The recent outbreak of bird flu has spread threats to the governments as several of the species have been badly affected and some died. But, what is this bird flu? And what causes it?
According to healthline, although there are several types of bird flu, H5N1 was the first avian influenza virus to infect humans. The first infection occurred in Hong Kong in 1997. The outbreak was linked to handling infected poultry. H5N1 occurs naturally in wild waterfowl, but it can spread easily to domestic poultry. The disease is transmitted to humans through contact with infected bird feces, nasal secretions, or secretions from the mouth or eyes.
Consuming properly cooked poultry or eggs from infected birds doesn’t transmit the bird flu, but eggs should never be served runny. Meat is considered safe if it has been cooked to an internal temperature of 165ºF (73.9ºC).
What are the symptoms of bird flu?
You may have an H5N1 infection if you experience typical flu-like symptoms such as:
- Respiratory difficulties
- Fever (over 100.4°F or 38°C)
- Muscle aches
- Runny nose
- Sore throat
If you’re exposed to bird flu, you should notify staff before you arrive at the doctor’s office or hospital. Alerting them ahead of time will allow them to take precautions to protect staff and other patients before caring for you.
