Rimantadine (INN, sold under the trade name Flumadine [1]) is an orally administered antiviral drug [2] used to treat, and in rare cases prevent, influenzavirus A infection. When taken within one to two days of developing symptoms, rimantadine can shorten the duration and moderate the severity of influenza.
The test for this is based solely on the effect on chickens – a virus strain is highly pathogenic avian influenza (HPAI) if 75% or more of chickens die after being deliberately infected with it. The alternative classification is low pathogenic avian influenza (LPAI) which produces mild or no symptoms. [ 89 ]
Reasonably effective ways to reduce the transmission of influenza include good personal health and hygiene habits such as: not touching your eyes, nose or mouth; [6] frequent hand washing (with soap and water, or with alcohol-based hand rubs); [6] eating a diet rich in fruits and vegetables; [16] covering coughs and sneezes; avoiding close contact with sick people; and staying home yourself if ...
Influenza hemagglutinin (HA) or haemagglutinin [p] (British English) is a homotrimeric glycoprotein found on the surface of influenza viruses and is integral to its infectivity. Hemagglutinin is a class I fusion protein, [1] [2] having multifunctional activity as both an attachment factor and membrane fusion protein.
Influenza viruses A and B are estimated to have diverged from a single ancestor around 4,000 years ago, while the ancestor of influenza viruses A and B and the ancestor of influenza virus C are estimated to have diverged from a common ancestor around 8,000 years ago. [40] Outbreaks of influenza-like disease can be found throughout recorded history.
Influenza-like illness (ILI), also known as flu-like syndrome or flu-like symptoms, is a medical diagnosis of possible influenza or other illness causing a set of common symptoms. These include fever, shivering , chills , malaise , dry cough , loss of appetite , body aches, nausea , and sneezing typically in connection with a sudden onset of ...

Influenza C virus is the only species in the genus Gammainfluenzavirus, in the virus family Orthomyxoviridae, which like other influenza viruses, causes influenza. Influenza C viruses are known to infect humans and pigs. [1] Flu due to the Type C species is rare compared with Types B or A, but can be severe and can cause local epidemics.
