Influenza A

The Influenza A virus causes influenza in birds and some mammals and is the only species of influenza virus A.
Influenza A viruses are negative sense, single-stranded, segmented RNA viruses.
The several subtypes are labeled according to an H number and an N number.
There are 18 different known H antigens (H1 to H18) and 11 different known N antigens (N1 to N11).
"Human influenza virus" usually refers to those subtypes that spread widely among humans.
H1N1, H1N2 and H3N2 are the only known influenza A virus subtypes currently circulating among humans.

  Symptoms include:

• rapid onset of fever
• headache
• muscle aches
• conjunctivitis
• fatigue
• sneezing
• running nose
• sore throat
• a cough.

Most people recover within a week, although the cough and fatigue may last longer.
Both the co driver and I have been laid low by this for nearly three weeks now.
Vaccinations against the virus are available but in many cases ineffective.
This disease is really one to avoid!
