An outbreak of Pathogenic Avian Influenza (H5N1), commonly known as bird flu, has been confirmed in Kano State, Nigeria, affecting poultry such as layers, ducks, guinea fowls, and turkeys. This highly contagious virus poses a serious threat to poultry farms and, in rare cases, can infect humans through direct contact with sick birds, contaminated environments, or undercooked poultry products.
While human-to-human transmission is uncommon, past outbreaks have shown that the H5N1 virus can cause severe respiratory illness in infected individuals. Understanding the risks, symptoms, and preventive measures is crucial for both the public and healthcare professionals.

What Are the Risks of catching Bird Flu?
For the general public, especially those who work with poultry, the risk of exposure is highest through:
- Handling infected birds (alive or dead)
- Contact with bird droppings or contaminated surfaces.
- Consuming undercooked poultry or eggs
- Visiting live bird markets
For medical laboratory scientists and healthcare workers, the main risks involve:
- Exposure to patient samples from suspected cases
- Poor biosafety practices during sample collection and processing
- Cross-contamination in laboratory settings
Symptoms of Bird Flu in Humans
Symptoms of avian influenza in humans can range from mild flu-like illness to severe pneumonia and multi-organ failure. Common symptoms include:
- High fever (≥38°C)
- Persistent cough and sore throat
- Shortness of breath
- Muscle aches and fatigue
- Eye infections (conjunctivitis in some cases)
- Nausea, diarrhea, and vomiting (less common)
- Severe cases can lead to acute respiratory distress syndrome (ARDS), organ failure, and death if not detected early.
Diagnosis and Laboratory Testing
Early and accurate detection of H5N1 infections is critical. Medical laboratory scientists play a key role in identifying cases through proper sample collection and diagnostic testing.
1. Specimen Collection & Handling
Recommended samples: Nasopharyngeal/throat swabs, tracheal aspirates, bronchoalveolar lavage (BAL), and sputum
Transport in viral transport medium (VTM) under cold chain conditions
Ensure strict biosafety measures while handling specimens
2. Key Laboratory Tests for H5N1
RT-PCR: The gold standard for detecting Influenza A (H5N1)
Rapid Influenza Diagnostic Tests (RIDTs): Less sensitive but useful for preliminary screening
Serological Tests: For retrospective diagnosis in confirmed cases
* Viral Culture (BSL-3 facility required): Confirms live virus presence but is not routinely performed due to biosafety risks
Biosafety Precautions for Lab Scientists
- Work inside a Biosafety Cabinet (BSC-2)
- Wear full PPE (N95 mask, gloves, face shield, and lab coat)
- Use EPA-approved disinfectants for decontamination
- Dispose of biological waste according to lab safety protocols
Prevention & Control Measures
For the Public:
- Avoid contact with sick or dead birds
- Always cook poultry and eggs thoroughly
- Maintain good hand hygiene and avoid touching the face after handling birds.
- Report sudden poultry deaths to veterinary authorities
For Healthcare & Laboratory Workers:
- Follow strict biosafety protocols when handling samples
- Ensure proper PPE usage during sample collection and testing
- Conduct influenza surveillance in suspected cases
- Stay updated with public health guidelines from WHO, CDC, NCDC and Medlab HQ
Final Thoughts
The bird flu outbreak in Kano State is a significant public health concern, but early detection, proper safety measures, and public awareness can help prevent its spread. Medical laboratory scientists, veterinarians, and healthcare professionals must stay vigilant and ensure accurate diagnosis while the general public must take precautions when handling poultry.
📢 If you experience flu-like symptoms after poultry exposure, seek immediate medical attention and get tested. Early intervention saves lives!
Stay informed. Stay safe. Protect public health.
