How is H1N1 influenza different from H5N1?
The H5N1 virus (red RNAs) is not transmissible among guinea pigs, while the H1N1 virus (green RNAs) has highly efficient transmission. Exchange of the H5N1 RNA coding for PA or NS from H1N1 produces a highly transmissible virus. Exchange of the H5N1 RNA coding for NA or M produces a less efficiently transmitted virus.
What is the symptoms of H5N1?
You may have an H5N1 infection if you experience typical flu-like symptoms such as:
- cough.
- diarrhea.
- respiratory difficulties.
- fever (over 100.4°F or 38°C)

History. A strain of H5N1 killed chickens in 1959 in Scotland and turkeys in 1991 in England. This strain was “highly pathogenic” (deadly to birds) but caused neither illness nor death in humans.
What does the H and N mean in H1N1 strain of influenza?
The designation “H1N1” indicates unique traits, which exhibit characteristics that identify the virus to the immune system and allows for attachment and replication of the virus. The “H” (hemagglutinin) and the “N” (neuraminidases) are both proteins that are found on the outer shell or envelope of the virus.
