Bird flu, also known as Avian influenza, is a highly contagious viral infection that primarily affects birds but can also infect humans and other animals. The disease is caused by influenza A viruses, with H5N1 and H7N9 being among the most concerning strains due to their potential to cause severe illness and high mortality rates in humans. Understanding the risks, symptoms, transmission, and preventive measures associated with bird flu is essential for controlling its spread and protecting both public health and poultry industries. At TX Hospitals, we are committed to raising awareness about the risks, symptoms, transmission, and preventive measures of bird flu, ensuring that our community stays informed and protected. We offer comprehensive care for respiratory illnesses, including avian influenza, making us one of the best lungs hospitals in Hyderabad.
What is Bird Flu?
Avian influenza, or bird flu, is a type of influenza virus normally spread among wild aquatic birds but also infect domestic birds such as chickens, ducks, and turkeys. However many strains of the virus can leap to humans, frequently by direct exposure to infected birds or infected environments. Common Strains of Bird Flu:
- H5N1: A highly pathogenic strain that triggers a massive number of bird flu outbreaks across the globe. In humans, it has a high mortality rate, causing severe disease and respiratory insufficiency. it is particularly upsetting because if the virus evolves to be more easily transmissible between humans, we can find ourselves in a global health crisis
- H7N9: This is another subtype that can infect humans, first identified in China in 2013. H7N9 does not have any internationally known mortality rates, unlike H5N1 (however, it has caused severe illness in humans). Bird flu primarily spreads via infected birds and there are fears it could develop mutations that would allow it to spread more easily between humans.
- Avian flu subtype H5N8 is primarily avian in nature but has not infected humans to date. While it represents no threat to humans, the disease is highly contagious in poultry, able to cause large scale outbreaks and slaughter of infected birds. Though it has not yet appeared in human cases, H5N8 is still a significant public health and agricultural risk.
How is Bird Flu Transmitted?
Bird flu primarily spreads through:
- Direct contact: Handling infected birds, whether alive or dead, increases the risk of infection.
- Contaminated surfaces: The virus can survive on surfaces, such as farm equipment, clothing, and footwear, leading to indirect transmission.
- Inhalation of droplets: Inhaling droplets from the respiratory secretions of infected birds can transmit the virus.
- Consumption of undercooked poultry: Although rare, consuming infected poultry that is not properly cooked may pose a risk.
- Human-to-human transmission: While currently limited, mutations in avian influenza viruses could potentially lead to sustained human transmission.
Symptoms of Bird Flu in Humans
The symptoms of bird flu in humans vary depending on the strain but may include:
- High fever (above 38°C or 100.4°F)
- Cough and sore throat
- Muscle aches and fatigue
- Difficulty breathing or pneumonia
- Eye infections (conjunctivitis)
- Nausea, vomiting, or diarrhea in some cases
Severe cases can lead to acute respiratory distress syndrome (ARDS), multi-organ failure, and even death, especially in individuals with weakened immune systems. TX Hospitals, with best lungs doctors in Hyderabad, is equipped with state-of-the-art facilities to treat these severe symptoms, ensuring patients receive timely and expert care.
Preventive Measures for Bird Flu
For Poultry Farmers and Industry Workers
- Implement strict biosecurity measures on farms, including restricted access and disinfection protocols.
- Regularly vaccinate poultry in high-risk areas to prevent the spread of avian influenza.
- Avoid contact with sick or dead birds and promptly report unusual bird deaths to veterinary authorities.
- Ensure proper disposal of poultry waste and maintain hygienic farming conditions.
For the General Public
- Avoid live bird markets, especially in regions with active bird flu outbreaks.
- Do not handle sick or dead birds without protective gear.
- Cook poultry and eggs thoroughly to an internal temperature of at least 165°F (75°C) to eliminate any potential virus.
- Wash hands thoroughly after handling raw poultry or bird-related products.
- Stay informed about public health advisories and vaccination campaigns against influenza.

Bird flu remains a significant threat to both the poultry industry and public health. Preventive measures, early detection, and strict biosecurity protocols can help control outbreaks and minimize risks.
