; and influenza C. The bird flu virus is transmitted to humans through contact with infected poultry or exposure to surfaces contaminated by infected birds. It is more common in areas where humans live close to chickens and pigs. The disease starts with infected wild birds, which shed the virus through droppings, saliva, and nasal secretions. The virus is then transmitted to domesticated poultry via direct contact with these wild birds or through contaminated water, feed, or soil. Open-air markets where poultry and eggs are sold are breeding grounds for infection and spread the disease to a bigger population.
Bird Flu Definition
Bird flu is a disease commonly affecting wild and domestic birds that, when transmitted to humans, can be potentially fatal.
Bird Flu Diagnosis
Diagnosis of bird flu is based on clinical presentations and knowledge of possible exposure to contaminated regions or contact with infected poultry in areas with recent virus outbreaks. Swabs may be taken from the patient's throat and nose for laboratory analysis.
Bird Flu Symptoms and Signs
Bird flu presents with coughing, fever, sore throat, muscle aches, and conjunctivitis among infected humans. In severe cases, individuals with bird flu develop life-threatening complications such as viral pneumonia and acute respiratory distress.
Bird Flu Treatment
Antiviral medications such as oseltamivir (Tamiflu) and zanamivir (Relenza) are the current drugs of choice for treating bird flu.
